In Indo-China and China, the aerial parts are used internally as a diuretic, externally on skin infections, like boils and swellings, also caused by poisonous insects and animals. The root is considered depurative, antirheumatic and antisyphilitic. In Thailand, the whole plant is used in alcoholic macerates as a lung tonic, for tuberculosis, asthma and treatment of bloody vomiting. In China, a strong decoction is taken as a diuretic and cathartic; it can stimulate respiration, lower the blood pressure, stop bleeding and reduce swellings.
