  • Holarrhena antidysenterica has been widely used in ayurveda and Plant Science Today, ISSN 2348-1900 (online) AJEET ET AL 10 has several ethnomedicinal uses, recent research have shown its extensive pharmacological role. Its bioactive constituents-including steroidal alkaloids such as conessine, kurchine, holarrhenine, flavonoids, tannins and phenolic compounds exhibit antioxidant, anti-inflammatory, hepatoprotective and neuroprotective activities. Experiments show that by lowering oxidative stress, boosting endogenous antioxidant enzyme activity, preserving cellular membrane integrity and modifying pro-inflammatory mediators, H. antidysenterica promotes liver health and preserves hepatic architecture and function. It also shows neuroprotective benefits by enhancing cholinergic signaling, reducing oxidative neuronal damage and preventing neuroinflammation, indicating potential like importance Parkinson's and Alzheimer's diseases. in neurodegenerative diseases Despite these promising preclinical findings, research has largely been limited to in vitro and animal studies. Clinical research is critically needed to establish safety, optimal dosage, pharmacokinetics and in humans. long-term Standardising plant extracts and identifying bioactive markers are crucial for ensuring therapeutic consistency and repeatability. Future research should focus on elucidating molecular pathways to develop novel therapeutic candidates derived from plants.
