„Wormwood leaves are gathered on a warm dry day in spring and summer when the plant is in flower and dried in the shade. In traditional Chinese medicine, they are considered to have bitter, pungent and warm properties and to be associated with the liver, spleen and kidney meridians. The leaves are used as an antiseptic, expectorant, febrifuge and styptic… It is a common flavoring and colorant in the Chinese dish qīng tuán (青团).“ https://en.wikipedia.org/wiki/Artemisia_argyi
