It was formerly used as a medicinal plant, though it is poisonous , and is now occasionally found established outside of its native range as a relic of cultivation. It is now thought to be the cause of thousands of kidney failures in Romania, Bulgaria, Serbia, Bosnia and Herzegovina and Croatia where the plant is thought to be unintentionally consumed through contaminated flour. Urinary tract malignacies among those who have consumed the plant are also reported. The link between renal failure and aristolochid acid, which the plant contains, was discovered after a clinic for obesity in Belgium, some of the patients experienced kidney failure.
Because of its toxicity it must be warned to use the plant or parts of it as a natural medicine.
All parts of the plant are considered carcinogenic (kræftfremkaldende) and kidney damaging.
