[Source] From 1: Tao Hongjing: There are many kinds of Polygonum, which are eaten by people. There are three types: one is purple Polygonum, which is similar but purple; one is fragrant Polygonum, which is also similar but fragrant, not very spicy and delicious; the other is green Polygonum, which is commonly found in people. Its leaves are round or pointed, and the round ones are better, so this is the one we use.
