I can't think of any of those from recent history. Medicine has gotten pretty good. Exceptions may be in mental health. Somebody else mentioned psychedelic drugs, which might be FDA-approved for some conditions soon, but all official medical sources currently treat them as extremely dangerous. However, I do think cherry-picking the effective treatments from naturopathy and TCM and turning them into mainstream medicine is similar in spirit to cherry-picking the successful approaches from 80s and 90s AI research and turning them into "just algorithms". But there are a lot more successful old-school AI techniques than there are effective alternative medicine treatments.
