Description

It is a herbaceous scrambling or trailing rhizomatous perennial plant growing to 80 cm long. The leaves are heart-shaped, with a distinct petiole. The flowers are 2–3 cm long, pale yellow, tubular, with a broad lip at the top. The fruit is an oval capsule. All parts of the plant have a very strong unpleasant smell. The plant seeks light by ascending the stems of surrounding plants. [2] [3] [4]

Toxicity

It was formerly used as a medicinal plant, though it is now thought to be the cause of thousands of kidney failure cases in Romania, Bulgaria, Serbia, Bosnia and Herzegovina and Croatia. The initial hypothesis that seeds from the plant were unintentionally consumed through contaminated flour has come to be questioned. [5] [6] Urinary tract malignancies among those who have consumed the plant are also reported. [7] The link between kidney failure and aristolochic acid, which the plant contains, was discovered after a clinic for obesity in Belgium used herbal products based on another plant of the same genus as a diuretic. After a few months, some of the patients experienced kidney failure. [8]
