Myrrh (Commiphora molmol) is a small tree (low bush) mainly cultivated for resin or gum, which is collected from the secretions produced by incisions into the plant's bark.
Myrrh yields volatile oil, called myrrhol, which contains curninic aldehyde, eugenol, m-cresol, pinene, limonene, dipentene, and two sesquiterpenes. It is used as an anti-microbial, astringent, carminative, anti-catarrhal, expectorant, vulnery, and tonic.
