Kratom is a botanical preparation derived from the leaves of Mitragyna speciosa Korth. The plant belongs to the Rubiaceae family and is indigenous to Southeast Asia. Traditional preparations include chewed leaves and leaf infusions. Kratom has dose-dependent stimulant-like and opioid- or sedative-like reported effects, but human research remains limited, products are not standardized, and kratom has not been approved by the U.S. Food and Drug Administration for any medical use.
Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.
Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Kratom is not a single purified compound and therefore does not have one definitive molecular formula, molecular weight, solubility, half-life, or standardized dose. Reliable onset and pharmacokinetic values depend on the specific preparation and its alkaloid composition. Evidence-backed clinical and pharmacokinetic research remains limited. The U.S. FDA has not approved kratom or kratom-derived products for any medical indication. U.S. regulatory status may vary by jurisdiction and can change over time.

Botanical name: Mitragyna speciosa Korth; Family: Rubiaceae; Principal reported psychoactive alkaloids: mitragynine and 7-hydroxymitragynine; Kratom is a plant material rather than a single chemically defined compound.
Kratom products can differ substantially in alkaloid composition because of variation in plant chemotype, preparation, extraction, and processing. Natural kratom leaf contains many alkaloids, with mitragynine generally described as the predominant constituent and 7-hydroxymitragynine as a minor constituent. Concentrated 7-hydroxymitragynine products should not be assumed to be equivalent to traditional kratom leaf material.
