The pattern of the patient was Kidney deficiency and her pulse was a little fast. After checking with light strokes on some points, I chose left ST37 and gave Yang Ki to the point. I thought the pulse would be slower, but it became faster and pounding. I reset the previous needling by some tonification on her abdomen and tonified right KD7 with Yang Ki. By this needling, the pulse slowed down.
Another patient had Liver deficiency and her pulse was obviously fast. I chose left LI4 and gave Yang Ki to the point. By only this point, her pulse slowed down and all the pulse positions became proper depth. Her abdomen became soft and even as well. Of course, I finished root treatment by this one point. After 10 minutes rest, the pulse was still slow and in good depth.
The difference between 2 cases is the speed of the fast pulse. If the pulse is obviously fast, tonifying Yang meridian point is really effective, but if the pulse may be a little faster than usual, tonfying Yin meridian seems still effective.
