The disease called "tenesmus," or in other words, a frequent and ineffectual desire to go to stool, is removed by drinking asses' milk or cows' milk. The various kinds of tapewormn[1] are expelled by taking the ashes of deer's horns in drink. The bones which we have spoken[2] of as being found in the excrements of the wolf, worn attached to the arm, are curative of diseases of the colon, provided they have not been allowed to touch the ground. Polea, too, a substance already mentioned,[3] is remarkably useful for this purpose, boiled in grape juice:[4] the same too with swine's dung, powdered and mixed with cummin, in a decoction of rue. The antler of a young stag, reduced to ashes and taken in wine, mixed with African snails, crushed with the shells on, is considered a very, useful remedy.
