What is Mitragynine and Mitragynine Toxicity?

Mitragynine is the primary active alkaloid found in the leaves of the *Mitragyna speciosa* tree, commonly known as Kratom. Kratom is a tropical tree native to Southeast Asia, and its leaves have been used for centuries for their psychoactive effects. The substance is often marketed as a natural supplement for pain relief, energy, and mood enhancement, but it carries significant risks.

• Opioid-Like Effects: Mitragynine acts on opioid receptors in the brain, producing effects similar to those of opioids, particularly at higher doses.
• Toxicity Risk: The toxicity, or poisoning, occurs when the substance is consumed in doses that overwhelm the body's systems.
• Respiratory Depression: The most dangerous effect of high doses of Mitragynine is respiratory depression—a slowing or stopping of breathing—which can be fatal. This risk is significantly amplified when Mitragynine is mixed with other illicit medications or opioids.
• Lack of Regulation: Because Kratom is often sold as a dietary supplement, it is not regulated by the U.S. Food and Drug Administration (FDA) in the same way as pharmaceuticals, leading to inconsistent potency and purity, which increases the risk of accidental overdose or toxicity.

The tragic finding of Mitragynine toxicity as the cause of death highlights the serious and often underestimated dangers associated with unregulated substances like Kratom, even when they are perceived as "natural" or "harmless" supplements.
