Morphology
This is a straightforward adjective + noun composition: 'black' simply modifies 'catechu', so if a learner knows 'catechu' as a resin/extract, 'black catechu' will be understood as a dark or black form of that extract. The meaning is directly compositional and follows common cross-linguistic adjective+noun patterns, making it immediately comprehensible to learners who know both constituents.
Etymology
Black catechu comes from a dark extract made by boiling the heartwood of the Acacia tree until a thick, black substance remains. People used this sticky material to 'dye' cloth, 'tan' leather and 'preserve' nets, so the word black tells its colour and catechu names the extract.
