The most commonly used histological stain, haematoxylin is a natural compound extracted from a species of tree found in Mexico and the West Indies. The extracted compound is oxidized to produce haematin, the active staining component of the haematoxylin stain. The production of histological staining solutions is an art. Only a few laboratories are capable of developing a stain of reliable vibrancy. National Diagnostics' proprietary methods achieve the finest control of the ripening process, resulting in the only commercially available Harris’ Haematoxylin with a full one year shelf-life.
