When I checked his pulse, Lung position was beating strongly so I thought that it was necessary to calm down Lung. As I checked Liver Meridian by light stroke, Liver seemed useful to control Lung so I tonified Liver by tonification of Yang (Eki/Defensive Ki) with Teishin. After the treatment, overall pulse seemed balanced and Lung pulse seemed calmer.
At the second treatment, he said his cough was a little better, but when I checked his pulse, Lung position was beating strongly. I couldn't see much improvement in his pulse, compared to the last time. But Liver seemed useful to calm down Lung, so I tonified Liver again as well as the last time.
At the third treatment, when I checked his pulse, Lung was beating strongly again. I thought that controlling Lung by tonifying Liver was not enough and I checked Lung Meridian by a little heavier stroke (to check Yin). It seemed useful so I tonified Lung by tonification of Yin (Eiki/Nutritive Ki). Lung pulse became calmer.
At the fourth treatment, he said his cough became much less and when I checked his pulse, Lung pulse was calmer so I tonified Lung by tonfication of Yin as well as the last time.
At the fifth treatment, his cough was completely gone and his Lung pulse was calm.
At the first 2 treatments, I tried to control Lung through Liver but it didn't work well. That would be because there was Ja in Lung, and direct treatment to remove Ja in Lung, which was tonifying Yin, was necessary.
