Media Opportunity: Dalhousie University researcher finds a new, natural approach to fight sore throat bugs

Posted by Communications and Marketing on February 1, 2021 in News

Upper respiratory infections, such as sore throats, are among the most common health problems worldwide, especially during the winter months in Canada.

The consumer demand for natural health alternatives for coughs and colds has grown quickly over the last decade as people try to find effective natural remedies for relief from the discomfort.

Researchers at Dalhousie University’s Faculty of Agriculture have discovered the plant-based essential oil carvacrol can rapidly kill Streptococcus pyogenes, the bacteria that causes strep throat. In a new paper in the Nature research journal, Scientific Reports, they outline how safe doses of carvacrol can kill this bacteria instantly through a mechanism that disturbs its cell membrane.

Doctoral candidate Niluni Wijesundara conducted part of this interdisciplinary project, which was led by the Principal Investigator, Dr. Vasantha Rupasinghe. He brought together researchers at Dalhousie’s Faculty of Medicine and Nova Scotia Health as collaborators to train graduate students and postdoctoral fellows.

Ms. Wijesundara is available to discuss her findings and how carvacrol, which can be sourced from Atlantic Canadian herbs like summer savory, could become a safe alternative for strep throat treatments and reduce the use of antibiotics that can cause harmful side-effects.
