Lesser skullcap

Scutellarein and its glucuronide scutellarin are the hallmark 4'-hydroxyflavones that accumulate in the aerial parts (leaves and stems) of Scutellaria species. They are reported to have antioxidant, anti-inflammatory and vasoprotective activity in genus-level studies, but species-specific data for S. minor are essentially absent.

Baicalein and the glycoside baicalin are the dominant 4'-deoxyflavones of the genus, concentrated mainly in roots. They are the best-studied Scutellaria flavones (antioxidant, anti-inflammatory, GABAergic), though their presence and levels in S. minor have not been directly measured.

Apigenin is a widely distributed dietary flavone reported among the aerial-part flavones of Scutellaria. It has anxiolytic and anti-inflammatory activity in general pharmacological literature.

Chrysin was found to accumulate in the leaves of every Scutellaria species examined in genus metabolite surveys, suggesting it is a probable component of S. minor foliage as well. It shows antioxidant and anxiolytic activity in the literature.

In the Western herbal tradition skullcaps are used as gentle nervines. A tea is made by steeping roughly 1–2 g of the dried flowering aerial parts in a cup of freshly boiled water for 10–15 minutes, covered. Note that essentially all traditional and clinical skullcap use rests on Scutellaria lateriflora and S. galericulata; S. minor itself has scant documented medicinal use and no established dosing.

Alcoholic tinctures of the fresh or dried flowering herb are the usual commercial form for skullcap. Because identity confusion within the genus is common, material should be botanically authenticated; adulteration of "skullcap" products with hepatotoxic Teucrium (germander) has historically been a safety concern for the trade.
