The saying of″Food stagnation，Water retention and improper living circumstances being root of disease″comes from Su Wen ·Bi Lun，which means that diet is also an important factor in the occurrence of Bi syndrome.If diet is imbalanced，the internal organs become disharmonious，the skin and interstices lose their proper function opening and closing，and the acupoints are not firm enough to protect the Evil Factors，which leads to the three pathogenic energies of Wind，Cold，and Dampness to invade，to flow into the Zang and Fu organs，and to generate disease.In the early onset of rheumatoid arthritis（RA），the etiology and pathogenesis are due to dietary obstruction，stagnation of Qi and accumulation of Dampness，leading to stasis and Bi syndrome.During the active stage，it is caused by prolonged dietary accumulation，damage to the Yang of the Middle Jiao，and the Damp-Heat and blood stasis obstruction.During remission period，it is characterized by deficiency of the Zang and Fu organs，deficiency of the Zheng Qi with excess pathogenic factors，and lingering obstruction causing Bi syndrome. Clinical treatment of Bi syndrome should be based on the retention of pathogenic factors from food and drink to promote digestion，regulate Qi to relieve Dampness，unblocking the meridians，and removing Bi syndrome.Treatment should also combine differentiation according to the strength of pathogens and the condition of the organs to apply methods such as resolving Dampness，promoting blood circulation，tonifying deficiency，and tonifying Yang to achieve the desired therapeutic effect.In the early stage of RA，treatment should focus on promoting digestion，regulating Qi and transforming Dampness，unblocking the meridians，and removing Bi syndrome，by using Dayangwei Decoction combined with Zhizhong Decoction；in the active stage，treatment should focus on resolving stagnation，expelling retained fluids，tonifying the Stomach and tonifying Yang，eliminating Dampness-Heat and blood stasis，by using Shizao Decoction combined with Shengyang Sanhuo Decoction；in the remission stage，treatment should focus on tonifying the Zang and Fu organs，supporting the Zheng Qi to expel pathogens，removing stagnation and Bi syndrome，by using Wubi Shanyao Pill or Anshen Pill.
