Uses

Alcoholic beverages

The bark is used in the production of alcoholic beverages.^[4]

Forage

Acacia angustissima's seeds are high in protein and are somewhat useful as forage for livestock.^[2] The tree has a tannin content of 6%, which inhibits the ability of livestock to make use of the tree's protein.^[4]

Medicine

The indigenous Tzotzil and Tzeltal Maya people of Mexico use A. angustissima to treat digestive tract problems. They also use it to treat toothache, rheumatoid arthritis and cuts of the skin. Experiments have shown that A. angustissima mildly inhibits the growth of Escherichia coli and Staphylococcus aureus.^[4]

Propagation

There are 90,000–100,000 seeds/kg.^[5]
