Henbane (Hyoscyamus niger): Identification, Uses, and Safety
Ever wondered what henbane is and whether it’s safe? Henbane is a flowering plant known for strong effects on the body and mind. People have used it for centuries in folk medicine, but it’s also poisonous if used wrongly. This page gives plain, useful facts: how to spot the plant, why it was used, the risks, and what to do if someone is exposed.
What henbane is and how to ID it
Henbane (scientific name Hyoscyamus niger) is a member of the nightshade family. Look for hairy stems, yellowish to brownish flowers often with purple veins, and sticky leaves. The plant can reach about 30–80 cm tall and produces a seed capsule after flowering. It has a bitter smell. Common names include black henbane and stinking nightshade, so if you see those names, it’s the same plant.
People sometimes confuse henbane with other nightshades. If you’re unsure, don’t taste or touch it and take a clear photo for identification. Gardeners and foragers should be cautious—children and pets can mistake parts of the plant for edible greens.
Traditional uses, active compounds, and why it’s risky
Historically, henbane was used as a sedative, pain reliever, or to ease stomach cramps. Modern science shows the plant contains strong alkaloids such as hyoscyamine, scopolamine, and atropine. These chemicals affect the nervous system by blocking certain nerve signals (anticholinergic effects). That explains both the old uses and the dangers.
Small doses can cause dry mouth, blurred vision, and drowsiness. Larger doses can lead to confusion, fast heartbeat, high body temperature, seizures, or even coma. Because the margin between a “small” and “dangerous” dose is narrow, using henbane without medical supervision is unsafe.
Mixing henbane with other drugs raises danger. Anticholinergic medicines (for allergies, Parkinson’s, or some antidepressants), sedatives, and alcohol can make effects worse. If you’re on prescription meds, don’t experiment with henbane.
If you suspect poisoning, act fast. Call your local emergency number or a poison control center and describe what happened. Remove any plant material from the mouth, do not induce vomiting unless a professional tells you to, and get medical help quickly. Keep children and pets away from the plant and consider removing it from areas where they play.
