Processing
Fill half a wine jar with a child’s urine; use a jar with a wide mouth. First, make a four-strand wire mesh to suspend a rice bowl inside the jar, approximately 3 cun above the urine. Then, fashion a lead cap in the shape of a conical hat and place it upside down over the jar’s mouth.seal the perimeter tightly with salt mud, and cover the exterior with several layers of rice paper to ensure no air escapes. Then, build a brick stove, place the jar on top, and distill it over a moderate to strong fire using mulberry wood until one stick of incense has burned. Remove it from the heat and let it cool slightly. Gently lift the lead cap, taking care not to let any mud or ash fall, and you will find one bowl of fragrant, clear child’s urine dew in the suspended bowl inside the jar.
Benefits
When true yin is depleted, fire burns the lungs; blood loss due to deficiency leads to internal heat manifesting as throat sores or laryngeal thrush.
Instructions for Use
Pour the elixir into a separate teacup and have the patient consume it—two zhong in total, taken morning and evening. To collect the children’s urine, select 5–6 children who are free of illness, sores, or boils. Each morning, brew a large teapot of pine-moss tea and have each child drink it. When they urinate, discard the first and last portions; collect only the middle portion and store it in the jar.
