Butterbur - What is it & How to use

What is it?

  • Butterbur is a shrub that grows in Europe and parts of Asia and North America, typically in wet, marshy ground. The name, butterbur, is attributed to the traditional use of its large leaves to wrap butter in warm weather.
  • In the Middle Ages, butterbur was used for plague and fever, and in the 17th century it was used to treat cough, asthma, and skin wounds. More recently, it has been used for urinary tract symptoms, stomach upset, headaches including migraines, allergic rhinitis (hay fever), and other conditions.
  • Commercial butterbur products that contain extracts from the root, rhizome (underground stem), or leaves of the plant are available. Raw, unprocessed butterbur products, such as teas, should not be used because they contain harmful substances.
  • Based on two high-quality studies, the American Academy of Neurology and the American Headache Society have endorsed the use of a butterbur extract made from underground parts of the plant, like the root or rhizome, to reduce the frequency of migraines.
  • Some studies of butterbur root or leaf extracts suggest that they may be helpful for symptoms of hay fever (allergic rhinitis).
  • Butterbur has not been proven to be helpful for allergic skin reactions or asthma.

Safety Concerns

  • The raw, unprocessed butterbur plant contains chemicals called pyrrolizidine alkaloids (PAs). PAs can cause liver damage and can result in serious illness. Only butterbur products that have been processed to remove PAs and are labeled or certified as PA-free should be used.
  • Several studies, including a few studies of children and adolescents, have reported that PA-free butterbur products are safe and well tolerated when taken by mouth in recommended doses for up to 16 weeks. The safety of longer-term use has not been established.
  • Butterbur is usually well tolerated but can cause side effects such as belching, headache, itchy eyes, diarrhea, breathing difficulties, fatigue, and drowsiness.
  • Butterbur may cause allergic reactions in people who are sensitive to plants such as ragweed, chrysanthemums, marigolds, and daisies.
  • Butterbur should only be given to children under the supervision of a qualified health practitioner.
