Considering that Aspirin was basically made from White Willow Bark and penicillin was derived from moldy bread, both used by ‘shamans’ for centuries, it wouldn’t hurt for an enterprising entrepreneur to investigate. If there is anything there, it can be used, if not, debunked so folks aren’t taken.
Frankly, in my not so humble opinion, whatever works for one to get in touch with the Great Spirit is whats right for them.
