Kanna (Sceletium Tortuosum) is a fairly easy-to-grow groundcover succulent plant with leaves in pairs and small white, yellow, or pink flowers that are thin and threadlike. Herb Stomp receives its pure, organic Kanna directly from a South African farm dedicated to the growth of Kanna and similar products. Kanna is also called Canna, Kauwgoed, or Kougoed, the latter of which literally translates to “chewable thing.” Herb Stomp offers both a coarse Kanna, which resembles tiny wood shavings, as well as Kanna powder, which may be a pale greenish-tan color. It does not have a strong taste, although some report that it has a flavor like “liquid hay” when consumed orally.
Sceletium Tortuosum has nine alkaloids. The main two are Aptenia and Mesembrine (roughly 1% to 1.5% total). Mesembrine affects serotonin and dopamine receptors in the brain -- the body’s pleasure centers. Scientists believe mesembrine elevates mood but potentially interacts negatively with prescribed antidepressants (see Warnings below). Kanna is not a hallucinogen. The plant is typically harvested in spring or early summer, as alkaloids are at their highest concentration then.

Kanna is native to South Africa, particularly the Northern, Eastern, and Western Cape provinces, where for thousands of years the native Hottentots chewed it for relaxation. According to Dutch writer Groot van der Gros, in order to gather a year’s worth of Kanna, South African hunter-gatherer tribes would embark on journeys of 100 miles or more.
South Africa’s San (hunter-gatherers) and Khoikhoi (pastoralists) nomad tribes are said to have used Sceletium Tortuosum for medicinal purposes and even used the herb as currency at times. The San in particular admired Kanna for its assistance in healing, divination, and communal dancing.
Kanna Historical Use
Traditionally Kanna was used as a quid, chewed, or consumed as a tea. In the 1600s, Dutch colonialists in South Africa chewed both the stem and the root of Kanna after harvesting the plant, fermenting it in airtight containers, and letting it dry in the sun. Dutch colonial administrator Jan van Riebeeck first wrote about Sceletium Tortuosum in 1662 after he landed in Cape Town, although its use likely predates that time.
Kanna has been used in the hopes of reducing anxiety, calming the mind, improving mood, reducing appetite, and stimulating mental acuity. In South Africa, some drink Kanna as a tea to help reduce their alcohol dependence. In rural areas, tiny amounts of Kanna are added to breast milk for colicky babies.

Back in 1928, P.W. Laider wrote about the herb in the South African Journal of Science in an article titled “The magic medicine of the Hottentots.” Laider noted that the Hottentots “chewed and retained [kanna] in the mouth for a while, when their spirits would rise, eyes brighten, and faces take on a jovial air, and they would commence to dance. But if indulged in to excess it robbed them of their senses and they became intoxicated."
Indeed, Sceletium Tortuosum may have some negative side effects. According to pharmacist and botanist R. Maloth, who wrote of Kanna in a 1913 paper titled “The Flora of South Africa," excess kanna use may result in depression, weariness, headaches, and diminished appetite.
Kanna Current Use
In addition to being chewed or drank as a tea tincture by the Hottentot tribesmen, occasionally tribesman smoked, snorted, or placed kanna under the tongue at the dosage of roughly 50mg to 100mg once or twice a day. Sometimes the Hottentot combine it with damiana or wild dagga. Rhodiola and kava, however, are said to be poor combinations for Kanna.
WebMD users have generally positive experiences with Kanna, reporting the following:
- Its use contributed to an overwhelming feeling of calm and relaxation
- It started working almost immediately and boosted mood and libido
- It promoted mental clarity when taken in the afternoon without the caffeine crash of a cup of coffee (or as self-proclaimed medicine hunter Chris Kilham puts it, “If coffee is a pick-me-up, sceletium is a jet ride to mental brilliance”)
- Its use resulted in more happiness and empathy
Ken Johnson of The Root of the Matter claims Kanna is 10 times more effective of an antidepressant than St. John’s Wort (Hypericum), but as always, a physician should be consulted first.
At least one pharmaceutical company has begun to investigate this. HGH Pharmaceuticals, a South African business based in Cape Town, obtained the first “bio-prospecting” license in 2010 to research and develop a Kanna extract.
Kanna has been the subject of limited scientific research. In 2013, researchers from the Netherlands and South Africa published a paper in the journal Neuropsychopharmacology about the effects of Sceletium Tortuosum on the amygdala and its connection to the hypothalamus. The double-blind study examined 16 subjects’ fear and anxiety after taking Zembrin, an extract of Kanna.
The research was successful and, for the first time, conclusively demonstrated that Kanna can effectively calm down the brain’s threat circuitry, lowering anxiety. This confirmed what many have found first-hand: Kanna has potential for use as an antianxiety and/or antidepressant treatment.
A 1996 paper about Kanna was also published in the Journal of Ethnopharmacology, titled “Psychoactive constituents of the genus Sceletium N.E.Br. and other Mesembryanthemaceae: a review." This paper concludes Kanna does not have psychoactive properties but rather acts as a narcotic and anxiolytic (anti-anxiety or anti-panic substance), noting that more research is necessary due to Kanna’s interactions with pharmaceutical antidepressants (see below section).
WARNING! Kanna is believed to act as a Selective Serotonin Re-uptake Inhibitor (SSRI). In combination with common psychiatric medications including other SSRIs (such as Prozac) and MAO Inhibitors, it may cause injury if ingested.
As with most supplements, safety in pregnancy has not been established.
