Haematoxylin is the colouring matter of logwood, or Haematoxylon campechianum. This colouring matter is a constituent part of all the colours prepared with logwood, and the changes which it undergoes by the action of acids and alkalies render it useful as a reagent to detect their presence.

Haematoxylin is the colouring principle extracted from logwood. It forms yellow crystals that are slightly soluble in cold water. It is chemically of a phenolic character, and on oxidation becomes converted into a red substance, haematin. Research Haematoxylin
