'''''Aconitum''''' ({{pron-en|ˌækəˈnaɪtəm}} ''[[Syllable stress of Botanical Latin|A-co-ní-tum]]''<ref>''Sunset Western Garden Book,'' 1995:606–607</ref>), known as '''aconite''', '''monkshood''', '''wolfsbane''', '''leopard's bane''', '''women's bane''', '''Devil's helmet''' or '''blue rocket''',<ref>[http://www.bbc.co.uk/dna/h2g2/A4113983 BBC - h2g2 - Classic Poisons]</ref> is a [[genus]] of flowering [[plant]] belonging to the buttercup family ([[Ranunculaceae]]). There are over 250 [[species]] of ''Aconitum''.
 +
 +
These herbaceous [[perennial plant]]s are chiefly natives of the mountainous parts of the northern hemisphere, growing in moisture retentive but well draining [[soil]]s on mountain meadows. Their [[green|dark green]] [[Leaf|leaves]] lack stipules. They are palmate or deeply palmately lobed with 5–7 segments. Each segment again is 3-lobed with coarse sharp teeth. The leaves have a spiral or alternate arrangement. The lower leaves have long petioles.
 +
 +
These are handsome plants, the tall, erect [[Plant stem|stem]] being crowned by [[raceme]]s of large and eye-catching [[blue]], [[purple]], [[white]], [[yellow]] or [[pink]] zygomorphic [[flower]]s with numerous [[stamen]]s. They are distinguishable by having one of the five petaloid [[sepal]]s (the posterior one), called the galea, in the form of a cylindrical helmet; hence the English name monkshood. There are 2–10 [[petal]]s, in the form of nectaries. The two upper petals are large. They are placed under the hood of the calyx and are supported on long stalks. They  have a hollow spur at their apex, containing the [[nectar (plant)|nectar]]. The other petals are small and scale like or non forming.  The 3–5 [[carpel]]s are partially fused at the base.
 +
 +
The [[fruit]] is a [[Follicle (fruit)|follicle]], a follicle being a dry, unilocular, many-seeded fruit formed from one carpel, and dehiscing by the ventral suture in order to release seeds.

Propagation is effected easily by division of roots in either late fall or early spring; also by seeds sown as soon as mature, in warm spring, in the North, the seeds may be started in small seed-beds in the spring and then be transplanted when the seedlings are about 2 inches high. In the Central States and southward, a year is gained by sowing the seed in late summer or early fall.

The most common plant in this genus, ''Aconitum napellus'' (the Common Monkshood) was considered to be of therapeutic and toxicological importance. Its roots have occasionally been mistaken for [[horseradish]]. It has a short underground stem, from which dark-colored tapering roots descend. The crown or upper portion of the root gives rise to new plants. When touched to one's lip, the juice of the aconite root produces a feeling of numbness and tingling. This plant is used as a food plant by some [[Lepidoptera]] species including [[Dot Moth]], [[Engrailed|The Engrailed]], [[Mouse Moth]], [[Wormwood Pug]], and [[Yellow-tail]].

The roots of ''Aconitum ferox'' supply the [[India]]n ([[Nepal]]) poison called ''bikh'', ''bish'', or ''nabee''. It contains large quantities of the alkaloid [[pseudaconitine]], which is a deadly [[poison]]. ''Aconitum palmatum'' yields another of the bikh poisons. The root of ''Aconitum luridum'', of the [[Himalaya]], is said to be as virulent as that of ''A. ferox'' or ''A. napellus''.

Many species of ''Aconitum'' are cultivated in gardens, having either blue or yellow flowers. ''Aconitum lycoctonum'' (Alpine wolfsbane), is a yellow-flowered species common in the [[Alps]] of [[Switzerland]]. As garden plants the aconites are very ornamental, hardy [[perennial plant]]s. They thrive well in any ordinary garden soil, and will grow beneath the shade of trees. They are easily propagated by divisions of the root or by seeds; care should be taken not to leave pieces of the root where [[livestock]] might eat them, owing to their poisonous character.

Aconite has been ascribed with supernatural powers relating to [[werewolf|werewolves]] and other [[lycanthropy|lycanthropes]], either to repel them, relating to aconite's use in poisoning wolves and other animals, or in some way induce their lycanthropic condition, as aconite was often an important ingredient in witches' magic ointments. In folklore, Aconite was also said to make a person into a werewolf if it is worn, smelled, or eaten. They are also said to kill werewolves if they wear, smell, or eat aconite.

==Pharmacology of Aconite and Aconitine==
 
−
Aconite has long been used in the traditional medicine of India and China.  In [[Ayurveda]] the herb is used to increase pitta and to enhance penetration in small doses. However more frequently the herb is detoxified according to the [[Samskara (Ayurvedic)|samskaras]] process and studies, cited in the detoxification section below show that it no longer possesses active toxicity.  It is used in [[traditional Chinese medicine]] as a treatment for [[Yang]] deficiency, "coldness", general debilitation. The herb is considered hot and toxic. It is prepared in extremely small prepared doses.  More frequently ginger processed aconite, of lower toxicity, "fu zi" is used.  Aconite is one ingredient of [[Tribhuvankirti]], an Ayurvedic preparation for treating a "cold in the head" and fever.<ref>{{cite journal|url=http://www.jpgmonline.com/article.asp?issn=0022-3859;year=1993;volume=39;issue=4;spage=179;epage=82,182a;aulast=Thatte|author=Thatte UM, Rege NN, Phatak SD, Dahanukar SA|title=The flip side of Ayurveda|journal=Journal of postgraduate medicine|year=1993|volume=39|issue=4|pages=179-82}}</ref>  Aconite was mixed with [[patrinia]] and [[coix]], in a famous treatment for [[appendicitis]] described in a formula from the [[Jingui Yaolue]] (ca. 220 A.D.)<ref>{{cite web|url=http://www.itmonline.org/arts/valerian.htm|title=VALERIAN AND NARDOSTACHYS}}</ref>  Aconite was also described in Greek and Roman medicine by [[Theophrastus]], [[Dioscorides]], and [[Pliny the Elder]], who most likely prescribed the Alpine species [[Aconitum lycoctonum]]. The herb was cultivated widely in Europe, probably reaching England before the tenth century, where it was farmed with some difficulty, but came to be widely valued as an [[anodyne]], [[diuretic]], and [[diaphoretic]].<ref>{{cite web|url=http://botanical.com/botanical/mgmh/a/aconi007.html|title=A Modern Herbal}}</ref>  In the nineteenth century much aconite was imported from China, Japan, Fiji, and Tonga, with a number of species used to manufacture alkaloids of varying potency but generally similar effect, most often used externally and rarely internally. Effects of different preparations were standardized by testing on [[guinea pig]]s.<ref>{{cite journal|url=http://www.henriettesherbal.com/eclectic/journals/ajp1881/09-gleanings.html|title=Gleanings in Materia Medica|author=John M.

In Western medicine preparations of aconite were used until just after the middle of the 20th century, but it is no longer employed as it has been replaced by safer and more effective drugs and treatments.  The 1911 British Pharmaceutical Codex regarded the medical uses and toxicity of aconite root or leaves to be virtually identical to that of purified [[aconitine]].<ref>{{cite web|url=http://www.henriettesherbal.com/eclectic/bpc1911/aconitum-nape.html|title=The British Pharmaceutical Codex|year=1911}}</ref>  Aconite first stimulates and later paralyses the nerves of pain, touch, and temperature if applied to the skin or to a mucous membrane; the initial tingling therefore gives place to a long-continued anaesthetic action.  Great caution was required, as abraded skin could absorb a dangerous dose of the drug, and merely tasting some of the concentrated preparations available could be fatal.  The local anaesthesia of peripheral nerves can be attributed to at least eleven alkaloids with varying potency and stability.<ref>{{cite journal|journal=Fundam Clin Pharmacol|date=2004-04|volume=18|issue=2|pages=157-61|title=The local anesthetic activity of Aconitum alkaloids can be explained by their structural properties: a QSAR analysis|author=Bello-Ramírez AM, Nava-Ocampo AA|pmid=15066129}}</ref>  External uses of aconite included treatment of ordinary facial or [[trigeminal neuralgia]], [[rheumatism]], and dental [[periostitis]].

Internal uses were also pursued, to slow the pulse, as a sedative in pericarditis and heart palpitations, and well diluted as a mild [[diaphoretic]], or to reduce feverishness in treatment of colds, pneumonia, quinsy, laryngitis, croup, and asthma due to exposure.  Taken internally, aconite acts very notably on the circulation, the respiration, and the nervous system.  The pulse is slowed, the number of beats per minute being actually reduced, under considerable doses, to forty, or even thirty, per minute. The blood-pressure synchronously falls, and the heart is arrested in [[diastole]]. Immediately before arrest, the heart may beat much faster than normally, though with extreme irregularity, and in the lower animals the auricles may be observed occasionally to miss a beat, as in poisoning by [[veratrine]] and [[colchicum]]. The action of aconitine on the circulation is due to an initial stimulation of the cardio-inhibitory centre in the [[medulla oblongata]] (at the root of the [[vagus nerve]]s), and later to a directly toxic influence on the nerve-ganglia and muscular fibres of the heart itself. The fall in blood-pressure is not due to any direct influence on the vessels. The respiration becomes slower owing to a paralytic action on the respiratory centre and, in warm-blooded animals, death is due to this action, the respiration being arrested before the action of the heart. Aconite further depresses the activity of all nerve-terminals, the sensory being affected before the motor. In small doses, it therefore tends to relieve pain, if this is present. The activity of the spinal cord is similarly depressed. The pupil is at first contracted, and afterwards dilated. The [[telencephalon|cerebrum]] is totally unaffected by aconite, consciousness and the intelligence remaining normal to the last. The [[antipyretic]] action which considerable doses of aconite display is not specific but is the result of its influence on the circulation and respiration and of its slight diaphoretic action.

===Toxicology===
 
−
In a few minutes after the introduction of a poisonous dose of aconite, marked symptoms supervene. The initial signs of poisoning are referable to the [[alimentary]] canal. There is a sensation of burning, tingling, and numbness in the mouth, and of burning in the abdomen. Death usually supervenes before a numbing effect on the [[intestine]] can be observed. After about an hour, there is severe vomiting. Much motor weakness and cutaneous sensations similar to those above described soon follow. The pulse and respiration steadily fail, death occurring from asphyxia. As in [[strychnine]] poisoning, the patient is conscious and clear-minded to the last. The only post-mortem signs are those of [[asphyxia]]. The treatment is to empty the stomach by tube or by a non-depressant [[emetic]]. The physiological antidotes are [[atropine]] and [[digitalis]] or [[strophanthin]], which should be injected subcutaneously in maximal doses. [[Alcohol]], [[strychnine]], and warmth must also be employed.
 
−
 
 
−
The above description of poisoning is characteristic of an oral administration. It should however be noted that aconitine may be easily absorbed through the skin, and poisoning may occur through this route simply by picking the leaves without the use of gloves; the toxin in the sap is absorbed through the skin. From practical experience, the sap oozing from eleven picked leaves will cause cardiac symptoms for a couple of hours. In this event, there will be no gastrointestinal effects. Tingling will however start at the point of absorption, and extend up the arm to the shoulder, after which the heart will start to be affected. The tingling will be followed by numbness—it is fairly unpleasant. As remarked above, atropine is an antidote. Atropine is a constituent of [[Deadly nightshade|Belladonna]].

Aconitine is a potent neurotoxin that blocks [[tetrodotoxin]]-sensitive sodium channels. Pretreatment with [[barakol]]—10 mg/kg [[intravenous|IV]] the compound is isolated from the leaves of ''Cassia siamea Lam''—reduces the incidence of aconitine-induced ventricular fibrillation and ventricular [[tachycardia]], as well as mortality. 5 μg/kg IV of tetrodotoxin also had the same effect. The protective effects of barakol are probably due to the prevention of intracellular sodium ion accumulation.

Aconite was reported by the ''Sunday Mirror'' to have been used as poison in the murder of Pakistan cricket coach, [[Bob Woolmer]] during the [[2007 Cricket World Cup]]. However there is now evidence that Bob Woolmer was not actually murdered.<ref>[http://content-nz.cricinfo.com/woolmer/content/current/story/288539.html]</ref>
 
−
 
 
−
===Detoxification===
 
−
There are methods of processing aconite to reduce toxicity in both [[Chinese medicine]] and [[Ayurveda]].  In Chinese medicine, the traditional [[pao zhi]] or preparation of aconite is to steam with [[ginger]] in a fairly elaborate procedure.  Due to the variable levels of toxicity in any given sample of the dried herb, there are still issues with using it. Most but not all cases of aconite toxicity in Taiwan were due to the consumption of unprocessed aconite.<ref>[http://oneearthherbs.squarespace.com/safety-regulation/] Tilotson, Alan,''Safety and Regulation''</ref><ref>Chinese Herbal Medicine: Materia Medica, Third Edition  by Dan Bensky, Steven Clavey, Erich Stoger, and Andrew Gamble (Hardcover - Sep 2004)</ref>

According to an article by the Indian scientists Thorat and Dahanukar, "Crude aconite is an extremely lethal substance. However, the science of Ayurveda looks upon aconite as a therapeutic entity. Crude aconite is always processed i.e. it undergoes 'samskaras' before being utilized in the Ayurvedic formulations. This study was undertaken in mice, to ascertain whether 'processed' aconite is less toxic as compared to the crude or unprocessed one. It was seen that crude aconite was significantly toxic to mice (100% mortality at a dose of 2.6 mg/mouse) whereas the fully processed aconite was absolutely non-toxic (no mortality at a dose even 8 times as high as that of crude aconite). Further, all the steps in the processing were essential for complete detoxification"    <ref>Thorat S,Dahanukar S. ''Can We Dispense With Ayurvedic Samskaras?

Aconitum (pronounced /ˌækəˈnaɪtəm/ A-co-ní-tum[1]), known as aconite, monkshood, wolfsbane, leopard's bane, women's bane, Devil's helmet or blue rocket,[2] is a genus of flowering plant belonging to the buttercup family (Ranunculaceae). There are over 250 species of Aconitum.

These herbaceous perennial plants are chiefly natives of the mountainous parts of the northern hemisphere, growing in moisture retentive but well draining soils on mountain meadows. Their dark green leaves lack stipules. They are palmate or deeply palmately lobed with 5–7 segments. Each segment again is 3-lobed with coarse sharp teeth. The leaves have a spiral or alternate arrangement. The lower leaves have long petioles.

These are handsome plants, the tall, erect stem being crowned by racemes of large and eye-catching blue, purple, white, yellow or pink zygomorphic flowers with numerous stamens. They are distinguishable by having one of the five petaloid sepals (the posterior one), called the galea, in the form of a cylindrical helmet; hence the English name monkshood. There are 2–10 petals, in the form of nectaries. The two upper petals are large. They are placed under the hood of the calyx and are supported on long stalks. They have a hollow spur at their apex, containing the nectar. The other petals are small and scale like or non forming. The 3–5 carpels are partially fused at the base.

The fruit is a follicle, a follicle being a dry, unilocular, many-seeded fruit formed from one carpel, and dehiscing by the ventral suture in order to release seeds.

Northern Blue Monkshood (Aconitum noveboracense)

Aconitum. Ranunculaceae. Aconite. Monkshood. Wolfsbane. A group of hardy ornamental, perennial herbs, much used in borders and masses for their showy flowers and effective foliage.

Root tuberous, turnip-shaped, or thick-fibrous: st. tall or long, erect, ascending or trailing: lvs. palmately divided or cleft and cut-lobed: fls. large, irregular, showy; sepals 5, the large upper sepal in shape of a hood or helmet; petals 2-5, small; stamens numerous; carpels 3-5, sessile, many-ovuled, forming follicles when ripened. The number of species varies from 18-80, with different botanists. Native in mountain regions of Eu.. Temp. Asia, and 5 in N. Amer. Reichenbach Monographia Generis Aconiti, Leipsic, 1820, 2 vols., folio; Illustratio Specierum Aconiti, Ixnpsic, 1822-7, folio. Many species are planted in European gardens, but only a few have been much used in Amer.

The aconitums yield important drugs, although none of them is grown for this purpose in this country. The officinal aconite is derived from the roots of A. Napellus from England and continental Europe. The leaves are also used for medicinal purposes. A. japonicum yields Japanese aconite; A. chinense. the Chinese aconite; and A. ferox the "bish" or Nepaul aconite. The poisonous alkaloid aconitin is secured from A. Napellus, and similar alkaloids from A. ferox, A. luridum and A. palmatum, of India, A. Fischeri, A. Lycoctonum, A. septentrionale. Not all these species are described here, as fhey are not horticultural subjects.

These plants present a pleasing contrast to the yellow helianthus and rudbeckias, the white of Phlox paniculata, to Chrysanthemum maximum and Anemone japonica. They are also effective for mixing in on shrub borders. The first season, these herbs do not attain their full perfection. Aconitums should be left undisturbed as long as possible. They will survive the northern winters if kept under a leaf-covering, while for the central part of the country, straw or evergreen boughs are sufficient protection.

The following species do well in any garden land, but respond better if given very rich soil. They thrive in open sun, but flowers last longer in shaded places. Aconites should never be planted in or too near the kitchen-garden or the children's garden, as the roots and some of the flowers have a deadly poison. They are suited to the back of the border, as they are tall.

Propagation is effected easily by division of roots in either late fall or early spring; also by seeds sown as soon as mature, in warm spring, in the North, the seeds may be started in small seed-beds in the spring and then be transplanted when the seedlings are about 2 inches high. In the Central States and southward, a year is gained by sowing the seed in late summer or early fall. CH
