Celsus treats of _morbus cardiacus_ after phrenitis, because, as he says, persons affected with phrenitis are apt to fall into the other. He calls it a great weakness of the body, which, owing to the languid state of the stomach, is melted by immoderate sweating. It is recognized by a small and weak pulse, immoderate sweats, breaking out from the chest and neck, the feet and legs alone being dry and cold. He adds, it is a sort of acute disease. His treatment consists in applying a repressing cataplasm to the præcordia, and next, in stopping the sweats by friction with sour oil, roses, &c., or with some cerate similarly prepared. If the sweating gains ground, the body is to be anointed with parget, litharge, Cimolian earth, or sprinkled with the powder of them. The patient is to be lightly covered, laid in a place not too warm, with open windows, so that a current of air may reach him. Light food is to be frequently administered, and also, if necessary, wine neither too strong nor too weak, which may be given with barley-meal, if the patient has not taken other food. If he cannot take food, he is to be first treated with the affusion of cold water; and if his stomach have lost its tone, he is to be allowed to vomit before taking food. If the stomach still reject the food, he is first to take a cupful of wine, which is to be repeated after an hour, and then the whole body is to be anointed with pounded bulbi (onions?), which will have the effect of making the stomach retain the wine, and thereby heat will be restored to the whole body and strength to the veins. As a last resource, he recommends an injection of ptisan or gruel. Fragrant things may also be applied to the nose, such as roses and wine; and if the extremities be cold, they are to be chafed with hot hands smeared with oil. If the violence of the sweating be thus checked, and life prolonged, the time thus gained will be of some assistance. Means are afterwards to be taken to prevent a relapse. (iii, 19.)
