Pycnocomon,1182 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.1183 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,1184 too, carries off bile by the urine.
