The term Kratom refers to the Mitragyna speciosa tree, but also mainly to this tree’s leaves when used as a psychoactive or medicine, and their derived products such as crude extracts.

The most common acceptance is that Kratom refers specifically to Mitragyna speciosa.

Yet due to regional (nature of the area where Kratom is grown) and seasonal
(time of the year when the leaves are picked) variations and preparations, different “types” of Mitragyna speciosa Kratom can be distinguished.
