Species have been used in traditional medicine, with various parts of the plants used to treat fever, pain, and dysentery. M. paniculata has been used to induce labor. It has been used in Cuba for painful inflammatory conditions. In Myanmar, Murraya species are used to make thanaka, a cosmetic paste that is typically applied onto the face. Chemistry Compounds isolated from Murraya include many types of coumarins and alkaloids. The novel alkaloid yuehchukene was found in M. paniculata, and it has since been isolated from other Murraya. It is found in red-fruited species with larger petals, but not in black-fruited species with smaller petals. Some species also contain the carbazole girinimbine.
