Arstochia clematitis

Aristolochia clematitis (birthwort) is a plant that has a long history of use in traditional medicine. However, it’s extremely important to note that it contains aristolochic acid, a substance that is highly toxic and can cause severe kidney damage, cancer, and even death. Because of these serious risks, Aristolochia clematitis and other Aristolochia species should absolutely not be used internally or externally without the strict supervision of a qualified healthcare professional who is fully aware of the risks and appropriate preparation methods (if any are deemed safe). You may find products containing it on some websites, but their safety is highly questionable, and their use is strongly discouraged. Do not use this plant without explicit guidance from a medical doctor.
