About the Kratom Plant

Kratom (Mitragyna speciosa) is a tropical tree growing from 15-50 feet tall (5-15 meters) that is native to Thailand and Malaysia. It has broad, oval leaves that taper to points, yellow flowers that grow in clusters, and winged seeds. The primary active chemicals are mitragynine, mitraphylline, and 7-hydroxymitragynine, all found in the leaves. Kratom leaves have been chewed for stimulant, sedative, and euphoric effects by people in Thailand and South Asia for centuries. They can also be smoked, brewed as a tea, or made into an extract.
