Guill belonging to the family Rutaceae distributed mainly in Khanh Hoa and Ninh Thuan provinces. According to published documents Vietnam had 7 species of the genus Paramignya. P. trimera is a small woody creeping wild tree distributed in areas over 200 meters where has arid climate thin topsoil. It has been widely used in traditional and folk medicine as an herbal plant for treating the liver diseases blood pressure and cancer. Recently many studies have shown that the root of P. trimera contains many alkaloids saponins courmarins and triterpenoids which have effects on acute hepatitis and inhibited some cancer cell lines. In particular extract is so safe for use. Because of the highly effects of the P. trimera root for treating some cancer cell lines the price of this root is very high so its over exploited exhaustion. In addition due to the high ability of cross-pollination and highly frequency mutations combined with the phenomenon of asexual reproduction and polyploidy the phenotype of in nature is very diverse with many similar characteristics with other plants in the genus Paramignya. The existence of such hybrids makes them difficult to distinguish and confusing based on only .
