Study Information
Regeneration of sciatic nerve: An extract administered in a dose of 1.6 mg/100 g parenterally every 4th day up to 120 days in rats having experimental injury of sciatic nerve, exhibited 30–40% higher results in the process of regeneration of sciatic nerve as compared to the hydrocortisone group.
Antidepressant action: In Mexico, aqueous extracts from dried leaves of M. pudica are used to alleviate depression. In a study, behavioral actions of aqueous extracts of M. pudica at various concentrations were tested. The data indicated that M. pudica produces antidepressant effects in the rat.
Anticonvulsant action: The decoction of M. pudica leaves given intraperitoneally at a dose of 1000–4000 mg/kg protected mice against pentylenetetrazole and strychnine-induced seizures. M. pudica had no effect against picrotoxin-induced seizures.
Hyperglycemic effect: Ethanolic extracts of M. pudica leaves given by oral route to mice at a dose of 250 mg/kg showed a significant hyperglycemic effect.
Diuretic effect: Decoction of leaves of M. pudica in doses of 200, 500, 1000, and 2000 mg/kg in rats and dogs exhibited diuretic activity. The activity in rats at 250 mg/kg dose was found to be 82% of standard diuretic (hydrochlorthiazide 2.5 mg/kg) treated group of rats. There was significant reduction (above 50%) of Na+ and Cl- excretion without affecting K+ excretion.
Effect on uterine bleeding: Aqueous extracts of the root powder in pilot studies on patients with dysfunction uterine bleeding gave promising results.
Spasmogenetic potential: Ethanol extracts (50%) of the whole plant exhibited spasmogenetic activity in isolated guinea pig ileum.
Antifungal activity: The methanolic extract and aqueous extract of 100, 200, and 500 mg were tested against different fungal pathogens, Aspergillus fumigates for their antifungal activity. It was demonstrated by a well diffusion assay.
Antimicrobial properties: Four of the seven tested medicinal plants exhibited antimicrobial activity against Vibrio cholerae. These seven plants are: Ficus capensis, Mitragyna stipulosa, Entada Africana, Piliostigma reticulatum, Terminalia avicennoides, M. pudica, and Lannea acid. M. pudica showed antimicrobial activity.
Wound healing activity: The roots of M. pudica were studied for wound healing activity by incorporating the methanolic and the total aqueous extracts in simple ointment base B.P. in concentration of 0.5% (w/w), 1% (w/w), and 2% (w/w). Wound healing activity was studied in three types of model in rats viz. excision, incision, and estimation of biochemical parameters. Treatment of wound with ointment containing 2% (w/w) the methanolic and 2% (w/w) the total aqueous extract exhibited significant (P < 0.001) wound healing activity. The methanolic extract exhibited good wound healing activity probably due to phenols constituents
