Hematoxylin is to histology what water is to a human being. For over 300 years, Hematoxylin has been extracted from the heartwood of a Haematoxylon campechianum tree and oxidized to form haematein. The freshly cut logwood is colorless, but during atmospheric oxidation becomes dark reddish-brown. This compound in turn becomes Hematoxylin, the lifeblood of histology, mainly for it’s part in the H&E Staining procedure where it's counterstained by Eosin Y. In most instances, the dye is used with a mordant such as aluminum or iron.

Before it's reign as a histological stain, hematoxylin was used to dye textiles, making it highly sought after. After first being introduced in England, the Parliament banned Hematoxylin in 1580. Mostly because certain dyers felt that the dye was not colorfast. The law was repealed nearly 100 years later and demand for Hematoxylin greatly increased. In many cases during the 1700's, countries fought over the main production area (current day Belize), and freighter ships taking the dye back to Europe were frequently the target of pirates and privateers. Hematoxylin didn't appear in the medical industry until 1840.

Hematoxylin is a primary stain known for its superb nuclear staining, producing blue to purple nuclei against a pink to red background, counterstained by Eosin Y.
