[English translation]

To cure breasts that may have broken open from a humor or an ulcerated abcess that may discharge matter.
Take roots of the herb that is called dropwort which has leaves that draw back like those of burnet saxifrage and has white flowers like those of wild carrot but a little larger and has roots that grow like those of peony but smaller and all attached one behind the other in the shape of a ring. The time to pick it is in the beginning of June when it is blossoming perfectly. Take as much of this root as you wish, wash it well and dry it in the shade if you can and make very fine powder of it. Save this for all your needs. When the woman has an illness in the breast caused by running humors she may have pain more in one place than another and if you see some signs of red and hard swelling there may be an opening from which material continues to leak out. So that this woman may be cured rapidly, do this. Every morning take ½ spoonful and not more of this powder and have her drink it with white wine or warm broth as a syrup early in the morning and she should rest for an hour. If the breast is not broken open, do nothing more. Rub only with violet oil and if the soreness is increasing it will break open by itself and if the abcess is small it will be resolved from within. If the breast has broken open and matter leaks out, do not put anything on it except 3 or 4 folds of white cloth, one on the other, because this powder has the property that by itself the medicine cleans all the matter inside and sends it out through the opening and gently cleans without pain. When a lot of matter comes out that is a good sign that it is curing quickly because all the matter is gathering and coming out. Then, so that this illness will be well healed, she should follow all the rules you give her and it will heal easily and well. Even if the breast was swollen but it came to a head that was not broken open, continue just the same with this powder alone and the illness will be resolved little by little. You need to do nothing more. She should take care of herself for a few days and will be cured. It is tested. This powder is also useful in epilepsy.
If you take the flowers of dropwort that are white and put them in a little carafe with pure olive oil and cover it and put it in the sun for 20 days or one month, the oil will take on a very wonderful and pungent odor. This oil has many virtues, especially for pain of the stomach and also for those who may be ill from pregnancy and if it is rubbed on warm it is powerful in pains of the body. It stimulates urine and it may cure leaking of urine. It is useful for pain in the kidneys and it removes flatulence from the stomach, when it is rubbed on very warm. It removes the burning and signs of a burn and leaves the flesh soft. This oil has been tested many, many times by many gentlewomen of the Piedmont.... 98
