Description of Plant(s) and Culture

Monkshood is a European erect, clump-forming perennial plant up to 4 feet tall; the tuberous root produces an erect, simple, glabrous or slightly hairy stem with alternate, palmately 5 to 7 lobed leaves that are dark green on top and paler beneath. The hood-like, blue-purple flowers grow in long, irregular racemes from June to August. Not heat tolerant, needs full sun or partial shade.

Other varieties: Monk’s cowl (A. carmichaelii) is native to the Szechuan region of China; it is used as a narcotic and as a topical anesthetic ointment in Chinese and homeopathic medicine, but it is too powerful for the home gardener to use. Wolfsbane (A. lycoctonum) has yellow flowers and is familiar from folktales; old superstition held that it repelled werewolves.

Legends, Myths and Stories

Various species of monkshood grow wild in North America, particularly in mountainous regions. These are similarly poisonous. Used as a poison in hunting and war in Europe and Asia since ancient times, monkshood has acquired an extremely bad image through the ages. Its juice was used by soldiers to poison water supplies in the path of advancing enemies, and by hunters to poison spears, arrowheads, and bait.

In Greek legend, monkshood originated from the foam dripping from the fangs of the three-headed dog Cerberus that Herakles (Hercules) brought up from the underworld. Also Hecate, the Greek goddess of the moon, ghosts, witches, and magic, poisoned her father with monkshood. In the Middle Ages witches were associated with monkshood. Since it numbs the senses and gives a sensation of flying, they are said to have smeared it on their bodies and broomsticks.

The name monkshood comes from its hood-shaped flowers. A. napellus, monkshood, is the source of the drug aconite; it was formerly used to make a deadly poison; Shakespeare’s Romeo killed himself with a cup of it.

Uses

Historically, herbalists employed monkshood in traditional preparations intended for the pain associated with neuralgia, sciatica, arthritis, gout, and rheumatism, as well as for certain chronic skin conditions.

Warning

Monkshood is among the most poisonous of plants. Small doses can cause painful death in a few hours. Do not use without medical supervision under any circumstances.
