For a culturally self-aware care giver or individual, imposing your idea on others will not be an option, therefore the key to engaging a non complaint patient who has chosen the idea of trusting herbal medicine over a clinically tested one is persuasion: putting it before the patient the merit of using a prescribed,laboratory tested and a certified prescription over a non tested concoction without denigrating or belittling his belief in the traditional medicine he has chosen over the prescribed one.
I believe the answer you are looking for is "case study" A case study is a publication of an experience conducted over an amount of time. It could be based on behavior for each or a group.
