Several studies have found that thyme essential oil may help destroy lung and breast cancer cells.
Known scientifically as Thymus vulgaris, thyme essential oil contains 20 to 54 percent thymol. It falls under a group of natural substances called “biocides,” which are known for eliminating harmful organisms. In lab tests, researchers examined thyme’s antibacterial and toxic effects on three types of human cancer cells — and it showed the ability to kill lung, ovarian, and oral cancer cells.
Though thyme is native to the Mediterranean region, it was the Greeks who named it. To this day, Greek cuisine still features thyme often, especially in combination with olive oil.
One study even revealed that thyme oil could eliminate over 97% of human lung cancer cells.
Recent findings suggest that combining thyme with olive oil can further boost its anti-cancer effects. This may help explain why cancer rates in Greece are lower than in much of Europe and the U.S.
Beyond its potential anti-cancer benefits, thyme essential oil is also valued in traditional remedies for its strong antibacterial, antifungal, and antioxidant properties. A study by Celal Bayar University in Turkey examined the effect of wild thyme on breast cancer cells. Results showed that wild thyme could be a promising option for developing new breast cancer treatments.
To use thyme essential oil safely, dilute a few drops in a carrier oil, then apply it with your finger to the back of the roof of your mouth or near the area of concern. Since it’s a very strong oil, dilution is highly advised.
For oral consumption, place 1–2 drops on a spoonful of honey.
Fresh thyme also plays a role in healthy diets — it’s often used in cooking, herbal teas, and salads mixed with fruits or vegetables.
Fun fact: Orthodox Christians sometimes place thyme in bedrooms as part of spiritual practices, using it for relaxation, prayer, or to ward off bad dreams.
