Is Deadly Nightshade Poisonous to Touch?

Yes, all parts of the deadly nightshade plant – including its leaves, stems, and berries – contain toxic compounds, primarily alkaloids like atropine, scopolamine, and hyoscyamine. While ingestion is the primary concern, the plant can also be harmful upon contact:

  • Skin Irritation: For some individuals, merely touching the plant can cause skin irritation. This is a dermatological reaction that might show as redness, itching, or rash. It’s not the same as the systemic toxic effects that can result from ingestion, but it’s still uncomfortable.
  • Allergic Reactions: Beyond direct irritation, some people might experience allergic reactions to the plant. Symptoms can vary, ranging from mild skin rashes to more severe reactions like difficulty breathing, especially if they have a known allergy to the plant.

Tropane alkaloids affect the central nervous system and can cause a range of symptoms, including hallucinations, delirium, seizures, and even death.

Benefits and Uses of Deadly Nightshade

Atropine, which is derived from Deadly Nightshade (Atropa belladonna), is used in modern medicine to treat a variety of conditions. Some of the medical uses of atropine include:

Treating Bradycardia

Atropine is also used to treat bradycardia, which is a condition where the heart beats too slowly. Atropine works by blocking the action of the vagus nerve, which slows down the heart rate.

Reducing Secretions

Atropine can be used to reduce secretions during surgery, such as saliva, mucus, and sweat. This helps prevent complications during surgery, such as the aspiration of secretions into the lungs.


Atropine can be used as an antispasmodic to relax smooth muscle in the gastrointestinal tract, making it useful in treating conditions like irritable bowel syndrome.

Note: While atropine can be a useful medication, it can also have side effects, especially in high doses. These side effects can include dry mouth, blurred vision, constipation, difficulty urinating, confusion, and even hallucinations.

Dilating Pupils

Atropine is used by ophthalmologists to dilate the pupils during eye exams, making it easier to examine the eye’s interior.
