Editing Acacia sensu lato (section)

===Uses in folk medicine===
''Acacia'' species have possible uses in [[folk medicine]]. A 19th-century Ethiopian medical text describes a potion made from an Ethiopian species (known as ''grar'') mixed with the root of the ''tacha'', then boiled, as a cure for [[rabies]].<ref>Richard Pankhurst, ''An Introduction to the Medical History of Ethiopia'' (Trenton: Red Sea Press, 1990), p. 97</ref>

An [[astringent]] medicine high in [[tannin]]s, called [[catechu]] or cutch, is procured from several species, but more especially from ''[[Senegalia catechu]]'' (syn. ''Acacia catechu''), by boiling down the wood and evaporating the solution so as to get an extract.<ref>{{cite web|url=http://www.henriettesherbal.com/eclectic/usdisp/uncaria-gamb.html |title=An OCR'd version of the US Dispensatory by Remington and Wood, 1918 |publisher=Henriettesherbal.com |access-date=2013-03-06}}</ref><ref>{{cite web |url=http://www.fao.org/docrep/V8879E/v8879e05.htm |title=Cutch and catechu plant origin from the Food and Agriculture (FAO) department of the United Nations.
