Rating (out of 5): 2

Curcumin, the active component of turmeric (Curcuma longa), has garnered scientific interest for its potential role in managing respiratory allergies, such as allergic rhinitis and asthma. Several preclinical studies have demonstrated that curcumin exhibits anti-inflammatory and immunomodulatory properties, which may help alleviate symptoms associated with respiratory allergies. Curcumin is known to inhibit the release of histamine from mast cells, reduce eosinophil infiltration, and downregulate pro-inflammatory cytokines (such as TNF-α and IL-4), all of which are implicated in allergic responses.

Some small-scale human clinical trials have also been conducted. For example, a randomized, double-blind, placebo-controlled study published in 2014 in the journal Annals of Allergy, Asthma & Immunology found that curcumin supplementation improved nasal airflow and reduced sneezing and nasal congestion in individuals with allergic rhinitis. However, these clinical studies are generally limited by small sample sizes and short durations, and further robust, large-scale trials are needed to confirm efficacy and establish dosing guidelines.

While curcumin is not a mainstream or first-line treatment for respiratory allergies, its favorable safety profile and mechanistic plausibility have made it a subject of ongoing research. Overall, there is preliminary scientific evidence supporting its use as an adjunct therapy for respiratory allergies, but the current evidence base is moderate at best, warranting a rating of 2 out of 5.
