Consulting with other people, I've heard about Chinese traditional medicine, and possibly Vodoun. I've Googled for various combinations of bone, magic, sorcery, Chinese traditional medicine, tiger bones (because apparently that's what's used in CTM), voodoo, and vodoun. I've found nothing of much use except that, apparently, CTM believes tiger bones and rhino horns can cure almost anything, which pisses off wildlife conservationists. So far I've found nothing connecting Vodoun to bones, except for Hollywood hype.
Any info on the use of bones in various religions/mythologies would be appreciated, preferably with info about how and why they do what they do with bones.
Edit: I've gotten a lot of suggestions for using bones as divination tools. While I appreciate the suggestions, I'm looking less for divination. I'm not liking for belief systems that use bones to figure out what's going to happen, but that use bones to make things happen, if that makes sense.
