Voodoo and Haitian Science

Who would've known that Haitian Zombie science may actually have a basis in reality?

Haitian accounts write of men who went blue during death, were buried, and were 'resurrected' by a black-magician 12 hours later, and turned in to slaves. These were justifiably dismissed by Western Science as mumbo-jumbo.
It turns out, though, that there is a clinical state which scientists can now induce (using a Haitian root) in which the patient appears to be completely dead (but is not). Their hearts are actually beating though, just extremely infrequently, but enough. Giving them a psychoactive drug even two days later can sometimes "restore them" to life. Such a drug mashes parts of their brain, bringing them in to an obedient, trance-like state, during which they can then be turned in to slaves...similar to the phenomenon of hypnotism. Haitians wrote of another bush which could be used, which contains exactly this psychoactive drug.

Another group of scientists examined a claim of acupuncture, namely that a needle in a certain area of the (thigh, I think) can force a baby to re-orient itself within the womb so that it comes out head-first. In a trial of 1000 cases, in 70% of the cases, such a procedure worked. What I'd be interested to know, is how was such an "energy point" discovered. The methodology which might give rise to such a discovery is completely unknown to me.
Anyway, I take such things with a grain of salt, but the possibility of zombie slaves is too cool to ignore.
