Yin Yang Zi & Mu Yao Zi Herbal Blend (Entada phaseoloides) — Dried Food Herb Trio for Wine Soaking & Soup

Yin Yang Zi (阴阳子), also known as Mu Yao Zi (木腰子) and Guo Jiang Long Zi (过江龙子), is the dried seed and vine pod of Entada phaseoloides, a revered traditional herb in Traditional Chinese Medicine (TCM) known as the 'Kidney Tree Treasure' (肾树宝). For generations, this botanical trio — Yin Yang Zi, Shuang Shen Zi, and Feng Liu Guo — has been prized in folk herbal practice as a warming, yang-supporting ingredient used in medicinal wine infusions, decoctions, and nourishing soups. Its nature is warm and its flavor is sweet and slightly astringent, making it a traditional choice for supporting the Kidney channel, warming the lower body, and promoting smooth qi and blood circulation.

Traditional Uses

In folk herbal practice, Yin Yang Zi and its companion herbs are decocted into soups, steeped in wine, and added to longevity formulas to support Kidney yang, warm the lower body, and promote smooth movement of qi and blood. The blend is traditionally soaked in rice wine or grain liquor for several weeks to create a warming tonic, or simmered with pork bone, black chicken, or goji berry in nourishing soups. As a daily tea, it is brewed alone or paired with jujube and ginger for a gentle, warming infusion.
