Take one stalk of grass. For males, measure the left foot; for females, the right foot. Measure from the heel to the tip of the toes, encircling the foot. Then take a stalk of grass folded in half, measuring from the tip of the coccyx (tailbone) to the center of the waist. Apply moxibustion with seven moxa cones (zhuang) at this location. Take another stalk of grass, measuring from the corners of the mouth to the base of the ears, and continue around the head for one full circumference. Then measure from the tip of the nose to the center of the vertex (Dingchuan/Baihui area). Apply moxibustion with seven moxa cones (zhuang) at this location. The effect will be immediate.
