Synopsis

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

Pungent compounds, such as those found in ingredients like garlic, horseradish, mustard, chili peppers (capsaicin), and ginger, have a long history of traditional use as remedies for colds, particularly for their perceived decongestant effects. In many cultures, these substances have been used in home remedies to help clear sinuses and alleviate congestion—often as part of hot broths, teas, or even topical applications. The rationale is that their strong, irritating nature can stimulate nasal mucosa, increase salivation, thin mucus, and temporarily open nasal passages, providing subjective relief from congestion.

However, clinical evidence supporting the efficacy of these pungent compounds as decongestants is limited. Most studies are small, focus on subjective symptom relief, and results are inconsistent. Some research suggests capsaicin-containing nasal sprays may reduce nasal congestion, but these products are not widely used due to irritation and discomfort. The overall scientific consensus is that while pungent compounds may produce a temporary sensation of improved airflow, they do not treat the underlying cause of congestion or significantly reduce nasal swelling.

In summary, the use of pungent compounds as decongestants for colds is primarily rooted in traditional practices and anecdotal reports, with limited scientific validation. The evidence rating of 2 reflects traditional use and some preliminary scientific studies, but a lack of robust clinical trials or consistent efficacy.
