Summary
Mescaline, a potent hallucinogen from the peyote cactus, profoundly influences behavior by activating the serotonin 5-HT2A receptor, triggering Ca2+ release. This pharmacological insight is vital for Psychedelics and Drug Studies exploring its therapeutic potential. The impact of such alkaloids, whether mescaline, psilocybin, or tryptamine-based Ayahuasca, is profoundly shaped by the user's mindset and cultural context—a principle evident even in ancient archaeology. Integrating these natural alkaloid insights with modern medicine offers a novel approach to well-being, highlighting Neurotransmitter Receptor Influence on Behavior.
Abstract
Peyote (Lophophora williamsii) is a cactus that contains various biologically active alkaloids—such as pellotine, anhalonidine, hordenine and mescaline. Here, mescaline induces the psychoactive effects of peyote through the activation of the serotonin 5-HT2A receptor and the subsequent release of calcium (Ca2+) from the endoplasmic reticulum (ER). Moreover, an evaluation of the therapeutic benefits of mescaline is also currently the subject of research. It is important to consider that the outcome of taking a psychedelic drug strongly depends on the mindset of the recipient and the context (set and setting principle), including ceremonies and culture. This overview serves to summarise the current state of the knowledge of the metabolism, mechanism of action and clinical application studies of peyote and mescaline. Furthermore, the benefits of the potential of peyote and mescaline are presented in a new light, setting an example for combining a form of treatment embedded in nature and ritually enriched with our current highly innovative Western medicine.
