About

Mesembryanthemum tortuosum, often referred to by its synonym Sceletium tortuosum, is a succulent plant in the family Aizoaceae, native to the Cape Provinces of South Africa. In English, it is commonly known as kanna, or alternatively kougoed, an Afrikaans term meaning 'chewable thing', originally referring to a fermented preparation of the plant that was chewed by the Indigenous Khoisan peoples for its medical and psychoactive effects. The plant contains more than 25 alkaloids, with mesembrine-type alkaloids predominating.
