Goldenseal (Hydrastis canadensis) has a long history of use in traditional herbal medicine, particularly by Native American tribes and early American herbalists. It has been employed primarily for its purported antimicrobial and anti-inflammatory properties. In the context of the Eustachian tubes—which connect the middle ear to the back of the throat and play a role in ear pressure and drainage—goldenseal has traditionally been used as part of remedies aimed at addressing ear infections, sinus congestion, and catarrhal conditions affecting the upper respiratory tract. Folk medicine practitioners sometimes recommended goldenseal in teas, tinctures, or ear drops to help reduce inflammation and combat infection, theoretically supporting the health and function of the Eustachian tubes.

However, while berberine (a major alkaloid in goldenseal) does demonstrate antimicrobial activity in laboratory settings, there is minimal direct scientific research validating the effectiveness of goldenseal specifically for Eustachian tube support or related ear conditions. Most modern uses are based on extrapolations from its traditional use for mucous membrane inflammation and anecdotal reports. Therefore, its use in this context is justified primarily by tradition, and the evidence supporting its effectiveness is weak.
