97. Crocus: i.e. saffron; it is hot and dry in the first degree; it has the virtue of comforting the heart and the brain; if it be kept in a clean place, such as a clean white leather satchel, it will retain its efficacy for six years. Ysaac says that it both comforts and weakens the stomach. The stomach is comforted by it as follows, when it is taken on an empty stomach, and the stomach is weakened by it when it is taken when the stomach is full. Item, take saffron finely pounded and mix with the yolk of an egg, dip cotton in it, put it over the eyes, and it will help with their redness and their pain. Platearius says there are two sorts of saffron, the garden sort and the Eastern sort. The garden sort is the saffron that is produced in gardens. The Eastern sort is the sort that is obtained otherwise than in gardens; saffron that is not quite red is bad, especially when it is of a yellow colour, and the redder it is the better, and the more it is to be recommended for everything that we have mentioned. Item, Platearius says whoever uses too much saffron suffers nausea; it should not be given to choleric people because it provokes vomitting in the case of that complexion; it serves well against stranguria, colic and ileus.
