Known Hazards

It’s one of the most toxic plants found in the UK, all parts of the plant contain tropane alkaloids symptoms of belladonna poisoning include dilated pupils, sensitivity to light, blurred vision, tachycardia, loss of balance, staggering, headache, rash, flushing, severely dry mouth and throat, slurred speech, urinary retention, constipation, confusion, hallucinations, delirium, convulsions and death.

Could be Confused with…

They have been confused with Bilberries in the past, although the berries can look quite similar the two plants look completely different. Bilberries have a ‘bloom’ on their flesh and are smaller, they grow on a short bush or shrub which has tiny pink flowers. The Nightshade plant looks like an overgrown potato plant, the berries are shiny and the larger flowers are much darker in colour.

Notes on Herbal Uses

It has been used in herbal medicine for centuries as a pain reliever, muscle relaxer, and anti-inflammatory, and to treat menstrual problems, peptic ulcer disease, histaminic reaction, and motion sickness and it possibly useful in treating IBS (irritable bowel syndrome) but I wouldn’t recommend uses it as a home remedy.

Products containing Belladonna are sold in the USA as dietary supplements, cold remedies and even teething powders for toddlers but the FDA (Federal Drug Administration) does not approve it for any medical uses.

Extra notes from the Foragers

The name Belladonna which means ‘beautiful lady’ in Italian refers to its use as a beauty product. Ladies would drop a preparation of the plant into their eyes to cause their pupils to dilate which was considered attractive but prolonged use can cause blindness.

In the past it was thought that witches used Deadly nightshade in flying ointments, it would be mixed with other plants such as opium poppy, hemlock and monkhood and would enable them to fly. In reality they were probably ‘tripping’ so much they thought they were flying!
