I've read a decent chunk of that research, but it's often relegated to backwater low-reputation journals focused on alternative medicine and is largely ignored by mainstream science. For an example, see the research on various traditional sleep-inducing drugs.
It also doesn't make its way into mainstream practice among GPs and psychiatrists. As an example, which mainstream practitioner would ever prescribe or recommend curcurmin with piperine for any condition, aside from alternative medicine practitioners? Which psychiatrist would recommend EPA fish oil for depression? I could go on. The research that does exist is largely ignored.
Not in that way, no. Pharma, on the other hand, often looks into various remedies etc. in order to draw from and produce more distilled and controllable substances. Aspirin for example, from 'cook a tree bark and drink the solution' into a pill process. Penicillin.. etc.
