Healt Benefits of Aconitum Napellus

Aconitum Napellus

The napello Monkshood (Aconitum napellus L. scientific name, 1753) is a herbaceous plant of the family Ranunculaceae with the top of the flower resembles a vaguely old helmet. It is one of the most toxic plants of the Italian flora widespread in the mountainous areas of the Alps

 

Etymology

The genus name ("Aconite") derives from the greek akòniton (= poisonous plant). The plant is in fact known for its high toxicity since the days of ancient Homeric. This name probably was given a poisonous plant endemic whose habitat was common among the steep cliffs in some areas of Greece. There are two roots that are attributed to the name: Akon (= stone) in reference to its habitat, Kone (= kill), making reference of course to its toxicity. This name was also used as a negative symbol (curse or vengeance) in the mythology of the Mediterranean peoples.

The genus name seems to derive from the use even if it was at war with peaks poisoned arrows and spears. Pliny tells us that the name derives from "Aconae", a town linked to the descent into hell of Hercules (probably near Eraclea).

The pronunciation of the name should be (in the footsteps of the Latin) / ako'nito /, but is often used to say "the Greek" / a'kɔnito / (compare, for example, D'Annunzio, Undulna (vv. 125-128): "Blue are the shadows of the beach as Sparta aconite flowers. / The shake their rattles / Infinity to my astonished gaze '). The danger of the plant was in mind even if the ancient Pliny mentions it as "arsenic plant." It is said that the island of Ceos, the elderly were deleted useless with this poison. In the Middle Ages aconite was called by various names: monaco hood or helmet or Helm of Jupiter blue, always in reference to the top of the flower. In the '500 was known for his alleged ability against the sting of scorpions

The name of the species (napellus) is derived from the Latin for turnip in reference to the particular shape of the rhizome.

The common name derives from the fact that some Strozzalupo ancient peoples used it to poison wolves and foxes.

The currently accepted scientific binomial (Aconitum napellus) has been proposed by Carl von Linné (1707 - 1778) Swedish biologist and writer, considered the father of modern scientific classification of living organisms in the publication "Species Plantarum" in 1753.

Description

They are herbaceous, perennial which can reach heights from 5 to 20 dm. The organic form is defined as rhizomatous geophytes (G rhiz), which are plants that bring the buds in place underground. During the season, no adverse air bodies and the gems are found in underground organs such as rhizomes, an underground stem from which, every year, branching stems and roots aircraft. The plant is at the top glandulosa.

 

Roots

 

The roots are secondary to the rhizome.

 

Stem

 

·         Part underground: the underground part of the stem is a rhizome tuberous taproot conical type. Initially pale and then eventually buy a brown film and branches in many side rootlets. This part of the stem is connected directly to the flowering stalk through the aboveground part.

 

·         Aboveground part: the part above ground is built, sturdy, green, and little ramosa (normally undivided). It is very high for a plant where the stem can pass the meter and a half, while the size can reach 50 to 60 cm.

 

 

Leaves

 

·         Basal leaves: the lower leaves, dark green (slightly brighter) on the upper side and whitish on the bottom, and with obvious veins, are stalked. The lamina (leaf 2 to 3 games or palmate-palmatosette), usually glabrous, is pentagonal and is divided into 5 (or more - up to 7) segments lanceolate but sometimes they are also very linear. These segments may also be serrated. Final length of the segments: 10 mm. Size of the leaves more: width 8 cm, length 12 cm.

 

·         Cauline leaves: cauline leaves are progressively smaller, sessile, with more deeply incised leaf lobes and narrower. The arrangement of leaves along the stem is an alternative and are often near the inflorescence pubescent.

 

Inflorescence

 

The inflorescence is a spike-like panicle terminal, the base is more dense. At the junction of the branches are the leaves of type bratteale. The flowers are stalked and the stalk of the helmet is longer, while the bracts are smaller stalk. The inflorescence axis shows slightly curved hairs simple, but it can also be hairless. Height of inflorescence: 10 to 30 cm.

 

Flower

 

These flowers are flowers considered archaic, or at least derived from flowers by the archaic structure acyclic. The perianth consists of two whorls: the external elements have a protective function and are called tepals or sepals (the distinction of the two terms in this case is ambiguous, and thus subjective), the internal is the nectar (in this flower is the corolla virtually absent). The flowers are pentamerous (five elements) zigomorfa symmetry (or bilateral). The color of the perianth is dark blue - dark violet. The overall shape of a flower is protected and closed, but suited to attract bees. The flowers are not fragrant like the majority of the rest of the flowers of the species of the family Ranunculaceae. Size of flowers: 20 to 30 mm.

 

Formula flower: This plant is suitable for the following floral formula:

 

x K 5, C 2, A many, G 5 (Superior)

Chalice: the cup has five sepals (or tepals) petaloideo type, very different, the upper one is shaped like a helmet or helmet with a hemispherical geometry underlying prolonged beak-shaped, the surface of the helmet can be pubescent. Of the other two were placed lateral sepals oval, and the two lower are more linear / lanceolate and canals. The sepals are not persistent in fruit production. Helmet size: height 60 to 10 mm, width 15 to 20 mm. Lateral size of the petals: width from 9 to 15 mm, length 10 to 20 mm.

 

Corolla: The Corolla is virtually absent, petals (the inner part of the flower) are 8, two of which turned into nectar cylindrical curved forward, ending with a hook in order to better retain the various insect pollinators, the others are reduced to mere tabs.

 

Androecium: stamens (dark) are available in many spiral, collected at the bottom of the flower. Length of nectars: 90 to 10 mm.

 

Gynoecium: the carpels (sessile and spiral) are 5 (rarely less). The pistils, stamens positioned at the center, containing 10 to 20 eggs.

 

Flowering: From June to August. The family of the Ranunculaceae Aconitum napellus is among the last species to bloom in midsummer.

 

Fruits

 

The fruit is an aggregate of 3 (rarely 5) capsules or follicles glabrous, sessile and polispermi (dry fruit with longitudinal development of the cracks to the spillage of seeds). Each follicle ends with a beak law. Inside the follicle contains tiny seeds of tetrahedral, but dishes of brown polished and rough surface. Follicle size: 5 mm width: length from 15 to 20 mm. Seed size: 4 mm.

 

Reproduction

 

Pollination: pollination is ensured mainly by different insects such as bees and wasps are nectar plants (pollination entomophilous).

 

Reproduction: fertilization takes place both through the pollination of flowers (see above), but also for division of the foot (typically vegetable propagation). In particular, the first generation through the seeds in the spring (it takes up to three years for a plant from seed start to bloom), and thereafter through the division of the tubers during flowering. Often close to the old tuber buds are formed with tubercles arranged to produce new plants the following year. Each year, the main tuber, giving rise to new stem dies.

 

Distribution And Habitat

 

Geoelemento: type chorological (source region) is European.

 

Distribution: not only in Italy (in the Alps is common) is present in the mountainous areas of Central Europe: the Carpathian Mountains, Balkan Mountains, Corsica, Pyrenees, Great Britain, Scandinavia, etc.. Some varieties have been reported in the Urals and the Caucasus.

 

Habitat: in Italy the typical habitat of these plants are the areas with partial shade in pastures and on the banks of streams. Frequent is the presence near the huts because of the fertilization of livestock (this plant can be considered synanthropic). These are plants that grow almost always in large groups and prefer clay soils - acidic. The preferred substrate is limestone that is acidic at neutral pH, high nutritional value of the land must be moist.

 

Altitudinal distribution: these plants on the hills you can find up from 500 up to 2600 m above sea level, and then attend the following plans vegetation: hilly, mountainous and subalpine.

 

Systematics

 

The genus includes 250 species Aconitum (a dozen of them are of spontaneous Italian territories) were distributed mainly in temperate regions. The family of Ranunculaceae instead includes over 2000 species distributed in about 47 genera (2500 species and 58 kinds according to other sources).

 

From a systematic point of view (and practice) the species of this genus are classified by color and shape of the flower. In this case the flower "Aconitum napellus" belongs to the group of plants with velvety cap more or less as wide as high and blue flowers.

 

The taxonomic structure of this more than aconite has been revised and modified in recent decades. Sandro Pignatti in the "Flora of Italy" for example, describes four subspecies (vulgare - neomontanum - corsicum - tauricum). Currently, the most recent texts tend to collect many varieties identified for this plant in a single taxon with the following name: Aconitum napellus L. emend. Skalickı (while assigned to a species, the self subsp. Tauricum).

 

The Aconitum napellus is also head of Group A. napellus whose general description (Aconitum napellus sl) is given in "Description". It is a polymorphic group with a tetraploid set of chromosomes and therefore variable. The variability of this species occurs mainly in leaf shape and size and shape of the helmet (still elements that do not allow the secure identification of the various taxa). Frequently form groups with intermediate characters probably ibridogena origin, but can also occur strictly geo-forms. The most difficult from a systematic point of view you have as the boundaries between species and species (or subspecies and between subspecies) are sometimes very small and no variables.

 

The chromosome number of A. napellus is: 2n = 24, 32.

 

Health Benefits

 

Pharmacy

 

Chemical compounds present in the plant: aconitine, mesaconitina, neopellina, delfinina, ipaconitina, indaconitina, aconitic acid, malic acid and acetic acid. Most of these substances are harmful to humans. Therefore, it must be used under the constant supervision of your doctor or pharmacist.

 

In herbal medicine is used for its significant property antineuralgic, sedative, analgesic. In homeopathy is shown against panic attacks, states of shock, sore throat, earache

 

The parts used are the leaves and root, the latter is the main drug plan with a greater degree dell'aconitina, the active healing.

 

Harvest: the leaves during the summer, the tubers in the fall. But be warned: it is a protected species! Moreover, the young shoots can be confused with the radicchio Mountain (Alpine sow-thistle).

 

Toxicity

 

Accidental ingestion of Aconite causes many serious problems: a sense of anguish, loss of sensitivity, slowed breathing, heart weakness, tingling of the face, feeling the skin of the face retreats, ringing in the ears, visual disturbances, contraction of throat which may cause death by asphyxiation. Are sufficient quantities of less than 6 mg aconitine also to cause the death of a grown man.

 

The action is dell'aconitina locates the core, increasing at first but motility resulting in a sudden and often fatal, paralysis of motor nerves, sensory and secretory. For this reason, this plant was often used, especially by the Gauls and Germans, for military reasons. In fact it is poisoned with the tips of arrows and spears before the fight.

 

Have been reported local irritation (with the principle of intoxication) just taking a bunch of this plant in the hands as they can be absorbed through the skin the active ingredients of the poison aconitine. However, it is noteworthy that the venom of the leaves is lower than that of the tubercles.
