Calumba Sentence Examples

The wood contains no tannin, and for this reason quassia, like chiretta and calumba, may be preserved with iron.

Substances containing tannic or gallic acid turn black when compounded with a ferric salt, so it cannot be used in combination with vegetable astringents except with the infusion of quassia or calumba.
