Kanna (Sceletium tortuosum), kava, and kratom are three distinct botanicals with different origins, mechanisms, and effects. Kanna is a South African succulent used for mood support and stress relief. Kava is a Pacific Island root associated with calm and sociability. Kratom is a Southeast Asian plant with stimulant and opioid-like properties, and carries a significantly higher risk profile than the other two.
Three plants. Three continents. Three very different experiences—yet kanna, kava, and kratom are frequently lumped together in wellness conversations, often by people who’ve only tried one or none of them. That’s a problem, because confusing these botanicals can lead to mismatched expectations or, worse, uninformed choices about something you’re putting in your body.
This post breaks down each botanical clearly: where it comes from, how it works, what it feels like, and who it’s best suited for. By the end, you’ll have a solid, practical understanding of how kanna, kava, and kratom differ—and which one might (or might not) belong in your wellness routine.
What Is Kanna (Sceletium tortuosum)?
Kanna is a succulent plant native to South Africa, where the San and Khoikhoi peoples have used it for centuries as a mood-lifting, stress-relieving herb. Traditionally, it was chewed, smoked, or used as a snuff—primarily to reduce anxiety, improve mood, and ease the physical and emotional demands of long hunts or difficult conditions.
The plant’s active compounds are a group of alkaloids—most notably mesembrine—that work primarily by inhibiting the reuptake of serotonin, similar in mechanism (though not in potency) to certain antidepressant medications. Some research also suggests that kanna’s alkaloids may inhibit PDE4, an enzyme involved in regulating mood and cognition.
What Does Kanna Feel Like?
Most people describe a sense of calm alertness after taking kanna—less anxious, more present, without feeling sedated or foggy. At lower doses, kanna tends to be subtly mood-brightening and socially smoothing. At higher doses, the effects can feel more pronounced, sometimes including mild euphoria.
Kanna does not produce a “high” in the recreational sense. It’s better described as an emotional edge-softener. That’s part of why it’s found a home in modern wellness supplements targeting stress, low mood, and social anxiety.
Who Is Kanna Best For?
Kanna is a strong candidate for people looking for natural mood support or a gentle daily supplement for anxiety and stress. It’s also a practical option for those who want something with historical and cultural grounding—centuries of traditional use and a growing body of modern research behind it. People who are sensitive to stimulants or wary of substances with stronger pharmacological profiles tend to respond well to kanna.
What Is Kava?
Kava (Piper methysticum) is a root plant native to the Pacific Islands, including Fiji, Vanuatu, and Tonga. For thousands of years, kava has been central to cultural ceremonies, social gatherings, and conflict resolution across Polynesian communities. Today, kava bars have gained popularity in the United States, Australia, and Europe as alcohol-free alternatives for unwinding.
The active compounds in kava are called kavalactones. These interact with the brain’s GABA receptors—the same receptors targeted by alcohol and benzodiazepines—producing a sense of relaxation and mild sedation without significantly impairing cognition at typical doses.
What Does Kava Feel Like?
Kava produces a body-relaxing, mind-calming effect that many people compare to a mild alcoholic drink, minus the impairment. A common early sign is a numbing or tingling sensation in the mouth and lips. As it takes effect, most users feel relaxed, sociable, and at ease—without the heaviness or foggy thinking that comes with alcohol. Higher doses can produce more sedating effects and are sometimes used as a sleep aid.
Who Is Kava Best For?
Kava suits people looking for a social, relaxing experience—something to wind down with after work, enjoy with friends, or use in place of alcohol. It’s also been studied for its potential to ease anxiety, with a 2013 randomized controlled trial published in the Journal of Clinical Psychopharmacology finding kava to be a promising short-term treatment for Generalized Anxiety Disorder.
One caution worth noting: heavy, long-term kava use has been linked to liver toxicity in some cases, though this risk is generally associated with excessive consumption or low-quality extracts rather than moderate, traditional use.
What Is Kratom?
Kratom (Mitragyna speciosa) is a tree in the coffee family, native to Southeast Asia—particularly Thailand, Malaysia, and Indonesia. Its leaves contain active alkaloids, primarily mitragynine and 7-hydroxymitragynine, that bind to opioid receptors in the brain. This is what makes kratom fundamentally different from kanna and kava.
At low doses, kratom acts as a stimulant: users report increased energy, alertness, and talkativeness. At higher doses, it shifts to produce opioid-like effects—pain relief, sedation, and euphoria.
What Does Kratom Feel Like?
The experience varies significantly by dose and strain. Low-dose kratom can feel similar to a strong cup of coffee—energizing and focused. Higher doses produce a more sedating, pain-relieving effect that some people describe as similar to a mild opioid. This dual nature is part of why kratom has been used both recreationally and as a self-managed tool for opioid withdrawal.
Who Is Kratom Best For—and What Are the Risks?
Kratom carries a distinctly higher risk profile than kanna or kava. Because it acts on opioid receptors, kratom has documented potential for dependence, withdrawal symptoms, and addiction. The U.S. Food and Drug Administration (FDA) has flagged kratom as a substance of concern and has not approved it for any medical use. Several U.S. states have banned its sale.
That said, kratom remains legal in many places and continues to be used by people managing chronic pain or opioid dependency—typically without medical supervision, which carries real risks. Kratom is not recommended for casual or curious use without thorough research and, ideally, guidance from a healthcare provider.

How to Choose Between Kanna, Kava, and Kratom
The right choice depends on what you’re looking for—and how much risk you’re comfortable with.
- Choose kanna if your primary goal is mood support, reduced anxiety, or a subtle daily wellness supplement. Kanna has a gentle profile, a long history of traditional use, and growing scientific interest, making it one of the more accessible and low-risk options.
- Choose kava if you’re after a social, relaxing experience—particularly as an alcohol alternative. Stick to traditional preparations and moderate amounts to minimize liver-related risks.
- Approach kratom with caution. Its opioid-like mechanism sets it apart from the other two in a meaningful way. If you’re considering kratom for pain management or opioid withdrawal support, consult a medical professional first.
The Bottom Line on These Three Botanicals
Kanna, kava, and kratom are not interchangeable. They come from different traditions, act on different systems in the body, and carry different risk profiles. Grouping them together simply because they’re “natural” or “herbal” understates those differences considerably.
Of the three, kanna stands out as the most approachable for everyday mood and stress support—backed by traditional use, early-stage research, and a minimal risk of adverse effects. Kava occupies a social niche with a well-established cultural context. Kratom, while potentially useful in specific circumstances, demands the most caution and the most research before use.
Before adding any botanical to your routine, it’s worth speaking with a healthcare provider—especially if you take medication or have existing health conditions.
Frequently Asked Questions
Is kanna the same as kava?
No. Kanna (Sceletium tortuosum) is a South African succulent that works primarily on serotonin pathways. Kava (Piper methysticum) is a Pacific Island root that acts on GABA receptors. They have different origins, different mechanisms, and different effects.
Is kratom safer than kava or kanna?
No. Kratom carries a significantly higher risk profile than either kava or kanna because it binds to opioid receptors in the brain, creating potential for dependence and withdrawal. Kanna and kava are generally considered much lower risk when used responsibly.
Can you take kanna and kava together?
There is limited research on combining kanna and kava. Because both have calming effects, combining them could amplify sedation. It’s advisable to consult a healthcare provider before combining any botanical supplements.
Is kanna legal in the United States?
Yes, kanna is currently legal in the United States and most other countries. It is not a controlled substance and is widely available as a dietary supplement.
How long does it take for kanna to work?
The onset time for kanna depends on the form—sublingual extracts may take effect within 15–30 minutes, while capsules or teas can take 30–60 minutes. Effects typically last 1–3 hours.
Who should avoid kratom?
People with a history of substance use disorder, those taking opioid medications, pregnant individuals, and anyone with liver or kidney conditions should avoid kratom. Given its opioid-receptor activity, kratom is not suitable for casual use without professional guidance.
