Can touching leaves of deadly nightshade be dangerous?

Yes, touching the leaves of deadly nightshade (Atropa belladonna) can be dangerous. The plant contains toxic alkaloids, including atropine and scopolamine, which can be absorbed through the skin. While the risk is higher from ingestion, handling the plant without gloves can lead to poisoning symptoms, such as dilated pupils, increased heart rate, and hallucinations. It’s best to avoid contact with this plant altogether.
