AnxietySleepInflammation

Two different herbs sharing a name. American skullcap is a gentle nervine for anxiety; Chinese skullcap (Scutellaria baicalensis) is a powerful anti-inflammatory with cancer-adjunct research.

EvidenceModerate

Moderate for anxiety reduction (American), inflammation / immune support (Chinese), and emerging cancer-adjunct research (Chinese baicalein). Effects: 2–8 weeks.

American skullcap (Scutellaria lateriflora) has a centuries-long Western herbal use for anxiety, nervous tension, and mild insomnia — mostly via GABA modulation. Chinese skullcap (S. baicalensis) is a different plant with different uses, primarily as an anti-inflammatory and immune modulator. Its bioactive baicalein has reasonable cancer-adjunct, hepatitis, and viral infection evidence. Both safe at recommended doses; read the label for which species.
