The current study uses rodent models to explore the anxiolytic properties of Hemidesmus indicus' ethanolic extract (EEHI). Hemidesmus indicus, an evergreen plant well-known for its therapeutic characteristics, has been widely used in Ayurvedic medicine to treat a variety of conditions, including anxiety. This study seeks to give scientific validation for its anxiolytic properties. The ethanolic extract was made using normal extraction processes and given to rodents in varied doses (100,200 and 400 mg/kg). The anxiolytic activity was assessed using a variety of widely recognized behavioural assays, including the Elevated Plus Maze (EPM), Open Field Test (OFT), and Light-Dark Box (LDB) test. Diazepam (2 mg/kg) served as the standard reference drug. The results revealed that EEHI significantly reduced anxiety-like behaviours in all three tests when compared to the control group. In the EPM test, EEHI-treated rodents spent more time and entered the open arms. In the OFT, ambulation, rearing and assisted rearing increased, indicating lower levels of anxiety. The LDB test supported these findings, with a significant increase in time spent in the light compartment. The study suggests that EEHI has promising anxiolytic activity and may offer a natural treatment alternative for anxiety disorders. Further research is needed to isolate specific active molecules and better understand the underlying mechanisms of action.
