Toxicity Profiles of Common Herbal Medicines: A Pharmacological Insight into Benefits and Risks

Abstract

Herbal medicines are globally perceived as natural and safe alternatives to allopathic treatments. However, several plant-based compounds have been implicated in adverse effects, ranging from mild gastrointestinal disturbances to severe organ damage. This paper reviews the toxicological profiles of widely used herbal drugs such as Aloe vera, Aristolochiafangchi, Withaniasomnifera, and Ginkgo biloba. The pharmacological mechanisms of toxicity—such as nephrotoxicity, hepatotoxicity, and neurotoxicity—are analyzed in both animal and clinical studies. The paper stresses the need for stringent regulatory frameworks, standardization of herbal formulations, and public education on dosage and contraindications.
