Child's Urine Classic Formulas — Natural Herb Library

Primary Actions

Nourishes Yin and descends deficiency fire - Tong Bian is an old special medicinal substance used when heat signs arise from yin depletion, especially coughing or bleeding with dryness and internal heat.
Stops bleeding while cooling the blood - classical indications include nosebleed, hemoptysis, hematemesis, and other bleeding presentations attributed to heat or consumptive irritation.
Dispels blood stasis from trauma or postpartum retention - it appears in old records for traumatic pain, congealed blood, and postpartum faintness or pain where stasis and fluid loss coexist.
Functions as a medicated guide or formula vehicle as much as a stand-alone substance - in older prescribing, Tong Bian often directs mineral or blood-moving medicinals downward while tempering excessive heat.

Hua Rui Shi San (花蕊石散) - classical emergency bleeding formula traditionally taken with warmed Tong Bian to guide the calcined minerals inward and downward while transforming stasis.
Xiao Ding Feng Zhu (小定风珠) - older yin-fluid depletion formula in which Tong Bian appears as a minor fluid-nourishing, downward-guiding component.
Sheng Hua Tang historical preparations (生化汤旧法) - some older postpartum methods record Tong Bian as a preparation liquid, though modern practice omits it.

TCM Wiki identifies Tong Bian under the broader Ren Niao / Urina Hominis tradition and gives actions of nourishing yin, lowering fire, stopping bleeding, and dissipating blood stasis.
Me and Qi formula monographs for Hua Rui Shi San, Da Ding Feng Zhu, and Sheng Hua Tang all preserve Tong Bian as a historical vehicle or ingredient while noting that it is generally no longer used in modern practice.
IMPORT NOTE: the XLSX stub labeled this item as 'Child's Dung,' but Tong Bian (童便) refers to child's urine, historically from healthy prepubescent boys.
