This Really Happened
Three adults (aged 62, 67, and 72 years) ate rice with Spanish broom flowers that were picked from a nearby meadow. There was immediate onset of symptoms, which included abdominal pain, vomiting, diarrhea, and tremors. The patients were seen at a hospital, and a poison center was contacted for treatment recommendations. The patients were treated with activated charcoal and oral diazepam. After a 12-hour observation period, all symptoms had resolved, and the patients were discharged (Riccardi et al., 2006).

What is Spanish broom?
Spanish broom (Spartium junceum) is a perennial shrub that is native to the Mediterranean regions of Europe, Spain, Madeira, and the Canary Islands. In North America, it is mostly found on the western coasts of Washington and California, but it has also been used as an ornamental plant in other regions of similar climate. It is a tall shrub that typically grows to 10–15 feet in height with branching, slim stems that have sparse, oval leaves and yellow, pea-like flowers scattered throughout.
Are Spanish broom plants poisonous?
All parts of the plant have been found to contain compounds called cytisine and sparteine. These compounds are known as nicotinic alkaloids and are commonly found in tobacco plants. These alkaloids bind to nicotinic receptors in our bodies, like a lock and key, to produce a variety of effects on the nervous system. Cytisine is considered a selective, partial stimulant at specific nicotinic receptors that are also the target of smoking cessation drugs like varenicline (Chantix®) and has been used in parts of Eastern Europe as a smoking deterrent. Sparteine can have effects on heart rhythm.
Swallowing the seeds or other parts of Spanish broom can produce potentially toxic effects depending on the amount consumed. In case reports, the initial symptoms typically start within an hour after ingestion and can include mouth and throat irritation, salivation, vomiting, abdominal pain, and diarrhea. Other nervous system effects that might occur include dilated pupils, headaches, confusion, drowsiness, and hallucinations. In severe cases, progression to seizures, muscle paralysis, and respiratory failure can lead to death.
