Life Extension Butterbur Extract (As Seen on TV)
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 inhibit leukotriene synthesis, inhibit inflammatory effector cell functions, and reduce spasms in smooth muscle, thus relaxing swollen nasal membranes.
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 contains extremely low levels (<0.1 ppm) of pyrrolizidine alkaloids.
This formula also contains standardized rosmarinic acid, a plant polyphenol derived from rosemary leaf. Rosmarinic acid helps regulate inflammatory responder cells, thus providing effective, temporary relief while supporting healthy immune function and normal respiratory function.35-38 Luteolin, another plant flavonoid, has been shown to help maintain healthy DNA and support a healthy inflammatory process.39-44 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.
