Leaves appear with 2-5 pairs of pinnae and 8-15 pairs of bluish-green leaflets. Thorns aredark brownin color.Flowers are golden yellow in color and solitary or in cluster form. Pods are usually green in color, half-moon shaped, flattened, and spongy.Seeds lie in several rows1,2.

Ethnomedicinal Uses in Skin Diseases

Scabies:

  1. Acacia eriolobaE. Meyer (Camel thorn) herb are boiled in large volume of water. This water is used for taking bath daily for one week for the treatment of scabies in District Jamshoro and QamberShahdadkot (Sindh).
  2. Leaves of plants, AzadirachtaindicaA. Juss (Neem) and A. eriolobaare boiled in little amount of water, and then oil is added in it. The prepared remedy is applied topically on scabies in District Tharparker (Sindh).

 

Infection and eczema:

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).

Chemical Constituents

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
