Butterbur Side Effects
People may think that because butterbur is a "natural" product, it is free of side effects. However, any natural product that has the capability to have medicinal properties is also likely to have side effects. Butterbur may cause fatigue, headaches, and diarrhea. If you are using butterbur and experience serious side effects (such as rapid weight gain or difficulty breathing), notify your healthcare provider right away.
Does Butterbur Cause Side Effects?Even though it is a natural product, butterbur may cause side effects. People often assume that natural products are always safe and free of side effects. However, this is simply not the case. It is reasonable to assume that any natural product with the capability to have medicinal properties may also have side effects.

Natural butterbur contains toxic alkaloids that can damage the liver and the lungs.

Liver problems are not expected to be side effects of butterbur products that are free of toxic alkaloids.
