These varieties of Sulphur differ only in their various degrees of purity.

Med. Prop. and Action. Sulphur is diaphoretic and alterative, in doses of gr. x. - gr. xxx. In doses of gr. lx. - gr. clxxx. it is a mild and certain aperient, producing solid, soft stools, of a light yellow colour, and smelling strongly of sulphuretted hydrogen. Dr. Paris considers that its action as an aperient is limited to the muscular coat of the large intestines; but Sundelin, perhaps more correctly, considers that it operates specifically on the mucous membrane of the intestines. When taken internally, it is absorbed into the system, and has been detected by Eberhard in the chyle, the lymphatics, and the vessels of the mesentery: a large portion of it passes off by the bowels, part is oxidized and converted into Sulphuric Acid, which is eliminated by the kidneys; and another portion passes off by the skin in the form of sulphuretted hydrogen. In the last way, it proves useful in cutaneous diseases. Under the continued use of small doses, it stimulates the various secretions, particularly that of the skin and mucous membranes. Internally, it may be given, when its aperient action is desired, with Confectio SennAe, or with* the Cream of Tartar in solution; but when its diaphoretic and alterative effects are desired, it may be given alone in milk, or in conjunction with Guaiacum, &c. Externally, it is applied in the form of simple ointment (see Offic. Prep.), or of compound ointment (Pharm. Lond.) (Sulphur iv.; White Hellebore powdered 3x.; Powdered Nitrate of Potash ij.; Soft Soap iv.; Lard lb. j.). The addition of Oil of Bergamot, xxx., to either of these ointments, conceals the objectionable odour. The Sulphur vapour-bath is, also, a valuable means for external application. The apparatus required consists of a wooden or bamboo frame, of a conical shape, covered with wax-cloth, or some other impervious material; it should be large enough to enclose the whole body (when the patient is in a sitting posture), and an aperture, with a loose frill attached, so as to tie round the patient's throat, should be left at the apex. The Sulphur is placed on a heated plate on the ground within the apparatus, and the body is exposed to the fumes for fifteen minutes, or longer. It proves highly serviceable in cutaneous, rheumatic, and some other diseases.
