A basic prescription for the treatment of spleen and stomach weakness is Sijunzi Decoction, which is composed of Codonopsis pilosula, Poria cocos, Atractylodes macrocephala and liquorice. This prescription has the effect of strengthening the spleen, removing dampness and tonifying qi. The spleen is the source of qi and blood biochemistry, so when the spleen and stomach are weak, people will have insufficient qi and blood. At this time, you can replenish qi and blood at the same time, and eat Sijunzi Soup and Siwu Soup together. Siwu Decoction is the basic recipe for blood tonic, but this recipe is a little greasy when eaten together, so it often adds a little Amomum villosum to the composition of drugs to promote qi, so as to prevent the greasy tonic drugs from interfering with the spleen and stomach functions.
