For hundreds of years the Hottentots used Sceletium tortuosum as a
psychedelic called Kanna or Channa (not Cannabis). The earliest written
records of the use of Sceletium date back to 1662 and 1685.

The Dutch during the arrival in Africa called it "Kougoed" (kauwgoed)
which literally means,"chew(able) things/goodies" or"something to

The active constituents of Sceletium tortuosum are alkaloids, including
