Yi Huang Tang: Traditional Remedy for Damp-Heat Discharge
Yi Huang Tang is a time-tested herbal formula in Traditional Chinese Medicine (TCM) designed to address conditions related to kidney deficiency and damp-heat. This formula is particularly known for its effectiveness in treating excessive yellow vaginal discharge with a sticky texture and unpleasant odor, often accompanied by a red tongue with a yellow, greasy coating.

The formula features a carefully selected combination of herbs that work synergistically to replenish kidney function, clear heat, and expel dampness:
- Fried Chinese Yam (Shan Yao): Supports kidney and spleen health while providing astringent properties to reduce discharge.
- Fried Euryale Seeds (Qian Shi): Complements Shan Yao by enhancing its astringent effects and nourishing the spleen.
- White Ginkgo Seeds (Bai Guo): Works to reduce damp-heat and control excessive discharge.
- Salt-fried Phellodendron Bark (Huang Bai): A bitter, cooling herb that clears heat and eliminates dampness from the lower body.
