Hyoscarpus niger, Hyoscyamus niger


The black henbane is a truly exceptional plant. With a look that is very striking - the glandular hairy leaves, crisscrossed with black veins, white flowers, the dry seed pods - it has a very special look to it, but all parts of the plant are highly
poisonous! Antiquity embraced this poisonous herbaceous plant with the sticky hairy leaves and unpleasant smell for reasons of divine worship. In Medieval times, black henbane won recognition for its part in the concoction of "flying potion" and as an intoxicating additive to beer - until the 17th century, beer was mixed with black henbane to enhance its impact. By means of the German medieval beer purity law, henbane and many other beer ingredients were outlawed and no longer used. Ethnologists speculate that the name of the city Pilsen, home of Pilsner beer, derives from the German word for henbane, "Bilsenkraut".

In folk medicine hyoscyamus niger was used as anticonvulsant especially for curing bronchial asthma, , and the oil gained from the plant has also proved to be an effective narcotic and often administered before operations. Since the active ingredient content can vary greatly between plants and plant parts, the treatment often lead to serious poisoning. Today black henbane is only administered in homeopathic dilution.

Caution: The whole plant is very poisonous and is particularly dangerous for children!

Growing instructions
Scatter seeds broadcast on seed sowing compost and press them into the soil gently, possibly slightly covering them from above with finely sieved soil. Keep warm! Germination is often reluctant. Let the seeds pre-soak for six hours in warm water, or treat them with a cold stimulus (temperatures below -12 °C) for four hours before sowing.
The annual henbane plant dies after fall, but can also be biennial, depending on sowing time. Henbane loves bright places and plenty of nitrogen (fertilization). Can also be kept as a houseplant.
