Xiao Chai Hu is mainly used for treating colds and flu, not for treating constipation. The main ingredients of Xiao Chai Hu are Chai Hu, Radix et Rhizoma, Radix Codonopsis, Ginger, Licorice, Jujube, etc. It is mainly used to treat symptoms such as loss of appetite, bloating and fullness in the chest and abdomen, bitterness and dryness in the mouth, etc. Some patients may become constipated after taking Xiao Chai Hu, so Xiao Chai Hu should not be used to treat constipation. If the patient has constipation, it is recommended to adjust the dose of the drug or stop using Xiao Chai Hu in time, as long as the symptoms of external sensation are obviously improved, and to drink more water appropriately, which can be combined with exercise, and also to add a laxative drug. You should also pay attention to the diet not to be too fine, to increase the peristaltic function of the gastrointestinal tract, and to develop good bowel habits.
