Botanical Overview
Henbane (Hyoscyamus niger) is a flowering plant in the Solanaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The nightshade family (Solanaceae) includes herbs, shrubs, and small trees with alternate leaves and star-shaped or trumpet-shaped flowers. The fruits are typically berries or capsules. Many species produce potent alkaloids including tropanes, solanines, and nicotine, making this family both medicinally valuable and potentially toxic.

General Description
Henbane is native to temperate Europe and Siberia, and naturalised in Great Britain and Ireland.
Family Context
The Solanaceae family is widely distributed worldwide. Notable medicinal members include:
- Black Nightshade — 100 documented uses
- Tobacco — 80 documented uses
- Jimsonweed — 66 documented uses
- Hindu Datura — 65 documented uses
Geographic Distribution
Henbane has been recorded in 10 countries and territories worldwide, including Czech Republic, Germany, Spain, France, United Kingdom, and others.
Traditional Uses
Henbane has been traditionally used for respiratory conditions, urinary tract health, and pain and inflammation, among other applications.
Respiratory conditions.
- Asthma
- Cough
Respiratory conditions are addressed through steam inhalation of the herb’s vapors or internal use as a warm tea. The hot infusion acts as an expectorant, helping to loosen phlegm and clear congestion. Some traditions combine it with honey for coughs.
Urinary tract health.
- Cystitis
Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.
Pain and inflammation.
- Anodyne
- Gout
For pain and inflammation, preparations are applied both topically as compresses and taken internally. A warm poultice draws blood to the area and promotes healing, while internal preparations address systemic inflammation.
Active Compounds
Phytochemical research has identified 30 compounds in this species, including a diverse array of phytochemical classes (see the Complete Chemical Inventory below for the full list).
The identified compounds include the following categories:
- Flavonoid: antioxidant compounds that protect cells from oxidative damage
- Coumarin: aromatic compounds with anticoagulant and anti-inflammatory effects
- Sterol: cholesterol-like compounds with anti-inflammatory properties
