Kanna

Herb

Sceletium botanical preparations traditionally chewed or otherwise consumed and now sold as extracts for mood and stress claims. Reviews identify extensive phytochemical work but few clinical assessments, limited toxicology, and little bioavailability evidence.

Pharmacokinetic model

A route-level PK model for kanna is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.
