Known Hazards

Senecio scandens is a commonly used medicinal herb, especially in China, where it is a component of more than 100 compound herbal medicines. However, the plant is known to contain pyrrolizidine alkaloids. These alkaloids, which are derived from various amino acids including ornithine, have a range of antinutritional activities. In particular, they can have a pronounced hepatic toxicity, though the lungs and other organs may be affected as well; mutagenic and carcinogenic activities have also been reported[, ]. The alkaloids have a cumulative effect upon the body and, unless concentrations in a plant are high, occasional use is generally safe and in the case of medicinal herbs, can be very beneficial. In general it is best to seek advice before medicinal use.
