Name of plant:
Belladonna

Catch phrase (Carmina Gadelica or traditional invocation if available):
No known invocation from the Carmina Gadelica is associated with Belladonna. Throughout European folklore, however, Belladonna was regarded with great caution and was often associated with witchcraft, enchantment, and the dangerous powers of the nightshade family.

Family:
Solanaceae (Nightshade Family)

Genus and species:
Atropa belladonna

Other names:
Deadly Nightshade, Belladonna, Dwale, Devil's Cherries, Naughty Man's Cherries, Great Morel

Brief introduction:
Belladonna is a highly poisonous perennial herb native to Europe, North Africa, and Western Asia. Despite its toxicity, it has played an important role in medicine due to its content of powerful tropane alkaloids. Modern pharmaceuticals derived from Belladonna constituents remain important in ophthalmology, anesthesiology, gastroenterology, and emergency medicine.

Traditional uses:
Historically used under strict supervision for:

• Pain relief

• Muscle spasms

• Colic

• Asthma

• Motion sickness

• Neuralgia

• Sedation

Traditional use was always accompanied by significant risk due to its narrow margin between therapeutic and toxic doses.

Historical use:
The name "Belladonna" ("beautiful lady") derives from the Renaissance practice of using eye drops made from the plant to dilate pupils for cosmetic effect. Ancient physicians, medieval herbalists, and later European physicians employed carefully measured preparations for pain, spasms, and neurological conditions. By the nineteenth century, Belladonna became a major pharmaceutical source of atropine and related alkaloids.

Parts used and method of use:
Historically:

• Leaves

• Root

• Whole plant

Preparations:

• Standardized pharmaceutical extracts

• Tinctures (historical)

• Ointments (historical)

Modern medicinal use relies almost exclusively on purified, standardized pharmaceutical preparations rather than crude herbal material.

Use in healing (modern herbal practice):
Belladonna is generally not used in modern herbal self-care because of its toxicity.

Modern medical applications of its isolated alkaloids include:

• Pupil dilation during eye examinations

• Treatment of certain poisonings

• Reduction of secretions during surgery

• Antispasmodic medications

• Management of some cardiac conditions

Pharmacology and biochemistry:
Principal constituents:

• Atropine

• Hyoscyamine

• Scopolamine (hyoscine)

• Tropane alkaloids

Actions:

• Anticholinergic

• Antispasmodic

• Mydriatic (pupil-dilating)

• Antisecretory

• Bronchodilatory

These compounds block muscarinic acetylcholine receptors throughout the body.

Common dosage:

Crude herb dosage is not recommended.

Historically:

• Extremely small and carefully measured doses were used.

Modern usage:

• Pharmaceutical atropine, scopolamine, and related medications are dosed according to established medical protocols.

Because therapeutic and toxic doses are close together, self-dosing with crude Belladonna is considered unsafe.

Safety factors (including side effects):

Highly toxic plant.

Potential symptoms of poisoning:

• Dry mouth

• Dilated pupils

• Blurred vision

• Rapid heartbeat

• Urinary retention

• Flushed skin

• Confusion

• Agitation

• Hallucinations

• Seizures

• Coma

• Death

Children are particularly vulnerable due to the attractive berries.

All parts of the plant are poisonous.

First aid / adverse reaction response:

Suspected Belladonna poisoning is a medical emergency.

If ingestion is suspected:

1. Contact emergency services or poison control immediately.

2. Do not induce vomiting unless specifically instructed by medical professionals.

3. Monitor breathing and consciousness.

4. Seek urgent medical evaluation even if symptoms initially appear mild.

Prompt treatment can be lifesaving.

Drug interactions:

Significant interactions may occur with:

• Antihistamines

• Tricyclic antidepressants

• Antipsychotics

• Antispasmodics

• Parkinson's medications

• Some antiarrhythmics

• Other anticholinergic drugs

Combined use can substantially increase toxicity.

Horticultural requirements:

• USDA / Canadian zone: 5–9

• Soil pH: 6.0–7.5

• Light requirements: Partial shade to full sun

• Moisture: Moderate, well-drained soil

• Other notes (growth habit, harvest timing, etc.):
  Herbaceous perennial reaching 1–2 m in height. Produces bell-shaped purple flowers followed by shiny black berries. Prefers rich woodland soils. Despite its ornamental appearance, it should be planted only where children and pets cannot access it.

Sampling of clinical reports / studies:

• Extensive medical literature exists regarding atropine, hyoscyamine, and scopolamine.

• Atropine remains an essential medication in emergency medicine and ophthalmology.

• Scopolamine is widely used for motion sickness prevention.

• Research has extensively documented Belladonna toxicity and poisoning management.

• Modern clinical use focuses on purified pharmaceutical alkaloids rather than whole-plant preparations.

• The plant's importance today lies primarily as a source of pharmaceutical compounds and a subject of toxicological study.

Apothecary Records Note:
Belladonna occupies a unique place in herbal history as a plant that bridged traditional herbalism and modern pharmacology. While historically used medicinally, it is now regarded primarily as a source of important pharmaceutical drugs. Unlike most herbs in an apothecary, Belladonna should be viewed first as a poisonous medicinal plant requiring professional supervision, not as a remedy for casual or home use. Care should be taken not to confuse it with edible berries, as accidental poisonings continue to occur.
