Hyoscyamus niger
Made from henbane — the witch's herb of the Middle Ages, whose scopolamine rides behind the ear of every seasick traveller today.
The whole picture, in one breath
Think of suspicion made flesh: jealousy, the fixed idea of being poisoned or wronged, muttering and picking at the bedclothes, foolish giggling then exposing the body, fear of being alone yet fearing the visitor — the manic-depressive edge of the solanaceae family. Suspicion, exposure, muttering, jealousy: that is Hyoscyamus.
The substance, in plain words
Henbane is the rank-smelling solanaceous herb of castle ditches, rich in scopolamine and hyoscyamine. Its poisoning gives dry delirium with marked amnesia; its alkaloid scopolamine is a leading modern anti-nausea drug, delivered by skin patch to travellers and surgical patients.
The traditional picture Classical sources
The inner state
- Jealous suspicion. The keynote: suspicion of being poisoned or deceived, jealousy over trifles, refusal of drink for fear of poison.
- Foolish, lascivious mania. Giggling, exposing the person, shameless talk — the 'obscene clown' state of the books.
- Muttering and picking. Mumbles and plucks at the bedclothes; constant busy gestures without purpose.
- Fear alternating with rage. Fear of being alone, then fury at company; oscillation is the Hyoscyamus signature.
The body
- Dry, hot, red. Flushed dry skin, dilated pupils, thirstlessness — the family resemblance to Belladonna and Stramonium.
- Convulsions. Spasms and twitchings, especially of single muscles, in the poisoned state.
- Cough worse lying. The books use it in the night cough that drives the patient to sit up, with spasm of the larynx.
- Excoriating discharges. Burning, excoriating urine; the genital excitement of the proving.
- Worse at night. The mental symptoms climb after dark — fear, muttering, picking.
- Paralysis agitans picture. Trembling and stiffness — the old books glimpsed the Parkinson-like face of henbane chemistry.

Where the classical picture comes from
Henbane was the medieval 'witch's herb' — its poisonings, with their amnesiac delirium and shameless mania, were recorded for centuries before the proving. The remedy became the classical portrait of jealousy and suspicion, its oscillating moods mapping the alkaloid's brain action.
The substance in real medicine Pharmacology
What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.
Hyoscyamus's scopolamine is a genuine modern drug: transdermal scopolamine patches prevent motion sickness, and the alkaloid family serves anaesthesia and ophthalmology. Henbane thus holds a rare double identity — the herb of suspicion in the old library, and the travel patch behind the modern traveller's ear.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Stramonium | Mania, delirium | Stramonium rages at darkness and water; Hyoscyamus suspects, mutters and exposes. |
| Belladonna | Hot, red, sudden states | Belladonna is the throbbing fever-delirium; Hyoscyamus the jealous, muttering, picking one. |
| Lachesis muta | Jealousy, suspicion | Lachesis is hot, talkative and left-sided; Hyoscyamus is dry, muttering and oscillating. |
| Anacardium orientale | Two states, wicked impulses | Anacardium alternates angel and devil with hoops and fixed ideas; Hyoscyamus oscillates fear and shameless giggling. |
