|Gum Arabic Tree|
(L.) Britton & P. Wilson
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. 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.
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.
Like other legume species, 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 is reportedly used as for its astringent properties, to treat bleeding, bronchitis, diarrhea, gonorrhea, leprosy, typhoid fever and upper respiratory tract infections.[unreliable medical source?]
