Chalcetum[1] also is the name of a plant, which is pounded with grape husks and applied topically, for the cure of liver complaints. Root of betony acts as a gentle emetic, taken in the same way as hellebore, in doses of four drachmæ in raisin wine or honied wine. Hyssop, too, is beaten up with honey for similar purposes; but it is more efficacious if nasturtium or irio[2] is taken first.

Molemonium[3] is used as an emetic, being taken in doses of one denarius; the same, too, with sillybum.[4] Both of these plants have a milky juice, which thickens like gum, and is taken with honey in the proportions above-mentioned, being particularly good for carrying off bile. On the other hand, vomiting is arrested by the use of wild cummin or powdered betony, taken in water. Crudities and distaste for food are dispelled, and the digestion promoted by employing daucus,[5] powdered betony[6] taken in hydromel, or else plantago boiled like greens. Hiccup is arrested by taking hemionium[7] or aristolochia,[8] and asthma by the use of clymenus.[9] For pleurisy and peripneumony, the greater centaury is used, or else hyssop, taken in drink. Juice of peucedanum[10] is also good for pleurisy.
