Sweating, considered as a mean of abating general action, is, in most cases, inferior to bleeding; and can never, when the general inflammatory action is considerable, be trusted to alone; but, after the use of the lancet, it is generally serviceable. It is useful, in particular, when the local disease is not confined to a small spot, but affects a considerable surface, or different parts of the body; as, for instance, in the rheumatism; but it acts, in these cases, rather by the sympathy of equilibrium, than by any other mode. At the same time, the induction of a sweat, preceded by bleeding, (which tends to abate the local action as well as the general one) will sometimes be useful, by giving a secretory termination to the general disease, and hastening its conclusion. In the first point of view, sweating may be used early in the disease, especially if preceded by bleeding. In the second, it will be chiefly useful toward the end, as it will then accelerate the termination, and thus influence the local action; for the abatement of the general action must also produce an abatement of the action of a particular part. Sweating, as well as purging, must be used with caution in weakly people, or in those who are reduced by disease; because, although the action of particular parts may be increased by it, yet, partly in consequence of this temporary increase, and partly on account of the fluid which is discharged, general weakness is induced. One of the best sudorifics is the pulvis ipecacuanhæ comp.; of which we may give ten grains every hour, until sweating be produced, giving warm lemonade alongst with it. The tartar emetic is also a very useful sudorific; the sixth part of a grain may be given every half hour, until the proper effect be produced[7]. [7] One grain of emetic tartar may be dissolved in five ounces of saline julep, and a table spoonful given every half hour, as long as may be necessary. Some of the agentes dissimiles may be considered as proper remedies in this complaint; such as, digitalis, laurel water, lead, &c.; But they are certainly inferior to blood-letting; and have been so little employed in this way, that their effects are not ascertained[8]. [8] Some of these agents might perhaps only change the nature of the inflammation, and render it specific.
