Due to different growth regions and breeding, kratom has evolved into a variety of different strains, which can be very different in effects. There are three primary effect categories one can divide strains into: stimulating, sedating and moderate.
It should be noted that every plant within a strain can vary, so in no way are these analyses set in stone; rather we have taken a more statistical approach, based upon large amounts of individual user experience reports to provide a guide to the general strain characteristics.
