A Natural Powerhouse with Cautions

Wild oregano oil—derived from Origanum vulgare—is one of nature's most renowned remedies. Touted for its powerful anti-inflammatory, antiviral, and antimicrobial properties, it's often used topically or internally to support everything from skin health to digestion.

How It’s Made & What’s Inside

This potent oil is extracted through steam distillation of oregano leaves and flowers, and is rich in natural compounds such as phenols, terpenes, thymol, rosmarinic acid, and especially carvacrol—the major active ingredient known for its strong antibacterial, antiviral, and antifungal effects. It also contains vitamins A, C, E and minerals like zinc, iron, magnesium, and calcium.
