It is proposed that the pathogenesis of rheumatoid arthritis （RA） is centered on deficiency， dampness， and blood stasis， which interact with and evolve into one another during the onset and progression of the disease. The development of RA is closely associated with insufficiency of healthy

qi

and the interbinding of dampness and blood stasis. Accordingly， treatment emphasizes an integrated approach that combines tonifying deficiency， eliminating dampness， and resolving blood stasis， and is implemented in three main stages. In the initial stage， therapy focuses on supporting healthy

qi

， dispelling dampness， and relieving impediment， with modified
