Leaves are chewed to disinfect mouth and throat and are useful in stomatalgia. The flowers are cooling, bitter, astringent, acrid and antipyretic. The juice of the flowers is applied to the eyes for nyctalopia and is used for intermittent fevers. The fruits are sweet, bitter, laxative and alexiteric and are useful in flatulant-colic, anaemia, emaciation and vitiated conditions of tridosa.
