High quality Thai Red Vein Kratom Powder. Made from mature leaves that are finely ground, you can smell the jungles of Thailand upon opening. Red vein gets it's name from the noticeable red "veins" on the backside of the leaf. The effects appear to me more relaxing and less stimulating then from their green vine cousins, but are rumored to be longer lasting. Many people like to mix this product with the green vein variety.
