Aristolochia debilis is a deciduous vine native to China and Japan. It is also known as Ma Dou Ling, Dutchman's Pipe, or Naked Lady. The plant can grow up to 15 feet long and has wiry stems. The leaves are ovate or oblong-ovate, with a cordate base. The flowers are axillary, solitary or paired, and have a distinctive trumpet-shaped morphology. The plant contains aristolochic acid, which has a range of potential health benefits, including stimulating white blood cell activity, speeding the healing of wounds, and having anti-cancer properties. However, aristolochic acid can also be harmful to the kidneys and liver, so it is important to use this plant under the guidance of a qualified healthcare professional.
