It's overly reductionist to assume that all herbal remedies are the result of 1, maybe 2 active ingredients. The incentive for making a pill is less about efficacy and more about patentability. I can't patent camphor, but I can patent a 3% menthol & 3% camphor ointment suspended in a gel base (Fast Freeze).

I don't think it's fair to say the west as a supposed monolith rejects "woo", especially given the popularity of pseudoscience re: vaccines, homeopathy, Reiki, acupuncture, cleanses, etc.

I'm reminded of the great anthropological paper titled Body Ritual Among the Nacirema by Horace Miner: https://www.sfu.ca/~palys/Miner-1956-BodyRitualAmongTheNacir...
