In a Nutshell:
* Senegalia senegal (until recently known as Acacia senegal) is a small thorny deciduous tree from the genus Senegalia, which is known by several common names, including Gum acacia, Gum arabic tree, Sudan gum and Sudan gum arabic.
* Sudan is the source of the world's highest quality gum arabic, known locally as hashab gum in contrast to the related, but inferior, gum arabic from Red acaciaor talah gum.
* The tree is of great economic importance for the gum arabic it produces which is used as a food additive, in crafts, and as a cosmetic. The gum is drained from cuts in the bark, and an individual tree will yield 200 to 300 grams.
* New foliage is very useful as forage. Leaves and pods of S. senegal are browsed by domestic and wild ruminants.
* Dried seeds are used as food by humans.
* S. senegal fixes nitrogen within Rhizobia or nitrogen-fixing bacteria living in root nodules. This nitrogen fixation enriches the poor soils where it is grown, allowing for the rotation of other crops in naturally nutrient-poor regions.
* It has been reportedly used for its astringent properties, to treat bleeding, bronchitis, cough, diarrhea, dysentery, catarrh, gonorrhea, leprosy, typhoid feverand upper respiratory tract infections.
* S. senegal contains hentriacontane, a solid, long-chain alkane hydrocarbon. The leaf also contain the psychoactive alkaloid dimethyltryptamine. more...
