Give roots of ragweed tempered by subtle wine, or with good broth, at the end of the day, to him who is tired after walking, and the fatigue will go from him, as though it had never been—so says Dioscorides. And whoever goes a journey, if he carry a staff of tutsan101 he will not stumble against a stone, or anything else, nor will walker's abrasion (?)102 seize him; and if it do, he need only rub on oil of roses, or the yolks of eggs, raw or heated. This is useful for friars, who walk the country, or the people of pilgrimage, or for envoys, according to Serapion.
