Kratom (Mitragyna speciosa) is a tropical evergreen tree native to Southeast Asia. Its leaves have been used traditionally for centuries. This beginner’s guide explains what kratom is, how it is used, and how modern extracts like 7-hydroxymitragynine (7-OH) fit in.
Origin
Kratom grows in Thailand, Indonesia, Malaysia, Myanmar and Papua New Guinea. Different regions produce different alkaloid profiles, which is why some kratom is more relaxing and some more stimulating.
Alkaloids
Kratom leaves contain over 40 alkaloids, with mitragynine and 7-hydroxymitragynine being the most studied.
Traditional use
For centuries, Southeast Asian workers chewed fresh kratom leaves or brewed them into tea. The effects varied by strain, dose and individual.
Modern formats
Today, kratom is sold as raw leaf, powder, capsules, extracts and chewable tablets. 7-OH tablets are the most modern and consistent format.
