It is not exactly clear how this herb works. It seems that there are many different active compounds within it, and researchers are not sure which of these compounds are responsible for the herb's medicinal properties. Some of these active compounds may work in the brain by enhancing the effects of gamma-aminobutyric acid (GABA), a brain chemical that is naturally calming. GABA can slow down or stop certain nerve signals in the brain. This may be why skullcap has anti-anxiety and sedative effects.
There is not enough scientific evidence to evaluate the effectiveness of this herb for any use.
