The finding was that when the body thinks the skin is being damaged, it produces chemicals to repair the damage. This is not a surprise.
What these anti-inflammatory chemicals do for "Fatigue", or Lymphoma, or Herpes is almost certainly nothing or close to it.
The simplest check is lifespan. Did people live for 70+ years when Acupuncture and Herbal Remedies were the common form of treatment? Or is this possible now because of public sanitation, better diet, and "Modern, Western" surgery and drugs?
"Acupuncture's use for certain conditions has been endorsed by the United States National Institutes of Health, the National Health Service of the United Kingdom, the World Health Organization, and the National Center for Complementary and Alternative Medicine." http://en.wikipedia.org/wiki/Acupuncture
did i say it was free or did i say it was less damaging to the liver?
After having spent 1 month in a lab that studies acupuncture for its effects on heart rate, blood pressure and pain, I have found that the results of these studies are mixed. I will not say they are placebo but I also would not say that dramatically efficacious.
Fortunately acupuncture is without much risk and therefore worth trying for most.
