Salvinorin A is a natural compound found in the leaves of the Salvia divinorum plant, which is native to Mexico. It is known for its potent psychoactive effects, making it one of the most powerful naturally occurring hallucinogens. Salvinorin A acts primarily on the kappa-opioid receptors in the brain, leading to altered perceptions and experiences. Due to its intense effects, Salvinorin A is often used in controlled settings for research purposes. It is not classified as a controlled substance in many regions, but its use can lead to unpredictable psychological experiences. Caution is advised for those considering its use.
