„This species is grown for its tannins and as a honey plant.“

„This plant is now known as one of the worst invasive species in the world.“

„The tannin compounds extracted from the bark of Acacia mearnsii are commonly used in the production of soft leather. A range of other products, such as resins, thinners and adhesives, can also be made from bark extracts… Acacia mearnsii has some known medical applications, such as its use as a styptic or astringent.“

The activity of A.mearnsii bark extracts against some enteric organisms like E.coli may provide an explanation to the ethnomedicinal use of A.mearnsii in the treatment of gastro-intestinal diseases like diarrhoea and stomach ache (like tannin-rich Senegalia catechu extracts).
