CHAP. III. OF THE SYCOSIS.
There is an ulcer, which from its resemblance to a fig, by the Greeks, is called sycosis[ FQ ], because flesh sprouts up from it. And this is the general name. Under it are included two species. The one is a hard and round ulcer; the other is moist and unequal in its surface. From the hard one the discharge is very small and glutinous; from the moist, it is in greater quantity and fetid. Both kinds occur in the parts covered with hair: but that which is callous and round, most frequently in the beard; the other, which is moist, chiefly in the hair of the head.
To both of them it is proper to apply elaterium, or lintseed powdered, and made into a paste with water, or a fig boiled in water, or the tetrapharmacum plaister softened with vinegar. Eretrian earth also liquified with vinegar is proper to lay upon them.
