Senegalia senegal (formerly Acacia senegal) is a small thorny deciduous tree from the genus Senegalia, known by the common names Rfaudraksha, Gum Acacia, Gum Arabic Tree, or Gum Senegal Tree. It is native to semi-desert regions of Sub-Saharan Africa, as well as Oman, Pakistan, west coastal India. It grows to a height of 5-12m, with a trunk up to 30 cm in diameter.[2] S. senegal 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 acacia or talh gum.[3]

Uses[edit]

Gum arabic[edit]

The tree is of great economic importance for the gum arabic it produces to be 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. Seventy percent of the world's gum arabic is produced in Sudan.

Forage[edit]

New foliage is very useful as forage.[4]

Food[edit]

Dried seeds are used as food by humans.[4]

Agriculture[edit]

Like other legume species, S. senegal fixes nitrogen within Rhizobia or nitrogen-fixing bacteria living in root nodules.[3] This nitrogen fixation enriches the poor soils where it is grown, allowing for the rotation of other crops in naturally nutrient-poor regions.

Senegalia senegal

Traditional uses[edit]

It is reportedly used as for its astringent properties, to treat bleeding, bronchitis, diarrhea, gonorrhea, leprosy, typhoid fever and upper respiratory tract infections.[4][unreliable medical source?]

Rope[edit]

Roots near the surface of the ground are quite useful in making all kinds of very strong ropes and cords. The tree bark is also used to make rope.[4]

Wood[edit]

Handles for tools, parts for weaving looms.[4]

Chemistry[edit]

A. senegal contains hentriacontane, a solid, long-chain alkane hydrocarbon. The leave also contain the psychoactive alkaloid dimethyltryptamine.[5]
