COMMON CATARRH AND EPIDEMIC INFLUENZA.
The seat of the disease is in the mucous membrane, which is a continuation of the external skin, folded into all the orifices of the body, as the mouth, eyes, nose, ears, lungs, stomach, intestines and bladder; its structure of arterial capillaries, veins, arteries, nerves, &c., is similar to the external skin; its most extensive surfaces are those of the lungs and intestines, the former of which is supposed to be greater than the whole external surface of the body.
The healthy office of this membrane is to furnish from the blood a fluid called mucus, to lubricate its own surface, and protect it from the action of materials taken into the system. The mucous membrane and the external surface of the body seem to be a counterpart of each other, and perform nearly the same offices; hence, if the action of one is suppressed, the other commences the performance of its office; thus a cold which closes the skin immediately stops the perspiration, which is now forced through the mucous membrane, producing the discharge of watery humors, pus intermixed with blood, dry cough, emaciation, &c. There are two varieties of this disease; the first is called common catarrh, which proceeds from cold taken in pasture that is not properly drained, also from atmospheric changes; it may also proceed from acrid or other irritating effluvia inhaled in the air, or from poisonous substances taken in the stomach in the form of food. The second variety is called epidemic influenza, and is produced by general causes; the attack is sometimes sudden; although of nearly the same nature as the first form, it is more obstinate, and the treatment must be more energetic. It is very difficult to lay down correct rules for the treatment of this malady, under its different forms and stages. The principal object to be kept in view is, to equalize the circulation, remove the irritating causes from the organs affected, and restore the tone of the system.
For this purpose, we make use of the following articles:—
Mix, pour on the whole one quart of boiling water, set it aside for two hours, then strain through cotton cloth, and give a table-spoonful night and morning.[20] If the bowels are constipated, a dose of linseed oil should precede the mixture. No water should be allowed during the treatment.
The following injection may be used:—
| Powdered bayberry bark, | 1 ounce. |
| Powdered gum arabic, | half an ounce. |
| Boiling water, | 1 pint. |
Stir occasionally while cooling, and strain as above.
The legs and ears should be briskly rubbed with tincture of capsicum; this latter acts as a counter-irritant, equalizes the circulation, and, entering into the system, gives tone and vigor to the whole animal economy.
