Oregano oil is the most potent natural anti-inflammatory and antibacterial agent ever discovered by mankind. It is extracted from the wild plant oregano, which grows mostly in the Mediterranean region of Greece and Portugal, and is the number one herbal remedy of the Greeks. Hippocrates, the father of world medicine, stated that oregano oil has antiseptic and antibacterial properties, relieving gastrointestinal discomfort and respiratory problems. As early as the Middle Ages, oil of oregano was used as an antiseptic, and was also used to preserve food.
