Mechanism of action of Skullcap

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.
