Scutellaria lateriflora (American Skullcap)
Calming herb that supports relaxation and sleep through GABA modulation — gentler than valerian with less morning grogginess.
American Skullcap (Scutellaria lateriflora) is a mint-family herb traditionally used for anxiety, nervous tension, and sleep. Its flavonoids, particularly baicalin and scutellarein, modulate GABA receptors to promote calm without heavy sedation. Often preferred over valerian for its gentler action and lack of morning grogginess. Not to be confused with Chinese skullcap (S. baicalensis).

350-450mg dried herb OR 1-2ml tincture (1:5), up to 3x daily
Can be taken without food
| Form | Type |
|---|---|
| 💧Fresh plant tincture (most traditional) | Recommended |
| 💊Dried herb capsules | Alternative |
| 🍵Tea | Alternative |
Fresh plant tinctures may be more effective than dried herb. Eclectic physicians favored fresh preparations.
