AOR Petadolex


View all AOR products


Petadolex contains a standardized extract of Petasites hybridus (butterbur), a shrub found in Europe, Asia and North America. Its earliest recorded use as a medicine was during the middle ages when it was used to treat plague and fever; in the 17th century its use was noted in treating cough, respiratory illnesses, and skin wounds.

Today, butterbur is mostly used as a support for migraine headache sufferers due to its anti-inflammatory and anti-spasmodic activity. Clinical trials have demonstrated butterbur's effectiveness for migraine prevention, with subjects experiencing as much as a 60% drop in the frequency, intensity, and duration of migraine attacks compared to placebo groups. Butterbur is also used to support respiratory inflammation, as well as gastrointestinal disorders, and has been shown to help relieve allergic symptoms such as nasal congestion, runny nose and irritated eyes. 

One concern is that the butterbur plant naturally contains pyrrolizidine alkaloids, which are thought to potentially cause liver damage and be carcinogenic in animals; however, AOR’s Petadolex is a specific extract from Germany in which the pyrrolizidine alkaloids have been removed. Petadolex is a safe, natural alternative to over the counter medications for those who suffer from the symptoms associated with allergies and migraines.
