Mercurius Praecipitatus Ruber.
Red Precipitate. Red Oxide of Mercury. HgO. Trituration.
Clinical.-Anus, burning in. Chancroid. Gonorrhoea. Mucous patches. Pemphigus neonatorum.
Characteristics.-This intensely irritating mercurial was investigated by Hahnemann. All the usual mercurial symptoms were intensified. Hansen has used it in practice, and gives these as indications [which are not all found in the provings]: Gonorrhoea when the urethra is felt as a hard string. Phagedaenic ulcer and bubo. Indurated ulcer, deep, with red, hard edges, and especially when spreading. Syphilitic iritis when the pains have ceased. Pemphigus neonatorum and intertrigo syphilitica. Mucous patches on scrotum and by anus, with or without fissures. Eczema, acute or chronic, much sero-purulent or purulent exudation, also externally (in ointment 1 to 40 of prepared lard). Tinea tonsurans, circinata and sycosis. Folliculitis barbae (internally and externally).-These are Hansen's own observations. In the symptoms of the proving a sensation "as of a hot iron in anus moving up and down" looks like a possible keynote.
