This disease is a syndrome of deficiency in the root and excess in the superficial, or a mixture of deficiency and excess, with kidney yin deficiency as the root and damp-heat and blood stasis as the superficial, the two being mutually causal. Kidney yin deficiency leads to the internal generation of virtual fire, burning body fluid and causing dryness. In addition, due to the internal heat of yin deficiency, the body fluid is refined into phlegm, which accumulates in the three energizers, obstructing the qi flow, generating internal damp heat. The damp heat is long-term trapped in the kidney meridians, causing qi stagnation and blood stasis, forming a state of "dampness, heat, and blood stasis" obstruction, ultimately presenting a syndrome of deficiency in the root and excess in the superficial, or a mixture of deficiency and excess. Therefore, the present invention combines these drugs to produce a synergistic effect on the efficacy of each drug, thereby achieving the effects of nourishing yin and tonifying the kidney, clearing away heat and dampness, and promoting blood circulation and removing blood stasis.
