Acacia (Gum) Botanical: Acacia nilotica (LINN.) Family: N.O. Leguminosae Acacia Nilotica (LINN.) Adulteration Chemical Constituents Medicinal Action and Uses Dosages ---Part Used--- Gummy Exudation from stem. ACACIA NILOTICA (LINN.) All the gum-yielding Acacias exhibit the same habit and general appearance, differing only in technical characters. They are spiny shrubs or small trees, preferring sandy or sterile regions, with the climate dry during the greater part of the year. The gum harvest from the various species lasts about five weeks. About the middle of November, after the rainy season, it exudes spontaneously from the trunk and principal branches, but the flow is generally stimulated by incisions in the bark, a thin strip, 2 to 3 feet in length and 1 to 3 inches wide being torn off. In about fifteen days it thickens in the furrow down which it runs, hardening on exposure to the air, usually in the form of round or oval tears, about the size of a pigeon's egg, but sometimes in vermicular forms, white or red, according to whether the species is a white or red gum tree. About the middle of December, the Moors commence the harvesting. The masses of gum are collected, either while adhering to the bark, or after it falls to the ground, the entire product, often of various species, thus collected, is packed in baskets and very large sacks of tanned leather and brought on camels and bullocks to the centres of accumulation and then to the points of export, chiefly Suakin, Alexandria, or - in Senegambia - St. Louis. It is then known as 'Acacia sorts,' the term being equivalent to 'unassorted Acacia.' The unsorted gums show the widest variation as to size of fragments, whiteness, clearness, freedom from Acacia (Gum) ( Acacia nilotica printed as Mimosa nilotica ) Click on graphic for larger image

adhering matter, etc. It is next sorted or 'picked' in accordance with these differences. There are many kinds of Acacia Gum in commerce: KORDOFAN CUM , collected in Upper Egypt and the Sudan, in Kordofan, Dafur and Arabia, and exported from Alexandria, is considered the best and is the kind generally used in pharmacy. It consists of small, irregular pieces, commonly whitish, or slightly tinged with yellow, and is freer from impurities than most other commercial varieties. But those known in commerce as 'Turkey sorts' and 'Trieste picked,' which are brought from the Sudan by way of Suakin, are equally suitable for medicinal use. SENEGAL GUM, of two varieties, produced by two different trees, one yielding a white, the other a red gum, is usually in roundish or oval unbroken pieces of various sizes, larger than those of Turkey Gum, less brittle and pulverizable, less fissured and often occurs in long, cylindrical or curved pieces. The term 'Gum Senegal' is not, strictly speaking, synonymous with Gum Acacia, though it is commonly so used. Gum Acacia is the name originally pertaining to Sudan, Kordofan or Egyptian (hashabi) Gum, which possesses properties rendering it superior and always preferred to any other known to commerce.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
