4. Antiviral Activity and Immune Support
Carvacrol and thymol also exhibit antiviral activity against several pathogens, including norovirus and herpes simplex virus. Test-tube studies show that these compounds can inactivate a significant percentage of viral particles within a short period. These findings suggest that oregano may help support immune defenses, particularly during cold and flu seasons. Nevertheless, most current evidence comes from laboratory studies, and human clinical trials are still required.
5. Potential Cancer-Fighting Compounds
Several in vitro studies have shown that oregano extracts can inhibit the growth of colon cancer cells and induce cancer cell death. The herb’s antioxidant compounds may help prevent DNA damage that contributes to cancer development. Carvacrol has demonstrated activity against ovarian, prostate, and leukemia cancer cells in laboratory settings. Animal studies also suggest that oregano supplementation may reduce tumor growth and metastasis. Despite these promising findings, human clinical trials are necessary before oregano can be considered for therapeutic cancer use.
6. Heart Health Support
Oregano may contribute to heart health by helping reduce LDL (“bad”) cholesterol levels and protecting blood vessels from oxidative damage. Its flavonoids, thymol, and carvacrol work together to support healthy lipid profiles and reduce cardiovascular risk factors. Preliminary studies also suggest benefits for the nervous system. While these findings are encouraging, additional human research is needed to fully understand oregano’s role in cardiovascular health.
7. Digestive System Benefits
Oregano has long been used in traditional medicine to support digestion. It may help relieve symptoms such as indigestion, gas, and abdominal cramping due to its muscle-relaxing properties. Research suggests that oregano oil may also help balance the gut microbiome by supporting beneficial bacteria while discouraging harmful organisms. These properties make oregano a valuable option for those seeking natural digestive support.
Overall, oregano is far more than a flavorful herb. Emerging scientific evidence supports its potential role in promoting wellness across multiple body systems, making it a valuable addition to a balanced, health-conscious lifestyle.
