Mitragynine is a natural compound found in the leaves of the Mitragyna speciosa tree, commonly known as kratom. This substance is primarily known for its psychoactive properties, which can produce effects similar to both stimulants and sedatives, depending on the dosage. It interacts with opioid receptors in the brain, leading to pain relief and mood enhancement. In many regions, mitragynine is used for its potential therapeutic benefits, including managing chronic pain and alleviating anxiety. However, its safety and efficacy are still under research, and it has raised concerns regarding addiction and withdrawal symptoms, prompting regulatory scrutiny in various countries.
