Description
Ammoniacum, or gum ammoniac, is a gum-resin exuded from the stem of the perennial herb Dorema ammoniacum of the umbel family (Apiaceae). The plant grows to the height of 2½ or 3 meters (8 or 9 ft.) and its whole stem is pervaded with a milky juice, which oozes out on an incision being made at any part. This juice quickly hardens into round tears, forming the "tear ammoniacum" of commerce. "Lump ammoniacum", the other form of the substance, consists of aggregations of tears, frequently incorporating fragments of the plant itself, as well as other foreign bodies. When soaked in hot water will yield a milky substance used by calligraphers for gilding.
