It really is amazing how little we know about the healing and prophylactic qualities of plants and minerals.  I mean, sure, we do know a lot.<p>But we have such a perverse incentive structure - and I&#x27;m talking about IP here - that makes it more worthwhile to understand something esoteric and bizarre like a difficult-to-isolate chemical compound, unlikely to have been encountered very often in the history of human evolution, while it&#x27;s difficult to find motivation to do a simple study like this one.
