Source of validity: Traditional
Rating (out of 5): 2

Horseradish (Armoracia rusticana) has a long history of traditional use for treating respiratory conditions, including bronchial congestion. In herbal medicine, horseradish root has been valued for its pungent, volatile compounds—primarily allyl isothiocyanate—which are believed to act as natural decongestants and expectorants. Folk remedies have used freshly grated horseradish, sometimes mixed with honey or vinegar, to clear nasal and bronchial passages, reduce mucus buildup, and ease breathing. The mechanism is thought to involve local irritation of the mucous membranes, stimulating secretions and promoting the thinning and expulsion of mucus. While traditional use is well-documented in European and some Asian herbal texts, scientific validation for horseradish’s efficacy in treating bronchial congestion is limited. There are a few small clinical studies and laboratory data suggesting mild antimicrobial and mucolytic effects, but large-scale randomized controlled trials are lacking. The evidence that does exist points to potential benefits, but these have not been rigorously confirmed. As such, horseradish remains primarily a traditional remedy, with a modest evidence base (rated 2/5) supporting its use for bronchial congestion relief. Caution should be exercised, especially for individuals with gastrointestinal or thyroid conditions, due to horseradish’s pungency and potential irritant properties.
