Function: Enhance physical fitness and prevent colds.

Usage: Add 1500ml water into the medicine and decoct it. After the water boils for 5 minutes, turn off the fire and cover the pot. When the temperature is appropriate (to prevent the volatilization of the effective components of the medicine from affecting the curative effect), pour the liquid medicine into the basin, and then put the feet of the child into the basin for soaking. You can rub the soles of your children's feet while washing, every time 15 ~ 20min, preferably every Thursday before going to bed.
