CHAP. 66.—PTISAN: FOUR REMEDIES.
To ptisan,2782 which is a preparation of barley, Hippocrates2783 has devoted a whole treatise; praises, however, which at the present day are all transferred to “alica,” being, as it is, a much more wholesome preparation. Hippocrates, however, recommends it as a pottage, for the comparative ease with which, from its lubricous nature, it is swallowed; as also, because it allays thirst, never swells in the stomach, passes easily through the intestines, and is the only food that admits of being given twice a-day in fever, at least to patients who are in the habit of taking two meals—so opposed is his method to that of those physicians who are for famishing their patients. He forbids it to be given, however, without being first strained; for no part, he says, of the ptisan, except the water,2784 should be used. He says, too, that it must never be taken while the feet are cold, and, indeed, that no drink of any kind should be taken then. With wheat a more viscous kind of ptisan is made, which is found to be still more efficacious for ulcerations of the trachea.
