According to a new study, supplementation with Curcumin (Turmeric) may reduct the duration of common cold symptoms.
99 healthy adults participated in this randomized, double-blind, placebo-controlled study which lasted for 12 weeks. The primary outcome of this study was the cumulative number of days a participant experienced common cold symptoms. Immunity, inflammatory measures, liver function and physical examination measures were all secondary outcomes. Additionally a safety assessment was also performed.
Researchers found participants who supplemented with a Curcumin supplement showed reduction in common cold symptoms when compared with participants who supplemented with a placebo. Cold symptoms like sneezing were reduced by approximately 10 days while nasal discharge symptoms were reduced by approximately 14 days, stuffy noses were reduced by approximately 11 days and finally coughs were reduced by approximately 6 days. No side effects or adverse events were seen.
Apparently Curcumin inhibited the production of prostaglandins and bradykinin (a vasodilator substance) through its anti inflammatory pathways. Additionally prior studies show that Curcumin suppresses the release of inflammatory cytokines and shows antiviral properties.
Researchers concluded that Curcumin may be important in preventing systemic symptoms caused by viral upper respiratory tract infections.
Researchers did acknowledge that the study had limitation since it relied on the self reporting of cold like symptoms which could be considered more subjective.
