757. Solution of Acetate of Ammonia is a most useful diaphoretic. It is used externally as a discutient, as a lotion to inflamed milk-breasts, as an eye-wash, and a lotion in scald head. It is given internally to promote perspiration in febrile diseases, which it does most effectually, especially when combined with a camphor mixture. This is the article so frequently met with in prescriptions, and called spirits of mindererus. Dose, from a half to one and a half ounces every three or four hours.
758. Antimony.--Tartar emetic is diaphoretic, emetic, expectorant, alterative, and rubefacient. It is used externally as an irritant in white swellings and deep-seated inflammations, in the form of an ointment. It is given internally in pleurisy, bilious fevers, and many other diseases, but its exhibition requires the skill of a medical man, to watch its effects. Dose, from one-sixth of a grain to four grains. Caution.--It is a poison, and therefore requires great care in its administration.
759. Antimonial Powder is a diaphoretic, emetic, and alterative. It is given internally, in febrile diseases, to produce determination to the skin, and is useful in rheumatism, when combined with opium or calomel.
