The Power of Carvacrol

Carvacrol is the primary phenolic compound in oregano oil that gives it potent antimicrobial, antioxidant, and immune-supporting properties. Research shows that carvacrol can help inhibit the growth of harmful bacteria, fungi, and viruses while supporting beneficial microorganisms. Natural Factors Oil of Oregano is standardized to 80% carvacrol—one of the highest concentrations available—ensuring consistent potency and maximum effectiveness with every dose.

Why Mediterranean Oregano?

Not all oregano is created equal. Natural Factors uses only wild-crafted Origanum vulgare from the Mediterranean region, where the climate and soil conditions produce oregano with the highest natural carvacrol content. This certified organic oregano is hand-harvested at peak potency and carefully extracted to preserve its beneficial compounds, then diluted in cold-pressed organic olive oil for safe internal use.

Who It's For

Oil of Oregano is ideal for adults seeking natural immune support during cold and flu season, travelers exposed to new environments, or anyone looking to maintain respiratory and digestive wellness. It's particularly effective when taken at the first sign of seasonal discomfort or as part of a proactive immune support regimen.

Suggested Use

Take 3–6 drops 1–3 times daily under the tongue or mixed in water or juice, or as directed by a healthcare practitioner. For acute immune support, increase frequency during the first few days of seasonal challenges. Can also be diluted in carrier oil for topical use.

Important Notes

Oil of oregano is highly concentrated and may cause a warming sensation. Always dilute in liquid or carrier oil. Not recommended during pregnancy or breastfeeding. Consult a healthcare practitioner before use if you have a medical condition or are taking medications.
