In the taking away of Warts, this Spirit is to be mixed with the juice of Marigolds, and applied to them: It also taketh away Corns, if after they are softened with warm water, they be well cut and anointed with this Oil. In the Erysipelas, St. Anthony’s fire, this being mixed with Elder-Vinegar, and applied, is of great virtue.
The Hands or Feet being corrupted or chapt by Cold, are recovered by the benefit of this Medicine. This Spirit or Oil greatly conduceth to help the weariness and weakness of the Feet and other Members, restoring to them their strength and vigour, if they be well bathed therewith before the fire.
Moreover, in the dolorous Gout it is a famous Remedy, and a profitable Anodine for allaying the pain, if besides its internal use it be also applied topically: For to this our Medicine are to be joined Oil of Turpentine, Oil of Wax, Oil of Camomile, or also Oil of Cowslips, with which the parts affected are to be well anointed. But where the members are contracted by Fluxions and Catarrhs, fit Fomentations are also to be used, and besides our Oil or Spirit, the dulcified Oil of Vitriol, and pure Oil of Turpentine, are to be mixed together, and the parts to be therewith anointed before the fire. And hence the Nerves and Joints are so comforted, that they will not so easily admit such Fluxions again. Also if there be Tophes or Nodes in the Joints, they will be discussed beyond belief; being duly anointed with this Oil, mixed with the dulcified Oil of Vitriol.
It is also used with great profit both inwardly and outwardly, against the Cramp and Convulsion of the Nerves by Cold.
In external Wounds and Symptoms there often happens a Putretude, and also proud Flesh sometimes starteth up, and causeth great pain. These Protuberances being anointed with this Oil or Spirit, are presently dissolved and consumed, and also preserved from future corruptions.
In brief, this is a most excellent Medicine, overcoming many Diseases. Moreover, the Reader is to know, that this spirit or Oil of Salt, (besides those Virtues which I have declared) if it be diligently prepared, and rightly prescribed, may be used for the preparing of many excellent and precious things in the Chymical Art; for it dissolveth Gold, Gemms, and other Stones, Pearls, Corals, &c. so that they are reduced into excellent Medicines, in a liquid or potable form, highly useful for Mankind: But how those Processes are to be instituted, I shall here pretermit, But he that hath drawn a good foundation of working from that information which my Medulla Destillatoria hath faithfully propounded, let him weigh the matter with an accurate mind, and put his hand to the Work, there is nothing in it so tedious, but he will easily conceive; moreover, let him associate himself with honest, sincere, and skilful Artists, and take their counsel, then he will find out many Secrets of Nature, and singular Arcana’s, and will see that his care and diligence hath not been in vain: Then let him use that Experience to the Glory of God, and the help of his needy Neighbour.
The Virtues or most efficacious Operations of the Spirit or Oil of Salt, in which Gold is rightly dissolved, according to Art; or, when it shall be made an Aurum Potabile.
Philosophers and Physicians, endowed with the great Exercise and Knowledge of Things, have attributed to the Spirit or Oil of Salt, in which Gold is rightly dissolved, or the Aurum Potabile made with it, very great operations in the body of Man, inasmuch as in all Diseases and Infirmities, of what name soever, it giveth present help, and in all dejections of the vital spirit, although they tend to the fatal period, it giveth such relief, that life and vigour may be yet somewhat farther protracted, if two, three, or four drops be administred as occasion shall serve in a good Aqua vitæ or Cordial Water. In like manner, if three drops be administred once a week in generous Wine, or Aqua vitæ, or other fit Vehicle, it renovateth a man, makes him youthful, changeth gray Hairs, produceth new Nails, and Skin, preserveth from various and diverse symptoms of Diseases, and preserveth the body in such a state, even to the prefixed hour of the Divine appointment.
These are the very words of that famous Philosopher and Chymical Physician Conradus Kunrath, in his Medulla Destillatoria; as the Reader may there see.
