According to traditional medical pharmacology, what kinds of plant medicines are there?

Drugs that use some or all plants for medical purposes can be divided into traditional plant drugs and modern plant drugs. It is customary in the west to call plant medicine natural medicine. The plant extracts produced by modern science and technology are modern plant medicines. Traditional medicine, a kind of herbal tea called red bush tea, is very popular all over the world, partly because it is rich in antioxidants. The scientific name of the red shrub is Aspalathus linearis (Burm.F.) Dahlgren, and the common name is rooibos, which is a flowering shrub unique to South Africa and used to make light-tasting tea. This kind of tea contains no caffeine, almost no tannin and rich antioxidants.
