Acacia farnesiana, also known by its updated botanical name Vachellia farnesiana, is a thorny shrub or small tree widely recognized for its fragrant yellow flowers and traditional medicinal value. Commonly referred to as Sweet Acacia, Needle Bush, or Huisache, it holds various regional names in India, including Babul, Kikar, and Vilayati Babool. However, it is important to note that the term “Babool” is also used for Acacia nilotica, a different species, so accurate botanical identification is essential.

Botanically, Acacia farnesiana belongs to the Fabaceae (legume) family and grows as a multi-branched shrub or tree reaching heights of 4.5 to 9 meters. The plant bears small, golden-yellow, globe-shaped flowers known for their strong, sweet fragrance. These blooms typically appear in clusters and are a primary source of farnesol, a naturally occurring alcohol used in perfumes and cosmetics. The leaves are bipinnate, and each leaf base features a pair of sharp thorns, which makes the plant effective for use in natural fencing or live hedges. The tree may remain evergreen or deciduous, depending on local climate conditions.

In traditional medicine systems, especially folk and rural practices, Acacia farnesiana is used for a variety of therapeutic purposes. The leaves and bark are applied topically to treat cuts, wounds, and minor skin infections, thanks to their mild antiseptic and astringent properties. The bark is also known to have anti-inflammatory effects and can be used as a poultice to reduce swelling. In some traditional remedies, the plant is consumed in small, controlled amounts to aid digestion and treat stomach-related ailments.

Aside from its medicinal roles, Acacia farnesiana is valued for its ornamental beauty. The sweet-smelling yellow flowers make it a desirable plant for gardens and landscape decoration, especially in regions with dry climates. The durable wood is sometimes used for making tools, handles, and small furniture, although this is more common in rural settings.

While generally considered safe when used externally or in small doses, excessive or improper internal use can be harmful. Therefore, any medicinal use—especially ingestion—should be carried out under the supervision of a qualified herbalist or Ayurvedic practitioner.
