For nearly three decades, doctors in Germany have used a standardized extract of the herb butterbur for their patients suffering from nasal discomfort and its related problems. Butterbur’s main active ingredient is petasin, a phytochemical that may reduce spasms in smooth muscle, thus relaxing swollen nasal membranes.115

Butterbur Extract with Standardized Rosmarinic Acid contains a patented butterbur extract. State-of-the-art technology allows for standardization of butterbur’s key active ingredients while ensuring that the extract is free of any undesirable compounds.

This formula also contains standardized rosmarinic acid, a plant polyphenol derived from rosemary leaf. Rosmarinic acid helps to regulate inflammatory responder cells, thus providing effective, temporary relief while supporting healthy immune function.116,117 Luteolin, another plant flavonoid, has potent fluid-regulating properties both in vitro and in vivo. It also has been shown to help maintain normal respiratory function.118-120 Luteolin may also protect against cytokine-induced pancreatic beta-cell damage through suppression of NF-kappaB activation.121 Also included is perilla leaf extract. When enriched with rosmarinic acid, perilla leaf extract has been shown to provide significant seasonal support for the body.122
