When you cannot open mouth due to wind strike and you breathe noisy breath due to phlegm like sawing, apply 3 moxa cones on RN4 and RN6. Another way is to run a string around the neck and measure it. Put the center of the measured string on the xiphoid process and run each side of the string towards the back. Then, mark the points where each side touches. Apply 7 or 3 x 7 moxa cones on the two points.
