Skullcap at a Glance
Scutellaria lateriflora, American skullcap, is a perennial in the Lamiaceae family. The flowering aerial parts are used in Western herbal traditions.
Traditional Use
American skullcap has a long reputation as a calming or “nervine” herb for tension, restlessness and sleep support.
Research
Small human studies have explored anxiety and mood effects, but evidence remains limited and is not strong enough to establish skullcap as a treatment for anxiety disorders.
Identification and Adulteration
Historically, commercial skullcap has sometimes been adulterated or confused with germander species in the genus Teucrium, some of which are hepatotoxic. Reliable botanical sourcing is therefore an important safety issue.
Safety
Drowsiness can occur and may add to sedatives, sleep medicines or alcohol. Rare liver-injury reports have involved products labeled skullcap, although adulteration and multi-herb formulations complicate causality. People with liver disease should use extra caution with concentrated products. Pregnancy and breastfeeding safety data are inadequate.
Folklore
Skullcap is associated in modern folk herbalism with calm, protection and release of nervous tension.
Bottom Line
American skullcap is a traditional calming herb with limited research and a notable history of adulteration. Correct species and source quality matter. For educational purposes only.
