Belladonna (Atropa belladonna) is a poisonous plant that has been used as a medicine since ancient times. It is named “Belladonna” for the “beautiful women” of Renaissance Italy, who took it to enlarge their pupils, which they found more alluring.
But it also goes by a more sinister name — deadly nightshade — that implies a darker history. Indeed, not only are its dark berries sometimes known as murderer’s berries, sorcerer’s berries, and even devil’s berries, they are thought to be the poison that caused Juliet to appear dead in Shakespeare’s “Romeo and Juliet.”
Is It Safe?
Despite its ominous name, it’s highly unlikely that you’ve never used belladonna. It’s an ingredient in a number of medications, and also sold as a supplement. When your eye doctor dilates your eyes, belladonna is in the eye drops.
But how safe is it?
Belladonna, native to Europe and parts of Asia, can grow up to 5 feet. It has purple flowers and dark, inky berries that are slightly sweet.
Belladonna’s so toxic that eating a small quantity of its leaves or berries can be fatal to humans, particularly children, and some animals. Simply touching the leaves can irritate your skin. According to the National Institutes of Health (NIH), it is not safe when taken orally.
Despite its toxicity, belladonna has some medicinal benefit. The chemicals atropine and scopolamine, which are derived from belladonna, have important medicinal properties.
Atropine and scopolamine have almost the same uses, but atropine is more effective at relaxing muscle spasms and regulating heart rate. It’s also used to dilate the pupils during an eye exam. Atropine can also be an antidote for insecticides and chemical warfare agents.
Scopolamine has many sources, including belladonna, and is more effective at reducing body secretions, such as stomach acid. It can also help motion sickness, via skin patch.

- irritable bowel syndrome
- spastic colon
- stomach ulcers
- Parkinson’s disease
- motion sickness
