Horseradish (Armoracia rusticana), with its unmistakably sharp taste, is much more than just a strong condiment. In folk medicine and phytotherapy, raw horseradish poultices are considered a first-line remedy against cough, bronchitis, rheumatic pain, pulmonary congestion, and muscle pain. Modern research confirms some of these effects, giving it a prominent place in external natural treatments.
What does horseradish contain?
- Isothiocyanates (allyl isothiocyanate) – compounds with antibacterial, antifungal, decongestant, and local irritant effects (stimulating circulation)
- Vitamin C – with antioxidant and immune-stimulating effects
- Sulfurous volatile oils – responsible for expectorant and decongestant effects
- Enzymes (myrosinase) – activate irritating substances upon contact with the skin
What do recent studies say?
Journal of Ethnopharmacology (2017): extracts from horseradish root showed significant anti-inflammatory and analgesic effects in experimental models.
Frontiers in Pharmacology (2019): volatile compounds from horseradish inhibit respiratory bacteria and stimulate local circulation, supporting the drainage of inflamed mucous membranes.
Phytomedicine (2022): local application of horseradish preparations had a rubefacient (warming) effect in cases of muscle pain and joint stiffness.
How does horseradish poultice work?
Stimulates local blood circulation (warming effect)
Calms muscle spasms and cough
Clears respiratory pathways through expectorant action
Reduces inflammation in joints and muscles
Activates lymphatic drainage and mucus elimination
