Manuka Honey for Sore Throat Relief

Research suggests that the current published evidence directly examining Manuka honey for sore throat relief is extremely limited, and the single linked study does not actually investigate Manuka honey at all. That study — an industry-funded, non-clinical investigation using human respiratory cells and three-dimensional tissue models — explored the inflammatory mechanisms of pharyngitis and tested various over-the-counter sore throat remedies, finding that many popular products appeared to increase rather than decrease inflammatory markers. Because all authors were employees of the company whose proprietary product performed best in the study, the findings carry significant conflict-of-interest concerns and cannot be generalized to Manuka honey specifically. Readers interested in the evidence for Manuka honey and throat health would need to consult studies that directly examine that ingredient, as the available linked research does not support drawing any conclusions on that question.
