Butterbur
An herbal extract known for its effectiveness in relieving hay fever and migraine symptoms.
Also known as: Petasites hybridus • Butterbur for Allergies
Overview
Butterbur is a plant that has been used for centuries in traditional medicine. Its extracts, particularly from the root, contain compounds called petasins, which are believed to be responsible for its therapeutic effects. Butterbur is most well-known for its ability to reduce the symptoms of allergic rhinitis (hay fever) and prevent migraines. It works by acting as an anti-inflammatory and inhibiting leukotrienes, which are inflammatory chemicals involved in allergic reactions.
