Aristolochia (fang ji warning)
Aristolochia fangchi
In this catalog solely as a quality-system and toxicity warning. Stehania tetrandra (han fang ji) is a different species; mixing them has killed kidneys.
Safety first
Aristolochic acids are nephrotoxins and urothelial carcinogens (IARC). The Belgian slimming-formula substitution scandal is the cautionary tale for identity testing. Never use. Toxicity warning entry.
This entry exists so you do not use the plant casually. It is not a treatment suggestion.
Tradition vs trials
Traditional record. Classical fang ji language exists in texts. That is not permission. Modern pharmacopoeias exclude aristolochic-acid herbs from safe use.
Trial literature. The human file is epidemic nephropathy and cancer after substitution, not a benefit trial.
