Mitragyna Javanica (Kra Thum Na) is a little tree species that origins in the southeast of Asia. When consumed, the Mitragyna Javanica could cause euphoric, stimulating and calming effects. These effects are similar to those of the related Mitragyna Hirsuta and Mitragyna Speciosa (Kratom) trees. The Javanica effects are milder though, that’s why It is greatly suited for beginners. For the best results, we recommend making tea out of the herbs.
