Butterbur ( Petasites hybridus) is not a commonly used herb among herbalists. I have used it on occasion for migraines. There are human studies on its use for allergic rhinitis, asthma, bladder dysfunction and prevention of gastric ulcers
A lot has been written on butterbur for migraines. There was a published systemic review in 2020 on 19 clinical trials . The studies concluded that several herbal medicines ( butterbur curcumin citron, coriander , methol and chamomile) had multifactorial physiological influence on migraines but more studies were warranted.
There was a study in 2006 using a formulation of butterbur called Petadolex for migraines. This study had statistical significance for use in migraines.
There is a major drawback and caution when using butterbur. The pyrrolizidine alkaloid more in the herbs roots than leaves has been reported to cause hepatic veno-occlusive disease. Although written I have not seen a case of hepatic veno-occlusive disease when using this herb.
I have used it for migraines with much success.
Until tomorrow…
