The recipe name Sijunzi Decoction (Abbreviation: Sijun Decoction) comes from "Taiping Huimin Heji Bureau Prescription" Classification of tonics - Qi-tonifying components: ginseng (9g), Atractylodes (9g), Poria (9g) Zhigancao (6 grams) functions to replenish qi and strengthen the spleen. Indications: Spleen and stomach qi deficiency syndrome. Pale complexion, low voice, shortness of breath and fatigue, less food and loose stools, pale tongue with white coating, and weak pulse. (This prescription is often used for chronic gastritis, stomach and duodenal ulcers, and other people with spleen deficiency.) In the formula, ginseng is sweet and warm, and it can replenish qi and nourish the middle. Atractylodes can strengthen the spleen and remove dampness, and it can be combined with ginseng to replenish qi and strengthen the spleen. It is a minister; Poria cocos is used as an adjuvant for expelling dampness and strengthening the spleen; Zhigancao is a soothing and licorifying agent. The four flavors are all mild, warm but not dry, tonic but not harsh, hence the name Sijunzi Decoction. Solution: The syndrome of this prescription is caused by deficiency of spleen and stomach qi and weak transportation and transformation. The spleen and stomach are the foundation of acquired qi and the source of qi and blood biochemistry. If the spleen and stomach qi are deficient and the reception and transportation are weak, the diet will be reduced; dampness and turbidity are generated internally, so loose stools will be thin; the spleen governs the muscles, and the spleen and stomach qi will be weak, and the muscles of the limbs will have no ability to receive. Therefore, the limbs are weak; the biochemistry of qi and blood is insufficient, and the face is not flushed with blood, and the face is pale and pale; the spleen is the mother of the lungs, and if the spleen and stomach are weak, the lung qi will be extinguished first, so shortness of breath and low voice will be seen; pale tongue with white coating, A weak pulse is a sign of Qi deficiency. As stated in the Medical Prescription Examination: "If your face is pale, look at it and you will know that your Qi is deficient; if you speak softly, you will hear it and you will know that your Qi is deficient; if your limbs are weak, you will ask about it and you will know that your Qi is deficient; if your pulse is coming, If it is weak, cut it and find out that the Qi is deficient. "The treatment should be to replenish the Qi of the spleen and stomach to restore its function of transporting, transforming and accepting." The ginseng in the prescription is sweet and warm, nourishes qi, strengthens the spleen and nourishes the stomach. I use the bitter and warm Atractylodes macrocephala to invigorate the spleen and remove dampness, strengthen the power of replenishing qi and assisting transportation; I use the sweet and light Poria cocos to strengthen the spleen and exude dampness. When combined with the Atractylodes macrocephala, the effect of strengthening the spleen and removing dampness is enhanced. Use roasted licorice to replenish qi and harmonize the central nervous system, and harmonize various medicines. The compatibility of the four medicines can effectively replenish qi and strengthen the spleen.
