Study: High-Dose Mitragynine Interacts with Cannabinoid Receptor to Impair Cognitive Functioning

A comprehensive and detailed study in mice from University of Science, Malaysia revealed mitragynine in very high doses is an agonist (binds to and activates) cannabinoid receptor Type 1 (CB1). Mice administered with high-dose mitragynine demonstrated similar reward-seeking behavior and cognitive impairment as mice administered with morphine and THC. Mice that received high-dose mitragynine, morphine, …

Study: 7-hydroxymitragynine Metabolizes into the More Potent ‘Mitragynine Pseudoindoxyl’ in Human Plasma

A study out of University of Florida published in the journal ACS Pharmacology & Translational Science found that the potency of powder kratom may be due not only to the increased level of 7-hydroxymitragynine (7-HMG), but the way the 7-HMG metabolizes in human plasma (Kamble 2020). Fresh kratom consumed traditionally in Southeast Asia has been …
