Skullcap has been linked to several instances of clinically apparent liver injury, but usually in combination with other botanicals.</p></div><div id="Skullcap.Background"><h3>Background</h3><p>Skullcap is a flowering perennial plant native to North America (Scutellaria lateriflora) used for centuries by Native Americans to treat menstrual disorders, nervousness, digestive and kidney problems. The name skullcap refers to the flower’s resemblance to helmets worn by European soldiers. Skullcap was used formerly for nervous disorders, including hysteria, nervous tension, epilepsy and chorea. It is now used largely as a sedative and sleeping pill, often in combination with other herbs such as valerian. Skullcap extracts are prepared from the aerial parts of the Scutellaria lateriflora plant and contain large amounts of flavonoids, including scutellarin and baicalin, which are believed to be the active components accounting for its sedative and antispasmodic activity. It is thought that the flavonoid compounds may act as gamma amino butyric acid (GABA) agonists similar to the benzodiazepines. There are more than 200 species of Scutellaria which have different components and activities as well as potential toxicities. Skullcap is available as a powder to prepare in tea, as a liquid solution and in capsules. Scutellaria is listed as a component in many commercially available, over-the-counter herbal mixtures.</p></div><div id="Skullcap.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Skullcap has been implicated in rare instances of clinically apparent liver injury, although in most cases multiple herbal medications were being taken and the role of skullcap in the hepatic damage was unclear. Furthermore, in some instances phytochemical analysis has identified significant adulterants (germander) or mislabeling in cases of suspected skullcap hepatotoxicity. In reported cases, the onset of symptoms and jaundice occurred within 1 to 12 weeks of starting skullcap, and the serum enzyme pattern was typically hepatocellular. Immunoallergic and autoimmune features were usually absent, although low titers of autoantibodies were not infrequent. Recovery was rapid once the herbal was discontinued, but some cases have resulted in acute liver failure. Chinese skullcap is a different species, but may also have adverse effects on the liver. There have been several reports and small case series of acute liver injury with jaundice arising after 1 to 3 months of starting herbals or dietary supplements with Chinese skullcap (Scutellaria baicalensis), the liver injury resembling that associated with North American skullcap (Scutellaria lateriflora).</p><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.likelihood-score/">Likelihood score</a>: B (very likely but rare cause of clinically apparent liver injury).</p></div><div id="Skullcap.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mechanism of skullcap hepatotoxicity is not known.</p></div><div id="Skullcap.Outcome_and_Management"><h3>Outcome and Management</h3><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.hepatotoxicity/">Hepatotoxicity</a> from skullcap is rare, and is usually mild-to-moderate in severity and resolves rapidly once the botanical is stopped.

Acute hepatitis due to combination of skullcap and valerian.(<a class="bk_pop" href="#Skullcap.REF.1">1</a>)</h3><p>A 53 year old woman developed worsening insomnia, anxiety and jaundice 4 weeks after starting an herbal preparation for sleep that contained skullcap (Scutellaria lateriflora) and valerian root (Valeriana officianalis) for sleep. She had no history of liver disease, alcohol abuse or risk factors for viral hepatitis. She took no other medications except for a cup of herbal tea 2 to 3 times weekly which contained chaparral leaf (Larrea tridentate), and rare use of other miscellaneous herbals. On examination, she was jaundiced but had no fever, rash or signs of chronic liver disease. Laboratory testing showed a serum bilirubin of 9.0 mg/dL with marked increases in serum aminotransferase levels (<a class="def" href="/books/n/livertox/glossary/def-item/glossary.alanine-aminotransferase-alt-/">ALT</a> 1208 U/L, <a class="def" href="/books/n/livertox/glossary/def-item/glossary.aspartate-aminotransferase-ast-/">AST</a> 1082 U/L), and modest increase in alkaline phosphatase (298 U/L) and normal prothrombin time and serum albumin (Table). The white count and differential were normal. Tests for hepatitis A, B and C were negative as were autoantibodies. <a class="def" href="/books/n/livertox/glossary/def-item/glossary.immunoglobulin/">Immunoglobulin</a> levels revealed a slight increase in IgG (2240 mg/dL), but normal IgA and IgM. An anti-CMV IgM assay was positive, but urine cultures were negative and serial titers of anti-CMV were stable. Abdominal ultrasound showed no evidence of gallstones or biliary obstruction. A liver biopsy was not done. She was monitored on no therapy and improved steadily. One month later, the jaundice had resolved and 3 months after stopping the herbal, all liver tests were normal.</p><div id="Skullcap.Key_Points"><h4>Key Points</h4><div id="Skullcap.Tc"

Valerian has been reported to cause an acute hepatitis-like syndrome alone or in combination with skullcap, both of which have purported sedative qualities leading to their mixture in herbal preparations claimed to help sleep.</p></div></div></div><div id="Skullcap.PRODUCT_INFORMATION"><h2 id="_Skullcap_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
