34. Antera, flos rose: i.e. the flower of the rose; it is cold in the first degree and dry in the second degree; make a plaster of it and put it on erysipelas and it will help with it; the same plaster will help with the boiling and heat of the entrance of the stomach; if rose be boiled in water and pounded, and white of egg put through it, and it be placed as a plaster on the eyes, it will help with the heat and redness of the eyes; if it be boiled in wine it will prevent the flux of the abdomen (diarrhoea) and of menstruation. The water of rose will serve against every excessive heat. Rhases says to make a plaster of fresh rose, and it will help with every swelling that comes either naturally or accidentally. Note that, according to Platearius, when it is taken dried it has the constricting virtue, and when taken fresh it has the laxative virtue, and the virtue of purging the choleric humour, especially when it is mixed with rhubarb. Platearius says that of this is made rose honey, rose water, rose sugar, and rose syrup. These manufactures serve well against the hot illnesses, and against headache and pain of the temples, like rose oil, and it serves against hectic fever and fainting, against flux of the abdomen, and against the vomiting caused by the choleric humour; the brain and the heart are comforted by these manufactures; they serve against the wetness of the uvula, and to expel the quartan fever. Macer says to make powder of the red rose and put it in the ulcers, and it will clean them of their exudation; if the same flower be put on a burn of fire or water with white of egg, the burn will not go bad.
