What is Kanna? Kanna, also known as Sceletium tortuosum, is a succulent plant that has been used for centuries by indigenous people of South Africa for medicinal purposes. It is believed to have mood-boosting and anxiety-relieving effects due to the presence of psychoactive alkaloids such as mesembrine. Kanna can be consumed in various forms, including chewing on dried leaves or stems, making a powder or capsule from the plant material, or brewing it into a tea. The plant has gained popularity in recent years due to its potential therapeutic benefits.
