- Guang Fang Ji contains aristolochic acid, a known nephrotoxic compound. The traditional method of preparation (boiling in water) is believed to lower the toxicity since aristolochic acid has a low water solubility but extreme care should be taken.
- In Belgium, a weight loss clinic used a large dose of the raw powder along with acetazolamide and several other compounds resulting in at least 53 cases of renal fibrosis.
