    This does just seem like normal advertising prattle. 'accumulation of fatigue'? 'regulate principal activities'?

  • @Rory: I don't think we should be complacent about accepting nonsense from advertisers. In any case, this is worse than normal advertising prattle: "Being different from a therapeutic drug, Yomeishu does not exert its efficacy on a part of the body." - elsewhere on the site.

  • I had a quick look at the research; there is some, but it seems to be published in Japanese, which is making it hard to evaluate it. There is the "Central Research Laboratories" owned by Yomeishu Seizo Co." which have published some papers. The direct conflicts of interest for such research makes it difficult to trust.

    I note they recommend 3 doses per day of 20mL of a liqueur which is 14% alcohol - 8.4mL of alcohol is a little more than half a glass of wine. If people don't feel the chill in their fingers quite so much, I'm not that surprised!

No, it doesn't. There is no evidence to support that.

The claims in the question are based on a more than 20 years old study which assessed subjective symptoms:

We administered 20 ml of Yomeishu (YMS) twice a day before meals for 12 weeks to 50 post-operative patients in gynecology and then inquired into their subjective 20 symptoms (sense of fatigue, insomnia, headache and heavy headedness, appetite, stomach-ache, abdominal inflation, vertigo, lumbago, etc.) The YMS group showed a significant improvement on 14 items compared with the control group. On the whole, a great improvement was observed in the YMS group with serious subjective symptoms as well, and there were significant differences for general condition, sense of fatigue, and coldness in extremities.

  • How do you know this is the only source for the claims?
