In the form of Liquor Hydrargyri Nitratis acidus and Unguentum Hydrargyri Nitratis of the old school this salt of mercury has achieved a reputation as "a stimulating application" to indolent ulcers, to the eyelids in ophthalmia, and in a variety of skin diseases such as herpes, ringworm, impetigo, lepra, psoriasis, rupia. The homœopathic authority for it is Hansen, who considers that sticking pains are its special indication, and also sticking itching . Eye affections with burning, sticking pains, photophobia, and epiphora. Mucous patches with sticking pains. Gonorrhœa with frequent burning, sticking itch on corona glandis and in sulcus coronarius. Vegetations. Hansen says Donner commends it in syphilis of the nerves and of the bones. The Schema is compiled from poisoning cases. Among the symptoms are cachexia; tremors; frequent fainting; pains so intolerable he calls for a knife to kill himself. Coldness predominates, but there is the nitric acid flush of the face.
