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

Isothiocyanates are compounds found in cruciferous vegetables such as mustard, horseradish, and wasabi. Their use for treating or relieving sinus congestion is primarily rooted in traditional and folk medicine practices. For centuries, preparations containing isothiocyanates—such as mustard plasters or horseradish poultices—have been used in various cultures to help open nasal passages and relieve sinus congestion. The pungent, volatile nature of isothiocyanates can induce a sensation of airway clearing, likely due to irritation of mucous membranes leading to increased nasal secretions and a temporary perception of symptom relief.

While some laboratory studies have shown that isothiocyanates possess antimicrobial and anti-inflammatory properties, there is minimal scientific evidence specifically validating their efficacy for sinus congestion in humans. Most of the support comes from anecdotal reports and traditional usage rather than rigorous clinical trials. Therefore, the evidence level supporting the use of isothiocyanates for congestion is rated as 2, reflecting weak scientific support but established traditional use. People interested in such remedies should exercise caution, as the strong irritant properties of isothiocyanates can cause discomfort or even harm if used improperly.
