The Chemical Writings of Brother Basilius Valentinus: The Treatises of Heinrich Eschenreuter

Onto the residue, pour again as much urine original symbol: 🜬; urine was frequently used in alchemical medicine as a source of volatile salts and ammonia. as before, place it once more in the digestion oven original: Diger. Of.; a furnace used for prolonged, gentle heating to break down substances. and let it stand for twenty-four days and nights. Then you will see that it becomes blood-red again. You may filter it and pour it together with the previous liquid, and use the remaining residue for fresh wounds. Put the filtered urine into a large glass flask, or a retort vessel that is well-glazed on the inside, and let the urine rise over i.e., distill very gently, until the residue becomes entirely dry. There will remain behind a clear, gold-yellow key original symbol: 🗝, Clavis; in alchemy, a 'key' is a fundamental substance or agent used to unlock the virtues of a mineral. like saffron.

(Note: With this key is a double salt original symbol: ⊖, Sal Duplicatum; a salt formed by the combination of two different salts, here an acid and an alkali. which comes from the acid and alkali original: Acido & Alcali and passed through during filtration, for it dissolves in all solvents original: Menstruis. This is the true remedy against scurvy original: Antiscorbuticum joined with the red cordial tincture of coral original: cordiali Tinctura rub. Cor.; "Cor." likely refers to Corallorum (coral), a substance believed to strengthen the heart and blood..)

Make this key completely dry from all moisture, and put it once more into a well-sealed fixing-vessel original: Figir-Gefäß; a vessel used for 'fixation,' the process of making a volatile substance stable under heat.. Give it first a fire original symbol: ∆, Ignis so that it all melts original symbol: 日; to flow or liquefy together very gently. And when it has melted together, take it out and grind it upon a
