Black Catechu is a deciduous, thorny tree which grows up to 15 m (50 ft) in height. The plant is called khair  in Hindi, and kachu in Malay, hence the name was Latinized to “catechu” in Linnaean taxonomy, as the type-species from which the extracts cutch and catechu are derived.

The heart of the tree after felling is used to make Black Catechu.

Please note that Pale Catechu is an extract made from the leaves and young shoots of Uncaria Gambier (Roxb.), a member of the order Rubiaceae, not an Acacia. It occurs in commerce in dark or pale-brown cubes with a dull, powdery fracture, or sometimes in lozenge form.

Black Catechu occurs in black, shining pieces or cakes.
