Guelder rose (Viburnum opulus) has a long history of traditional use in herbal medicine, particularly for its supposed calming and antispasmodic effects, which are believed to support the nervous system. In folk medicine, especially in Europe and North America, guelder rose bark (often called "cramp bark") has been used to help alleviate muscle spasms, menstrual cramps, and nervous tension. The bark contains compounds such as valerenic acid, coumarins, and various tannins, which are thought to impart mild sedative and muscle-relaxant properties. However, these effects are largely based on traditional applications and anecdotal reports rather than robust clinical studies.

Scientific research on the direct effects of guelder rose on the nervous system is limited. Most available studies focus on its antispasmodic properties, with some in vitro and animal studies suggesting that extracts may help relax smooth muscle. There is little direct evidence from human trials to confirm its efficacy for supporting the nervous system specifically. Thus, while its use for nervous system support is justified by tradition, scientific validation remains weak, and the overall quality of evidence is low. Caution is advised due to the lack of high-quality human studies.
