Any of several acacia trees, such as Acacia arabica or Acacia nilotica, that produce gums, dyes, and tannins. Babul gum is similar to gum arabic. A dark brown juice pressed from the fruit of these trees contains about 12% tannins (gallic and tannic acids) and a dark red-brown water soluble dye. The tree bark is also a useful source of tannins and dyes.
