Kratom is a herbal substance derived from the leaves of the Mitragyna speciosa tree, a tropical plant native to Southeast Asia. It contains active compounds like mitragynine and 7-hydroxymitragynine (7-OH), which interact with the brain's opioid receptors. While it is often marketed as a natural remedy for energy, pain relief, or anxiety, health agencies warn that it carries significant risks of addiction, dependence, liver damage, and overdose.

- Low Doses (Stimulant): It acts similarly to caffeine, causing increased alertness, physical energy, and talkativeness.
- High Doses (Sedative/Opioid-like): It acts as an atypical opioid, leading to sedation, pain relief, and reduced anxiety. [1, 2, 3]
- Dependence and Addiction: Regular use over just a few weeks can cause the body to develop a physical dependence. Stopping use triggers opioid-like withdrawal symptoms, including severe anxiety, nausea, sweating, and muscle aches. [1, 2]
- Common Side Effects: Nausea, vomiting, dry mouth, constipation, and loss of appetite. [1]
- Severe Side Effects: Liver toxicity, high blood pressure, seizures, hallucinations, psychosis, and respiratory depression. [1, 2, 3]
- Lack of Regulation: Because kratom is not federally regulated or approved by the FDA as a drug or dietary supplement, there are no strict standards for purity. Commercial products are frequently contaminated with heavy metals or Salmonella, or spiked with highly potent, synthetically elevated levels of 7-OH. [1, 2, 3, 4]
