CONSERVATION STATUS: Evaluated as 'Least Concern' by IUCN.
MEDICINAL USES: The antibacterial activity of aqueous and ethanolic extracts of leaves of Bauhinia tomentosa have been evaluated against human pathogenic bacteria such as Escherichia coli, Salmonella typhi, Streptococcus pyrogens, Enterobacter aerogens, Pseudomonas aeruginosa, Sterptococcus faecalis, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Proteus vulgaris. Aqueous extract of leaves of Bauhinia tomentosa was evaluated for anti-ulcer activity using Alcohol-induced and Aspirin-induced ulcer model in rats. Green synthesis of gold nano particles (AuNP) using leaves extract of Bauhinia tomentosa will be evaluated for its anti cancer activity. The anti-inflammatory activity of ethyl acetate and methanol extracts of Bauhinia tomentosa (stem bark & roots) was evaluated against 5-lipo oxygenase enzyme. Ethanolic extract of Bauhinia tomentosa shows potent anti-oxidant properties, serve as free radical inhibitor.
