bubble_chart Preparation and Dosage

First, grind alum, green vitriol, and saltpeter into a fine powder and mix well. Place the mixture into a large copper spoon, add 150 ml of fire wine, and heat until dissolved. Once dry, remove and grind into a fine powder. Separately, grind mercury, cinnabar, and realgar into a fine powder until no visible particles remain, then mix with the previously prepared alum and saltpeter powder. Coat the inner wall of the Yangcheng jar with a 1 cm thick layer of paper pulp mud and let it dry in the shade, ensuring no cracks form. Place the prepared mixture into the jar, seal the jar tightly, and secure the jar's mouth with cotton paper strips dipped in honey to fill any gaps. Externally, seal the jar with a mixture of calcined gypsum powder and vinegar. Then, place the jar directly over charcoal fire to heat. Start with a low flame (flame not rising) for half an hour; then use a medium flame (flame reaching halfway up the jar) for another half hour, while occasionally wiping the jar lid with a wet brush. Finally, use a high flame (flame level with the jar's mouth) for the last half hour. After removing from heat and allowing it to cool, open the jar lid and scrape off the medicinal powder from the lid, grinding it finely for later use. Apply a small amount to the wound, cover with a medicated plaster, or wrap with gauze.
