Medicinal Actions & Uses

Da ji is classified as a toxic herb in Chinese herbal medicine, and therefore it is prescribed only for relatively serious illnesses. It is taken as a cathartic to purge excess fluid in conditions such as pleurisy and ascites (excess fluid in the abdomen), and for the treatment of kidney problems, especially nephritis. Da ji is applied externally to inflamed sores to reduce swelling.


Research in China indicates that da ji is therapeutically useful in the treatment of ascites and nephritis; however, it produces significant side effects.
