Q:
Is Petadolex safe and does it really keep normal blood flow in the brain?
A:

Medical guidelines recommend butterbur petasites (exclusively the patented Petadolex formulation) as safe and effective. After reviewing a decade of clinical research therapies, the Quality Standards Subcommittee of the American Academy of Neurology issued new guidelines that recommend butterbur petasites to doctors as the number-one choice for healthy blood vessel tone compared to 48 other complementary choices, several herbal, vitamin, and mineral preparations. A word of caution, though: not all butterbur products are safe. In fact, the natural butterbur root itself contains liver toxins (PAs). Petadolex is the only brand of butterbur petasites that uses a patented manufacturing process to remove PAs and deliver a pure, safe and standardized butterbur formulation. This is why it is the only butterbur used by researchers and the only one recommended by the AAN guidelines

Q:
I understand that Petadolex Butterbur Gelcaps are made from the butterbur plant as are many other herbal supplements. Are all butterbur remedies the same, or are some better or safer than others?
A:

No! Not all butterbur remedies are the same and not all of them are safe. Here's why: The butterbur plant in its unpurified powder form contains natural pyrrolizidin alkaloids (PAs) which may cause liver damage or liver cancer. PAs can be eliminated only while in a liquid form and cannot be eliminated from solid or powdered butterbur root. Only Petadolex is manufactured by a patented method for extracting the beneficial liquid of the Butterbur plant without the PAs. This purification process guarantees that Petadolex is free of detectable PAs.

Furthermore, in Europe, where Petadolex is manufactured, the special butterbur liquid extract is under strict regulation by health authorities. Therefore, Petadolex Butterbur Gelcaps must be produced so that it is 100% PA-free.
