Background

The cattail herba is composed of four traditional Chinese medicines of dandelion, radix isatidis, herba violae and radix scutellariae, and has the effects of clearing heat, detoxicating, resisting inflammation and reducing swelling. Dandelion herb and Chinese medicine name. Aliases herba Violae, grandma, hua Hualang, etc. Perennial herb of Compositae. Bitter, sweet and cold in nature. It is mainly used for treating furuncle, acute mastitis, scrofula, conjunctival congestion, pharyngalgia, pulmonary abscess, appendicitis, jaundice due to damp-heat, stranguria due to heat, etc.

Radix Isatidis is the dry root of Isatis tinctoria L of Brassicaceae.
