Well, as said I think the placebo effect that comes from acupuncture, like homeopathy, is very valid and can do wonders. I might actually do a post praising the potential powers of placebo at some point because it's really quite fascinating.

As for what is and isn't true and what does and doesn't work, well I'm not a scholar in the matter myself so the nuances will be researched thoroughly for the second part tomorrow or the next day. I'm sue you'll have some good counter-arguments for what I uncover =)
