Calcarea Acetica calc-ac.

The clinical uses of this drug have been based chiefly upon the well-known power of Acetic acid to produce inflammations of the mucous membranes, characterized by membranous exudation; when these conditions appear in persons presenting a strongly marked Calcarea cachexia.

Clinical:
Membranous dysmenorrhœa in persons of Calcarea habit.

Clinical:
A most brilliant cure was made of an obstinate case of membranous bronchitis, which for months had resisted all other treatment; the paroxysms recurred every two or three weeks; each time it seemed as if the patient would die, until extensive casts of the membrane of the bronchi were expectorated; entirely cured by this drug.
