Deadly nightshade

Atropa bella-donna

Also calledBelladonna (Italian, 'beautiful lady') · Tollkirsche (German, 'mad cherry') · Belladona (Spanish) · Diānqié 颠茄 (Chinese) · Dwale (Old English) · Atropa belladonna (common older spelling)

A shade-loving perennial of chalky woods whose glossy, sweet black berries can kill a child. Its alkaloid atropine is an essential medicine, still used to restart slow hearts and to counter nerve agents.

Atropa bella-donna, commonly known as deadly nightshade or belladonna, is a toxic perennial herbaceous plant in the nightshade family Solanaceae, which also includes tomatoes, potatoes and eggplant. It is native to Europe and Western Asia, including Turkey, its distribution extending from England in the west to western Ukraine and the Iranian province of Gilan in the east. It is also naturalised or introduced in some parts of Canada, North Africa and the United States. Wikipedia

§1

What it can do

  1. iMakes tropane alkaloids (hyoscyamine, atropine, scopolamine) that block acetylcholine at muscarinic receptors
  2. iiDilates the pupils, relaxes gut and airway muscle and speeds the heart
  3. iiiSome rabbits and other animals carry an enzyme, atropinesterase, that lets them eat it safely

In the medicine cabinet

TraditionUse
European folk medicineLeaf plasters for pain and as an antispasmodic; famously misused as a poison and in 'witches' ointments'
Modern medicineAtropine for slow heart rate, organophosphate and nerve-agent poisoning, before anaesthesia and to dilate pupils; scopolamine for motion sickness

Weight of evidence

Strong. An approved drug, or consistent results in well-run clinical trials.

Active compounds

(–)-hyoscyamine, atropine, scopolamine (hyoscine), apoatropine, belladonnine

CautionDeadly poisonous, and rubbing the eyes after handling the plant can dilate the pupils. Atropine is a prescription drug on the WHO Essential Medicines List. Never self-medicate. Treat suspected poisoning as an emergency.

Of sleeping Nightshade.

John Gerard, The Herball, or Generall Historie of Plantes, London, 1597. What England's best-known herbal said of deadly nightshade, in its own spelling.

The vertues
This kinde of Nightshade causeth sleepe, troubleth the minde, bringeth madnes if a fewe of the berries be inwardly taken, but if mo be giuen they also kill and bring present death. Theophrastus in his 6. booke doth likewise write of Mandrake in this maner; Mandrake causeth sleepe, and if also much of it be taken it bringeth death. The greene leaues of deadly Nightshade may with great aduise be vsed in such cases at Pettimorrell: but if you will follow my counsell, deale not with the fame in any case, and banish it from your gardens and the vse of it also, being a plant so furious and deadly: for it bringeth such as haue eaten thereof into a dead sleepe wherein many haue died, as hath beene often seene and prooued by experience both in England and else where. But to giue you an example hereof it shall not be amisse: It came to passe that three boies of Wisbich in the Ile of Ely, did eate of the pleasant and beautifull fruite hereof, two whereof died in lesse then 8. howers after they had eaten of them.
The place
It groweth in vntilled places neere vnto high waies and the sea marshes and such like places. It groweth very plentifully in Hollande in Lincolneshire, and in the Ile of Elie at a place called Walsoken, neere vnto Wisbitch. I founde it growing without the gate of Highgate neere vnto a pound or pinfold on the left hād.
The time
This flourisheth al the sommer and spring, beareth his seede and flower in Iuly and August.
The temperature
It is colde euen in the fourth degree.
The names
It is called of Dioscorides στρύχνος ὑπνωτικος : of Theophrastus στρύχνος μανικὸς : of the Latines Solanum somniferum somniferum or sleeping Nightshade; and Solanum lethale, or deadly Nightshade; and Solanum manicum, raging Nightshade; of some Apollinaris minor vlticana, & Herba Opfago: in English Dwale or sleeping Nightshade: the Venetians and Italians call it Bella dona: the Germaines Dollwurtz: the lowe Dutch Dulle bessen: in French Morelle mortelle: it commeth very neere vnto Theophrastus hi…

Gerard wrote within Galenic humoral medicine, and his opinions, including about the peoples of the Americas and their crops, are those of 1590s London. His “vertues” are history, not advice. Transcription: Source Library (CC BY-SA 4.0). The whole chapter in the Herball Room.

Marginalia

Renaissance Italian women are said to have used belladonna drops to make their pupils large and alluring. Linnaeus named the genus after Atropos, the Fate who cuts the thread of life.

Curiosity

Scottish chronicle tradition, retold by the 16th-century historian George Buchanan, says the Scots drugged an invading Danish army in the 11th century with drink laced with a sleep-inducing nightshade, often identified as belladonna. It is probably legend.
