Botanical Overview
Umbrella Thorn (Acacia tortilis) is a species in the Fabaceae family. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 26 compounds in this species, suggesting potential medicinal value.

General Description
Vachellia tortilis, widely known as Acacia tortilis but now attributed to the genus Vachellia in the Fabaceae subfamily Mimosoideae, is the umbrella thorn acacia, also known as umbrella thorn and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa, but also occurring in the Middle East.
