How Kratom Vein Colors Work, And The Differences Between Them, According To An Expert Kratom Grower

kratom vein colors

Kratom vein colors and Kratom strains have always been somewhat of a mystery on the internet. Indeed there are multiple theories thrown around for the differences between Kratom strains, and very little science to back up any of these theories. In-fact, many people say that there aren’t any Kratom strains at all, and all Kratom is really the same. On the other hand, Kratom growers do use different fermentation processes, such as putting Kratom in a bag with water and leaving it in the sun in order to increase 7-hydroxymitragynine levels, and this gives Kratom a reddish hue, and other fermentation/drying processes are used to produce white, yellow, and gold, while green is unfermented. Also, different climate and soil conditions can produce varying alkaloid profiles in Kratom trees.

All of this being said, I recently met with a local Kratom grower, and he handed over his theory of Kratom vein colors, and it’s one of the best theories I’ve seen to date.

As can be seen in the article image above, Kratom leaves really do have different vein colors. The grower of these leaves classifies vein colors as green, white, red, pink and purple.

Apparently his theory is that the more alkaloids which are in the vein of the leaf, the more red the vein will be, with purple having the highest concentration of alkaloids, and white having the lowest concentration of alkaloids. Notably, in the image above the veins which are more light green and perhaps have a whitest tinge are considered white, while a more deep green is considered green, and also some red and pink veins can be seen. I don’t believe any of the leaves in that picture are purple veined.

There has not been any scientific studies on this theory, so therefore this theory is not empirically confirmed. However, the Kratom grower chews these leaves every day, and I trust that he has a good sense for the varying alkaloid levels among the different vein colors. Indeed, subjective evidence from someone who is constantly around live Kratom plants can be just as good as scientific evidence.

Notably, all of the different vein colors can be present on the same tree, with the younger leaves towards the top usually being white and green veined, and the leaves towards the bottom that are bigger and more mature, and therefore higher in alkaloids, having red, pink, and purple veins.

This is quite different than the classical theory that different vein colors come from different trees and different regions. According to this theory, all of the possible vein colors can be on the same tree.

Also, there is apparently a seasonal variation, with white, green, and some red in the winter, mostly green in the Spring with some white, red, and a bit of pink showing up, and the full spectrum of colors becoming apparent in the Summer, when the Kratom tree is really thriving from the heat and humidity.

Of course, it is unique for Kratom trees to have seasons at all, and in Indonesia there are no seasons, and therefore in Indonesia there is likely no vein cycle throughout the seasons. Rather, in Indonesia the full spectrum of vein colors is likely present all year.

Overall, this theory regarding vein color is one of the best I’ve seen, since instead of talking about fermentation processes and such, this theory classifies Kratom leaves based on their literal vein color, and the logic behind the theory regarding alkaloid differences makes sense, although it still needs to be proven.

On a final note, it would be impossible to classify leaves according to vein color unless you have fresh leaves. Indeed, in Indonesia the farmers generally take all the leaves off a tree and grind them together into a powder, meaning all the vein colors get mixed together. Considering that, perhaps most Kratom powder is truly a full spectrum of vein colors, rather than being a single vein color. That being said, it is not impossible that some Kratom growers in Indonesia actually separate out the different vein colors before powderizing, although that would be a tedious process and it is likely that most farmers just grind all the leaves together without sorting.
