OF A LIENTERY, AND ITS CURE. From a dysentery sometimes proceeds a lientery, in which the intestines can retain nothing, and whatever is taken they presently pass unconcocted. This sometimes is tedious, and sometimes carries off people quickly. Now in this disorder it is proper to administer astringents, to enable the intestines to retain. Wherefore mustard should be applied over the breast; and when the skin is ulcerated, a malagma to discharge the humour: and let the patient sit down in a decoction of the vervains; and take such food and drink as bind the belly, and have cold water poured over him. Care should be taken, however, that upon the application of all these remedies at once, there do not arise a malady on the contrary extreme by means of immoderate flatulencies. Wherefore the intestines will require to be strengthened gradually by the daily addition of somewhat. And as in every flux of the belly, so in this, it is particularly necessary to go to stool not as often as there is a motion, but as often as there is an absolute necessity, that this very delay may bring the intestines to a habit of bearing their burden. There is another direction, which belongs equally to all similar disorders, to be principally regarded in this; that since most of the things proper for the disorder are disagreeable to the palate, such as plantain, and bramble berries, and whatever is mixed with pomegranate bark, such of these are to be chosen as the patient prefers. Then if he has an aversion to them all, let something less beneficial, but more grateful, be given at times to excite his appetite. Exercise and friction are necessary also in this distemper: and with these, according to Hippocrates, the heat of the sun, the fire, the bath, and vomiting, even by white hellebore, if the other means for that purpose prove unsuccessful. CHAP. XVII. OF WORMS IN THE BELLY, AND THEIR CURE. Worms too sometimes infest the belly; and they are sometimes discharged downwards, at other times, which is more disagreeable, from the mouth: and sometimes we observe them to be broad, which are the worst kind, and sometimes round. If they are broad, a decoction of lupines, or mulberry bark in water may be given to drink: or either hyssop, or an acetabulum of pepper powdered, and a scammony with water. Or let the patient on one day, after eating plentifully of garlick, vomit; and the day following take a handful of the small stalks of the pomegranate, and boil these, after bruising them, in three sextarii of water, till a third part remains; let him add to this a little nitre, and drink it fasting: then after the interval of three hours let him take two draughts of this decoction, or the same with the addition of hard brine; then go to stool, having hot water in a vessel below him.
