There's an awful lot about plant medicines that can't be understood by scientific study under a microscope, yet has been understood and exploited by humans until quite recently in our history. But now that we know about chemicals & such, we're obsessed with them, and can't see past them.
Explaining this to the average Westerner is really difficult. The terms I want to use - spirit, for instance - are so co-opted that what I say won't necessarily be what is heard. So bear in mind that as I write I can only indicate what I mean approximately, and that it can only be fully understood by experience with the plants themselves.
