Oregano oil improves gut health

Consuming oregano oil can aid the flow of bile into the digestive organs. As a result, this assists the digestion process. “Oregano oil’s antibacterial and antifungal properties lend to its potential to help rebalance dysbiotic bacteria and fungi in the gut,” says Amanda Frick, naturopathic doctor and director of medical affairs for Thorne Research in South Carolina. She says that the oil “is commonly tested in gut analyses for susceptibility in potentially pathogenic bacteria/fungi and may be effective against pathogens that may become resistant to antibiotics and antifungals.” In other words, if you suffer from Irritable Bowel Syndrome (IBS), Small Intestinal Bacterial Overgrowth (SIBO), or other digestive issues, you may want to explore oregano oil.

Oregano oil can help with colds

Frick explains that in addition to its antibacterial and antifungal properties, oregano oil “has been found to be effective against certain viruses.” For example, it may be especially effective against viruses that can affect the respiratory tract. “Antiviral effect along with antioxidant and analgesic properties may offer a potent trifecta against the cold and flu.” Why? Oregano oil contains thymol, a natural fungicide with antiseptic properties. Therefore, it may protect against toxins. For example, it works by helping to loosen or eliminate the buildup of mucus and phlegm in the respiratory tract. As an anti-inflammatory, it can act as a soothing agent for coughs.

According to a review in a 2016 issue of Evidence Based Complementary and Alternative Medicine, carvacrol effectively keeps food-borne pathogens like E.coli at bay. However, the benefits don’t stop there. “Oregano oil’s antibacterial properties can be effective against types of bacteria that can inhabit the digestive, upper respiratory and urinary tracts, to help fight infection,” Frick says.
