It is a well known medicinal plant. The juice of the crushed plant is ingested as a treatment for stomach-ache and is also used against migraine. Phytochemical investigation on the ethanol extract of the leaves of this plant resulted in the isolation of one sesquiterpene and one flavone, namely 3-(3’-acetoxy-2’-hydroxy-2’-methyl butyryl)- cuauhtemone (LTE-7) and 3’,5,6-trihydroxy-3,6-dimethoxyflavone (LTE-8), respectively.enEthanol ExtractThesis
