LOL, that is not peer reviewed studies but just anecdotal claims.
As of 2021 many thousands of papers had been published on the efficacy of acupuncture for the treatment of various adult health conditions, but there was no robust evidence it was beneficial for anything, other than evidence for shoulder pain and fibromyalgia - and none of the evidence that it would be superior to traditional medicine. For
Science-Based Medicine,
Steven Novella wrote that the overall pattern of evidence was reminiscent of that for homeopathy, compatible with the hypothesis that most, if not all, benefits were due to the placebo effect, and strongly suggestive that acupuncture had no beneficial therapeutic effects at all.
Of course all acupuncture practicing quacks will tell you how effective it is - yet that is how placebo works! Same like homeopathy - complete quackery with zero effect yet millions of dollars earned from naive people believing in that nonsense.
