  • Differentiation & Application

A toxic plant in the Solanaceae (Nightshade) family, Hyoscyamus niger contains powerful alkaloids such as hyoscyamine, atropine, and scopolamine. It has a long history of use in witchcraft, pain relief, and as a narcotic. In toxic doses, it produces hallucinations, delirium, and spasms.

Historically used as a sedative, analgesic, and antispasmodic in herbal medicine. Employed in medieval “witches’ brews” and as a surgical anaesthetic before safer agents existed.

Proved by Samuel Hahnemann and published in Materia Medica Pura. Additional confirmations by Allen, Hering, and Kent.

Hyoscyamus is the image of disinhibition, mania, and vulnerability of the mind under toxic or emotional pressure. It is a remedy for those who lose social control—who strip, babble, curse, and fear betrayal or poisoning. Behind its violent or sexual behaviour is a deep fear of abandonment, grief, and nervous exhaustion. In children, it is seen in night terrors, twitching, and jealousy of siblings. In adults, in states of toxic delirium, sexual mania, or acute psychosis.

  • For manic or psychotic states with lasciviousness and suspicion
  • Useful in convulsions, especially post-scarlet fever or with suppressed eruptions
