Known Hazards

All parts of the plant contain the toxic alkaloid cytisine. Its molecular structure has some similarity to that of nicotine and it has similar pharmacological effects. It is sometimes used as an aid to stopping smoking, and it is also sometimes used recreationally, where it can induce a nicotine-like intoxication. Negative side effects can include nausea, vomiting, convulsions, heart pain, headache and, in larger doses, even death via respiratory failure.
