Kanna

Sceletium tortuosum

Kanna has one of the oldest recorded histories of any plant in southern Africa. The Khoi and San peoples chewed or smoked a fermented preparation of the plant known as kougoed, meaning something close to "chewing stuff," long before Dutch colonists first wrote about it in the 1660s. It was carried on long treks, shared in social gatherings, and passed between travelers as a way to ease weariness, lift spirits, and quiet a restless mind. Because the plant contains naturally occurring alkaloids that act on the nervous system, this history sits at the crossroads of tradition, culture, and genuine pharmacology, not casual folklore.

Safety.

Sceletium tortuosum is a psychoactive plant. It contains mesembrine and related alkaloids that influence serotonin activity in the brain, and traditional preparations were valued precisely for their mood-altering, sometimes euphoric effects. Because of this mechanism, kanna carries a real risk of dangerous interaction with SSRIs, SNRIs, MAOIs, and other serotonergic medications, potentially leading to serotonin syndrome. It is not appropriate for use during pregnancy or breastfeeding, for children, or in combination with alcohol or other psychoactive substances, and its safety has not been established through rigorous clinical study. This entry is offered for historical, cultural, and botanical interest only and does not describe a dose or method of ingestion. Anyone considering it for any reason should speak with a qualified healthcare provider first, particularly given the interaction risks with common psychiatric medications.
