Kanna (Sceletium tortuosum) is a succulent plant traditionally used in South Africa that contains mesembrine alkaloids which act as serotonin reuptake inhibitors (SRIs) and PDE4 inhibitors. It is primarily used for mood enhancement, anxiety reduction, and stress relief, with effects typically described as promoting a sense of well-being and mental calmness without sedation.
