Butterbur acts on migraine headaches in two ways. It removes painful migraine headache symptoms by lowering the inflammatory effect of chemicals like leukotrienes and prostaglandin E2. The second active benefit found in butterbur is its ability to function as a natural beta blocker whose action results in the normal flow of blood to the brain. This helps control blood pressure and spasmodic capillary action, which can also contribute to the onset of migraine headaches.
Wondering how well butterbur works? In a study of 245 people conducted by the Department of Neurology at Albert Einstein College of Medicine, 68% of participants saw the incidence of migraine headache symptoms reduced by at least 50%. This is a huge breakthrough for people suffering from migraine headaches and the results are better than those of many dangerous over-the-counter and prescription medicines
