I am not sure I buy it. It's one study, with one condition. I have had acupuncture a few times, it's good for some things, not so much for others. It was was a very interesting experience. I became very relaxed when they had all the needles in, which was odd because I was very nervous about becoming a human pin cushion. Placebo effect, maybe, I don't know. I have also heard of a study that proved there was no such thing as the placebo effect.
I would like to see more studies, with different conditions before I decide it's of no possible benefit. I don't think there is any conspiracy though.
