 Traditional
uses: In Ayurvedic medicine, Acacia leaves, flowers,
and pods have long been used to expel worms, to staunch
bleeding, heal wounds, and suppress the coughing up
of blood. Its strong astringent action is used to contract
and toughen mucous membranes throughout the body in
much the same way as witch hazel or oak bark.
Black Catechu is used internally for chronic catarrh
of the mucous membranes, dysentery, and bleeding. In
Chinese medicine it is used for poorly healing ulcers,
weeping skin diseases, oral ulcers with bleeding, and
traumatic injuries. A small piece of cutch can be dissolved
in the mouth to stop bleeding gums or heal canker sores.
In Ayurvedic medicine, decoctions of the bark and heartwood
are used for sore throats.
Decoctions made from the powdered leaves, stems, and
pods are taken for shigella, malaria, dysentery, and
diarrhea. The brew is both antimicrobial and anti-inflammatory.
An infusion of the flowers and leaves is taken for gastrointestinal
inflammations. The flowers are also sedating.
The roots make a mucilaginous tea that is both antibacterial
and anti-inflammatory. It helps soothe mucous membranes
from the mouth through to the anus, reducing inflammation
and attacking microbial infections.
