The Kneeling angelica (Angelica genuflexa) belongs to Apiaceae (the Carrot family). It is a perennial herb that is distributed from Chubu region of Honshu northward to Hokkaido in Japan, as well as the Korean Peninsula, China, Siberia, and northwestern North America. It grows in moist mountainous areas and is 60 to 150 cm tall. The leaves are 1 to 2 times triternate pinnately compound, and the narrowly ovate leaflets have irregular serrations. From July to September, compound umbels emerge from the stem tops and leaf axils and produce white flowers. The tips of the petals are bent inward, and the stamens, which are longer than the petals, protrude. In Chinese, it is called "毛珠当帰" (mao zhu dang gui).
