Scope note:

A natural catechu dyestuff and tanning agent obtained from the heartwood, leaves, pods and twigs of several trees, such as Acacia catechu or Uncaria gambier, that are native to southeast Asia and India. The primary colorant in cutch is catechin. Cutch was used in India since ancient times. It was exported to Japan and China as early as the 1500s but was not used in Europe until the 1800s. Used to produce shades of brown, black, and olive; also employed in tanning leather.
