The present study documented medicinal plant diversity within the Environmental Education Theme Park of the Regional Institute of Education (RIE), Ajmer, Rajasthan. Field surveys were conducted during 2025–2026 through direct observation, specimen collection, photography, and interaction with local residents. Plant specimens were identified using standard floristic literature and available taxonomic monographs. A total of 113 medicinal plant species belonging to 89 genera and 50 families were recorded on the campus. The inventory comprised 106 dicot species representing 82 genera and 45 families and seven monocot species representing six genera and five families. Based on growth habit, the recorded flora included 47 trees, 38 herbs, 21 shrubs, and seven climbers. Fabaceae and Euphorbiaceae were the dominant families, each represented by six species, while Ficus was the most represented genus, with three species. Nine medicinal plant species were reported under Rare, Endangered, or Threatened categories, indicating the need for site-based conservation attention. The documented campus flora demonstrates the potential of the theme park as a practical resource for plant identification, biodiversity education, and awareness of medicinal plant conservation. Continued monitoring, taxonomic verification, voucher documentation, and appropriate in situ and ex situ conservation measures are required to support the sustainable management and educational use of these medicinal plant resources.</p> Sanjeeb K.

Its seeds, leaves, roots, and stems have been used as laxatives, analgesics, diuretics, antibiotics, antidiabetic, hepatoprotective, antihyperlipidaemic, antioxidant, and antianaemic agents, and in the treatment of malaria, influenza, and liver and urinary tract infections.</p> <p><strong>Aim:</strong> This study assessed the acute oral toxicity and median lethal dose (LD₅₀) of ethanolic leaf, stem, and root extracts of <em>S. occidentalis</em> in female Wistar rats.</p> <p><strong>Materials and Methods:</strong> Twelve nulliparous, non-pregnant female Wistar rats aged 8–12 weeks were randomly assigned to four groups (n = 3 per group). Group 1 (control) received distilled water, whereas Groups 2, 3, and 4 received 2,000 mg/kg of <em>S. occidentalis</em> leaf, stem, and root extracts, respectively, by oral administration. The rats were observed for signs of toxicity, general behaviour, and mortality for 14 days. At the end of the experiment, the rats were euthanised, and the liver, kidneys, and heart were harvested for examination.</p> <p><strong>Results:</strong> <em>S. occidentalis</em> produced no signs of toxicity or mortality during the study period; however, the leaf and stem extracts significantly (p &lt; 0.05) reduced body weight. None of the extracts significantly affected the weights of the liver, kidneys, or heart. Phytochemical screening revealed alkaloids, cardiac glycosides, phenols, tannins, flavonoids, and saponins in all extracts. Steroids and terpenoids were detected in the root and stem extracts, anthraquinones and glycosides in the root extract, and polyphenols in the stem extract. The LD₅₀ values of the <em>S. occidentalis</em> leaf, stem, and root extracts were greater than 2,000 mg/kg.</p> <p><strong>Conclusion:</strong> A single oral dose of 2,000 mg/kg of <em>S. occidentalis</em> leaf, stem, and root extracts caused no mortality or visible acute toxicity and did not significantly alter liver, kidney, or heart weights in female Wistar rats. Nevertheless, further biochemical, haematological, neurobehavioural, gross pathological, and histological assessments are required.</p> H. Bawa, M. B. Adamu, F. M. Sulaiman, A. Ali, K. A. Nura, S.
