Xia Sang Ju is a famous formula created to combat an epidemic spreading throughout eastern China in 1814. It is bafflingly simple, containing only Xia Ku Cao (Selfheal Flower), Sang Ye (Mulberry Leaf), and Ju Hua (Chrysanthemum). It is said to detoxify pathogenic heat from the body and nourish the Liver system, which in TCM theory includes the eyes. For this reason it has been used to combat the common cold, bird flu, conjuctivitis, and sore eyes. Add the herbs to pot with 6 cups of water. Boil for one hour until the liquid reduces to 2 cups. Strain out the herbs and drink 1 cup, twice daily. Of course, please read instructions on packaging for specific preparation and dosage recommendations.
