Unfortunately, I'm not too certain whether the article is well researched. Here's an example:
Another large study enrolled 570 participants to see if acupuncture provided pain relief and improved function for people with osteoarthritis of the knee. In 2004, it reported positive results. Dr. Brian M. Berman, the study’s director and a professor of medicine at the University of Maryland, said the inquiry “establishes that acupuncture is an effective complement to conventional arthritis treatment.”True, studies have shown that acupuncture is effective in relieving some sorts of pain. However, it's important to note that research has shown that sham accupuncture (a needle placed anywhere in the body) is as effective as needles placed along mapped "meridians" in treating pain of migraine headaches. This implies that the effectiveness of acupuncture is due to the well described placebo effect.
Many scientists (including and ex-director) feel that the $121 million dollars spent at the National Center for Complementary and Alternative Medicine could be put to better use elsewhere.
