Aristolochia is not a member of the Aristolochiaceae family, but a member of the Trichoderma family, and contains not aristolochic acid, but aristolactam AII[2] at very low levels. There are no reports that aristolactam AII causes kidney disease, and there is not enough evidence that this substance can harm the kidneys.

And, there is a cross-sectional study on the consumption habits of fishweed and chronic kidney disease, through the study of *** counting 3561 study subjects (male 1167, female 2384, the average age of 29 years old) to eat fishweed of different frequency and time of consumption and other related factors, the results show that there is no difference between the consumption habits of fishweed and the prevalence of kidney disease (P = 0.988), the study did not find a correlation between the habit of eating fishweed and kidney disease, urinary system, and malignant tumors.
