Hemin
Hemin He"min, n. [Gr. a"i^ma blood.] (Physiol. Chem.) A substance, in the form of reddish brown, microscopic, prismatic crystals, formed from dried blood by the action of strong acetic acid and common salt; -- called also Teichmann's crystals. Chemically, it is a hydrochloride of hematin. [1913 Webster]

Note: The obtaining of these small crystals, from old blood clots or suspected blood stains, constitutes one of the best evidences of the presence of blood. [1913 Webster]
