Recently, lion&#x02019;s mane has been purported to improve cognition and relieve anxiety and depression. Lion&#x02019;s mane is generally recognized as safe and has not been linked to serum enzyme elevations during therapy nor to episodes of clinically apparent liver injury.</p></div><div id="LionsMane.Background"><h3>Background</h3><p>Lion&#x02019;s mane (Hericium erinaceus) is saprophytic mushroom found throughout the Northern hemisphere and used for centuries in traditional Chinese medicine generally as a tonic to relief stress, anxiety and depression. Lion&#x02019;s mane mushroom typically grows on the trunks of dead hardwood trees and has distinctive long, white dangling spines that resemble as lion&#x02019;s mane. As a traditional medicine, lion&#x02019;s mane was purported to have multiple potentially beneficial activities including antioxidant, antidiabetic, antilipidemic, antihypertensive, antineoplastic, an immunomodulatory activities as well as hepatoprotective, neuroprotective and cardiovascular protective properties. Most of these effects have been demonstrated in cell culture or in animal models but have not been found in humans. Chemical analyses demonstrate multiple constituents in Hericium erinaceus including unique hericenones, erinacine terpenoids, beta-polysaccharides, and phenolic acids as well as lectins, proteins, fatty acids, sterols, and multiple minerals and vitamins as are found in multiple mushroom species. Which ingredient is responsible for the purported effects of lion&#x02019;s mane are unknown. Erinacines have been found to cross the blood-brain barrier in rats and to stimulate synthesis of nerve growth factor, to speed recovery from ischemic injury, and improve alertness and learning in mice. These neuroprotective and mental cognitive enhancing activities have not been shown to any great extent in humans. At present, lion&#x02019;s mane is not approved for treatment of symptoms or any diseases in humans in the United States. Nevertheless, it is widely available in nutrition centers and on the internet and purported to improve memory and cognitive function. The typical dose in 1 to 3 mg daily. The few studies of short term therapy with lion&#x02019;s mane in humans reported few adverse events and scant evidence of any toxicity. In clinical trials of prolonged therapy, mild gastrointestinal complains of abdominal discomfort, nausea, or diarrhea have been reported usually in less than 10% of treated subjects and generally not requiring discontinuation of the herbal product. At least one example of an acute hypersensitivity reaction to oral lion&#x02019;s mane has been described.</p></div><div id="LionsMane.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Lion&#x02019;s mane has not been subjected to prospective trials of its safety but is widely described as being well tolerated and without side effects. In small clinical trials, there have been no case reports of clinically apparent liver injury attributed to lion&#x02019;s mane, and it is not mentioned or listed in large case series or systematic reviews of the literature on herbal and dietary supplement induced liver injury. Thus, there is little evidence that lion&#x02019;s mane in typical oral doses or as a component of herbal products or teas causes clinically apparent liver injury in humans.</p><p>Likelihood score: E (unlikely cause of clinically apparent liver injury).</p></div><div id="LionsMane.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>Lion&#x02019;s mane has not been linked to serum enzyme elevations during therapy or clinically apparent liver injury. The mechanism by which lion&#x02019;s mane might cause liver injury is not known but more than a thousand components have been identified in Hericium erinaceus extracts, some of which are unique to this species of mushroom. The major components responsible for its purported effects include &#x003b2; glucan polysaccharides, hericenones, and erinacine terpenoids.</p><p>Drug Class: <a href="/books/n/livertox/HerbalDietarySuppl/">Herbal and Dietary Supplements</a></p><p>Other names: Hericium erinaceus, hedgehog fungus, monkey head, bearded tooth, satyr&#x02019;s beard, Yamabushitake, and pom pom.</p></div></div><div id="LionsMane.PRODUCT_INFORMATION"><h2 id="_LionsMane_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
