catechun.

/ˈkatɪ(t)ʃuː/

Etymology: In modern Latin catechu (also German katechu , kateschu ), apparently < Malay kachu , (Tamil, Telugu, Kannada kācchu , kaycchu , kāshu ) catechu (of acacia). The direct representatives of the latter are Portuguese cacho , French cachou ; the exact history of the form catechu is obscure. See also the other names cachou n., cate n.², cutch n.¹

A name given to several astringent substances, containing from 40 to 55 per cent. of tannin, which are obtained from the bark, wood, or fruits of various Eastern trees and shrubs. They are used in medicine, and in tanning, calico printing, and dyeing. Also attributive and in other combinations.The name was apparently first applied (in Europe) to the pale sort called also gambier n., obtained from the leaves and young shoots of Uncaria (or Nauclea) Gambir; this is the Catechu of Pharmacy ( New Sydenham Soc. Lexicon): when first brought to Europe in the 17th cent. it was from its appearance believed to be an earth, and called Terra Japonica (Terra Japonica n.). The dark sort obtained from the wood of Acacia Catechu, is more commonly called cutch n.¹; of this Pegu Catechu is a good variety. (There is doubt whether the connection with Japan assumed in the name terra japonici is not purely imaginary, and owing to the Burmese name for Acacia Catechu, sha-pin, shabin, or shaben.)
