Goldenseal may cause changes in the way the body processes drugs, and could potentially alter the effects of many drugs. It is also known to interact with the following:

Goldenseal should not be given to infants or young children.
Before taking any new medications, including natural health products, speak to your physician, pharmacist, or other health care provider. Tell your health care provider about any natural health products you may be taking.
