Details</a></p></div></div><div class="body-content whole_rhythm" itemprop="text"><div id="Ashwagandha.OVERVIEW"><h2 id="_Ashwagandha_OVERVIEW_">OVERVIEW</h2><div id="Ashwagandha.Introduction"><h3>Introduction</h3><p>Ashwagandha is a popular Ayurvedic herb used as a general tonic, to improve health, increase energy and reduce stress and anxiety. Ashwagandha has not been implicated in causing serum enzyme elevations during therapy but recently has been implicated in cases of clinically apparent liver injury.</p></div><div id="Ashwagandha.Background"><h3>Background</h3><p>Ashwagandha is an Ayurvedic herb that is derived from extracts of the roots of Withania somnifera, a low growing evergreen shrub that is native to India and Southeast Asia. Ashwagandha is a Sanskrit word meaning horse smell. Sometimes called “Indian ginseng”, it is purported to have neuroprotective and antiinflammatory activities and is used to treat stress, anxiety, insomnia, fatigue, pain, skin diseases, diabetes, arthritis, and epilepsy. It is also used as a general tonic to increase energy, reduce fatigue and counteract the effects of aging. Its efficacy in these conditions has not been shown in controlled prospective studies, but it has been used in Ayurvedic medicine for centuries and is currently the most frequently used Ayurvedic medication. Ashwagandha has recently become a popular herbal product in Western countries. Withania somnifera extracts have more than 100 different chemical constituents including alkaloids, steroidal lactones, saponins, withanolides, withaferins and iron. The ingredient responsible for its purported activities and side effects is not known but withanolides are suspected. Extracts of ashwagandha root are often supplied as capsules or tablets in concentrations of 150 to 600 mg, which are taken one to three times daily, the total daily dose varying widely. Side effects are uncommon and have not been clearly defined. Large doses can cause gastrointestinal upset, diarrhea, nausea and vomiting, probably because of direct irritation to the intestinal mucosa.</p></div><div id="Ashwagandha.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Despite widescale use, ashwagandha is considered generally safe and without major adverse effects. In clinical trials, there have been no reports of serum enzyme elevations occurring during therapy and no mention of serious adverse events or hepatotoxicity. Recently, however, cases of clinically apparent liver injury have been reported in patients taking commercial herbal products that are labelled as containing ashwagandha. Typically, the liver injury presented 2 to 12 weeks after starting ashwagandha usually with a cholestatic or mixed pattern of injury, jaundice, and pruritus. Immunoallergic and autoimmune features were not prominent. Occasional cases were hepatocellular initially, but in general the ensuing jaundice was protracted although it ultimately resolved completely. Rare instances of fatal liver injury or need for emergent liver transplantation have been reported particularly in patients with preexisting liver disease and cirrhosis. Because commercial herbal preparations are often mixtures of herbs and nutritional products and can be mislabeled and contain unknown herbs and medications, it is not always clear whether the reported cases were due to ashwagandha and one of its components or to a contaminant. In several reported cases, however, the commercial product being taken was tested and found to have ashwagandha without other contaminants. First reported in 2017, an increasing number of cases have been reported since. Thus, clinically apparent liver injury attributable to ashwagandha occurs although rarely, and its use should be avoided in patients with cirrhosis or advanced chronic liver disease.</p><p>Likelihood score: B (likely cause of clinically apparent liver injury).</p></div><div id="Ashwagandha.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The cause of hepatotoxicity from products containing ashwagandha is unclear. Among the many ingredients the withanolides have been most suspect. The possibility of mislabeling or adulteration with hepatotoxic herbal products is always an issue in commercial multiingredient dietary supplements.</p></div><div id="Ashwagandha.Outcome_and_Management"><h3>Outcome and Management</h3><p>Most cases of ashwagandha associated liver injury have been mild-to-moderate in severity and self-limited in course, but fatal cases due to acute liver failure or acute-on-chronic liver failure have been described. Protracted jaundice in not uncommon, but chronic liver injury and vanishing bile duct syndrome have not been described. In most instances, the liver injury subsides within 1 to 4 months of discontinuing the herbal product. Rechallenge with the same product should be avoided.</p><p>Other names: Indian Ginseng, Winter Cherry, Poison Gooseberry</p><p>Drug Class: <a href="/books/n/livertox/HerbalDietarySuppl/?report=reader">Herbal and Dietary Supplements</a></p></div></div><div id="Ashwagandha.PRODUCT_INFORMATION"><h2 id="_Ashwagandha_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
