There are also some remedies, recommended with the intention of absorbing acrimonious excretions; such as, flour or magnesia, in erysipelas. But these seem to act entirely by allowing the action to run its course, without interruption, affording a softer defence than could otherwise be obtained. From the quick progress of violent cuticular inflammation, the applications which are usually made in other inflammations have been forbid here, and are said to be pernicious; but this rather appears to arise from the application not being properly timed, than from any peculiarity in the disease. It is not easy to give any good reason why cold saturnine solution, of a proper weakness[18], and sufficiently early applied, should not be useful; nor do we find, that they are in reality hurtful in simple erythema. Where this, however, attends wounds, or is not an original disease, these are improper; because it is in general, in these cases, an attendant upon the inflammatio debilis, or a symptom of it, and requires either to be let alone, or to have stimulating applications made to it, at the same time that we give bark internally[19].

These remarks upon the resolution of the inflammatio valida, may be concluded, by observing, that the diet ought to be low and sparing, in a degree proportioned to the violence of the action. Such motion as affects the local action, must at all times be prevented; but when a general action likewise exists, then general quietude must also be insisted on.

Of the Remedies which are necessary for inducing Suppuration.

Suppuration is a new action, the exciting cause of which is inflammation; but, that it may take place, it is requisite, that the inflammatory action be prevented from subsiding too soon, or too suddenly; in which case, either resolution, or inflammatio assuefacta, takes place: Whilst, on the other hand, we must prevent the action from rising too high, and proceeding too rapidly; in which case, mortification is caused.

In these cases, in which resolution cannot be obtained, suppuration will generally take place, without any interference on our part, provided we prevent the action from terminating in gangrene. This we observe in many internal inflammations. At the same time, we may sometimes accelerate this process, by a proper regulation of the original action.

The remedies proper for moderating and removing the inflammatory action, have been already mentioned; but these sometimes fail to produce resolution; in which case, either suppuration, or mortification, take place. When the symptoms of suppuration take place (which have been already noticed), all that is perhaps essentially necessary, is, to give up the resolving plan, and not interrupt the natural progress of the action. If, however, the inflammatory action continue longer stationary, and seem neither to be resolving, nor decidedly inducing the suppurative action, then such remedies as increase the action, and accelerate its progress, are essentially requisite. These remedies, however, are, in general, indiscriminately applied in both cases.

For the purpose of inducing, or accelerating the suppurative action, it was formerly the practice to apply liniments, cataplasms, and fomentations, composed of stimulating substances, such as garlic, turpentine, galbanum, &c.; but of late these have been almost entirely abandoned. Heat and electricity have the property of increasing the performance of every action which is existing at the time of their application, and, therefore, are the remedies chiefly to be employed in the present instance.

Heat may be applied in two ways, with or without moisture. In the first, it increases action more suddenly, and perhaps more simply. In the second, its effects are more gradual, and are likewise complicated with those of moisture, which certainly is an agent capable of operating on the living system, and generally tends to excite a secretory action, or to give a secretory termination to those increased actions, which are induced by agents operating alongst with it. Dry heat is therefore evidently improper in the inflammatio valida, because it will tend to produce mortification; but, if moisture be conjoined, then the suppurative action is excited. When, however, the action has made an approach to the inflammatio assuefacta, then it may be useful to raise the action simply by dry heat, for a little, before we apply heat and moisture; because, if we apply moisture at first, the progress is more tedious, and the action is less certainly excited[20]. Electricity is similar in its operation to heat and dryness, and may be usefully employed in similar cases; but we must, if we expect any benefit, repeat its operation frequently, and continue each application for a considerable time[21].

There are two forms in which we employ heat and moisture, namely, fomentations and poultices. Fomentations[22] have this superiority over poultices, that the same degree of heat is always kept up during their application; whereas, when we use poultices, the heat subsides, as they are renewed only at considerable intervals; but fomentations require longer attendance, and more trouble; and, therefore, are only employed for a short time, and commonly betwixt the intervals at renewing the poultices.
