Acacia nilotica (scientifically recognized as Vachellia nilotica) is known in English as Babul, Gum Arabic Tree, or Prickly Acacia. Among the Tiv people, it is recognized as a hardy thorny tree valued for its medicinal strength, fodder use, and ability to improve poor soils rather than by multiple external names.
Gum arabic tree (Acacia nilotica, now often placed in the genus Vachellia, family Fabaceae) is a thorny tree with a broad, rounded crown, from about 2.5 metres on poor soils to 14 metres or more. Its branches carry paired white thorns, its leaves are finely divided, and its bright yellow flowers grow in round, fluffy balls. A sticky red resin seeps from the bark. Trees flower and produce pods abundantly from five to seven years old.
It grows naturally in the drier parts of Africa, the Arabian Peninsula and western Asia to India, in woodland, wooded grassland, scrub and on riverbanks that flood from time to time. It tolerates heavy clay and salty soils, several months of drought or flooding, and rainfall from 400 to 2,300 mm. Seed germinates best when fresh. Dried seed needs soaking in hot water first, and seed that has passed through grazing animals germinates readily. Outside its native range it can become an invasive weed.

In Tiv traditional medicine, Vachellia nilotica is a highly important healing tree, with bark, leaves, pods, and gum used in remedies. Preparations from the bark and pods are commonly used to treat diarrhea, dysentery, stomach disorders, coughs, colds, and chest infections. The plant is also used for skin diseases, including rashes, sores, and infections. Chewing of young twigs is practiced for oral health, helping with toothache, gum problems, and mouth cleanliness. Decoctions are sometimes used in women’s health remedies, particularly for abnormal discharge and post-childbirth care. These traditional uses align with known antimicrobial, anti-inflammatory, antioxidant, and blood-sugar-regulating properties of the plant.

Vachellia nilotica thrives well in dry savanna environments similar to those found in Tiv land. It tolerates poor, sandy, or saline soils and is highly drought-resistant, making it suitable for marginal lands. The tree is commonly propagated by seed, with seeds often soaked in hot water before planting to improve germination. It is a fast-growing species under favorable conditions and responds well to cutting and regrowth. Because it is a nitrogen-fixing tree, it is useful in soil restoration, erosion control, and agroforestry systems.
