Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Horseradish (Armoracia rusticana) has a long history of use in traditional medicine, particularly in European herbal practices. Historically, it has been used as a remedy for various respiratory and inflammatory conditions, including congestion, sinusitis, and infections that may cause swollen glands (lymph nodes). The root is known for its pungent compounds, especially allyl isothiocyanate, which can have antimicrobial and mild anti-inflammatory properties. Folk medicine traditions often applied grated horseradish as a poultice or consumed it in foods to "stimulate" the lymphatic system and help reduce swelling associated with infection or inflammation.

However, scientific validation for these uses is limited. While there are a few studies suggesting horseradish preparations may possess antibacterial and expectorant effects, direct evidence supporting its efficacy in treating swollen lymph glands is lacking. Most clinical research has focused on its role in respiratory infections or as an adjunct to antibiotics, not specifically on lymphatic swelling. The traditional use persists in herbalism, but modern medicine does not recognize horseradish as an evidence-based treatment for swollen glands, and it should not replace professional medical care for such symptoms. Therefore, the evidence rating for its use in this context is low, reflecting its roots in tradition rather than robust scientific support.
