Deep Dive
Butterbur’s active compounds, called petasines, are the heroes here. While standard antihistamines block histamine after it is released, Butterbur works by stopping the production of leukotrienes before they cause swelling in your nasal passages. This dual-action mechanism makes it highly effective for people who find standard allergy pills ineffective or sedating. regarding migraines, it appears to reduce the sensitivity of blood vessels in the brain, preventing the painful dilation that triggers an attack.
