Decoction can be used alone instead of tea, or it can be compatible with Prunella vulgaris and Chrysanthemum.
The function of Sophora japonica:
1. Improved capillary
Rutin can improve the function of capillaries, maintain the normal resistance of capillaries, and prevent bleeding, hypertension and diabetes caused by excessive fragility and permeability of capillaries.
2. Treat hematochezia
Therefore, Sophora japonica is often used as a common medicine to treat hematochezia, which is used for hemorrhoid bleeding, hematochezia, bloody dysentery and hematemesis and epistaxis caused by blood heat.
