All parts, but especially the seeds are poisonous and contain the substance ricin. Ingestion can cause vomiting. More worrying is when the toxin enters the bloodstream. It can then cause organ failure and eventually death.
Precautions for poisonous plants in the garden
You may wonder why the above plants are sold if they are so poisonous. However, with some precautions, you can leave them in your garden. Teach yourself to wear gardening gloves as much as possible when working in the garden. Do not touch your face and wash your hands thoroughly afterwards. Warn children from an early age that they should not pick the plants and never eat berries or other parts of the plant. And make sure that pets cannot come near such plants.
