The absorbent earths are a more useful remedy in this form of the disease. They have, perhaps, a restringent effect independent of their power of absorbing acid. It is certain, however, that great part of their use consists in the destruction of acid, which is very apt to be generated in that depraved state of digestion which takes place in advanced fluxes, particularly in this lienteric state of the bowels. In the early and acute state the vegetable purgatives, such as cream of tartar, tamarinds, and manna, are proper; but in this advanced stage they are hurtful by the acidity and flatulence which they produce, and both the food and medicines should be so calculated as to avert and correct those inconveniencies. There is something in vegetable acids extremely unfriendly to a weak state of the bowels in general, tending to bring on spasmodic gripings, and preventing a healthy digestion and assimilation, as we know in the case of heartburn, and of those who make use of vinegar to check corpulency, by preventing the formation of blood. Vegetable acids, however, are admissible where there is a redundancy of bile, or where the excrements are putrid; and Dr. Zimmerman recommends tamarinds as a useful medicine in what he calls the putrid dysentery. Lime water has been recommended in old flaxes, and I tried it in several cases; but, except in one, I could not perceive any benefit from it. Absorbents may very properly be combined in prescription with some of the compound-officinal opiates, and a medicine will thereby be formed, which will have at once the advantage of an anodyne, a bitter, an astringent, a carminative, and absorbent. As these earths have little or no taste, they may also be added, with propriety, to the common drink, as in the form of the chalk julep, or _decoctum album_. It may be thought that here and elsewhere I have not been so particular as I ought to be concerning the forms and doses of medicines; but circumstances, such as age, constitution, and symptoms, make these, in a great measure, discretionary; and any one who is sufficiently conversant with physic to be entrusted with the charge of the sick, will have sufficient judgement to vary his practice accordingly. It has, therefore been my object rather to give the general principles of treatment than the particular forms of medicines.
