A Comprehensive Review of the Phytochemistry, Pharmacological Activities, and Safety of Tamarindusindica L.: Traditional Knowledge to Modern Therapeutics

Abstract

Background: With a long history of traditional use and a varied phytochemical composition, Tamarindusindica L. (tamarind) is a significant medicinal and food plant. Traditional and Unani medicine have reported a number of therapeutic uses for the plant's many parts, including the fruit, seeds, leaves, bark, roots, and flowers. Antioxidant, anti-inflammatory, antibacterial, antidiabetic, hepatoprotective, wound-healing, anti-angiogenic, hypolipidemic, immunomodulatory, and anticancer properties have all been further shown in recent experimental studies. However, details about its phytochemistry, pharmacological characteristics, safety, and traditional usage are still scattered across the literature. Objective: This review aims to provide a comprehensive overview of the botanical characteristics, traditional and ethnomedicinal uses, Unani perspectives, phytochemical constituents, pharmacological activities, and safety profile of Tamarindusindica, while identifying important areas for future research. Methods: Tamarindusindica's botanical traits, taxonomy, phytochemistry, traditional and ethnomedical uses, pharmacological activity, and toxicological features were all covered in pertinent published literature. Evidence from in-vitro, in-vivo, and in-silico studies as well as details from traditional Unani literature regarding its Mizaj (temperament), Afa'al (activities), medicinal applications, side effects, remedies, and alternatives were given special attention. Result: Organic acids, flavonoids, phenolic compounds, tannins, terpenoids, alkaloids, glycosides, and saponins are among the many bioactive components found in Tamarindusindica. Research has shown that several plant parts and extracts have antioxidant, antibacterial, anti-inflammatory, antihyperglycemic, hepatoprotective, wound-healing, anti-angiogenic, hypocholesterolaemic, immunomodulatory, and anticancer properties. Its usage in gastrointestinal, hepatobiliary, febrile, inflammatory, and other illnesses is described in traditional and Unani literature. Experimental toxicological investigations that are now available show a generally positive safety profile at the levels examined; however, direct comparison of results is limited because to variations in plant parts, extraction techniques, phytochemical content, experimental models, and study protocols. Conclusion: Tamarindusindica represents a promising source of bioactive compounds with significant therapeutic potential. Future investigations should focus on standardized extraction procedures, detailed pharmacokinetic and toxicological evaluations, and well-designed clinical studies to facilitate the translation of preclinical findings into evidence-based therapeutic applications.
