The seeds, stems, flowers and leaves of the foxglove plant are poisonous. They contain digitalis glycosides, which are organic compounds that act on the heart. When someone eats part of this attractive plants or sucks on the flowers, the glycosides affect cardiac function, causing an irregular heartbeat. Symptoms can also include digestive issues, headache, blurred vision and confusion and can eventually lead to death.
