Background on butterbur
Butterbur is a shrubby plant from the sunflower family that boasts large rhubarb-like leaves and thick creeping roots. This plant grows naturally along riverbanks and marshes throughout Europe and Asia. For more than 2000 years, butterbur has been used to address conditions ranging from pain, fever, spasms and headaches.
In 1988, PA free butterbur was officially recognized by the German government as a legitimate prescription for migraines. This verdict was based on German clinical trials demonstrating that the use of butterbur for migraines may reduce incidence by 50% among long time migraine sufferers (Diener, 2004; Grossmann, 2000; Lipton, 2004; Pothmann, 2005).
In this article, we discuss the biological basis for the effect of butterbur on migraine headaches. At the end of the article, we discuss factors to consider when choosing a butterbur supplement.

Butterbur is a promising alternative remedy for migraine sufferers.
Clinical results demonstrate butterbur’s effectiveness (Diener, 2004; Grossmann, 2000; Lipton, 2004; Pothmann, 2005). The power of this plant likely comes from its anti-inflammatory and muscle relaxing properties.
Butterbur extract contains multiple sesquiterpene compounds that decrease inflammation and relax the blood vessels inside our brain. These compounds are called petasins.
Research shows how these petasin compounds alter calcium channel interactions and shut down the inflammatory proteins, LOX and COX-2. Both of these petasin activities are linked to migraine pain relief (Eaton, 1998; Pearlman, 2001; Sheftell, 2000).
Several high-quality clinical trials have demonstrated butterbur’s effectiveness at reducing the symptoms and incidence of migraine headaches (Lipton, 2004; Pothman, 2005). A study published in Neurology reports that taking 75 mg. of butterbur twice daily is sufficient to cut migraine frequency in half (Lipton, 2004).
The authors report a 48% reduction in migraines as compared to a placebo control group (p= 0.0012).
That is a significant finding.
Based on such findings, the American Academy of Neurology (AAN) and American Headache Society (AHS) endorsed butterbur as a preventative for migraine headaches with a Level A recommendation (Loder, 2012). In 2012, the AHS and the AAN issued updated guidelines for the prevention and treatment of episodic migraines. This group reviewed a large body of published data on multiple forms of drug and supplement approaches to migraine headaches.
They determined that 6 migraines treatments were considered Level A (Divalproex/sodium valproate, Metoprolol, Petasites (butterbur), Propranolol, Timolol, Topiramate).
The Level A distinction was given for treatments for which there are at least 2 high-quality, randomized, controlled trials demonstrating efficacy. Level A status means the treatment has been ‘established as effective and should be offered to patients requiring migraine prophylaxis.’ This group included 3 beta-blockers, 2 anti-epileptic drugs and the herbal supplement butterbur (Loder, 2012).
Lastly, it should be mentioned that migraines are an extremely variable health condition and the use of butterbur may not yield successful results for all individuals (Agosti, 2006).
What factors should you look for in a quality butterbur supplement?
In general, butterbur is well tolerated by our bodies when used at recommend dosage. It should be noted that butterbur should not be taken while simultaneously taking other medications that effect liver function (for ex. carbamazepine, phenobarbital, rifamin). These liver function drugs may affect the manner butterbur is metabolized.
Choose a PA free butterbur brand
When choosing a butterbur supplement it is critical to choose a brand that is labeled ‘PA free’. Pyrrolizidine alkaloids (PA) are compounds that occur naturally in butterbur but need to be removed because they are toxic.
Your supplement should be clearly labeled butterbur PA free.
All of the butterbur supplements reviewed below are labeled ‘PA free’. Some of the supplements contain only butterbur, others include additional ingredients related to neurological health.
