at this point "important traditional therapies" don't exist. if they were working, these things are tested, standardized or sometimes used as a starting point of something else, at which point they become therapies without adjectives. this is how we got artemether and digoxin. everyone in pharma is looking for new stuff, this is why they're looking for alkaloids in obscure sea sponges and random vines, sometimes it's the entire thing, but more often not. this is also how we got taxol
what are you saying could have been true in 70s, but by now almost all attested traditional therapies were tested already and developed into something new that works and passes all regulatory tests
you can't just throw random bullshit at desperate people and expect everything to work. you can expect them to pay, that's how scams work. also i don't see, in most charitable terms, how restricting scammers is a barrier to organizing
