Li Xu pointed at Tang Zhanhu and continued, "Look at the patient. The occasional pain in his stomach is a sign of disharmony between the spleen and stomach. His fatigue and the weakness in his lower back and knees are signs of Qi and blood deficiency, and insufficient kidney essence. His pale tongue, thin coating, and fine, weak pulse all further confirm the diagnosis of dual deficiency in the spleen and kidneys, along with insufficient Qi and blood."
"Therefore, our treatment principle must be to nourish the spleen and kidneys while also regulating Qi to stop the pain."
