Phthiriasis is a disease which proved fatal to the Dictator Sylla,[1] 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 grapes[2] 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.
