Southern Fang Ji Root
- Chinese
- 广防己
- Pinyin
- Guang Fang Ji
- Latin
- Radix Aristolochiae Fangchi
Known in TCM as Guang Fang Ji (广防己), this bitter and acrid, cold herb enters the Liver, Kidney, and Bladder. Traditionally, it historically dispelled wind-damp and alleviated painful obstruction ... older materia medica placed Guang Fang Ji in the broader Fang Ji family for swollen painful joints and damp-heat bi, most often applied for edema, joint pain, and rheumatism. Modern research has identified Aristolochic among its active constituents.

Traditional Use
Primary Actions
- Historically dispelled wind-damp and alleviated painful obstruction ... older materia medica placed Guang Fang Ji in the broader Fang Ji family for swollen painful joints and damp-heat bi.
- Historically promoted urination and reduced edema ... it was used for lower-body swelling, difficult urination, and damp accumulation.
- The modern clinical meaning of this record is now overwhelmingly toxicological ... Guang Fang Ji is preserved here as a high-risk historical identity, not as a routine current-use recommendation.
Secondary Actions
- Guang Fang Ji must be distinguished from authentic Han Fang Ji derived from Stephania tetrandra or Botryodiscia tetrandra ... the substitution problem is safety-critical, not academic.
- This page should remain on the documented Aristolochia fangchi lane even though modern safe practice centers on avoiding it.
Classic Formulas
- Historical Fang Ji family use in edema and wind-damp formulas ... preserved here as documentary context only.
- Fang Ji Huang Qi Tang lineage ... relevant only as a reminder that older naming practice did not reliably separate safe and unsafe Fang Ji sources.
- Damp-heat painful-obstruction applications mirrored authentic Fang Ji on paper, which is exactly why substitution caused so much harm.
Classical References
- Older herb lists often treated Guang Fang Ji as a Fang Ji source for edema and painful obstruction before aristolochic-acid toxicity was fully recognized.
- Modern pharmacognosy treats the identity distinction from authentic Han Fang Ji as essential because the traditional name overlap caused real nephropathy and urothelial malignancy cases.
Modern Research
Active Compounds
- Aristolochic acid I
- Aristolochic acid II
- Aristolactam-related metabolites
Studied Effects
- Modern indexed literature on Guang Fang Ji is dominated by authentication and toxicology, including work differentiating authentic Stephania tetrandra from nephrotoxic Aristolochia fangchi (PMID 26632529).
- A 2019 review reinforced the recognition of aristolochic acid toxicity, including the now well-established association with nephropathy and urothelial cancer risk (PMID 30548302).
- Dose-related progression of Chinese herb nephropathy after Aristolochia fangchi exposure was documented clinically as early as 2002, making this one of the clearest danger records in the materia medica naming-confusion literature (PMID 11865085).
