Some studies have shown that extracts from the root or leaves of butterbur can help symptoms of hay fever. Some people may have allergic reactions or negative side effects when using butterbur. These possible side effects include fatigue, drowsiness, headache, belching and diarrhea. The long-term safety of butterbur has not been established.

› Dietary supplements
Butterbur is commonly used in supplements as an extract from the root, the rhizome or the leaves. Raw, unprocessed butterbur products could cause harm. Only products free of pyrrolizidine alkaloids (PAs) should be used as supplements. Some studies have reported that butterbur products free of PAs are safe and well-tolerated.
