Oil made of rosemary flowers with its tested virtues.
Take the oldest olive oil that you can find in whatever amount you have and take as many rosemary flowers as you have and put them in the oil and let them stay for 2 days in a warm place or in the sun in a covered vessel. Then take some pieces of brick or of earthenware jars that are new and have not touched water and heat them very hot. Put them to cool down in the oil with the flowers. Then remove them from the oil and grind them finely in a mortar so that nothing is lost. Put everything together, the powdered brick, the flowers and what is left of the oil. Distill everything on a slow fire into a glass flask, following the usual method, and do this with skill. Save this blessed liquor in glass, well stoppered, and cherish it because we will say below some of its virtues, viz.
The virtues of the oil made with rosemary flowers.
Here we will deal with some virtues of the oil of rosemary made with flowers as you should have learned to make it above. First it is powerful to remove cold from all the members chilled through some accident to the head, the hands, the feet and the chest, if the place is rubbed with the very warm oil.

Another.
It is powerful for all the cracks in the feet and hands caused by cold, especially for use in the wintertime when they usually come.

Another.
It is powerful to heal all the sores of the flesh in every place on the body, even for any animal, by rubbing with very warm oil.

Another.
It is effective in rewarming every chilled nerve in whichever place on the human body or of other animals, through cold gout or other causes of cold. One of the many powers that it has is that the tremor of the hands or head that occurs through great coldness is diminished by the heat it develops. It is very powerful against cold.

Another.
It is very powerful for those who have lost hands or feet through cold who have not been helped very well, that is to say for those who have damaged the neck and the nerves of any limb through cutting or bad medication.

Another.
It is powerful for those who have gout, who are not able to walk because of this infirmity or are not able to support themselves on their feet when this has happened through chilling of the nerves.

Another.
It is powerful for those who have a stiff neck or sore throat and who, through natural causes, are not able to turn the head well.

Another.
It is powerful against kidney and bladder stones, By drinking the oil and rubbing it warm on the neighboring parts, it corrodes them and breaks them, turning them into gravel which is purged through the meatus in the usual way. It is powerful for cleaning the bladder inside and out. You should know that when the gravel moves, it stings. .

Another.
It is powerful when urine flow is suppressed. Drinking a little of it provokes a great quantity of urine in one in whom it is reduced by stricture of the meatus and in one who is able to urinate only with much difficulty.

Another.
It is powerful for each inflamed and swollen limb or head or forehead, that is for one who has what is called the French sickness or by other names.

Another.
It is powerful for every distress in hearing, which comes from every kind of great coldness and flux of these bad humors with sharp pains and deafness.

It is powerful in paralysis and in every joint pain including the joints of the fingers, hands and feet.

Another.
It is powerful for torsion of the mouth caused by plague when it is used as an ointment and also when it is drunk.
