Red Vein Thai Kratom products all share one common characteristic: they come from trees that have leaves with reddish stems and veins. The color of the stringy central vein is determined by the presence of different chemicals in the tree. Some of these differences may be genetic and based on the species of tree that the leaves are taken from. Several Kratom farmers have states that red veined plants are more resilient and have a higher yield in Southeast Asian climates. However, there are also reports that different colored veins occur in the same tree at different stages in the lifecycle. The red veining may be more common in younger trees that are more vulnerable to attack from insects. Another theory states that the different vein colors emerge throughout the year depending on external conditions like temperature and weather.
In the past, Kratom leaf pickers would separate the leaves based on their vein color because they found that there were consistent differences in the effects that correlated to vein coloration. In general, red vein capsules and powders are seen as being best for relaxation, replacement of pain medications, and as mood enhancers. These distinctions should be viewed as loose characterizations instead of hard and fast rules for how Red Vein Kratom will affect you; slight changes in method of consumption, product potency, individual biochemistry and metabolism can all alter your experience when taking this herb. It is also common these days to mix different strains like Red Thai and Green Thai together to achieve a synergistic and balanced effect.
