Oil of Oregano is a powerful plant extract with highly effective antimicrobial properties, as well as important antioxidant and anti-inflammatory activities.
 
Similar to rosemary, garlic, ginger, turmeric, and other common herbs and spices, oregano is a familiar culinary ingredient whose potential pharmacologic role can be exploited when its essential components are isolated and provided in concentrated doses.
 
The oil extracts of Mediterranean oregano (Origanum vulgare) and other varieties have a history in botanical medicine for efficacy in the gastrointestinal tract as antimicrobial, antifungal, and antiparasitic agents.
