Leonotis leonurus (L.) R. Br.

Leonotis leonurus (L.) R. Br.. Leonotis leonurus, also known as wild dagga and lion's ear, is a plant species in the mint family Lamiaceae. It is a broadleaf evergreen shrub, native to South Africa, where it is very common, with a wide altitudinal range from 5 m up to 1980 m. It is known to have medicinal and sedating properties. The main psychoactive component of Leonotis leonurus is hypothesized to be either leonurine or a mixture of labdane-type compounds; Leonotis leonurus has been confirmed to contain leonurine according to peer reviewed journal published phytochemical analysis. Like other plants in the mint family, it also contains marrubin. The word "dagga" comes from Afrikaans, and derives in turn from the Khoikhoi "dachab". The word "dagga" has been extended to include the genus Cannabis in Afrikaans and South African English, so the use of "wild" serves to distinguish Leonotis from Cannabis.
