Horseradish (Armoracia rusticana) has a long-standing history of use in traditional herbal medicine, particularly in Europe, for the relief of sinus-related headaches. The root is known for its pungent and volatile compounds, such as allyl isothiocyanate, which can cause a sensation of nasal and sinus clearing when consumed or inhaled. Historically, horseradish preparations have been used as a natural remedy to help "open" congested sinuses, promote drainage, and reduce the pressure that contributes to sinus headaches. Folk remedies often recommend freshly grated horseradish root, either eaten directly, added to food, or inhaled, as a way to relieve nasal congestion and thereby alleviate associated headache symptoms.

While these traditional uses are well documented, robust scientific studies validating the efficacy of horseradish for sinus headaches are limited. Some in vitro and animal studies suggest that the volatile oils in horseradish have mild antimicrobial properties and may help loosen mucus. However, there are no large-scale clinical trials directly assessing its effectiveness for sinus headache relief in humans. As a result, the use of horseradish for this purpose is primarily justified by tradition and anecdotal reports rather than strong scientific evidence. Individuals interested in trying horseradish for sinus headaches should be cautious, as its potent compounds can irritate mucous membranes in some people.
