Nymphæa heraclia, used as already stated,1309 acts most powerfully as an antaphrodisiac; the same too if taken once every forty days in drink. Taken in drink fasting, or eaten with the food, it effectually prevents the recurrence of libidinous dreams. The root too, used in the form of a liniment and applied to the generative organs, not only represses all prurient desires, but arrests the seminal secretions as well; for which reason, it is said to have a tendency to make flesh and to improve the voice.1310

The upper part of the root of xiphion,1311 taken in wine, acts as an aphrodisiac. The same is the case too with the wild crethmos,1312 or agrios as it is called, and with horminum,1313 beaten up with polenta.1314
