Unani: Jangali Sudaab.Siddha/Tamil: Arvada.Action: Plant—antispasmodic, sudorific. Stimulates the nervous system; commonly used in decoction in convulsions and fever. Also used as a fumigant in infant catarrh.
The plant gave an essential oil which contains chiefly methyl heptyl ketone (while Ruta graveolens contains 8090% methyl nonyl ketone and methyl heptyl ketone in small amounts). Rutin is the most important active principle of the plant, responsible for its anti- inflammatory and tumour-inhibiting effect.
