Kratom types are generally divided into three different colors. Red-vein, White-vein or Green-vein. This division is dependent on the color of the stem and vein of the leave. If you look closely at a kratom leaf you will see that the stem and vein have a certain color. This color determines the effect the kratom leaf will have on mind and body. Different color means a different effect and a different chemical composition. The stem and vein will be removed during the grinding process. Therefore It is only the leaf which is supposed to be taken, without the stem and vein.
The Kratom different kratom strains thrive at their best in different conditions and contain various alkaloids which each produce their own effects. Red vein kratom strains are suitable for certain purposes, while green and white kratom strains are more appropriate at other times.
