As to pelorides,[265] they act as a gentle laxative upon the bowels, an effect equally produced by castoreum, taken in doses of two drachmæ, in hydromel: where, however, a more drastic purgative is required, one drachma of dried garden-cucumber root is added, and two drachmæ of aphronitrum.[266] The tethea[267] is good for griping pains in the bowels and for attacks of flatulency: they are generally found adhering to the leaves of marine plants, sucking their nutriment therefrom, and may be rather looked upon as a sort of fungus than as a fish. They are useful, also, for the removal of tenesmus and of diseases of the kidneys. There grows also in the sea a kind of absinthium, known by some persons as “seriphum,”[268] and found in the vicinity of Taposiris,[269] in Egypt, more particularly. It is of a more slender form than the land absinthium, acts as a purgative upon the bowels, and effectually removes intestinal worms. The sæpia, too, is a laxative; for which purpose these fish are administered[270] with the food, boiled with a mixture of oil, salt, and meal. Salted mænæ,[271] applied with bull’s gall to the navel, acts as a purgative upon the bowels. The liquor of fish, boiled in the saucepan with lettuces, dispels tenesmus. River-crabs,[272] beaten up and taken with water, act astringently upon the bowels, and they have a diuretic effect, if taken with white wine. Deprived of the legs, and taken in doses of three oboli with myrrh and iris, one drachma of each, they disperse urinary calculi. For the cure of the iliac passion and of attacks of flatulency, castoreum[273] should be taken, with seed of daucus[274] and of parsley, a pinch in three fingers of each, the whole being mixed with four cyathi of warm honied wine. Griping pains in the bowels should be treated with castoreum and a mixture of dill and wine. The fish called “erythinus,”[275] used as food, acts astringently upon the bowels. Dysentery is cured by taking frogs boiled with squills, and prepared in the form of boluses, or else hearts of frogs beaten up with honey, as Niceratus[276] recommends. For the cure of jaundice, salt fish should be taken with pepper, the patient abstaining from all other kinds of meat.
