It really helps when one doesnt go to only a single and clearly biased source for their information.

In Nursing school they said pretty much what this acredited government site had to say about it, I highly reccomend you do more than just read the intro I posted bellow:
http://nccam.nih.gov/health/acupuncture/

"Acupuncture is among the oldest healing practices in the world. As part of traditional Chinese medicine (TCM), acupuncture aims to restore and maintain health through the stimulation of specific points on the body. In the United States, where practitioners incorporate healing traditions from China, Japan, Korea, and other countries, acupuncture is considered part of complementary and alternative medicine (CAM)."

It isnt even remotely considered snake oil. smh


And as for scientific evidence of humans being hardwired...just open any medical textbook...I would quote straight from all the ones on my bookshelf but that would simply be too much typing.
