Exploring the Medicinal Wealth of Nelumbo nucifera Gaertn: A Review on its Traditional Uses and Scientific Perspectives

Abstract

Introduction: Nelumbo nucifera Gaertn., commonly known as the sacred lotus, holds significant value in various traditional medicine systems such as Ayurveda, Traditional Chinese Medicine, and other ethnomedical practices. Different parts of the plant—including leaves, flowers, seeds, and rhizomes—have been traditionally utilized to address a range of health conditions, including hemorrhagic disorders, digestive disturbances, metabolic dysfunctions, and neurological ailments. Methods: This review synthesizes classical knowledge from traditional systems of medicine with contemporary scientific literature. An extensive search was conducted across major biomedical databases to compile data on the phytochemical composition, pharmacological activities, formulations, and therapeutic applications of N. nucifera. Results: Phytochemical analyses have revealed that N. nucifera is rich in bioactive constituents such as alkaloids, flavonoids, glycosides, polyphenols, and essential micronutrients. These compounds exhibit diverse pharmacological activities, including antioxidant, anti-inflammatory, hepatoprotective, antidiabetic, neuroprotective, and cardioprotective effects. Several in vitro and in vivo studies support these activities, and a variety of formulations derived from different parts of the plant are being explored for therapeutic use. Discussion: While traditional use and experimental studies highlight the broad therapeutic potential of N. nucifera, gaps remain in clinical evidence and standardization protocols. Most current data are limited to preclinical models, with insufficient human trials to establish efficacy, safety, dosage, and long-term effects. Conclusion: Nelumbo nucifera demonstrates substantial therapeutic promise, supported by both traditional knowledge and pharmacological research. However, further clinical studies, standardization of active compounds, and safety assessments are necessary to validate its integration into modern healthcare systems. Expanded scientific investigation will be essential to realize its full potential as a complementary or alternative medicinal agent.
