All hot medicines are alfo prejudicial, and the common uterine elixirs, with the diffcillcd oils, and volatile falts, are liable to the fame objections. Some give the com- mon tcrreftrial alkalies and abforbents, but they give no relief in thefe cafes ; becaufe an acid either is no caufe, or, at the utmoft, is not the eflential caufe of thefe diforders. Steel medicines are alfo given by many; but they are to be ufed with great caution ; and, in general, they fcldom do any good, but very often a great deal of harm. As there are, hawever, fome cafes of this kind in which they excel all other medicines, it is always proper to give them a fair trial, under the proper regulations.
The common chalybeate waters often prove of more fervice in this difeafe than all the medicines in the world ; but they are to be taken with the proper cautions, and a due regimen. It is neceflary to bleed in the foot before entering on a courfe of them, and then they are to be drank in moderate quantities, and always a little warmed, ufing a moderate exerc'tfe during the time of drinking them.
