Kanna (Sceletium tortuosum) is a succulent herb native to South Africa, traditionally chewed or fermented by the Khoisan people for its mood-enhancing effects. Today, it’s available as powders, capsules, teas, and even vape products—marketed as a natural stress reliever and herbal nootropic.
Modern interest in kanna has grown thanks to its unique ability to uplift mood without the harsh side effects of pharmaceuticals. But what exactly are thekanna effects, and what should first-time users expect?
Kanna acts primarily as aserotonin reuptake inhibitor (SRI), meaning it helps increase serotonin levels in the brain—similar to some antidepressants. It also interacts with thedopamine and opioid systems, contributing to its relaxing and euphoric properties.
Active Compounds Include:
Mesembrine: Main alkaloid, promotes mood enhancement
Mesembrenone & Mesembrenol: Contribute to anxiolytic and mild stimulant effects
Unlike traditional stimulants or depressants, kanna tends to balance energy and calmness—making it unique among herbal supplements.
✅Mood Boost:A sense of mild euphoria, contentment
✅Anxiety Relief:Mental quieting, fewer racing thoughts
✅Mental Clarity:Improved focus, especially at low to moderate doses
✅Social Ease:Feelings of connection, openness in conversation
✅Body Relaxation: Loosening of tension, especially in shoulders and jaw
✅ Tingling or Buzzing Sensation: A light energetic buzz in limbs or face
✅Reduced Pain Perception: Some report relief from tension headaches or soreness

While most people use kanna occasionally, some incorporate it regularly for mood support. Early anecdotal and clinical research suggests the following long-term effects:
✅Improved Emotional Resilience
✅Reduced Symptoms of Mild Depression or Anxiety
✅Better Stress Response and Sleep Quality
⚠️ Tolerance: Daily use may reduce effectiveness. See kanna tolerance tips.
⚠️Interaction Risks — Long-term use with SSRIs or other serotonin-based meds can raise safety concerns (more below)
While kanna has a long history of traditional use—for thirst, fatigue, wound healing, and social rituals—modern research is still catching up. Preliminarystudies suggest kanna may have several biological effects, including:
Antidepressant and anxiolytic (anti-anxiety) properties
Cognitive-enhancing effects, such as improved mental clarity or focus
Anti-inflammatory, antioxidant, and antimicrobial activity
A few early animal and lab studies have identified these potential effects through compounds like mesembrine, which modulates serotonin and other mood-related pathways.
A 2023 systematic review and meta-analysis evaluated kanna’s impact on anxiety and found no conclusive clinical benefit over placebo. While these findings don’t rule out kanna’s effectiveness, they highlight the need for larger, high-quality human trials.
In short:Kanna shows promise for mood support and stress relief, but evidence is still early and mixed.
While kanna is generally well-tolerated, it isn’t side-effect free—especially at high doses or when mixed with certain substances.
Nausea or upset stomach
Headache or dizziness
Fatigue or brain fog (at higher doses)
Irritability during "comedown"
SSRIs or SNRIs (e.g., Prozac, Zoloft)
MAOIs
High-dose 5-HTP or St. John’s Wort
Mixing kanna with otherserotonin-boosting substances increases the risk ofserotonin syndrome, a rare but serious condition.
Mixing with other serotonergic substances increases serotonin syndrome risk. For general safety, see is kanna safe?.
