Rating (out of 5): 2

Pungent Principles—often referring to the bioactive compounds found in spicy or aromatic herbs like ginger, garlic, horseradish, and mustard—have a long history of use in traditional medicine systems for supporting respiratory health, including the treatment of allergies. In Ayurveda and Traditional Chinese Medicine, these pungent herbs are believed to "open the airways," promote expectoration, and clear nasal congestion. The rationale is that their stimulating and warming properties help disperse mucus and possibly reduce inflammation in the respiratory tract, which could alleviate symptoms associated with respiratory allergies, such as sneezing, nasal congestion, and runny nose.

However, scientific validation for the use of pungent principles specifically in the treatment of respiratory allergies is limited. While some studies indicate that compounds like gingerols (from ginger) and allicin (from garlic) possess anti-inflammatory or immunomodulatory effects in vitro or in animal models, direct clinical evidence in allergic rhinitis or other allergy-related respiratory conditions is lacking. Most recommendations for these ingredients are rooted in historical and traditional use rather than robust clinical trials. Thus, while these ingredients are widely used in traditional practices for respiratory complaints, their efficacy for allergies remains supported primarily by tradition and anecdotal evidence rather than strong scientific validation.
