There is a lot of misinformation out there about kratom colors and what they mean. Some people swear that whiter-looking kratom powder keeps them up more than caffeine while others claim the same stuff has a sedative effect. Reds are most often associated with sleep or mellow relaxation but some use them in place of coffee. Greens are somewhere in the middle and are used by some to help with anxiety issues or mood imbalances.
Kratom’s vast spectrum of beneficial effects is attributable to the alkaloids, or plant chemicals, contained inside the leaf. The composition of these alkaloids varies greatly between regions, ecological and geological conditions, and weather, but our kratom is grown exclusively Borneo. The kratom leaf comes in a gold/yellow, green, red, and shades therein, many times all being found on the same tree. Stems are green or red, though this is not an indication of the leaf’s contents.
But, if all kratom leaves are naturally green veined, how do you get red, white, and yellow? This all comes down to technique. How a batch is cured and dried makes all the difference in its color and overall alkaloid profile.
The key alkaloid inside the kratom leaf is called mitragynine and it is a partial mu and delta-opioid receptor agonist. This is what makes kratom such a popular choice for pain relief. Mitragynine is estimated to be about 13 times more potent than morphine. It has also shown that it may not have abuse potential.
Another alkaloid present in kratom is called 7-hydroxymitragynine. It is said to be four times as powerful as mitragynine, but it is not present in significant quantities in the live leaf. The proper curing techniques can alter this as oxidation transforms mitragynine into 7-OH-mitragynine. Oxidation is most evident in red strains. In fact, the way a leaf is treated once it is cut down holds primary influence over what the leaf’s overall alkaloid content is going to be by the time it reaches the end user.
To get a light green color, what we refer to as white, the sun is the enemy. White kratom is made by drying the leaves away from light, heat and humidity. An indoor setting is ideal with levels of exposure to the Indonesian humidity varying depending on the desired outcome.
The goal is to prevent as much oxidation as possible and to keep the alkaloid profile virtually untouched from its live state. Theoretically there should be more mitragynine in this type of leaf compared to if it had been dried outdoors. This results in an experience that may be more upbeat and productive than usual.
Red kratom does get some of its color from the red plant material that leeches out while drying under hot, humid sun. It gets the rest of its color from oxidation. Again, oxidation is what causes mitragynine to be converted to 7-hydroxymitragynine (7-OH). This can actually happen after the leaf is cut from its tree and is the goal when trying for a red cure. There are more alkaloids to consider, some also acting on opioid receptors, but redder kratom is typically more sedating and this is due to the oxidation of mitragynine into 7-OH.
What if you want something in the middle? Green kratom is a nice balance between white and green. Users report energy, greater drive, and pain relief without too much drowsiness. This is due to kratom’s natural alkaloid profile staying as untouched as possible during the curing process.
A perfect green is achieved by drying leaves in high heat for a short period of time at medium humidity levels. Typically leaves are strung up or dried out on screens for this. There is a small bit of light used to help.
Natural yellow kratom leaves occur due to substandard nitrogen uptake by the host tree. They are found in nature randomly either by the whole tree or just individual leaves on a tree. However, farmers can influence their product to turn a yellow color by leaving red kratom out for an extra long time to let the sun bleach it out.
Some varieties, like Bentuangie, can be achieved with the right usage of fermentation bags. The timing must be just right – up to five days is usually good. If the leaves are left in for any longer there is a risk of mold growth, which results in a product that is unfit for consumers.
