Question 6

Does Butterbur interact with medications or other supplements?

Accepted Answer

Butterbur may interact with certain medical conditions. Always inform your healthcare provider about all medications and supplements you are taking.

Question 7

Is Butterbur FDA approved?

Accepted Answer

Regulatory Classification

In the United States, Butterbur is marketed as a dietary supplement. Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), this compound is regulated as a category of food rather than as a pharmaceutical drug. Consequently, the ingredient does not undergo the rigorous pre-market testing or approval process required for prescription or over-the-counter medications.

FDA Oversight and Manufacturer Responsibility

The Food and Drug Administration (FDA) does not review these products for effectiveness or safety before they are made available to consumers. Instead, the responsibility for ensuring that the product is safe and that any claims made on the label are truthful and not misleading rests primarily with the manufacturer. The FDA is generally authorized to take action against any adulterated or misbranded supplement only after it has reached the market.

Quality and Purity Standards

Because it is regulated as a supplement, the quality, purity, and consistency of it can vary significantly between brands. While some manufacturers voluntarily adhere to strict processing methods to remove toxic pyrrolizidine alkaloids (PAs), there is no federal requirement for the FDA to verify the removal of these substances or the overall purity of the extract prior to distribution.

Question 8

Where can I buy Butterbur?

Accepted Answer

Retail and Online Access

Butterbur is commonly available for purchase through a variety of retail outlets. Consumers can typically find this ingredient in brick-and-mortar locations such as specialty health food stores, vitamin shops, and some pharmacies.
