In the last few years there has been an explosion in the use of an herb known as kratom here in the U.S. Kratom comes from a tree common to South East Asia where it has been traditionally used for centuries. Mitragyna speciosa comes from the same family of plants as coffee (Rubiaceae) and has been commonly used as a stimulant (in low doses), a sedative (in high doses), an analgesic, for its euphoric qualities, to reduce dependence on opioids, for increased concentration and to improve mood and wellbeing.
