Xuan Fu Hua is used in Chinese herbalism as a mildly warming expectorant remedy and it is especially suitable where phlegm has accumulated in the chest. It has been used as an adulterant of arnica (Arnica montana). The flowers are more commonly used, but the leaves are also used, generally for less serious conditions. The leaf is discutient and vulnerary. The flowers are alterative, antibacterial, carminative, cholagogue, deobstruent, depurative, diuretic, expectorant, laxative, nervine, stomachic, tonic and vulnerary. They are used internally in the treatment of bronchial complaints with profuse phlegm, nausea and vomiting, hiccups and flatulence. The flowers have an antibacterial action, but this can be destroyed by proteins in the body. The plant is harvested when in flower and can be dried for later use. The root is discutient, resolvent and vulnerary. The plant has been mentioned as a possible treatment for cancer of the oesophagus.

Cholagogue: Increases the flow of bile and its discharge from the body.
