Commentary:
The Lungs have a descending action on Qi,
directing it down to the Kidneys. The Kidneys respond by receiving the Qi and holding
it. If this function of the Kidneys is impaired, the Qi rebels and moves upward where
it accumulates in the Lungs. This can cause dyspnea, cough or asthma, which are based
on Kidney deficiency.
