A third kind of diarrhoea is the diarrhoea biliosa. This kind of diarrhoea is a little more complicated than the two preceding varieties. It is generally occasioned by moral emotions, anger, chagrin, sometimes by catching cold in hot and damp weather; this frequently makes it an endemic or epidemic disease. Its accompanying symptoms are: want of appetite, bitter taste, yellowish complexion, coating of yellow mucus on the tongue, bitter and disagreeably sour eructations, aversion to food, nausea, and sometimes vomiting of bile; the evacuations are bilious, yellow, green, and are accompanied with violent colic. The diarrhoea from dentition is sometimes characterized by similar symptoms; in this case the sour-smelling, 10 greenish stools do not always depend upon an effusion of bile, but upon acidity in the primae vise; they frequently have a chopped appearance or look like stirred eggs; in some cases the anus is corroded by the stools.

The remedies for bilious diarrhoea are the same which have been indicated § 40, and the following. The diarrhoea which is occasioned by acidity in the primae viae, and is most frequently met with in children, is cured by Chamomile or Rheum. Sometimes such a sour-smelling diarrhoea becomes chronic; in such a case Magnes. carb. will remove the trouble in a very short while. If the anus, genital organs, and inner surface of the thigh should be very sore, and if the whole body, but especially the thighs, should be covered with a miliary eruption, Sulphur is the best remedy. If the children should be still at the breast, the dose had better be given to the mother or nurse, recommending a strict homoeopathic diet. This diet is likewise necessary, when the child is brought up without the breast or is already weaned. In very many cases the little being is stuffed with pernicious things or an excessive quantity of food, pap, etc., to keep it quiet. In cases where Chamomilla is indicated, the physician ought to inquire very carefully whether Chamomile-tea had been given; for the diarrhoea frequently arises from an abuse of that drug. In that case the symptoms ought to be antidoted by Coffea or Pulsatilla before another remedy is given.

Besides the remedies already mentioned we refer to Mercurius, Hepar sulp., Sepia, Calcarea, and Graphites. We have seen this diarrhoea in children several times, who looked like a piece of raw flesh all over the body, lamented a good deal at night, and were prevented from sleeping by the pain. This condition depends generally, but not exclusively, upon syphilis in the parents. There is no better remedy for that group of symptoms than Mercurius; this either effects a cure or modifies the symptoms so that they will yield to Hepar s., Sulp., or Graphites.

The remedies which we have indicated in the preceding paragraphs, but especially Calcarea, are especially adapted to such diarrhoeas when occurring in scrofulous patients; the secondary symptoms, which, however, are not always very prominent, will point more distinctly to one or the other of those remedies.

A fourth class of diarrhoea is the diarrhoea mucosa, pituitosa. This diarrhoea sometimes arises from a mismanaged watery or feculent diarrhoea. Or it may be occasioned by a cold in damp, wet and cold fall-weather, and in low and marshy regions; when such causes prevail, the diarrhoea may become epidemic or endemic. Weakly, nervous, dyspectic persons are most easily affected. The disease is ushered in by distention and hardness of the abdomen, pressure and feeling of repletion in the abdomen, flatulence, loss of appetite, slimy coating of the tongue, etc. The discharges have various colours, generally they are slimy, and sometimes streaked with blood. They are debilitating, and induce emaciation unless soon arrested. This kind of diarrhoea is, in most instances, a consequence of existing affections, especially of mucous fevers.

As a general rule, mucous diarrhoeas are treated like mucous fevers. It is a remarkable fact that such diarrhoeas, together with their accompanying symptoms, generally correspond to Pulsatilla, especially if the colour of the stools vary. If the diarrhoea should be greatly debilitating, Colocynthis may be given. If the evacuations should be slimy, green, sanguineous, accompanied by tenesmus, Merc. sol. is the remedy. If the disease should be one of long standing, Petroleum will sometimes cure it, provided it corresponds to the secondary symptoms; Acidum phosp. or Phosporous are sometimes the best remedies. According to Dr. Gross, the best remedy in painless diarrhoea is Ferrum metallicum. Lately Secale cornutum has been frequently given for mucous diarrhoea, especially when the tongue was coated with mucus, and the patient complained of papescent taste and rumbling in the abdomen. It may be remarked that all those remedies have to be given repeatedly.

We do not speak of diarrhoea verminosa, diarrhoea sanguinea, diarrhoea urinalis, and diarrhoea purulenta; these are secondary affections which have to be treated in company with the primary disease.

Slimy kinds of food and drink, such as sago, salep, rice, vermicelli, gruel, barley, oatmeal, etc., are to be recommended in this kind of diarrhoea; if the diarrhoea be chronic and yield only for a few days to the remedies which are given for it, the patient may eat whortleberries, either raw, dried, or stewed. Fresh-drawn milk, not boiled, is an invaluable remedy for diarrhoea of children which does not yield to medicine.
