Stem (tallness of 10-30 cm), is glabrous (bushy). Leaves with long petioles are available in type of a thick bunch close to the base and barely at any point similarly spread over the entire length, intense or sub-heartless tip, glabrous. Size of upper leaves is highly lessened. Inflorescence is thick and raceme is straightforward. Sepals are pubescent, violet, once in a while blue or yellowish green with blue veins. Petals (nectaries) are bushy with truncate recurved lips and hood is gibbous dorsally. Filaments are bristly in the upper however winged in the lower part and these wings end in small teeth (Narayana et al., 2001).

Biotechnological Approach
Present day biotechnological methods have been utilized to assess the impacts of various development controllers on aberrant shoot organogenesis and extraordinary auxiliary metabolite creation in A. violaceum. Callus culture and section chromatography are used for this reason. Plant development controllers, for example, 2, 4dichlorophenoxyacetic corrosive (2,4-D) and kinetin improve the recurrence of callus generation for circuitous recovery. 6-Benzyl aminopurine uncovered noteworthy impacts advancing shoot recovery and a critical auxiliary metabolite generation. Cytokines are development factor and they additionally indicate fixation subordinate impacts of optional metabolite generation. Besides, auxin-cytokine communications additionally improve roundabout shoot recovery and the manufacture of optional metabolites (Rawat et al., 2013).

Medicinal uses
Distinctive ethnic gatherings, for example, Darmese, Martolia and Bhotiasand Johares of Himalayan locale use Aconitum pecies for the treatment of asthma, neuraldisorders, hack and incendiary and cardiovascular ailments. Numerous types of Aconitum which are local to Europe subcontinent have been conceivably used to cure neuralgia, antiulcer, gout, stiffness, and cardiovascular disappointments. A. violaceum has wealthy auxiliary metabolites presented with captivating natural exercises because of the nearness of C19 and C20 diterpenoid, alkaloid, flavanol, kaempferol, acylated flavanol glycosides and glycosides of quercetin (Khan et al., 2013). Rough concentrates of underground parts of the plant procure pain relieving and antipyretic properties and are customarily answered to cure renal pain allergy, high fever, stiffness, wounds, bubbles, and edema. Because of clean properties, this plant is very helpful in the treatment of scorpion and snake nibbles. The plant remove can possibly cure stomach related disarranges including aggravation of the digestive organs, infectious diseases, and scatters of irritate bladder also. Tubers of the plant contain aconitine, which is a neurotoxin, so this plant is useful in enhancing cerebrum work and can cure numerous neurological issues. Plant tubers are in addition utilized for the treatment of tonsillitis and sore throat, debility, and gastritis on the grounds that these are calming and hostile to oxidative. Hostile to proliferative movement of this plant has additionally been accounted for considering its alkaloids against human tumor cell lines, colon and ovarian adenocarcinoma. Half teaspoon root extricates two times every day goes about as tonic, used to treat fever and furthermore for the treatment of heart ailments. Root powder is utilized as a part of easing sciatic torment since it has pain relieving properties (Bhattarai et al., 2010).

Toxic effects
Wild utilization of this plant prompts dangerous impacts because of misidentification, corruption, miss-handling, and defilement. Harmful side effects show up quickly inside 20 to 30 min. The fingers and toes happen bothersome or consuming sensation took after by chills and sweats. Vast amount utilization causes paresthesia (feeling of dryness and harshness in the mouth), absence of the sensation and feeling of extreme icy, colicky looseness of the bowels, heart musicality unsettling influences, rough heaving, skeletal muscle loss of motion and serious torment. Ventricular arrhythmias and cardiovascular breakdown are the significant reasons for death in aconite harming. In Rasa Vagbhata, eight phases called "Asta-vegas" of aconite harming are accounted for. Changes in skin shading took after by tremor, consuming sensation on whole body, rises from mouth, vikratavastha, hanging of shoulders, senseless lastly passing. By the by, Aconitum lethality can be reduced by utilizing assorted strategies previously utilizing it for pharmacological viewpoints. Novel methods and methodologies ought to be utilized for toxicological and concoction examination to enhance its security and in addition quality (Nyirimigabo et al., 2015).

Conservation and management
A. violaceum is abundantly collected due to its tubers. Lamentably, it has been induced and observed that the slant of unsustainable gathering practice is proceeding. Induction is drawn by watching the decrease in zone of inhabitance and environment quality in light of studies and fortuitous confirmation. This plant species has a significant market request inferable from its business use as a plant medicate that is the reason the level of its abuse is very high. It was all in all concurred by specialists that over 40% of the wild populace in the Indian area had declined over the past 10 years. This species was surveyed as powerless in protection evaluation and administration prioritization workshop at Shimla in 2003. This plant is endemic to Himalayan area of Northern Pakistan to Jammu and Kashmir, Himachal Pradesh in India and stretching out up to Nepal. The prevalence of the wild populace is in Indian Himalaya. The present circumstance of species in India is judged as illustrative of the overall populace of the species. This specific plant species is undermined because of territory misfortune and over misuse. It needs quick thought as far as dealing with its environment and additionally feasible gathering rehearses. Dynamic in situ protection ought to be in these territories, where a portion of the subpopulations are available. Observing and reviewing need directly through the known memorable scope of the taxon to decide the states of every single recorded subpopulation. Serious examinations on populace slant, spread procedures and conceptive science must be done to maintain preservation activity programs. In prior circumstances, this plant was utilized to get ready natural definitions by nearby individuals in minute amounts. Presently, commercialization of plant-based medications lately has supported the request and significant misuse of this plant. The over-the-top gathering and absence of sorted out development prompt the enormous consumption of characteristic germplasm of this restoratively critical plant species. Thus, current biotechnological systems must be received to shield this regular germplasm from annihilation to satisfy the rising interest of the plant material. In vitro spread methods have contributed outstandingly to the advance of pharmaceutical industry over the previous decades in a various of ways including varietal development. The use of in vitro systems for quick mass proliferation assumes a key part in recuperation of jeopardized species, in result beating the danger of extinction (Nadeem et al., 2001). Another procedure of protection is cryo-stockpiling or ordinary stockpiling of imperative plant species under in vitro condition to save germplasm. Another normal system of in vitro capacity is the usage of alginate epitome of explants to create engineered seeds (Mishra et al., 2011;Rihan et al., 2011).

CONCLUSIONS
Aconitum violaceum demonstrates wide dissemination on high fields of Central Himalaya. In customary prescription framework, this plant is utilized for curing numerous sicknesses, for example, hack, cardiovascular infections, neuraldisorders, neuralgia, articular torment, gout, stiffness, and heart disappointment also. For the most part root and tubers of the plant are restoratively used in natural details. Dynamic constituents of this plant incorporate atisine, indaconitin, aconitine, indaconitine, flavonoids, starch, sparteine, tannins, tars, benzoic corrosive and aconitic corrosive. Wild utilization of this plant prompts lethal impacts because of misidentification, corruption, miss-handling, and tainting. Dangerous side effects show up quickly inside 20 to 30 min. Due to over misuse, this plant is confronting danger of eradication. Present day biotechnology systems, for example, cryocapacity and solidifying of whole plant and manufactured seeds can assume imperative part in security, administration, and protection of this plant. As it is endemic to a topographically restricted piece of the Himalayas so living space administration hones is likewise received for the preservation of this valuable plant.
