Below are the main rubriks (i.e strongest indications or symptoms) of Ammonium Carbonicum in traditional homeopathic usage, not approved by the FDA.
Have you ever used Ammonium Carbonicum? Yes No
Nose-bleed when washing the face in the morning.
Weak, anaemic, flabby women. Weak, no reaction. Addicted to the smelling bottle.
Tendency to gangrenous degeneration of glands, as in scarlatina; the parotids.
Another frequently verified symptom of the nose is epistaxis while flashing the face. (Kali Carb Kali carbonicum). I don't know why it comes on then, but it does, and Ammonium Carbonicum cures it. The only other affection in which I have found it very useful is scarlatina. The body is very red, almost bluish-red, and the throat seems to be the center where the force of the disease seems to be expended in malignant intensity. The eruption is faintly developed, or has seemed to disappear, from sheer inability from weakness of the patient's vitality to keep it on the surface (Zincum Metallicum Zinc. has convulsions from the same cause). Erysipelas of old, debilitated persons comes under the same head. Cerebral symptoms, simulating a drunken stupor, are present in both cases. The whole system seems to be overpowered by the toxic effect of the disease poison. (See also Ailanthus Ailanthus). Ammonium carb. will sometimes help us out in such cases.
