Pycnocomon,[1] too, is a purgative. It is a plant with leaves like those of rocket, only thicker and more acrid; the root is round, of a yellow colour, and with an earthy smell. The stem is quadrangular, of a moderate length, thin, and surmounted with a flower like that of ocimum.[2] It is found growing in rough stony soils. The root, taken in doses of two denarii in hydromel, acts as a purgative upon the bowels, and effectually carries off bile and pituitous humours. The seed, taken in doses of one drachma in wine, is productive of dreams and restlessness. Capnos,[3] too, carries off bile by the urine.
