Skullcap (Scutellaria lateriflora) has a long history of use in North American and traditional herbal medicine as a calming nervine, often employed to address symptoms related to nervous tension, anxiety, and stress. Its traditional use primarily centers on its reputed ability to soothe the nervous system, which indirectly relates to the sympathetic nervous system by promoting relaxation and reducing excitability. Herbal practitioners have historically recommended skullcap for conditions thought to involve an overactive or strained nervous system, such as insomnia, restlessness, and even mild cases of anxiety.

However, while traditional use is well-documented, scientific evidence specifically supporting skullcap's effects on the sympathetic nervous system is limited. Some preclinical studies suggest that certain flavonoids and other constituents in skullcap may possess anxiolytic or sedative properties, but these studies are generally preliminary, conducted in animals, or focus on general CNS (central nervous system) activity rather than direct modulation of the sympathetic branch. Clinical trials in humans remain sparse, and there is no robust scientific consensus confirming skullcap’s efficacy for directly supporting or modulating sympathetic nervous system function.

Overall, the use of skullcap for supporting the sympathetic nervous system is primarily justified by traditional practices and anecdotal reports rather than strong scientific validation.
