withania somnifera, known commonly as ashwagandha or winter cherry,[2][3][4] is an evergreen shrub in the solanaceae or nightshade family that grows in india, the middle east, and parts of africa. several other species in the genus withania are morphologically similar.[3] the plant, particularly its root powder, has been used for centuries in traditional indian medicine. although used in herbalism and sold as a dietary supplement, there is insufficient scientific evidence that it is safe or effective for treating any health condition or disease.[3][4] description this species is a short shrub growing 35–75 cm (14–30 in) tall. tomentose branches extend radially from a central stem. leaves are dull green, elliptic, usually up to 10–12 cm (3.9–4.7 in) long. the flowers are small, green and bell-shaped. the ripe fruit is orange-red.[3] etymology look up ashwagandha in wiktionary, the free dictionary. the latin species name somnifera means "sleep-inducing".[5] the name "ashwagandha" is a combination of the sanskrit words 'ashva', meaning horse, and 'gandha', meaning smell, reflecting that the root has a strong horse-like odor.[3] cultivation withania somnifera is cultivated in many of the drier regions of india. it is also found in nepal, sri lanka, china,[6] and yemen.[7] it prefers dry stony soil with sun to partial shade. to propagate it can be grown from seed in the early spring, or from greenwood cuttings in the later spring.[8] diseases and pests withania somnifera is prone to several pests and diseases. leaf spot disease caused by alternaria alternata is the most prevalent disease, which occurs in a severe form in punjab, haryana, and himachal pradesh. a decline in the concentration of its secondary metabolites occurs by leaf spot disease.[9] a treehopper feeds on the apical portions of the stem, making them rough and woody in appearance and brown in colour.[citation needed] the carmine red spider mite (tetranychus urticae) is the most prevalent pest of the plant in india.[10] in recent years, this plant has been serving as a new reservoir host for an invasive mealybug species phenacoccus solenopsis.[11] phytochemistry the main phytochemical constituents are withanolides – which are triterpene lactones – withaferin a, alkaloids, steroidal lactones, tropine, and cuscohygrine.[3] some 40 withanolides, 12 alkaloids, and numerous sitoindosides have been isolated.[3] withanolides are structurally similar to the ginsenosides of panax ginseng, leading to a common name for w. somnifera, "indian ginseng".[3] adverse effects w. somnifera may cause adverse effects if taken alone or together with prescription drugs.[3][4][12] side effects may include diarrhea, headache, sedation, or nausea, and the product should not be used during pregnancy or breastfeeding.[4][12]
