Sijunzi Decoction: Take Radix Codonopsis 10g, Rhizoma Atractylodis Macrocephalae 9g, Poria 9g, and Radix Glycyrrhizae Preparata 6g each time, put them in a medicine pot or porcelain bowl (iron is not allowed), soak them in cold water for half an hour, then fry them with strong fire for 20min, and then fry them with slow fire 15min. Because there are few drugs, there is no need to fry for the second time. You can take it when the weather is warm. Add Astragalus Stewed Chicken 10-20g each time, and pay attention to the long stewing time!
