What are the functions and effects of Renzhongbai?

Urine sediment (Urine Solids) is a naturally precipitated solid substance derived from healthy human urine. It typically has functions and effects such as hemostasis, pain relief, clearing heat and reducing fire, removing blood stasis while promoting new tissue growth, moistening the lungs to relieve cough, and nourishing yin to benefit the kidneys. Detailed analysis is as follows:

1. Hemostasis and Pain Relief: Urine sediment has excellent hemostatic properties, especially suitable for external bleeding injuries. It can rapidly coagulate blood, reduce wound bleeding, and has certain analgesic effects, relieving pain caused by wounds and aiding wound healing and recovery.

2. Clearing Heat and Reducing Fire: Urine sediment has a cool nature and can effectively eliminate internal heat pathogens. For symptoms such as sore throat and mouth ulcers caused by internal heat, urine sediment can exert effects of clearing heat and reducing fire, alleviating related symptoms and assisting in recovery.

3. Removing Blood Stasis and Promoting New Tissue Growth: Urine sediment can promote blood circulation and help dissipate internal blood stasis. In cases of traumatic injuries or blood stasis blockage, urine sediment can accelerate the absorption and metabolism of blood stasis, promoting repair and regeneration of injured tissues.

4. Moistening the Lungs and Relieving Cough: Urine sediment has nourishing and protective effects on the respiratory system, capable of moistening the lungs to relieve coughing, alleviating symptoms such as cough and phlegm caused by lung heat or dryness, thereby improving respiratory health.

5. Nourishing Yin and Benefiting the Kidneys: Urine sediment can also nourish yin and benefit the kidneys, providing some relief for symptoms such as soreness and weakness in the waist and knees, dizziness, and tinnitus caused by kidney deficiency. Urine sediment nourishes the kidneys, enhances kidney function, and helps restore the body's yin-yang balance.

When using urine sediment, attention should also be paid to medication safety, particularly for pregnant women, individuals with weak constitutions, and those allergic to urine sediment, who should use it cautiously or avoid it altogether to prevent adverse reactions.
