Dr Chenghui Yu raises the theories of "dampness-heat accumulation" and "the body cannot be tonified although it is vacuous". Dr Yu deems that dampness-heat accumulating in kidney is the pathology of nephritis, the treatment includes resolving dampness and activating blood circulation, strengthening healthy qi to eliminate pathogens. To eliminating dampness-heat toxicity evil, we apply the herbs to clear heat, relieve toxicity and resolve dampness, such as Bai Hua She She Cao, Teng Li Gen, Ban Zhi Lian, Shu Yang Quan. As to the blood stasis, we use herbs to cool blood and activate blood circulation, such as Cortex Radicis (Mudanpi), Danshen (Radix Salviae Miltiorrhizae), Zi Zhu Cao, Han Lian Cao, Bai Shao. For kidney bleeding, the herbs to stop bleeding should be employed, such as Bai Ji, Qian Cao Tan, San Qi, Pu Huang. The turbid damp will be eliminated by Cang Zhu, Bi Xie, Fei Lian, Herba Agastachis (Huoxiang), Pei Lan, Shui Wu Gong.

Dr Yu believes that although there is deficiency, we can not tonity, instead, we should support the healthy energy, apply moistening tonification and mild tonification, use warm tonification, pure tonification cautiously, the powerful tonification is prohibited, we need to nourish but do not make it greasy, tonify spleen Qi, maintain spleen’s functional activities in normal transformation and transportation, it is the key when we consider the prescription. Dr Yu uses Shen Ling Bai Zhu San with modification, the basic ingredients are: raw Huang Qi, fry Bai Zhu, Tai Zi Shen Fu Ling, to tonify spleen and benefit Qi. On the basis of resolving dampness and activating blood circulation, tonifying spleen and promoting Qi, Dr Yu pays more attention to the prevention and controlling of the focus of infection in the early stages. To aim at the diverse infection focus, such as the pharyngitis, rhinitis, oral ulcer, gastritis, enteritis, hepatitis, urinary tract infection etc., the prescription is decided according to the syndrome differentiation. In addition, we should also be aware of the concomitant pathologies and treat accordingly.
