Ive heard of people who dedicate their studies to this. Also Ive an anthropologist friend who spent time living in a developing country studying how people culture blended their traditional vs modern medicine usage.

IMO a real boon for medicine will be increasing sophisticated personal monitoring and the data this makes accessible to the world when shared. If sure we'll see some amazing cause/effect relationships from all sort of areas being identified in coming years .
