"[Plin. Nat. 27.29.] - ABSINTHIUM: MARINUM OR SERIPHUM.
There is a sea wormwood also, known as "seriphum" by some, the most esteemed being that of Taposiris in Egypt. Those initiated in the mysteries of Isis carry a branch of it in the hand. It has a narrower leaf than the preceding plant, and is not so bitter; it is injurious to the stomach, has a laxative effect upon the bowels, and expels intestinal worms. It is taken in drink with oil and salt; or else an infusion of it is taken in a pottage made of meal of three-month wheat. When employed as a decoction, a handful is used to one sextarius of water, the mixture being boiled down to one half. ”
