| − | '''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 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.

| − | ==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.
