Healing and Hallucinations: A Comprehensive Look at Datura

Abstract

The Solanaceae plant family is a large clade that includes Datura, a genus of plants with many species recognized for their severe pharmacological effects via tropane alkaloids like atropine, hyoscyamine and scopolamine. These alkaloids act as antagonists of muscarinic acetylcholine receptors with leading to a truly diverse pharmacological action, ranging from anticholinergic effects all the way through hallucinogenic properties. Datura plants have been used historically in traditional medicine and rituals worldwide but are infamous for poisoning due to the risk of severe anticholinergic toxicity, including death. Nevertheless, their pharmacology has become of interest for research due to potential therapeutic applications: specifically in controlling nauseousness and perhaps neurological disorders. In this review, we provide a summary of the botanical description and cultivation methods in addition to those on traditional use practices concerning phytochemistry, pharmacology and toxicology as compared with evidence-based information together emphasizing cautions against availability without stringent regulatory consideration for its modern medical uses or ritualistic purposes.
