Also known as the 'Gum Arabic Tree,' this plant is astringent, demulcent, nutritive, expectorant, and also an aphrodisiac. It is traditionally used, as a strong decoction, in the treatment of gonorrhea with dropsy, cough, diarrhea, as a gargle for spongy gums, apthous stomatitis, cancer, and sore throat, or as a douche or enema in gonorrhea, cystitis, vaginitis, leucorrhea, piles, and anal prolapse. It is helpful in managing conditions involving hemmorrhagic ulcers and wounds, dysentery, diabetes mellitus, conjuctivitis, fever, burns, bleeding, catarrh, sexual debility, and genito-urinary complaints.

Acacia Bark (Acacia arabica), also known as Wattle Bark, is obtained from the chief of the Australian Wattles, the Black Wattle, and is collected from wild or cultivated trees, seven years old or more, and must be allowed to mature for a year before being used medicinally.

Acacia Bark contains from 24-42% of tannin (gallic acid). Acacia Bark's powerful astringency causes this herb to be extensively employed in the tanning industry.

Medicinally, Acacia Bark is employed as a substitute for Oak Bark. Acacia Bark has special use in diarrhea, mainly in the form of a decoction, the British Pharmacopoeia preparation being 6 parts in 100 administered in doses of 1/2 to 2 fluid ounces. The decoction also is used as an astringent gargle, lotion, or injection.

A liquid extract is prepared from the bark, administered in India for its astringent properties in doses of 1/2 to 1 fluid, but the use of both gum and bark for industrial purposes is much larger than their use in medicine. The bark, under the name of Babul, is used for tanning, and also for dyeing various shades of brown.
