Sumatra is the largest island that falls entirely in Indonesia. Other Indonesian islands like Borneo and New Guinea are split with other counties. That said a Sumatran Kratom is Indonesian through and through. This particular White Vein is a powder ground from younger leaves with the stems and center veins removed.
Our White Vein is known to be very stimulating with an itchy aroma, and less sedative than other strains, however, any strain is sedative at a high concentration.
