This is a scientific paper that breaks down regional differences between kratom strains.
Initial Critique- They use a super small sample size and so attempting to create a theory on the regional differences between strains is a bit futile, but this is my prime interest when it comes to kratom and so I am going to make a stab at it.
Regional Differences in Kratom Strain Based on the Paper-
- Borneo: Kratom from Borneo is often found to have higher concentrations of alkaloids like mitragynine and 7-hydroxymitragynine which may result in potent effects that can be stimulating or relaxing depending on the strain. Researchers suggest that the soil, climate, and cultivation practices on the island of Kalimantan may create unique conditions that lead to increased alkaloid synthesis in the plant.
- Malay Peninsula: Strains originating from the Malay Peninsula, such as Green Malay, often have higher levels of mitragynine, which is linked to its analgesic (pain-relieving) properties. Some studies suggest that Malay strains might have a lower overall alkaloid yield but tend to produce higher concentrations of mitragynine relative to other alkaloids, which can influence the plant’s effects.
- Thailand: Kratom from Thailand is often noted for a different alkaloid profile, which includes the presence of speciogynine and 7-hydroxymitragynine, compounds that are believed to contribute to the opioid-like effects of kratom. Strains from Thailand are sometimes linked to more sedative effects due to these compounds.
My main interest is attempting to define “kratom strains” and I have been doing statistical breakdowns of kratom vendor lab reports. As of yet have been unable to find a statistically significant difference when I break things down based on “strain color” or location of grow.
It seems that the mixing of kratom seeds in SE Asia has been going on for many years now and at this point any sort of original regional differences has been mixed out of recognition.
If anyone knows of a way we might be able to answer the question of “kratom strains” then please leave a comment to help aid in my research.
