TINCTURE (Fr. teinture,

See also:

• LAT

Lat. tinctura, tingere, to dye, stain)  , the colour with which a substance is dyed; hence, metaphorically, distinctive character or quality . The term is used in heraldry of the metals, argent, or, of the colours, gules, azure, sable, vent, &c., or of the furs, ermine, vair, &c . Since the 16th century a conventional arrangement of lines and dots gives the equivalents of these tinctures in black and white (see HERALDRY) . In medicine, a tincture is a fluid solution of the essential properties of some substance, animal, vegetable or mineral; the menstruum being either alcohol, ether or ammonia; the various kinds are accordingly distinguished as alcoholic, etherial or ammoniated tinctures .
