Tested oil for nerve spasms in several forms.
Take 2 lb. or more of clean wax and distill it in the usual way with a glass retort. Oil will come out for use in the way described below. Put into this oil 1 ounce of mastic, 3 drams of saffron and 2 drams of camphor, all made into fine powder. When you have incorporated them, again distill it in the retort or other glass vessel. A very odorous oil will come out which you should save in a glass bottle, well closed at the top, because the gases might escape and its power would be lost. This oil has many very great virtues, especially against nerve spasm. It is powerful for every bruise, blow or kick that has clotted blood. It should be very warm when you use it and rub with it 2 times a day and keep the sore places warm with unwashed wool which is very appropriate in such a problem. While you are rubbing you will feel the pain alleviate and this comes from the soothing odor. Many experienced men have approved of it.

Another oil for spasms of nerves or from blows.
Take 1 ½ ounces each of rose oil and oil of dill, 3 ounces of Venetian turpentine, ½ bowl of earthworms washed in white wine and 1 ½ ounces each of thick pine tar and eyebright. Boil this in a little pot on a slow fire, but not too much. Then strain it carefully, pressing well so the substance comes out and it will be made. Save it for your needs and when you want to use it, put it on very warm with unwashed wool and you will be cured rapidly.

More to comfort the nerves.
Take 2 ounces each of juice of rue, oil of dill and chicken fat, 1 ounce of oil of tartar and ½ ounce of powdered mastic. Cut the fat minutely and put everything together in a carafe in the sun, well covered, for 15 to 20 days and then it will be made. Make an ointment of this. It should be warm when you use it. By continuing this, you will be cured quickly.

Another very useful oil for nerves, spasms and sores.
Take 3 lb. of the oldest olive oil that you can find, 6 ounces of malvasia wine or other good white wine and 1 handful each of flowers of camomile, sage, rosemary, wormwood and rue, cut finely. Put everything together to boil until it is reduced in half on a slow fire. Strain it and press the herbs in the press and extract all the substance by force. Return the oil to the pot and put therein ½ bowl of earthworms washed with white wine, 2 ounces each of sulfur and the white wine described above and reboil it a little. Strain it again through muslin and while it is still warm add 3 ounces of clean wax and then add 1 ½ ounce each of cloves, incense, mastic and laurel berries, all made into very fine powder, and 1 dram of saffron. Stir well with your spatula until everything is well incorporated. When you want to use it, make it warm and rub and soon you will cure, with God's grace.

Another unguent for nerves retracted and drawn up by infirmity.
Take 1 ½ lb. of earthworms washed with white wine, 1 ½ lb. of fat from the horse and 1 lb. each of bear fat, marmot fat, badger fat, oil of balsam and sweet almond oil, 5 lb. of old butter, 4 lb. of old olive oil and 1 handful each of wormwood and sage. First cut all the fats and melt them and then add in the oil and the herbs, cut minutely, with the butter and the earthworms. Boil everything for a piece. Then strain it finely under the press and extract all the substance and put it again in the pot and put therein 3 ounces of clean wax and as it melts, remove it from the fire and it will be made. Continue stirring until it is cold and it will be done. Save it for your needs for drawn and retracted nerves. It should be warm when you rub with it and put on warm unwashed wool and continue in this way and soon you will cure.
