In Other Types of Magic

Outside of flying ointments, henbane has been connected with the mystical for many centuries. Some have argued that the Greek oracles breathed in the smoke of burning henbane in order to enter into a trance state. Others have said that the Scandinavian goddess Bil was associated with henbane (Bilsenkraut). In medieval Germany, henbane was used in rain magic and was thought to make land sterile (henbane does enjoy growing in "waste" land - land that has been stripped of its forest but is not under cultivation). Albertus Magnus claimed that sorcerers burned henbane in order to see demons in its smoke. On a more mundane note, henbane was also previously used to give beer extra punch - "Pilsen[er]" is a corruption of "Bilsen[kraut]." This herb is also known as Hyoscyamus, Hog's-bean, Jupiter's-bean, Symphonica, Cassilata, Cassilago, Deus Caballinus, Henbell, and Jusquiame.

A Long Association With the Afterlife

Henbane was being used by people as far back as the Neolithic period in Scotland - henbane together with barley residues were found in drinking vessels in funerary context there. It's unknown whether the drink was meant for the dead or for shamans or others to ritually imbibe in order to help the dead. Henbane residues have also been found in Bronze Age urns found in the Alps, and a Zoroastrian tale from Persia describes how a man drank henbane in wine and spent a week in the afterlife (he was lucky enough to return). The ancient Greeks believed that the dead in Hades wore wreaths of henbane - this plant of forgetfulness helped them forget their loved ones, whom they would grieve for otherwise.

Toxicity

Our disconnection from nature and our refusal to take responsibility for knowing the natural world mean that we often have very distorted reaction to things like deadly plants. Some people seem to discredit all warnings about poisonous herbs, and others act as if a poisonous plant is as dangerous as plutonium. Neither is a helpful response. This herb is dangerous to life, but that does not mean it cannot be used in ritual at all, only that it must be used with caution. Don't allow it to rest against your skin. If including it in a charm bag, make sure the fabric is tightly woven so that plant dust cannot get through. Wear gloves when handling this herb and do not touch your eyes or mouth without washing them first. If censing with this herb, burn it in a well ventilated area. Henbane is deadly poison - that means that people have died from eating this baneful herb, so please don't do anything stupid with it. If you suspect henbane poisoning, go to the emergency room.

How to grow henbane: Put seeds in water and store in fridge for two weeks, changing water daily (this leaches out anti-germination chemicals). Then sow to germinate in 9 days at room temperature. You can also cold stratify by folding them into a paper towel that has been wet and wrung out; put that in a baggie, and put in fridge for two weeks. Then sow. Be careful not to overwater, because this plant is prone to damping off (suddenly dying from fungus). Transplant when they get two inches tall to a sunny, sandy, alkaline soil (although we have grown this in acidic soil and it did fine). You can crowd them into clumps, because they get a tap root rather than spreading out horizontally. It can be grown in a pot, but it will stay quite small. In the ground, it gets tall enough to flop over. Water when the soil is dry, but give a bit more water when they are flowering. This baneful herb likes compost side dressing (just put some in a ring at the drip line of the plant) and foliar fertilizer (spray organic fertilizer like fish emulsion on the undersides of the leaves in the early morning). Grows 1-3 feet high. These seeds are annual, although henbane can be an annual or a biennial, depending on the particular seed. If it is in a pot, this plant will wilt in heat. Watch out for aphids with this one.  Check under the leaves periodically for tiny white or green bugs.  Use Safer Insecticidal Soap to get rid of them. Slugs and snails also savor the leaves; check for them under pots during the daytime. An annual or biennial (can take two years to flower) depending on when the parent plant produces seeds, this plant has a thick, fleshy, brittle taproot (in fact, you can harvest a very nice mandrake-like root from henbane) but it can still be grown in pots. It does not like soggy soil. This herb is called "Black Henbane" because its flowers tend to have heavy purple veining, but some flowers will have purple veining, some just a purple throat, and some will be golden yellow; all are black henbane. "White Henbane" in contrast has pale yellow flowers. General growing info
