30g of Rhizoma Coptidis, water 1000ml, put a piece of Rhizoma Coptidis, boil it and simmer it for 20min, filter off the residue, wash it with clean gauze after the soup is cool, and wet compress it three times a day. However, it can only be used as an auxiliary treatment for viral conjunctivitis, and antiviral treatment must be actively carried out, preferably interferon treatment! Eyes are very important and delicate, I hope to attract attention!
