Applications :
Logwood has been used for centuries as a natural source of dye, and still remains the best source of Haematoxylin, which is used in histology for staining. In its time, logwood was considered a versatile dye, and was widely used on textiles but also for paper and leather.
Pure Logwood extract dyes water in pink-purple. The dye's colour depends on the mordant used as well as the pH. It is reddish in an acid environment but bluish in an alkaline one.
