Answer to Question #229940 in Physics for Andile Lety

Question

Have you ever wondered how traditional healers discover their medicines? And how about western medical doctors? How do they discover their medicines?

Answer 1

Traditional healers discover their medicines by reading old/sacred books on corresponding topics, some are testing it on themselves or even other people.

Western medical doctors use a more scientific approach, although on the whole it looks similar: they read books (but scientific) and conduct experiments (on animals or other people).
