What is Oregano Oil?

The common food spice oregano grows wild in the mountains of Mediterranean countries. In ancient Greece, oregano or its essential oil was used for the treatment of wounds, snakebites, spider bites, and respiratory problems. Respiratory uses dominated the medicinal history of oregano in medieval Europe, but in the nineteenth century, physicians in the Eclectic School (a medical movement that emphasized herbal treatment) used oregano for promoting menstruation.

The symptoms of this purported syndrome include common conditions such as fatigue and headache. A succession of anticandidal treatments have been offered as treatment. Oregano oil is one of the more recent of these products.
