RESUMO
This paper explored the relationship between systemic lupus erythematosus （SLE） and yin-yang toxins based on the discussion of yin-yang toxin in Synopsis of the Golden Chamber （《金匮要略》）， and found that the two are similar in symptoms， and there is a potential relationship between adverse prognosis factors； and the idea that early treatment of SLE can improve prognosis is in accordance with the opinion in traditional Chinese medicine claiming that yin-yang toxin should be diagnosed and treated as soon as possible. Therefore， it is proposed to take yin-yang as general and toxin pathogen as key to explain the pathogenesis， use yin-yang toxin theory for guidance， discuss on the treatment of SLE around the pathological elements including “toxin， heat， stasis”， and take into account of the kidney essence. Accordingly， Shengma Biejia Decoction （升麻鳖甲汤） is recommended as the basic formula with modifications in accordance with different syndromes in staged treatment， providing reference for the clinical diagnosis and treatment of SLE.
