Before we talk about Green vein Kratom let us talk a bit about kratom. Kratom is a botanical herb that is sourced from Mitragyna Speciosa. It’s a scientific name for the tree that is found all over the Southeast Asian regions. The warm climatic conditions help this species of tree thrive in the dense forests of the many islands in the region. To be honest, there is nothing too noticeable about the Mitragyna Speciosa, or kratom tree itself. Except that their leaves are of particular importance to the native people as well as millions of people around the world including the US.
