In general, continuous use of Si Jun Zi Tang for about 1 month can improve the function of the spleen and stomach, depending on each individual’s condition and physical status. Si Jun Zi Tang is made from four herbs, namely Ginseng, Atractylodes Macrocephala, Poria and Glycyrrhiza glabra, and is mainly used to treat symptoms such as deficiency of spleen and stomach qi, yellowish complexion, shortness of breath and weakness. The symptoms of spleen and stomach Qi deficiency can be improved after 3 consecutive courses of Si Jun Zi Tang, and some sensitive patients can have certain effect after 2-3 weeks of taking it. If there is no significant improvement in the function of spleen and stomach after taking Sijunzi Tang for 1 month, it is necessary to discontinue the medication, promptly visit the Chinese medicine department or gastroenterology department of the hospital, and follow the doctor’s advice to switch to other medications for symptomatic treatment. During the treatment period, a light and easily digestible diet should be the mainstay, avoiding overly spicy and greasy foods that may irritate the stomach and intestines and aggravate the condition.
