Alchornea species: distribution, traditional uses, phytochemistry, pharmacology activities, and prospects-an updated review

Alchornea Sw. (Euphorbiaceae) is widely distributed across Africa, Asia, and South America, with representative species such as A. cordifolia , A. laxiflora , and A. floribunda , reflecting broad biogeography and significant ethnomedicinal importance. Traditional applications of the genus converge on the management of infections, inflammatory conditions, malaria, gastrointestinal disorders, and wound care. Phytochemical investigations have revealed a chemically diverse foundation comprising alkaloids, flavonoids, phenolic compounds, steroids, and fatty acids. Collectively, Alchornea has emerged as a pharmacopeia of multipotent natural products, demonstrating antimicrobial, anti-inflammatory, antioxidant, antiplasmodial, hepatoprotective, immunomodulatory, wound-healing, and neuroprotective potentials. Expanding upon previous reviews, this study offers a comprehensive and up-to-date overview of the distribution, traditional medicinal applications, phytochemical constituents, pharmacological properties, and potential future directions related to Alchornea species. By integrating phytochemical diversity with pharmacological evidence, this review underscores the genus as a valuable reservoir of bioactive metabolites. Furthermore, it highlights existing research gaps in mechanisms of action, pharmacokinetics, toxicity, and clinical validation, thereby outlining key directions for future investigations that may accelerate the translation of Alchornea from traditional medicine to evidence-based therapeutics.
