Stemona root can be used both internally or externally. Externally, it can be applied to the skin as a poultice to rid the body of lice and fungi. Internally, it is used to reduce the incidence of both acute and chronic coughs by relaxing the respiratory system and lowering blood pressure. One component of stemona, tuberostemonine, also has been shown to have some pain-relieving properties. There is also evidence that stemona root, when taken in a decoction with alcohol, can prohibit growth of the bacteria that causes tuberculosis.
