Kanna (Sceletium tortuosum)
Sceletium tortuosum, better known as kanna, was used as a psychedelic by the Hottentots of South Africa. It can be sniffed, chewed or used as tea. The Dutch who arrived in South Africa called it kougoed, which means 'chewing substance'.
Effects of kanna
Sceletium tortuosum relaxes and is socially stimulating. Some users have noted enhanced tactile and sexual response.
Kanna can be used as a snuff, in which case 20 mg is sufficient to produce a substantial effect. You can also chew it with a piece of gum. In that case it's advisable to take a larger amount, for example 100 mg to one gram. You can also make a kanna tea (add honey or another sweetener) or extract the active compound with alcohol.
