Did you know that the medical an ornamental plant Aconitum napellus is one of the most deadly plants in existence?

Aconite - Monkshood - Wolfsbane (Aconitum napellus).

Aconite - Monkshood - Wolfsbane - Aconitum napellus

Aconitum napellus (monk's-hood, aconite, wolfsbane) is a species of highly toxic flowering plant in the genus Aconitum of the family Ranunculaceae, that is most closely related to delphiniums. The genus grows in cool, moist mountain regions with the highest concentration of species found in high elevations regions of Asia. About 250 species are known with five native to North America.  Plants native to Asia and North America formerly listed as A. napellus are now regarded as separate species. This species is native to Europe.

Aconitum napellus is a long lived tuber forming herbaceous perennial native and endemic to western and central Europe. It is a plant growing to 1 m (3 ft 3 in) tall, with hairless stems and leaves. The leaves are rounded, 5–10 cm (2.0–3.9 in) diameter, palmately divided into five to seven deeply lobed segments. The flowers appearing from midsummer until fall are dark purple to bluish-purple, narrow oblong helmet-shaped, 1–2 cm (0.39–0.79 in) tall. The covering hood of the flower is a domed modified sepal that shrouds the inner parts of the flower. In nature aconite is pollinated by bumblebees so the volume of the hood is sufficiently large to allow access to the bee. The below-ground tubers are fleshy with the species epitaph translating as “little turnips.”  

The plant is extremely poisonous in both ingestion and skin contact. All parts of the plant are poisonous. The name “wolfsbane” comes from the old European practice of poisoning wolves with meat scraps laced with Aconite roots. The name aconitum comes from the Greek ἀêüíéôïí, which may derive from the Greek akon for dart or javelin, the tips of which were poisoned with the substance, or from akonae, because of the rocky ground on which the plant was thought to grow

Like other species in the genus, A. napellus contains several poisonous compounds, including enough cardiac poison that it was used on spears and arrows for hunting and battle in ancient times. The poisonous principle has been used to coat poisonous arrows, and in Alaska, harpoons for whale hunting. A. napellus has a long history of use as a poison, with cases going back thousands of years. During the ancient Roman period of European history, the plant was often used to eliminate criminals and enemies, and by the end of the period it was banned and anyone growing A. napellus could have been legally sentenced to death. Aconites have been used more recently in murder plots. It has been the favorite poison of suspense writers for the past several centuries and its use continues in the plethora of modern day who-done-its on TV serials. It contain the chemical alkaloids aconitine, mesaconitine, hypaconitine and jesaconitine, which are highly toxic.

Aconite, although it is a very powerful poison, is considered one of the top medicinal plants. Aconite has been used since ancient times, especially as an antidote to poisoning. Since the entire plant is itself very toxic, however, any use should be under the guidance of a skilled practitioner. All parts of the plant are used medicinally. The root is the most important and this is harvested as soon as the plant dies down in the autumn and is dried before use. The other parts of the plant are less important and are used fresh, being harvested when the plant is coming into flower. The root is analgesic, anodyne, antirheumatic, diaphoretic, diuretic, irritant and sedative. Due to its poisonous nature, it is not normally used internally though it has been used in the treatment of fevers. Externally, it is applied to unbroken skin in the treatment of rheumatism, painful bruises, neuralgia etc. All parts of the plant, except the root, are harvested when the plant is in flower and used to make a homeopathic medicine. This is analgesic and sedative and is used especially in the treatment of fevers, inflammation, bronchitis, neuralgia etc.

Aconitum napellus is grown in gardens for its attractive spike-like inflorescences and showy blue flowers. It is a cut flower crop used for fresh cutting material and sometimes used as dried material. The species has a low natural propagation rate under cultivation and is propagated by seed or by removing offsets that are generated each year from the rootstocks. The use of micropropagation protocols has been studied.[8] This species has been crossed with other Aconitums to produce attractive hybrids for garden use, including Aconitum x cammarum.

But having monkshood in your garden amongst all the other theoretically poisonous plants — everything from azaleas to potatoes — is not by itself dangerous. Brushing against the plant or even accidental ingestion of a small amount of leaf tissue is not going to be fatal. As with any poison, the dose administered is what causes the problem. Not planting any potentially poisonous plant with easy to confuse tubers in the vegetable garden is a common-sense precaution. And, obviously, don’t assume anything green is good to add to a salad.
