Not suggesting this traditional medicine is a religion but that it’s similar to a lot of the dietary restrictions from history. They had some use for the time but perhaps not useful now.
I know more about Chinese traditional medicine and have similar thoughts. Some of it is interesting but lots of it is pseudoscience. Also some of it was practical advice for the time. A lot of it is always about drinking hot water. Perhaps boiled water was cleaner in previous times? But again it’s mostly pseudoscience. If you visit a traditional doctor he feels your wrist for a while and is able to create diagnoses with that along with looking at you and talking.
