Mercurius Praecipitatus Albus | Materia Medica by John Henry Clarke

White Precipitate. Mercurammonium chloride. NH2HgCl. Trituration.

Clinical : Dwarfism. Eczema faciei.

Characteristics : The symptoms of Merc. praecip. alb. are taken entirely from poisonings. The most peculiar symptoms are: Green tongue; bilious stools scalding anus; and the old-mannish appearance of a child poisoned with it. Mossa (H. R., ix. 28) relates (1) a case of chronic eczema of the face in an elderly man, a moistening eruption < in winter and from exposure to cold; vesicles on a reddened, swollen skin dry into scales which exfoliate; eyelids, especially lower, oedematous, corners reddened; lachrymation; ear involved; itching and burning on head preventing sleep. Merc. praecip. alb. 3 gr. i. every third day. First the burning itching ceased. Then formation of blisters abated. Exfoliation continued a long time, but the skin finally became normal. (2) Girl, 2, eruption on face and large part of scalp, covered with thick yellow crust, matter exuding from cracks. Offensive odour; swollen cervical glands. Merc. praecip. alb. 3 gr. i once in three days cured in four weeks.

Relations : Compare: Dwarfish children, Bar. c., Syph. Eczema, Mez., Æthiops. ant.
