The species is native to Tropical Africa, from Ivory Coast in West Africa eastwards to Ethiopia and Kenya and southwards to Angola and Tanzania. [5]
In ethnomedcine, some studies have been conducted on the leaves, roots and stem bark of the species. Oleane and acacic acid type saponins were identified in root extracts of the species. [3] [6] The triterpenoids, lupeol and lepenone, betulic acid and benzyl alcohol have been identified in extracts of the plant. [7]
Stem bark extracts of the species are used in decoctions for the treatment of diarrhea in Nyanza, Kenya. The bark stem is also used to treat dermatological, respiratory and odontological ailments. [3] However, consumption of high doses of herbal remedies containing Albizia coriaria can be toxic.
Wood is traded as timber and also used in making poles, pestles and mortars and in making furniture. [3] It is also used for firewood and charcoal. [8]
Saponins, also selectively referred to as triterpene glycosides, are bitter-tasting usually toxic plant-derived organic chemicals that have a foamy quality when agitated in water. They are widely distributed but found particularly in soapwort, a flowering plant, the soapbark tree and soybeans. They are used in soaps, medicines, fire extinguishers, speciously as dietary supplements, for synthesis of steroids, and in carbonated beverages. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin and quillaia, a bark extract used in beverages.
