Kratom usually looks like a large tropical tree with broad green leaves in Southeast Asia, but the kratom you are most likely to see is dried green-brown powder, loose leaf material, tea, liquid extract, or capsules. The botanical name is Mitragyna speciosa, and the most useful way to identify a product is to read its label for that name, its format, and whether it is leaf powder or a more concentrated preparation.
The National Institute on Drug Abuse explains that kratom products are commonly swallowed as powder or capsules, mixed into food or drinks, brewed as tea, or sold as liquid extract. The form tells you what you are looking at; it does not by itself tell you how strong the product is.
What does the kratom plant look like?
Kratom is a tropical tree in the coffee family that is native to Southeast Asia. Its leaves are the part used to make most kratom products. A botanical guide describes the leaf as dark green, glossy, oval-shaped, and pointed at the end, typically about 4 to 8 inches long; it also describes a full tree as having a broad, leafy canopy, spreading branches, small yellowish flower clusters, and small round fruit.
Outside its native growing regions, you are far more likely to encounter processed leaf than a live tree. For background on where the plant is grown, see Southeast Asia production.
What does kratom look like after it is prepared?
| Format | What you may see | What to check |
|---|---|---|
| Whole or crushed leaf | Dried leaf pieces | Look for Mitragyna speciosa on the label. |
| Powder | Finely ground plant material, often green to green-brown | Check whether the package identifies plain leaf powder or an extract. |
| Tea or drink | Powder mixed into a drink or brewed leaves | Read the full ingredient list, not just the front label. |
| Capsules or pills | Ordinary-looking capsules filled with powder; some products are also sold as tablets | Check the ingredient panel and the amount per serving. |
| Liquid extract | A bottled liquid preparation | Confirm the stated ingredients and concentration before deciding. |
A capsule does not have one standard color, size, or shape. It is simply a delivery format for the material inside. The practical question is what the package says it contains. Our quality guide explains the label details worth comparing, and lab-tested kratom explains why a current product-specific result matters when you are checking a batch.
Is kratom like an opioid?
Kratom is a plant, not an opiate such as morphine or codeine. Its two best-studied compounds, mitragynine and 7-hydroxymitragynine (7-OH), interact with mu-opioid receptors, which helps explain why people describe some effects as opioid-like. The National Center for Complementary and Integrative Health says people have reported both stimulant-like effects, including increased energy and alertness, and opioid- or sedative-like effects, including relaxation and confusion.
That overlap is real, but it is not a reason to treat kratom and prescription opioids as the same thing. NIDA says the effects can vary with potency, formulation, how it is used, other substances, a person’s health, and prior experience.
What kind of kratom can make you feel high?
Some people use kratom for noticeable psychoactive effects, but there is no simple leaf color, capsule color, or product format that reliably answers this question. The FDA says its researchers have not yet completed a well-designed human abuse-potential study showing whether kratom, mitragynine, or 7-OH produces rewarding effects that lead someone to seek a “high.”
What research does show is that products can differ substantially. Natural kratom leaf contains 7-OH as a minor alkaloid, while the FDA notes that 7-OH has much greater mu-opioid receptor potency than mitragynine. If a package identifies an extract or lists 7-OH, read the full label carefully rather than assuming it is comparable with plain leaf powder.
Does kratom change the way you look or make you age?
Research has not tied kratom to a specific appearance change or an aging effect. NIDA says long-term health effects are not well understood, so a change in appearance is not a useful way to judge a product, its quality, or its effect on you.
If you are comparing material in front of you, focus on the package, the botanical name, the ingredient list, and a product-specific lab result instead of trying to identify it by how someone looks.
What is kratom called on the street?
The clearest names to look for on a product label are “kratom” and Mitragyna speciosa. Those are the names used by U.S. health agencies. If a product uses unfamiliar slang instead of plainly identifying its ingredients, ask the seller for the complete label and batch documentation before ordering.
Will kratom show up on a drug test?
Kratom is not typically included on standard employer drug panels, but specialized testing can look for kratom-related compounds. It also is not the same as an opiate result on a standard panel. If testing matters for work, sports, treatment, or another program, ask what the panel specifically includes before you use any kratom product; do not rely on the package or a general screening assumption.
What organs can kratom affect?
Research is still developing, but the effects and case reports described by NIDA give you a practical map of the body systems involved.
| Body system | What has been reported |
|---|---|
| Brain and nervous system | Stimulant-like effects, drowsiness, confusion, tremors, and seizures in rare serious reports. |
| Heart and circulation | Rapid heart rate has been reported; case reports also include high blood pressure. |
| Lungs and breathing | Slow breathing has appeared in serious case reports, particularly where other substances may be involved. |
| Digestive system | Nausea, vomiting, and constipation are among reported effects. |
| Liver | Case reports include liver problems; NIDA says regular long-term use in large amounts may be associated with serious liver problems in a small minority of people. |
The FDA’s kratom guidance also warns about liver toxicity, seizures, and substance-use disorder, and it notes that some products have contained Salmonella or concerning levels of heavy metals. Avoid combining kratom with other drugs or alcohol, and speak with a clinician before making any decision involving a medication or a health condition.
What does the research settle—and what should you check?
Research supports the basic identification: kratom comes from Mitragyna speciosa leaves, and mitragynine and 7-OH are key compounds researchers are studying. It also supports the fact that people report both stimulant-like and opioid-like effects. The short- and long-term health picture, drug interactions, and the effects of different product formulations are still active research questions.
The FDA says kratom is not lawfully marketed in the United States as a drug product, dietary supplement, or conventional food additive, and state rules can differ. Check your state health or law-enforcement agency for the rule where you live.
Before you order or use a kratom product
- Confirm that the label identifies Mitragyna speciosa and clearly states whether it is powder, capsule, tea, liquid, extract, or another preparation.
- Check the full ingredient panel and ask for the batch-specific lab result.
- Check your state and local rule, since kratom rules vary by location.
- Ask the testing program what its panel includes if a drug-screen result could affect you.
- If you take medication or have a health condition, bring the exact product label to a clinician before deciding.
