For nearly three decades, doctors in Germany have prescribed a standardized extract of the herb butterbur to 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.1
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 suppresses inflammatory responder cells, thus providing effective, temporary relief while supporting healthy immune function.2 Luteolin, another plant flavonoid, has been shown to help maintain normal respiratory function.3 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.4Supplement FactsServing Size:
