See "For many of these treatments there is little clinical evidence supporting efficacy. Kombucha is an extreme example in several ways: there is no convincingly positive clinical evidence at all; the claims for it are as far reaching as they are implausible; the potential for harm seems considerable. In such extreme cases, healthcare professionals should discourage consumers from using (and paying for) remedies that only seem to benefit those who sell them. In conclusion, none of the numerous health claims for Kombucha is supported by clinical evidence. The consumption of Kombucha tea has been associated with serious adverse events. Its therapeutic use can therefore not be recommended."[1] It appears the content is sourced. QuackGuru (talk) 17:17, 31 May 2018 (UTC)
I am not seeing the content you presented in the article you linked to. Instead of adding our own words, why can’t we just stick to the facts presented in the article referenced (https://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0020339/):
“The author concluded that the claimed benefits of Kombucha were not supported by clinical evidence and, in view of the adverse events profile, its therapeutic use could not be recommended. However, he also noted that the adverse events were described in isolated reports, which cannot allow firm conclusions about causality and allow for generalisation.”
And:
“The author concluded that the therapeutic use of Kombucha could not be recommended owing to the lack of clinical efficacy and associated serious adverse events.”
Or, use actual quotes from the new link you provided? WikiGJay (talk) 17:53, 31 May 2018 (UTC)
- Adding quotes usually does not have an encyclopedic feel. We don't replace sourced content with quotes without an exceptional reason. I quoted the text from the PDF file. You provided a link to the summary rather than the entire review. If you don't have a copy of the PDF file then you can go request to get a copy. The link I provided does link to the DOI. You stated "I am not seeing the content you presented in the article you linked to. Instead of adding our own words, why can’t we just stick to the facts presented in the article referenced (https://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0020339/). The content I restored is sourced per this and is sticking to the facts presented in the review.
- See WP:NOABSTRACT: "However, when it comes to actually writing a Wikipedia article, it is misleading to give a full citation for a source after reading only its abstract; the abstract necessarily presents a stripped-down version of the conclusions and omits the background that can be crucial for understanding exactly what the source says, and may not represent the article's actual conclusions.[16] To access the full text, the editor may need to visit a medical library or ask someone at the WikiProject Resource Exchange or WikiProject Medicine's talk page to either provide an electronic copy or read the source and summarize what it says; if neither is possible, the editor may need to settle for using a lower-impact source." I have read and cited the full citation. The abstract and summary represent only a small piece of the citation. QuackGuru (talk) 18:22, 31 May 2018 (UTC)
Sorry, I should have been more specific. I did not mean to imply that we should add paragraphs of quotes.
Unfortunately, I do not have a log in for the Karger link you provided - so I will rely on your knowledge about the PDF. The link I used was from the article itself - and from the link you provided.
If the author stated "an extreme example of an unconventional remedy, tell us that this is what the author stated. Otherwise, taking your words:
1) “there is no convincingly positive clinical evidence at all, the claims for it are as far reaching as they are implausible” But, there has been “plausable” evidence since 2001, the cut-off date of the 2003 systematic review. See https://www.healthline.com/nutrition/8-benefits-of-kombucha-tea#section1 for links to the “Evidence-Based Health Benefits of Kombucha Tea”:
- there are multiple studies about the benefits of green tea
- "Rat studies consistently find that drinking kombucha regularly reduces liver toxicity caused by toxic chemicals, in some cases by at least 70%" (https://www.ncbi.nlm.nih.gov/pubmed/19420997, https://www.ncbi.nlm.nih.gov/pubmed/14631833,https://www.ncbi.nlm.nih.gov/pubmed/11723720, https://www.ncbi.nlm.nih.gov/pubmed/21388793)
- "Rat studies find that Kombucha can greatly improve two markers of heart diseases, LDL and HDL cholesterol" (https://www.ncbi.nlm.nih.gov/pubmed/22591682, https://www.ncbi.nlm.nih.gov/pubmed/25856715)
- "A study in diabetic rats found that kombucha slowed down the digestion of carbs, which reduced blood sugar levels." (https://www.ncbi.nlm.nih.gov/pubmed/22591682)
So, to not mislead the readers, perhaps say something like: "The author found no convincingly positive clinical evidence through 2001, the end-point of the research."
2) “the potential for harm seems considerable”. But the “FDA says Kombucha is safe when properly prepared.” See https://www.webmd.com/diet/the-truth-about-kombucha
So, maybe, given the newer evidence, say: "The author identified various adverse events, including x, y, z.
3) "In such extreme cases, healthcare professionals should discourage consumers from using (and paying for) remedies that only seem to benefit those who sell them”. What extreme case? And - can you give a quote where the study analyzes Kombucha sales and who is benefitting from these sales?
So, maybe something like: "Given the lack of research proving Kombucha benefits in pre-2002 research and the risks the author found, the author determined that the therapeutic use of Kombucha could not be recommended"
4) “none of the numerous health claims for Kombucha is supported by clinical evidence.” - See the studies quoted, above, So, minimally, add "through 2001, the study's cut-off date".
5) “The consumption of Kombucha tea has been associated with serious adverse events.” But yet, even the author of the 2003 study says “the adverse events were described in isolated reports, which cannot allow firm conclusions about causality and allow for generalisation” See https://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0020339/ . You have the PDF, though, so you have more details.
And - in the case where readers do not have access to the source, I feel that direct quotes to prove your points would really help (even though they are discouraged). Otherwise, how can the common reader of Wikipedia discern what is true and what is editorialized?
Thanks! When I get a chance, I will add the post-2001 studies to the Health Claims section.WikiGJay (talk) 20:28, 31 May 2018 (UTC)
So - to summarize my lengthy explanation, the article's paragraph should be changed to something like:
"A 2003 systematic review characterized Kombucha as an unconventional remedy because Ernst, the author of the study, could not find any pre-2002 clinical evidence to support any of Kombucha’s wide-ranging health claims. So, given the potential for harm that Ernst found Kombucha to have, he concluded that the number of proposed, unsubstantiated, therapeutic benefits did not outweigh the known risks. Therefore, he concluded that Kombucha should not be recommended for therapeutic use.[4]"
Not much different - I basically just added the "pre-2002" emphasis. Thanks!WikiGJay (talk) 20:50, 31 May 2018 (UTC)
- You are not relying on my knowledge about the PDF. I quoted part of the conclusion directly from the PDF file where it verified the claim you disputed. You can easily get a copy. See WP:REREQ. Your objection was the content failed verification. Now that it is sourced there is not a strong reason the content should not be restored. The post-2001 studies do not seem to be compatible with WP:MEDRS. So, to not mislead the readers, we should not use studies or primary sources to argue against reviews. Wording such as "the author of the study, could not find any pre-2002 clinical evidence" and "he" is weakening the claim and is needless words. QuackGuru (talk) 21:16, 31 May 2018 (UTC)
Is the actual quote "'extreme example' of an unconventional remedy" in the PDF? And, does the PDF talk about “profit”?WikiGJay (talk) 21:46, 31 May 2018 (UTC)
- Please request a copy of the source. See WP:REREQ. That way you can read it yourself. QuackGuru (talk) 01:38, 1 June 2018 (UTC)
You wrote the "'extreme example' of an unconventional remedy" and the "profit" statements - I would assume that you can defend the statements with sourced quotes. Otherwise, let's just let the current paragraph stay. After all, I didn't change the paragraph that much...WikiGJay (talk) 01:53, 1 June 2018 (UTC)
- See "For many of these treatments there is little clinical evidence supporting efficacy. Kombucha is an extreme example in several ways: there is no convincingly positive clinical evidence at all;..."[2] Verifies "extreme example".
- See "Unconventional remedies such as Kombucha are increasingly popular, not least because they are supported by frequent and favourable media coverage[15].[3] Verifies "unconventional remedy".
- See "In such extreme cases, healthcare professionals should discourage consumers from using (and paying for) remedies that only seem to benefit those who sell them."[4] Verifies "Kombucha only appears to benefit those who profit from it, according to a 2003 review." For those who "sell" they profit from it. We don't copy sources. It is a similar word per this. QuackGuru (talk) 02:32, 1 June 2018 (UTC)
Wow - I am surprised that a researcher would editorilize that way. But, you are pulling direct quotes from the study, so it is what it is. I would highly recommend that you ensure that you attribute the quotes to the author so readers do not think that YOU are editorilizing - especially since 99% of the readers will never see the full text.
That means, though, that another paragraph with newer research is really needed, or else we are mis-leading the readers. For, as I mentioned before, there have been newer studies.
For example, see the article "Understanding Kombucha Tea Fermentation: A Review" in the peer-reviewed Journal of Food Science found at https://onlinelibrary.wiley.com/doi/full/10.1111/1750-3841.14068. Under the "Biological Activities" section, this article sites 3 different studies about Kombucha benefits, which contradicts the 'extreme example' and 'profit' statements. WikiGJay (talk) 15:29, 1 June 2018 (UTC)
- The content you deleted was not restored. Do you agree it is now sourced and can be restored? After we are done here and will read the PDF file of the source you found. I want to finish up here and then start to add content from the new source you found. QuackGuru (talk) 15:58, 1 June 2018 (UTC)
Go ahead and restore it - it is what the author said, even though he was editorializing.
This is still draft mode, but I am thinking that a paragraph such as the below needs to be added then:
Since 2003, there have been several rat studies that point to potential Kombucha benefits for rats with diabetes, electromagnetic radiation, and liver and kidney toxicities due to cholesterol-rich diets. There have also been many “in vitro’ evaluations since 1998 that point to Kombucha benefits. However, more studies and evaluations are needed to confirm the health benefits of Kombucha definitively.
https://onlinelibrary.wiley.com/doi/full/10.1111/1750-3841.14068 . WikiGJay (talk) 16:08, 1 June 2018 (UTC)
- I'd rather not add content about rats when there is content about side effects to humans. For medical content, we usually don't add more studies are needed. QuackGuru (talk) 16:14, 1 June 2018 (UTC)
This is from a peer-reviewed journal - who are we to dispute that? The above paragraph does state that the studies are rat studies. And it is the authors of the article I reference who say that more studies are needed - not me (so, maybe I should attribute the 'more studies' content to the authors).
And, there is a WHOLE section about the adverse effects of Kombucha in the article already, so that has been covered. Plus, the U.S. Food and Drug Administration has reported that Kombucha tea is safe for human consumption, so it is not like Kombucha is a poison. WikiGJay (talk) 16:27, 1 June 2018 (UTC)
- Citing evidence to a review about rat studies is weaker evidence. Adding 'more studies are needed' does not tell the readers much and for medical articles editors usually avoid adding such content. QuackGuru (talk) 16:38, 1 June 2018 (UTC)
Fine - then add the fact that rat studies are weaker evidence (with a source). Plus, change the last sentence:
Since 2003, there have been several rat studies that point to potential Kombucha benefits for rats with diabetes, electromagnetic radiation, and liver and kidney toxicities due to cholesterol-rich diets. There have also been many “in vitro’ evaluations since 1998 that point to potential Kombucha benefits. (Add your point about rat stuides and, possibly, "in vitro" here). However, the health benefits of Kombucha cannot be definitively proven until there are human studies.
This provides the reader with what has happened in the last 17 years since the 2003 study (which only studied research through 2001). WikiGJay (talk) 16:50, 1 June 2018 (UTC)
- Content about rats does not add much to the article because we have more solid research based on humans in the article. See WP:MEDANIMAL. QuackGuru (talk) 17:02, 1 June 2018 (UTC)
No - we do not have 'solid' research since the research in the Wikipedia page is more than a decade old.
And, who are we to censor secondary, peer-reviewed, up-to-date, 2018 content? Certainly, Wikipedia wants readers to know what has happened in the last 17 years.
So - per the medical link you provided, I changed the paragraph to the below.
Since 2003, there have been several rat studies that point to potential Kombucha benefits for rats with diabetes, electromagnetic radiation, and liver and kidney toxicities due to cholesterol-rich diets. There have also been many “in vitro’ evaluations since 1998 that point to Kombucha benefits. However, in vitro and animal-model findings do not translate consistently into clinical effects in human beings, so human studies are needed to definitively prove Kombucha benefits. WikiGJay (talk) 17:39, 1 June 2018 (UTC)
- I'm not sure why you are bring up rats again per WP:MEDANIMAL. I could not verify "However, in vitro and animal-model findings do not translate..." QuackGuru (talk) 18:47, 1 June 2018 (UTC)
I already stated why we need to bring the readers up to date with the research in the last 17 years - please read my previous statement.
The medical link you gave states:
"Where in vitro and animal-model data are cited on Wikipedia, it should be clear to the reader that the data are pre-clinical, and the article text should avoid stating or implying that reported findings hold true in humans. The level of support for a hypothesis should be evident to a reader."
I did that. WikiGJay (talk) 18:55, 1 June 2018 (UTC)
- I stated above, I could not verify "However, in vitro and animal-model findings do not translate...". QuackGuru (talk) 18:59, 1 June 2018 (UTC)
"However, in vitro and animal-model findings do not translate consistently into clinical effects in human beings." See WP:MEDANIMAL, under the "Avoid over-emphasizing single studies, particularly in vitro or animal studies" section. WikiGJay (talk) 19:01, 1 June 2018 (UTC)
- That is not sourced to the paper. You insisted content from the paper should be included. I added a sentence based on a conclusion of the Biological Activities section. QuackGuru (talk) 19:08, 1 June 2018 (UTC)
Okay - from the article:
Since 2003, there have been several rat studies that point to potential Kombucha benefits for rats with diabetes, electromagnetic radiation, and liver and kidney toxicities due to cholesterol-rich diets. There have also been many “in vitro’ evaluations since 1998 that point to Kombucha benefits. However, more investigations and evaluations are needed to confirm Kombucha benefits.

- "Since 2003" is misleading because the research was not from 2013 to 2018. The word point is a weasel word that is not neutral. The word potential is misleading. QuackGuru (talk) 19:19, 1 June 2018 (UTC)

Since the 2003 research found absolutely no research confirming the benefits, this paragraph needs to be a separate paragraph after the 2003 research so as not to confuse readers:
As documented in 2018, several in vitro studies have been done for Kombucha which were in 1998, 2000, 2011, 2012, 2014, 2016, and 2017 as well as several researchers have done in vivo studies using rats from 2013 to 2015 for Kombucha in the areas of diabetes, electromagnetic radiation, and liver and kidney toxicities due to cholesterol-rich diets, but the results of biological activities have not been confirmed for the purported health benefits in humans.WikiGJay (talk) 20:11, 1 June 2018 (UTC)

- This single sentence does not need to be into a separate paragraph by itself.
- This is similar to your wording. I can't say if another editor would delete it. I have seen editors on other articles delete content mentioning rats. You can try to add it. QuackGuru (talk) 20:26, 1 June 2018 (UTC)
Ok - thanks. I broke the content into 2 sentences and added it as a separate paragraph since it flows better (a paragraph for 2000, a paragraph for 2003, and a paragraph for 2018). I also added the "Journal of Food Science" to help other editors see that the content came from a peer-reviewed journal. WikiGJay (talk) 20:41, 1 June 2018 (UTC)
- Adding the name of the journal such as "in the Journal of Food Science" is usually avoided because it clusters the article with needless words. Usually the newer source is placed in front of the older source for medical related content. QuackGuru (talk) 20:54, 1 June 2018 (UTC)

Comments on RfC on adding current research status
It's unencyclopedic primary research in test tubes or lab animals, of no relevance to possible effects from human consumption, leading to conjecture. Contrary to the J Food Sci report, it has no proven anti-inflammatory or antioxidant effects, nor could it have as a consumed beverage digested in stomach enzymes and acids which destroy native compounds in the tea. Fails WP:MEDASSESS. --Zefr (talk) 18:21, 12 June 2018 (UTC)
- Not adding current updates, though, leaves people to conjecture that the content presented has a high probability of being inaccurate because new information is not being presented (especially given the editorialized comments by the author of the 2003 study). The 2018 peer-reviewed J Food Sci report basically summarizes where we are now, ie, studies up to 2018 have proven no health benefit for humans.WikiGJay (talk) 18:49, 12 June 2018 (UTC)
- It is a 2018 review commenting on the primary research. The title of the paper confirms it is a review. See "Understanding Kombucha Tea Fermentation: A Review". A recent review passes WP:MEDASSESS. QuackGuru (talk) 18:56, 12 June 2018 (UTC)
- Better to leave out lab research which is unlikely to be reliably duplicated per WP:MEDANIMAL, and state there is no evidence as of 2018 that kombucha has any health benefits. Leaving it in conveys misinformation in the J Food Sci article to non-science encyclopedia users; WP:NOTJOURNAL, #7. --Zefr (talk) 19:04, 12 June 2018 (UTC)
- Since we are citing a review for the lab research it meets WP:MEDRS. Per WP:MEDANIMAL: Where in vitro and animal-model data are cited on Wikipedia, it should be clear to the reader that the data are pre-clinical, and the article text should avoid stating or implying that reported findings hold true in humans." The text is clear what type of studies were conducted and does not imply it holds true for humans. See the wording in the proposal, "However, the results of biological activities have not been confirmed for the purported health benefits in humans." This confirms the lack of any health benefits in humans. Per WP:NOTJOURNAL, #7: "A Wikipedia article should not be presented on the assumption that the reader is well-versed in the topic's field." The text is well written and clear. Therefore, the readers do not need to be well-versed in the topic to understand the text. QuackGuru (talk) 19:20, 12 June 2018 (UTC)

I don't understand why we should censor information from an actual, recent, peer-reviewed review of multiple studies. Should we, as editors, be questioning what the experts said? Plus, the line "However, the results of biological activities have not been confirmed for the purported health benefits in humans" was added. WikiGJay (talk) 19:19, 12 June 2018 (UTC)
- Yes, we should question and exclude non-MEDRS authors (chemists, according to their affiliations) for a review of primary research in a weak, low-impact journal (1.8 IF). The full article here is mainly about the chemistry and microbial composition of kombucha, with the authors stepping away from their areas of expertise to comment on supposed biological activities which are clearly weak or absent from the evidence shown in Table 3. To cherry-pick this out and discuss it in the encyclopedia article is misleading to users and violates MEDASSESS (bottom of pyramid for evidence, so earns its exclusion) and MEDANIMAL: "The level of support for a hypothesis should be evident to a reader"; it's not. Better to wait for preliminary human research. --Zefr (talk) 19:43, 12 June 2018 (UTC)
- We usually question and usually exclude non-MEDRS sources, but the source is a 2018 review and meets WP:MEDRS.

- I concur with QuackGuru: the source and content meets Wikipedia standards so there appears to be no reason why the paragraph should not be published.

Comments on alternative proposal
I tried a compromise. It is much shorter than the original proposal. QuackGuru (talk) 16:41, 15 June 2018 (UTC)
The alternative Proposal: "The purported health benefits resulting from its biological activities have not been demonstrated in humans." The current wording is shorter. See "the purported health benefits have not been demonstrated in humans". It is missing the part about the biological activities. The current wording in the article is slightly different than the proposal. QuackGuru (talk) 15:14, 23 July 2018 (UTC)
I spoke too soon. The article was updated to invoke consensus. QuackGuru (talk) 15:29, 23 July 2018 (UTC)

- Comment/Proposal Have only now received an RFC. I agree with the sentiments of QuackGuru et al, and if the proposed wording is preferred, I support it. However, it seems to me that there are two concepts worth mentioning. I propose including both and rewording for clarity and ease of reading:
"Studies in recent decades have shown neither any health benefits, nor any biological properties of special value."
Append preferred citations according to taste. We do not really need to speak of the understanding or otherwise of the biological properties, whether beneficial or otherwise, being understood or not. The negative agnostic tone seems to me non-misleading and encyclopaedic. (Feel welcome to replace words like "shown" with "revealed" or "demonstrated", according to the desired tone and register.
"Studies in recent decades have failed to show either any health benefits, or any biological properties of special value."
might be slightly less ambiguous, but more cumbersome; again, take your pick.) JonRichfield (talk) 05:25, 24 June 2018 (UTC)- Biological activities and biological properties are different. The researchers are examining its properties as well as examining the biological activities of each of those properties. For the biological activities it has not been shown to be effective for humans. I recently added similar content. I added "Its biological activities have not been demonstrated in humans for their purported health benefits."[7]. See Talk:Kombucha#Alternative proposal for the other RfC. As long as the word "activities" remains you or anyone can adjust the wording. QuackGuru (talk) 05:36, 24 June 2018 (UTC)
- Disagree with initial "there is a lack of understanding" wording. That wording implies that the purported activities exist, but are merely not understood. We need wording that clearly indicates that we have no scientific evidence for the existence of these activities. —David Eppstein (talk) 22:20, 12 July 2018 (UTC)
- I changed it to "There is a lack of research regarding its biological properties.[24]" There is another proposal that shows there is no solid evidence for the biological activities in humans. See "The purported health benefits resulting from its biological activities have not been demonstrated in humans.[1]" See Talk:Kombucha#RfC on adding current research status and see Talk:Kombucha#Alternative proposal.

Content requires a rewrite

- In Ernst under the heading Study selection it states Study designs of evaluations included in the review. Under that section it states "Post-marketing surveillance studies, clinical trials, case reports, spontaneous reporting schemes and pre-clinical studies were eligible for inclusion in the review."[10] There is no mention of "absence of human randomized controlled trials".

Sourced content replaced with vague or unclear wording
See "Kombucha tea has been claimed by kombucha drinkers all over the world to have many beneficial effects on human health. However, most of the benefits were studied in experimental models only and there is a lack of scientific evidence based on human models."[1][11] Also see "There is still a dispute over the beneficial effects of kombucha drink. There has been no evidence published to date on the biological activities of kombucha in human trials. All the biological activities have been investigated using animal experimental models."[1][12]
Previous wording: "People drink it for its many putative beneficial effects, but most of the benefits were merely experimental studies and there is little scientific evidence based on human studies.[1] There have not been any human trials conducted to confirm any curative claims associated with the consumption of kombucha tea."
New wording: "People drink it for its supposed beneficial effects, but most of the benefits are assumed from the results of low-quality preliminary studies".[1][13]QuackGuru (talk) 17:33, 1 July 2018 (UTC)
- Given the sentences that precede and follow this new wording, this sentence is redundant. I say omit it altogether, and if the reference given is valuable, add it to the reference of the sentence that follows. JonRichfield (talk) 13:06, 2 July 2018 (UTC)

No further comments were made to address the problems. I edited the article to improve the wording and to clarify the content. QuackGuru (talk) 12:19, 13 July 2018 (UTC)
New wording was:
"People drink it for its many purported beneficial effects, but the majority of the benefits were merely experimental studies and there is little scientific evidence based on human studies.[1] There have not been any human trials conducted regarding its biological activities,[1] and the purported health benefits resulting from its biological activities have not been demonstrated in humans.[9] So far, there have been animal studies that looked into its biological activities.[1] "
Last year back in December 2017 it stated:
"People drink it for its many putative beneficial effects, but most of the benefits were merely experimental studies and there is little scientific evidence based on human studies.[1] There have not been any human trials conducted to confirm any curative claims associated with the consumption of kombucha tea.[1] There is no high-quality evidence of beneficial effects from consuming kombucha.[4]"[14]
Too much content is being deleted against consensus. Sourced content was previously replaced with misleading content. "People drink it for its supposed beneficial effects"[15] is misleading. The content "Based on the absence of human randomized controlled trials" failed verification[16] "Although people drink kombucha for such supposed health benefits" is also vague or unclear. The source stated it was "many".[17] The source uses a capital "K". QuackGuru (talk) 19:55, 13 July 2018 (UTC)
Current research

Several in vitro studies have been done for kombucha which were in 1998, 2000, 2011, 2012, 2014, 2016, and 2017 as well as several researchers have done in vivo studies using rats from 2013 to 2015 for kombucha in the areas of diabetes, electromagnetic radiation, and liver and kidney toxicities due to diets high in cholesterol.[1]

pH
The figure of 2.5 seems remarkably low, although it's from a reputable source.
Commercial websites give higher values - are there any independent sources (academic researchers or food analysis organisations) that find the pH to be higher as well?
Best regards Notreallydavid (talk) 13:56, 21 August 2018 (UTC)

Changes to lede
The previous wording was far better. The new wording greatly weakened the undisputed content. There may also be a verification problem. The part "..ranging from promoting gut health through probiotics to curing asthma..."[19] may not be supported by the source presented. The part "isolated adverse events may be attributable to it"[20] is duplication of the serious adverse effects previously mentioned. See category Health drinks for other drinks being promoted beyond belief. QuackGuru (talk) 01:35, 4 September 2018 (UTC)
- People that would drink kombucha for health reasons would primarily do it for the probiotics. The fact it was not even mentioned in the lede was really strange and the fact that it is not really delved into shows that no one wanted to do the research. Bod (talk) 02:51, 4 September 2018 (UTC)
- "People that would drink kombucha for health reasons would primarily do it for the probiotics," according to who? The only benefit is for those selling it according to the 2003 review.
- Even more problems have been introduced in the article. For example, see "Numerous claims have been made regarding the health benefits from the consumption of kombucha, ranging from promoting gut health through probiotics to curing asthma, but there is no scientific evidence to support these views.[7][2]" Sources 7 and 2 were combined to come to a new conclusion.

Continued changes
See "Drinking kombucha as a therapeutic food is not recommended because its benefits are unclear and do not outweigh the potential harms."[21]
See "The potential harms of drinking kombucha outweigh the possible benefits, so its use as a therapeutic food is not recommended."[22]
The previous wording is closer to the source. The part "possible benefits" contradicts the source. QuackGuru (talk) 11:40, 5 September 2018 (UTC)
- Agreed that "possible benefits" does not capture the sense of the source. But more, the source does not say "Drinking kombucha as a therapeutic food is not recommended" - it says the known harms outweigh the benefits period - not just when considered as a "therapeutic food". Alexbrn (talk) 11:53, 5 September 2018 (UTC)
- See "The potential harms of drinking kombucha outweigh the unclear benefits, therefore its use as a therapeutic food is not recommended."
- What about this wording? The part "unclear benefits" is supported by the source. QuackGuru (talk) 12:15, 5 September 2018 (UTC)

Yes. In fact, I wonder if we could do better still. The paper itself concludes thus:
Unconventional remedies such as Kombucha are increasingly popular, not least because they are supported by frequent and favourable media coverage [15]. For many of these treatments there is little clinical evidence supporting efficacy. Kombucha is an extreme example in several ways: there is no convincingly positive clinical evidence at all; the claims for it are as far reaching as they are implausible; the potential for harm seems considerable. In such extreme cases, healthcare professionals should discourage consumers from using (and paying for) remedies that only seem to benefit those who sell them.
In conclusion, none of the numerous health claims for Kombucha is supported by clinical evidence. The consumption of Kombucha tea has been associated with serious adverse events. Its therapeutic use can therefore not be recommended.
We need to be faithfully conveying the sense of this. Alexbrn (talk) 12:46, 5 September 2018 (UTC)
- Yes, we do; and in similarly robust language. Peter coxhead (talk) 14:32, 5 September 2018 (UTC)
Not encyclopedic
Numerous "implausible" claims have been made for health benefits from drinking kombucha. The word "implausible" is not encyclopedic and not needed. Another editor stated "Now "implausible" is not encyclopedic, and should be removed, but this didn't seem to be the reason for your tagging." There is not talk page consensus for this. The previous thread did not include this language. QuackGuru (talk) 00:44, 7 September 2018 (UTC)
- It's a good word for ... implausible things. Per NPOV we should reflect decent sources and if they say the health claims for kombucha are implausible (that it cures AIDS, FFS!) then we do do. Alexbrn (talk) 06:40, 7 September 2018 (UTC)
- If it's an editorial comment, i.e. not in quotes, then it seems to me very clear that "implausible" is not encyclopedic – it's not for Wikipedia to say what is or is not "implausible". The solution is to explicitly quote the source that uses this word; in quotation marks, it's fine. Peter coxhead (talk) 08:54, 7 September 2018 (UTC)
- It is absolutely for Wikipedia to say what is implausible, if it is according to RS. There is no dispute so it should just be WP:ASSERTed. Alexbrn (talk) 09:00, 7 September 2018 (UTC)
- I would prefer something like 'Claims that ... are described as "implausible"[ref]', which makes the point without implying it's an editorial summary. The core point of WP:EDITORIAL is that we should "maintain an impartial tone"; quoting makes it clear that we are not taking on ourselves to say that something is implausible (however much we all agree that it is), whereas the current words read as an editorial judgement. But it's a fine point, which I why I left it. Peter coxhead (talk) 09:18, 7 September 2018 (UTC)
- I think attributing it like that is unnecessary and may even give the false impression it's in dispute, or is just one source's view. The idea that drinking fermented tea can cure HIV/AIDS fails a prior plausibility assessment - there is no disputing that from any sane quarter, either in RS or in real life. Alexbrn (talk) 09:28, 7 September 2018 (UTC)
- The word "implausible" does not maintain a neutral tone. I'd rather remove it all together. QuackGuru (talk) 11:28, 7 September 2018 (UTC)
- Well, that "neutral tone" argument we hear about words like "pseudoscientific" all the time. This wording is neutral alright because it is factual and used by RS. The idea that drinking tea can (e.g.) halt/reverse retroviral disease progression is, literally, implausible: there is no plausible reason to suppose such an effect would follow. I'd be happy to replace it with "ridiculous", "far-fetched" or "preposterous" though. If in doubt ping WP:FT/N and ask if we should call implausible things implausible.

Kombucha Day
TheCalculus As noted, facebook.com and kombuchacenter.com are not considered reliable sources. Furthermore, your facebook link didn't even back up your claim. A kombucha seller stating that they've heard that the mayor is going to announce a kombucha day isn't the same thing as the mayor announcing a kombucha day.

- TheCalculus Thank you for listening to feedback and working to improve the content, but there are still issues. I see no evidence from the Portland mayor's office that they are involved in a Kombucha day. I'm not saying it isn't true, but wikipedia is WP:NOTNEWS, so we can wait over the next few to see what shakes outs. Your well+good citation fails WP:MEDRS for the same reasons that kombuchacenter.com did. I have looked, and aside from the kombuchacenter.com link that also links to the well+good article, I cannot find evidence of Square making such claims. Again, not saying I know the information isn't correct, but the current citations don't prove the claims to the standards of wikipedia. †Basilosauridae❯❯❯Talk 02:44, 9 September 2018 (UTC)
- Basilosauridae Thanks again for your feedback. I agree that a citation directly from the mayor's office is the best source. I'm not sure if their site is where this information can be found, but I will keep checking in the meantime. Not that any of the following necessarily constitutes as a proper source, but this event was reported by numerous local news stations, in addition to affirmations from the mayor's social media account of him making such declarations, as can be seen here: https://twitter.com/WesleighOgle/status/1037326310610108416.
Subjective Claims...
Alexbrn OK, I don't know WHY you keep putting these extremely subjective claims back up on the page. Exactly who says that kombucha is "not recommended for therapeutic use", and why is that OK to put on an objective Wikipedia page? Now, it would be fine to quote somebody saying that, but for you to keep putting these subjective and partially untrue (as a matter of fact, Kombucha DOES have a lot of notable health benefits, which is actually proven here: https://www.healthline.com/nutrition/8-benefits-of-kombucha-tea) claims back on the page (especially without an opinion on a different side of the issue) is simply not acceptable.--Neateditor123 (talk) 18:59, 13 December 2018 (UTC)Neateditor123

- Alexbrn While I do understand your point of view, the thing is, the way the statement was said makes it extremely objective. Again, why would the extremely subjective statement "Kombucha is not recommended for therapeutic use" be on a completely objective Wikipedia page? As I said before, you could just quote somebody making that statement (ex. "According to Dr. Nick, kombucha is not recommended for therapeutic use") and that would be OK, but as that statement currently is, it's not OK for Wikipedia to use. Plus, as it currently is, the page has an extremely negative view towards kombucha and the results of consuming it, which isn't even remotely neutral. Hopefully, we can work out a reasonable solution to these issues.--Neateditor123 (talk) 19:27, 13 December 2018 (UTC)Neateditor123

- Alexbrn Even if those claims are true, they're still way too subjective. Seriously, how is "Kombucha is not recommended for therapeutic use" not a subjective sentence? As I've been saying this entire time, couldn't you at least just quote the person who wrote the sourced article saying that so you know it's just that person's opinion?--Neateditor123 (talk) 19:36, 13 December 2018 (UTC)Neateditor123

Roxy the dog, Alexbrn While I probably shouldn't have kept reverting everyone's changes to my edits, I only did them because Alexbrn said that "there seems [to be] no point [in] continuing this", which lead me to believe that the discussion was over (especially since he didn't revert my edit to the sentence "Kombucha is not recommended for therapeutic use"). Again, as I've been saying the entire time, the page should state that doctors say that kombucha is not recommended for people with poor immune function (to name just one thing), not just state that itself. Also, just because something is sourced perfectly well doesn't mean that Wikipedia's statement about it shouldn't also say who says this.--Neateditor123 (talk) 19:59, 14 December 2018 (UTC)Neateditor123

Purported vs. supposed benefits
@Alexbrn: Not a big issue at all, but doesn't the article say that these claims are not supported by any science (i.e. are false or anecdotal at this point) and that kombucha may even have ill effects? I think "purported" is equally valid to "supposed" and they both have a slight implication that this is a false claim. "Purported" highlights that these claims are being promoted by certain people making "numerous implausible claims" which is also in the lead. —DIYeditor (talk) 20:42, 26 October 2018 (UTC)

Production
From the article:
"Standard Kombucha production procedures include starts with boiling 1L non-chlorinated water and dissolving 50g sugar in the boiling water. Next, 5g of tea leaves are steeped in the hot sugar water for 5 minutes and then tea leaves are discarded. Sweetened tea is cooled to around 20°C and 24g of SCOBY culture is added. This is poured into a sterilized beaker or other glass container along with 0.2L of previously fermented kombucha tea. This will lower the pH. The container is covered with a paper towel or breathable fabric that will not allow insects such as Drosophila fruit flies to contaminate the kombucha. The tea is left to ferment for a period of up to 10 to 14 days at room temperature (18°C to 26°C). A new "daughter" SCOBY will form on the surface of the tea to the diameter of the container. After fermentation is completed, the SCOBY is removed and stored along with a small amount of the newly fermented tea. The remaining kombucha is strained and bottled for a secondary ferment for a few days or stored at a temperature of 4℃.[36]"
Any reason not to remove this per WP:NOTHOWTO? Gråbergs Gråa Sång (talk) 10:20, 22 June 2019 (UTC)

Japanese
I noticed this edit [24] which changed the Japanese spelling, but I'm not sure which is correct. Gråbergs Gråa Sång (talk) 11:26, 16 January 2020 (UTC)
I suspect the edit was made because the article kombu is spelled as such. However, per WP:ROMAJI, we should use modified Hepburn romanization, which never changes the n to m. --Yel D'ohan (talk) 19:43, 25 September 2020 (UTC)
Current origin
Lead:Kombucha is thought to have first originated in Manchuria where the drink is traditional.[3][4]
Body:The exact origins of kombucha are not known, although the most likely place of origin is the Bohai Sea district in China.[4]

Undue weight on adverse health effects
I think some of the claims at the adverse effects are exaggerated and "cherry picked" from certains papers, almost suggesting that the kombucha is a lethal beverage. The "At least one person is known to have died after consuming kombucha, though the drink itself has never been conclusively proven as the cause of death." is outright sensationalist and no research have found direct evidence between kombucha and the cause of death (if I also have numerous underlying health conditions and pass away anytime after drinking Coca-Cola, can we assume that I died because of coke?), therefore I do not think that is fair to put this much emphasis on contamination or possible health hazards. Susceptible, allergic or immunocompromised people may experience adverse effects (just like from any other drink or food if one happens to be allergic), but this entire section implies that the alleged health benefits are close to some kind of hoax, whereas people can die just by consuming kombucha. Adlersson (talk) 11:13, 19 June 2021 (UTC)
- @Adlersson: All claims appear to be reliably sourced, although from ancient sources, with the 2019 review concluding that 4oz daily is not dangerous and also describing the circumstances under which it can be dangerous. It seems to me that if the 2019 systematic review is the most complete review on the risks of kombucha, it should at the very least be at the top of the section rather than the bottom as almost an afterthought. I agree that the inclusion of single dubious cases is probably POV and unscientific, but I am unsure where Wikipedia consensus stands on this issue. I believe the least controversial change will be to move the most recent, most complete findings to the top of the section. MarshallKe (talk) 19:40, 2 October 2021 (UTC)
- I added Kombucha is not considered harmful if about 4 oz (120 mL) per day is consumed by healthy individuals. However, it has been implicated, but not necessarily confirmed, in a number of case reports of severe adverse effects., and @Roxy the dog: reverted it with the comment "not in source". I will directly quote the source below. Also, this statement is still in the article, so if you want to remove it, you'll have to remove it from the other place.

- What is your reasoning? The source is as far as I can tell, the most recent and complete systematic review on the topic, and my edit is an accurate summary of its findings on side effects. I believe the most recent, complete information belongs at the top of the section. I will quote the relevant section of the paper.
Kombucha has been implicated (but not necessarily confirmed) in a number of case reports, including hyponatremia [57]; lactic acidosis [58]; toxic hepatitis after consuming kombucha tea daily for two years [59]; a patient newly diagnosed with human immunodeficiency virus who presented with a case of hyperthermia, lactic acidosis, and acute renal failure within 15 hours of ingesting kombucha [60]; anti-Jo1 antibody-positive myositis [61]; symptomatic lead poisoning from brewing kombucha in a ceramic pot [62]; an outbreak of cutaneous anthrax reportedly from applying the kombucha mushroom to the skin as a painkiller [31]; pellagra [63]; an allergic reaction, jaundice, and nausea, vomiting, head and neck pain [64]; metabolic acidosis [26]; hepatotoxicity [32]; and cholestatic hepatitis [65].
Kombucha contains small amounts of alcohol. In a Food and Drug Administration investigation, the alcohol content of samples ranged from 0.7% to 1.3%; no methanol was detected [26]. Kombucha is contraindicated in pregnant women [7] and likely people with significant renal, pulmonary, or liver disease.
Despite these implications, kombucha is not considered harmful if about 4 oz per day is consumed by healthy individuals; potential risks are associated with a low pH brew leaching heavy metals from containers, excessive consumption of highly acidic kombucha, or consumption by individuals with pre-existing health conditions [26], [66]. Proper brewing methods are described in detail [66].- MarshallKe (talk) 23:35, 3 October 2021 (UTC)

Use of the word "kombucha" in English
The earliest date of 1944 can probably be pushed back several years by someone with the patience to search carefully. For example, a 1932 USDA paper describes kombucha under that name, albeit capitalized. — Preceding unsigned comment added by Indanthrene (talk • contribs) 00:10, 17 October 2021 (UTC)
Pop-cult
Hi @QuickPhyxa, and welcome to Wikipedia! You linked a cite with the lyrics of the song [25] (also a bunch of reader-comments, but they don't count), which is what we call a "primary source" around here (not good enough for this purpose), also against one of our many many many (many) rules, WP:COPYLINK: "external Web site is carrying a work in violation of the creator's copyright." WP is really strict about copyright.
Anyway, what can work here is something like this [26], which is used in the pop-cult section at Tardigrade. It is WP:RS, independant of the musician, and it mentions that he put tardigrades in his song. Gråbergs Gråa Sång (talk) 21:35, 22 October 2021 (UTC)

Biological and Chemical edits
More types of bacteria found in Kombucha were added to the biological section as well as Acetobacteracea being 88% of the bacterial community of the SCOBY. Under the chemical section the function of acetic acid bacteria was added to create a better understanding of the increase and decrease of the alcohol concentration of the Kombucha. Reference 29 was added and used to help support these additions. AMMOORE2000 (talk) 18:16, 3 December 2022 (UTC)
Recent article-wide edit
@Ayush3090, hi. I just reverted this edit of yours: Included another brand among others that were added earlier
This edit does a lot things throughout the article. Some looks reasonable, some does not like the the removal of |work=The New York Times |date=24 March 2010 and a couple of cn/what tags. But the WP:ES doesn't fit very well.
Please don't make edits like these, it's very hard for other editors to see what is going on when you do. Stick to one section at a time, and use better WP:ES. Gråbergs Gråa Sång (talk) 08:57, 16 July 2023 (UTC)

@Bon courage: At no point in the mayo citation does it say kombucha is commonly drunk for its health benefits. It says "there isn't enough proof that kombucha tea has the health benefits that some claim." You can't extrapolate like that. It's borderline original research. TlonicChronic (talk) 02:46, 30 December 2023 (UTC)
At no point in the mayo citation does it say kombucha is commonly drunk for it's [sic] health benefits
← Wikipedia never said that, but that it is commonly drunk for its purported health benefits. The source also says "Supporters claim that kombucha tea helps prevent and treat health conditions". Also note there are several sources in the body, which the lede is meant to summarize, discussing the touted 'health benefits' of kombucha. Are you saying that Kombucha supporters might not drink the stuff? If so, that seems like a slight point to start edit-warring over. Bon courage (talk) 02:58, 30 December 2023 (UTC)- You're extrapolating to "commonly" "commonly consumed for its purported health benefits." The first sentence should deal with the definition of kombucha. It's "purported health benefits" by "some" (whom?) have no place in a definition of a drink. It's fermented tea, sold in grocery stores and farmers markets around the world, not a medicine, nor a potion or quack cure. TlonicChronic (talk) 03:04, 30 December 2023 (UTC)
- We have ample sourcing, including peer-reviewed WP:scholarship, covering the health claims made for kombucha. And per WP:PSCI Wikipedia is required to point out the falsity of the claims made, prominently. Your own views about what kombucha is (or is not) are immaterial. In the real world, just plugging kombucha into a search engine pretty quickly shows that the scholarship is correct: kombucha is heavily promoted for its supposed health effects. See for example:[27] Bon courage (talk) 03:13, 30 December 2023 (UTC)
- Dude... come on... it's fermented tea. People say all kinds of stuff about all kinds of food. People make weird claims about fermented food. People make weird claims about tea. People make weird claims about fermented tea. The point still stands. If you want to say kombucha is "commonly consumed for its purported health benefits" you need a link that says... you know... kombucha is commonly consumed for its purported health benefits. Kale is commonly eaten for it's purpoted health benefits. Blueberries too (remember the antioxidant craze where people literally thought blueberries would prevent cancer?) That doesn't mean blueberries are anti-science. Kombucha is fermented tea. Nothing more, nothing less. TlonicChronic (talk) 03:18, 30 December 2023 (UTC)
- Follow the reliable sourcing, such as PMID:12808367 which describes Komucha as a "popular complementary remedy". The view that komucha is "Nothing more, nothing less" than fermented tea appears to be your personal opinion, with no supporting sources. Bon courage (talk) 03:25, 30 December 2023 (UTC)
- You literally just told someone not to use pubmed as a source TlonicChronic (talk) 03:31, 30 December 2023 (UTC)
- PUBMED is a search engine not a source, and the linked source is solid. I note a recent review in a high-quality journal gives us further information on the touted health benefits of kombucha driving adoption now its becoming a thing in the USA. See PMID:30527803. Bon courage (talk) 03:36, 30 December 2023 (UTC)
- You'll notice none of these sources will boldly state something like "commonly consumed for its purported health benefits"? It's speculative. At best it says "This popularity is likely driven by its touted health benefits." Which isn't the same thing. I'm all for fighting pseudo-science. Let's combat the dumb crap said about kombucha. But you're propping up straw men here. Kombucha food, not medicine. I'm not trying to remove the health section. I'm removing the completely load POV that you're pushing in the first sentence. We want people to stop believing in pseudoscience. We aren't trying to stop kombucha sales. There's a difference. TlonicChronic (talk) 03:41, 30 December 2023 (UTC)
- Although it's only recently a big thing in the USA, Kombucha has been used in Asia for centuries as a supposed remedy. The systematic review I just linked found over 300 medical sources on Kombucha. Wikipedia follows sources, not the opinions of editors. As PMID:30527803 asserts: "Kombucha's popularity as a functional food is driven by its purported health benefits". Bon courage (talk) 03:57, 30 December 2023 (UTC)
- It's not an opinion that kombucha is fermented tea. I don't know why you're hung up on this. You can't define tea as pseudo-scientific. You can point out pseudo-scientific uses of tea. TlonicChronic (talk) 04:08, 30 December 2023 (UTC)
