Mitragyna Hirsuta (Latin), also nicknamed Kra Thum Khok by the Asian population, is a tree belonging to the same genus as the popular Mitragyna speciosa, also known as Kratom. M. Hirsuta is similar to this family member in many aspects - appearance, effects, and also the areas of its occurrence.
The tree became popular especially at the time of Kratom's ban in Thailand in 1943 when locals were looking for a legal alternative. The favorite method of application was to chew fresh leaves in the mouth, the dried leaves were then ground into a powder and used in the form of tea.
The main alkaloid here is mitraphylline, which has very similar properties to the mitragynine alkaloids found in Kratom.
According to the legislation of the Czech Republic, Mitragyna Hirsuta is not an approved nutritional supplement or food and is therefore sold only for collectible purposes.
