'''Ashwagandha''' (''Withania somnifera''), also known as '''Indian ginseng''', '''Winter cherry''', '''Ajagandha''', '''Kanaje Hindi''' and '''Samm Al Ferakh''', is a plant in ''[[Solanaceae]]'' or [[nightshade]] family.
 
 
 
It grows as a stout [[shrub]] that reaches a height of 170cm. Like the [[tomato]] which belongs to the same family, ashwagandha bears yellow flowers and red fruit, though its fruit is [[berry]]-like in size and shape. Ashwagandha grows prolifically in [[India]], [[Pakistan]], and [[Sri Lanka]].
 
 
 
==Medicinal use==
 
 
 
In [[Ayurveda]] ashwaganda is considered a [[rasayana]] herb, a herb that works on a nonspecific basis to increase health and longevity.  This herb is also considered an [[adaptogen]] which is a nontoxic herb that works on a nonspecific basis to normalize physiological function, working on the [[HPA axis]] and the [[neuroendocrine]] system.  The roots and berries of the plant are used in herbal medicine. In Ayurveda, the fresh roots are sometimes boiled in [[milk]], prior to drying, in order to leach out undesirable constituents. {ref} The berries are used as a substitute for [[rennet]], to coagulate milk in [[cheese]] making.
 
 
 
''Ashwagandha'' in [[Sanskrit]] means "horse's smell", probably originating from the odor of its root which resembles that of sweaty [[horse]].[http://www.ayurvediccure.com/ashwagandha.htm] The species name ''somnifera'' means "sleep-bearing" in [[Latin]], indicating it was considered a [[sedative]], but it has been also used for sexual vitality and as an [[adaptogen]]. Some [[herbalist]]s refer to ashwagandha as Indian ginseng, since it is used in [[ayurvedic medicine]] in a way similar to that [[ginseng]] is used in [[traditional Chinese medicine]].
 
 
 
Seven American and four Japanese firms have filed for grant of patents on formulations containing extracts of the herb [[Ashwagandha]]. Fruits, leaves and seeds of the Indian medicinal plant [[withania somnifera]] have been traditionally used for the Ayurvedic system as aphrodisiacs, diuretics and for treating memory loss. The Japanese patent applications are related to the use of the herb as a skin ointment and for promoting reproductive fertility. The U.S based company Natreon has also obtained a patent for an Ashwagandha extract.
 
 
 
Another US establishment, the New England Deaconess Hospital, has taken a patent on an Ashwagandha formulation claimed to alleviate symptoms associated with [[arthritis]].<ref>[http://www.hvk.org/articles/0501/69.html Ashwagandha next on patent hunters list],''Hindu Vivek Kendra'' archive of the ''Times of India'' [[May 16]], [[2001]]</ref>.
 
 
 
The product called "ashwagandha oil" is a combination of ashwagandha with [[almond oil]] and [[rose water]] designed to be used as a [[facial toner]], therefore should not be consumed.

==History==
 
[[Robin Lane Fox]], in his biography of [[Alexander the Great]], claims ''Withania somnifera'' was used in [[wine]] in ancient times.
 
 
 
According to Anne Van Arsdall, ''Withania somnifera'' was called ''apollinaris'' and also ''glofwyrt'' in ''The Old English Herbarium'', and had a legend that [[Apollo]] found it first and gave it to the healer [[Aesculapius]].
 
 
 
The main constituents of ''ashwagandha'' are alkaloids and steroidal lactones. Among the various alkaloids, withanine is the main constituent. The other alkaloids are somniferine, somnine, somniferinine, withananine, pseudo-withanine, tropine, pseudo-tropine, 3-a-gloyloxytropane, choline, cuscohygrine, isopelletierine, anaferine and anahydrine. Two acyl steryl glucoside viz. Sitoindoside VII and sitoindoside VIII have been isolated from root.
 
The leaves contain steroidal lactones, which are commonly called withanolides. The withanolides have C28 steroidal nucleus with C9  side chain, having six membered lactone ring.
 
 
 
Thakur ''''et al''.( 1987) has described ''Withania somnifera'' in their book on major medicinal plants of India, while Puri (2002) has given various recipes in which ''ashwagndha'' is an important ingredient
 
 
 
Puri (2003) in his book on RASAYANA has given monographic account of this adaptogenic plant.  After botanical study, he has given various uses of this herb in Ayurveda,  important Ayurvedic preparations and therapeutic indications and pharmacological activities.  The author has cited about a hundred references.
 
 
 
==Other species==
 
There are over 20 other species of the ''Withania'' [[genus]] that occur in the dry parts of India, [[North Africa]], [[Middle East]], and the [[Mediterranean]]. These include ''Withania coagulens'' and ''Withania simonii'', the roots of which are sometimes used interchangeably with those of ''Withania somnifera''.
 
 
 
''Withania somnifera'' itself has been extensively domesticated from the wild form. In India, at least five different [[cultivar]]s have been developed for increased root size and adaptation to different climates.
