PRODUCT USAGE
Logwood Extract, derived from the heartwood of Haematoxylum campechianum, is a historic natural dye that remains indispensable in both biomedicine and industrial dyeing. In histology, its oxidized form, Haematein, is a crucial component of the H&E stain (Hematoxylin and Eosin), used to stain cell nuclei deep blue for pathological diagnosis—the gold standard in medical labs. In the textile and leather industries, it serves as a premium natural dyestuff that, when combined with different mordants, produces deep, light-fast shades of black, purple, and blue on silk, wool, cotton, and leather. Additionally, its eco-friendly nature makes it a popular choice for high-end natural inks and botanical hair dyes in the personal care sector.
