Overview Information

Henbane is a plant. The leaf is used to make medicine. Don’t confuse henbane, sometimes called “fetid nightshade” or “stinking nightshade,” with bittersweet nightshade (Solanum dulcamara) or deadly nightshade (belladonna).

Henbane leaf is used for spasms of the digestive tract.

Some people apply henbane leaf oil directly to the skin for treating scar tissue.

How does it work?

Henbane contains chemicals, such as hyoscyamine and scopolamine, which might relax the muscles lining the digestive tract. Henbane might also relieve muscle tremors and have a calming effect.

Insufficient Evidence for

  • Spasms of the digestive tract, including the stomach and intestines.
  • Treating scar tissue, when the leaf oil is used on the skin.
  • Other conditions.
More evidence is needed to rate the effectiveness of henbane for these uses.

  • Drying medications (Anticholinergic drugs) interacts with HENBANE

    Henbane contains chemicals that cause a drying effect. It also affects the brain and heart. Drying medications called anticholinergic drugs can also cause these effects. Taking henbane and drying medications together might cause side effects including dry skin, dizziness, low blood pressure, fast heartbeat, and other serious side effects.

    Some of these drying medications include atropine, scopolamine, and some medications used for allergies (antihistamines), and for depression (antidepressants).



The appropriate dose of henbane depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for henbane. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
