Kanna, or Sceletium tortuosum is a small groundcover plant
native to Southern Africa, historically eaten or chewed, or used as a snuff producing alertness which gently fades into relaxation. A tea made from Sceletium is sometimes used to wean alcoholics off alcohol.
Although the plant has been used for thousands of years in
Africa (Hottentots of Southern Africa used Sceletium tortuosum as a mood enhancer, relaxant and empathogen), it is only now being sought by the West for its remarkable capacities
to uplift the mood and increase energy levels and concentration spans. Kanna
may also be used to relieve symptoms of depression, stress and tension, similar
in function to the more well-known herb St John’s Wort. This herb may also improve cognitive function,
reduce high blood pressure and be helpful in cases of post-traumatic stress
disorder, social phobia and general irritability.
