Phthiriasis is a disease which proved fatal to the Dictator Sylla,1508 and which developes itself by the production of insects in the blood, which ultimately consume the body. It is combated by using the juice of Taminian grapes1509 or of hellebore, the body being rubbed all over with it, in combination with oil. A decoction of Taminian grapes in vinegar, has the effect, also, of ridding the clothes of these vermin.
