1. First, put the traditional Chinese medicine into a medicine bag with excellent water permeability, boil the water to 100 degree, put the medicine bag into a larger pot and soak it in boiling water with 100 degree. The more water, the better. When the temperature is right, take out the medicine bag and put the pot in the toilet so that the patient can fumigate the anus. Be sure to control the temperature to prevent scalding the anus.

2. When the temperature of the liquid medicine is slightly higher than the normal temperature, you can take a sitz bath, take out the basin, and the patient sits in the basin, so that the liquid medicine does not completely bypass the anus. The duration of sitz bath is about 15 minutes, and the sitz bath should be ended in time after the temperature of the liquid medicine is lowered, so as to avoid adverse effects caused by too low temperature.
