UNGUENTUM SULPHURIS--SULPHUR OINTMENT

Composed of washed sulphur, 150; benzoinated lard, 850.

ACTIONS.--Sulphur applied to skin or mucous surfaces is a feeble,

mechanical stimulant, and hence relieves chronic passive congestion. It

destroys parasitic infestation of the skin. Administered internally it

is a laxative and alterative. It destroys fungi on vines and kills

similar parasites affecting plants and animals. How much of this toxic

effect depends on the sulphur acting as sulphur, and how much on the

alkaline sulphides, sulphuretted hydrogen and sulphurous acid into which

it is gradually converted, has not been determined. Sulphur when

swallowed is slowly acted upon by the alkaline secretions of the

intestines, and small quantities are converted into sulphides, which

stimulate the intestinal mucous membrane. A further change liberates

sulphuretted hydrogen, which imparts its disagreeable smell to the

breath, secretions of the skin and bowels. The greater part of the

sulphur swallowed is removed unchanged by the bowels, but a portion is

excreted in the urine as sulphates. Over-doses given to horses and other

animals cause colic, purging, prostration and sometime fatal

gastro-enteritis.

USES.--Sulphur is given to the several domestic animals as a laxative

where more powerful purgatives might irritate--as in pregnancy,

convalescence from acute diseases in young animals, and in piles.

Its alterative and stimulant effects on the skin have led to its use in

rheumatism, eczema and cutaneous diseases. Some veterinarians affirm

that it benefits dry congested conditions of the respiratory membrane by

stimulating its epithelial cells and increasing movements of the cilia.

It has no special vermicide action. Sulphur dusted on the skin slightly

stimulates, but when dissolved by admixture with an alkali or oil, and

smartly rubbed in, it more actively stimulates the cells of the rete

Malpighi and thus hastens desquamation; while it also increases

contractility of the muscular textures, and hence overcomes passive

cutaneous hyperaemia. It thus promotes a healthier action in chronic

eczema and psoriasis, and in such cases sulphur dressings are used with

benefit combined or alternated with iodine or tar acids, and are aided

by the internal use of sulphur and arsenic. Infriction of sulphur

ointment is stated to relieve the pain of rheumatic muscles and joints.

Sulphurous gas from burning sulphur is used for husk or hoose of sheep

and calves; this is a disease in which worms affect the bronchial tubes,

due to strongylus micrurus in calves and strongylus filaria in sheep.

The patients are placed in a loose box and sulphur is burned about six

feet away from them, so that air may dilute the fumes before being

inhaled by the animals; let them inhale the fumes for ten or twenty

minutes or longer, unless irritation is too great.
