Etymological Meanings

Etymological Meanings of Deadly Nightshade

Belladonna’s scientific name stems to 1753, when Linnaeus first formally named the plant with a nod to its toxic nature, as well as its cultural roles. Atropa comes from the Greek myth of the Three Fates, who govern the thread of the human lifespan. Clotho spins the thread, Lachesis measures the length, and Atropos — which means “inexorable” or “inflexible” — severs the thread of life.

“Belladonna” comes from the Italian phrase for “beautiful woman.” During the 16th century, Italian courtesans would use drops of deadly nightshade to dilate their pupils and enhance their beauty.

How Poisonous is Deadly Nightshade? 

How Poisonous is Deadly Nightshade

Deadly nightshade is extremely toxic to humans, dogs, cats, and some livestock. All parts of the plant are poisonous; simply touching the plant can cause skin irritation.

Belladonna contains the tropane alkaloids atropine, hyocyamine and scopolamine. These compounds affect the functioning of the body’s nervous system, causing intoxication, hallucination, delirium, and even death. Roots contain the highest concentration of alkaloids.

Ingesting even small amounts of the plant can be fatal for humans or animals. Even eating honey that contains atropine can cause health problems.

Belladonna berries are especially dangerous, as they are attractive, have a sweet taste, and are easily mistaken for other fruits. Eating just a few berries can sicken or kill a child.

Some even used the belladonna flower as a meditation on the nature of good and evil. While the deadly nightshade is indeed deadly, other plants in the nightshade (Solaraceae) family, such as potatoes, are benign food sources. This sets up an easy metaphor to contemplate good and evil.

The Cultural Significance of Deadly Nightshade

A. belladonna has a long, colorful, and occasionally gruesome history. It’s long been used as a weapon and a poison; Early humans made poison from belladonna and applied it to the tips of their arrows.

Several Roman emperors met their demise thanks to this plant. The wives of Augustus and Claudius used atropine to kill their husbands. Roman armies used belladonna to contaminate their foes’ food stores.

The Romans weren’t the only ones to use belladonna against their enemies. As Shakespeare wrote in Macbeth, the Scottish army used belladonna to knock out the Danish army, then murdered them as they slept.

In medieval Europe, the plant was associated with witchcraft and the devil, hence the name “devil’s cherries.” But during the Renaissance, belladonna became linked to beauty, as Venetian women would drop plant extracts in their eyes to dilate their pupils. Carpathian women would carry a nightshade root on their head to enhance their attractiveness.

Atropine was used as an antidote to poisonous gas in World War II. Atropine often figures in novels and movies about assassins and spy craft.

Named for both the Greek Fates and feminine beauty, A. belladonna is both lovely and dangerous.
