Helmet flower, Hoodwort, Quaker bonnet, Scullcap, Scutellaria.
The major active components of skullcap are the flavonoids scutellarin, scutellarein, baicalein, baicalin (the glucuronide of baicalein), dihydrobaicalin, apigenin, luteolin and other methoxyflavones. The iridoid catalpol, and gamma-amino-benzoic acid (GABA) have also been found and there is a small amount of essential oil present composed of monoterpenes and sesquiterpenes.
Use and indications
Skullcap has been used traditionally as a sedative and to treat nervous disorders. Previous reports about its possible toxicity have been found to be because of contamination with Teucrium species; skullcap itself is now considered to be safe to use.
