"Hmm." Li Xu nodded. "The *Inner Canon of the Yellow Emperor* states: 'The root is in the kidneys, the tip is in the lungs.' Therefore, in treatment, targeting the lungs can also benefit the kidneys. This is called the 'lifting the pot to remove the lid' method. Once the lung qi is unblocked, the water passages will naturally clear, making it easier for the stone to pass."
"You're thinking the same thing I am."
Zhang Liang smiled. The feeling of finding a kindred spirit put him in a great mood.
He picked up his pen and, with a few quick strokes, wrote out a prescription.
After finishing, he pointedly handed it to Li Xu. "What do you think of this formula? Help me look it over."
Li Xu took it and glanced over it.
Glehnia root, Ophiopogon, Rehmannia root, Dendrobium, white peony, Turmeric, Lysimachia, Sea Gold Sand...
"It's good." Li Xu wasn't shy about offering his opinion, despite the other man's seniority.
