Du Heng's therapeutic approach was completely different from Sun Jiaxiang's.
Sun Jiaxiang's starting point was the slogan traditional Chinese medicine always emphasized: cure the root cause of the disease.
The root cause of Su Nan's condition was his cardiopulmonary system, so Sun Jiaxiang planned to start there by lowering blood pressure and boosting the cardiopulmonary original qi. As long as cardiopulmonary function was restored, then Su Nan's problems could be easily solved.
As for the current kidney function failure, that was caused by pulmonary dysfunction.
The heart governs blood, and the lungs govern qi. As long as the qi and blood were robust and fluent, would kidney yang deficiency still be a problem?
Therefore, Sun Jiaxiang had followed this path to treat Su Nan, hoping to bring about a change.
But things did not go as he wished. After two doses of medicine, there was no improvement at all.
