What is kanna?
Kanna (Sceletium tortuosum) is a small succulent native to South Africa, where the San and Khoikhoi peoples have used it for centuries. Traditionally the plant is fermented — a process that shifts its alkaloid profile — then chewed, brewed as a tea, or taken as a snuff to ease stress, lift mood, and promote a sense of social ease.
The active compounds
Kanna's effects are attributed to a family of mesembrine-type alkaloids — chiefly mesembrine, mesembrenone, and mesembrenol. Research describes these compounds as natural serotonin-reuptake inhibitors (SRIs) with additional PDE4-inhibiting activity, a dual action that distinguishes kanna from most other mood-supporting botanicals. The ratio of these alkaloids — and therefore the character of the experience — depends heavily on the plant's fermentation and extraction.
Traditional and modern use
Where traditional preparations relied on whole fermented plant material, modern users typically choose standardized formats for consistency: a measured extract, a fast-acting tincture, convenient gummies, or dried fermented plant for tea. Reported effects are generally described as gentle mood elevation, reduced tension, and improved sociability rather than intoxication.
Safety and responsible use
Because kanna acts on serotonin, it should not be combined with SSRIs, MAOIs, or other serotonergic medications without medical guidance. Kanna products are for adults 21+. Start low, go slow, and consult a healthcare provider if you take medication or have a health condition.

Frequently asked questions
What does kanna do?
Kanna is traditionally used to elevate mood, reduce stress, and promote social ease. Its mesembrine alkaloids are described in research as serotonin-reuptake and PDE4 inhibitors.
Is kanna an adaptogen?
Kanna is often grouped with mood- and stress-supporting botanicals. It works primarily through serotonergic pathways rather than classic HPA-axis modulation, but is commonly used alongside adaptogens for stress resilience.
How is kanna taken?
Common formats are standardized extracts, tinctures, gummies, and dried fermented plant for tea. Standardized extracts give the most consistent dosing.
Is kanna safe to combine with antidepressants?
No — because kanna affects serotonin, it should not be combined with SSRIs, MAOIs, or other serotonergic medications without guidance from a healthcare provider.
