Horseradish (Armoracia rusticana) has a long history of traditional use for treating respiratory and sinus congestion. In folk medicine, particularly in Europe, horseradish root was often grated and consumed or inhaled to help clear the sinuses and relieve nasal congestion. The pungency of horseradish is due to volatile compounds called isothiocyanates, which are released when the root is crushed or grated. These compounds are believed to stimulate the mucous membranes of the nose and throat, leading to increased secretion and, potentially, the clearing of mucus blockages. Some herbalists and traditional practitioners still recommend horseradish for this purpose today.

However, scientific validation for horseradish as a treatment for sinus congestion is limited. While there are small studies and laboratory research suggesting antimicrobial properties of horseradish extracts, direct evidence supporting its efficacy in treating or relieving sinus congestion in humans is sparse. Most recommendations for its use are based on anecdotal evidence and historical use rather than on rigorous clinical trials. Adverse effects such as irritation of mucous membranes and gastrointestinal upset have also been reported, so it should be used with caution.

In summary, the use of horseradish for congestion is primarily supported by traditional practices, with limited scientific evidence to confirm its effectiveness for this specific condition.
