Background: Plants have been the basis for many medicinal compounds that are used in modern-day medicine, screening plants bioactive is a way of identifying and developing new antimicrobials less expensive with improved safety efficacy. Objective: The objective this study was to investigate vitro antimicrobial activity Azadirachta indica (neem) using leaf extracts Ethanol, Petroleum ether, Ethy...

Four weeds (Acorus calamus, Artemisia tridentata, Heliopsis longipes, and Tagetes minuta) and three cultivated plants (Azadirachta indica, Mammea americana, and Ocimum basilicum) are potential candidates for crop development and commercialization for sources of insect attractants, repellants, or toxicants. Although all could be commercially viable, the neem tree (A. indica) is by far the most l...

OBJECTIVE To evaluate the efficacy of Neem (Azadirachta indica) experimental gel for the prevention of erosive wear on bovine dentin, in vitro. MATERIAL AND METHODS One hundred dentin blocks were allocated into 5 experimental groups (20 samples each): C (control group, without gel); CG (control group, only base gel); F (fluoride gel, 1.23% NaF; pH 4.1, Dentsply; Brazil); N (Neem gel, 10% neem...

The present study was to evaluate effect of herbal feed additives on methane and total gas production during the rumen fermentation for environment and animal health concern. Different parts of the five medicinal plants were selected such as leaf and small stems of Ocimum sanctum (Tulsi), roots of Curcuma longa (Haldi), fruits of Emblica officinalis (Amla), leaves of Azadirachta indica (Neem) a...

This study presents larvicidal effect of neem (Azadirachta indica) and karanja (Pongamia glabra) oil encapsulated calcium alginate beads (individuals and combination) against mosquito species (Aedes aegypti). Studies were conducted by combining these two oils with and without converting into alginate based encapsulation formulation. Combination (30% neem oil and 70% karanja oil) was found to be...

BACKGROUND Azadirachta indica has been reported to correct altered glycaemia in diabetes. OBJECTIVE The aqueous extract of A. indica leaf and bark has been evaluated for its effect on antioxidant status of alloxan diabetic rats and compared with insulin treatment. MATERIALS AND METHODS The oral effective dose of A. indica leaf (500 mg/kg body weight) and A. indica bark (100 mg/kg body weigh...

Hypoglycaemic effect was observed with Azadirachta indica when given as a leaf extract and seed oil, in normal as well as diabetic rabbits. The effect, however, was more pronounced in diabetic animals in which administration for 4 weeks after alloxan induced diabetes, significantly reduced blood glucose levels. Hypoglycaemic effect was comparable to that of glibenclamide. Pretreatment with A. i...

ZnS nanoparticles have been synthesized using various amounts of aqueous Azadirachta Indica (Neem) leaf extract as capping agent and stabilizer. The synthesized nanoparticles were studied by FTIR, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive analysis of X-rays (EDAX) and UV-Visible spectroscopy. FTIR spect...

Addictive tobacco habit, both oral use and smoking, continues to be a major public health problem despite the availability of pharmacotherapeutic cessation aids. Long lasting abstinence rates following tobacco cessation measures remain less than optimal Several alternative treatments have been studied for tobacco cessation including natural products, such as Avena sativa1, lobeline2, mint snuff...

Neem leaf alcoholic extract (NLE) was investigated for its effects on the ECG and blood pressure of rat. Intravenous administration of NLE (100, 300 and 1000 mg/kg) resulted in initial bradycardia followed by cardiac arrhythmia in rats. NLE produced a significant and dose-related fall in blood pressure which was immediate, sharp and persistent. Pre-treatment with either atropine or mepyramine f...
