Leaves of plants, AzadirachtaindicaNeem) and A. eriolobaare boiled in large volume of water. This decoction is used for cleaning infection and also for taking bath for the treatment of eczema in District Mirpurkhas (Sindh).
A. erioloba contain considerable amount of water soluble carbohydrates3, pods contain higher levelsof protein, and acid soluble mineral4. Leafs and stem containcalcium and phosphorus in a considerable amount5.Gum contains carbohydrate as a combination of glycoproteins. Protein constituents are hydroxyproline and serine, while carbohydrate part is mainly comprised of l-arabinose,d-galactose, and 4-O-methyl-d-glucuronic acid residues6
