The specific method is as follows: soak your feet in warm water 1 hour every night before going to bed, then light the moxa stick, aim at Yongquan point on both sides (toes bend to the center of your foot, and a deep depression can be seen in the front of your palm, which is where Yongquan point is located) and smoke with moxa stick. Note that the moxa stick should be placed about 2 inches away from the acupoint, so that there will be a warm but not too hot feeling in some areas until the skin becomes rosy. Each time 10 minute, 10- 15 days is a course of treatment.
