Description
About White Maeng Da
White Maeng Da is a white-vein Mitragyna speciosa powder. "Maeng Da" loosely translates from Thai as "pimp grade" and is a marketing designation for selectively graded leaf, not a specific region. The source leaf is harvested earlier in the maturity cycle, when the central vein still reads as white.
After harvest the leaves are dried indoors with minimal direct sunlight to preserve the lighter coloration, then milled to a uniform fine grind and packed by hand in Poughkeepsie, NY. The current batch and its full lab panel are published on our COA dashboard by batch number.
Alkaloid Profile
The alkaloids most quantified for White Maeng Da, measured by HPLC against the dry weight of the milled leaf. 7-Hydroxymitragynine is trace-level and naturally occurring, never concentrated.
Product Specifications
From Leaf to Mill
01 Hand Harvest
Mature leaves picked at peak vein-color expression by farmers we have worked with since 2019.
02 Indoor Drying
Five-day cure in humidity-controlled rooms. Never on the ground, never UV-bleached.
03 Fine Milling
The dried leaf is milled to a fine, even powder that suspends cleanly.
04 Lab Panel
Independent labs verify alkaloid ratios, heavy metals, salmonella, and total plate count.
