What does hyoscyamus mean?
Hyoscyamus is a genus of flowering plants in the nightshade family, Solanaceae. Its best-known species is Hyoscyamus niger, commonly called black henbane or simply henbane. Several members of the genus produce tropane alkaloids, including hyoscyamine and scopolamine, and these chemicals can be toxic to humans and animals. Historical attempts to use the plants medicinally were accompanied by serious poisoning risks, so they are not safely regarded as herbal remedies. In present-day usage, Hyoscyamus is primarily a formal botanical term, with capitalized italic styling indicating that it names a genus. The word also appears in the names of alkaloids associated with the plants. Although often discussed in relation to pharmacology and toxicology, the genus has also become a familiar symbol of danger because of the severe effects that its constituents can produce.
nounA genus of flowering plants in the nightshade family, Solanaceae, whose best-known member is the black henbane, Hyoscyamus niger. Many species contain tropane alkaloids and are toxic.
- A botanical genus in the nightshade family, Solanaceae, comprising species commonly called henbanes.
- A member of this genus, especially Hyoscyamus niger, the black or common henbane.
"The poisonous alkaloids in Hyoscyamus niger have long been recognized, although the plant has no safe medicinal use."
"Hyoscyamus niger grows across much of Europe and southwestern Asia."
"The chemist isolated hyoscyamine from a species of Hyoscyamus during the nineteenth century."
Scientific genera are normally treated as singular collective names, although the plural genus name Hyoscyamuses is occasionally encountered. In formal botanical writing, referring to members as “Hyoscyamus species” is clearer.
"Hyoscyamus species occur in several parts of Europe and Asia."
Henbane earns its sinister reputation: its tropane alkaloids can be dangerously toxic, and even small amounts may have serious effects.

Where does hyoscyamus come from?
Hyoscyamus is a New Latin botanical name based on Latin hyoscyamus, which was borrowed from the ancient Greek plant name hyoskyamos. The Greek compound is generally explained as deriving from hys or hyos, meaning “pig,” and kyamos, meaning “knuckle” or a rounded protuberance, a reference traditionally associated with the plant's capsule or calyx. The name ultimately became attached to henbane and was later adopted as a Linnaean genus name.
