The leaves of the Southeast Asian mitragyna speciosa tree — is best known as a finely ground powder. However, the plant is also commonly sold in other, less ubiquitous forms.
One of those forms, stem and vein kratom, exists as a middle-ground option between raw kratom plant leaves and the kratom powders that customers from around the world are well-acquainted with. In the simplest terms, stem and vein kratom is a by-product of kratom processing. Across countries like Indonesia, locals collect the leaves of the kratom tree, mitragyna speciosa, in large quantities. After cleaning the leaves and allowing them to dry in the sun, the locals de-stem and devein the leaves before grinding them into a fine powder. The raw, unprocessed leftover stems and veins are then sometimes sold as stem and vein kratom.
Even though buying stem and vein kratom is less popular among buyers, this lesser-known kratom variant does have some distinguishing properties.
Stem and vein Kratom is commonly used as a potentiator for Kratom powder as it enhances and lengthens the effects.
Another benefit of stem & vein is that it can be used during tolerance breaks for 3 – 5 days to reset tolerance to Kratom.
