Oregano Essential Oil

Oregano Essential Oil is derived from the common Oregano herb (Origanum vulgare). Oregano is a perennial herb that is related to other common herbs, including Mint and Thyme.

Oregano Essential Oil is a popular component of many Naturopathic treatments for skin problems. Oregano Essential Oil is a common addition to topical Naturopathic acne treatments.

Several research studies have shown that Oregano Essential Oil has strong antibacterial properties, particularly against gram-positive bacteria (eg. Propionibacterium acnes). In fact, Oregano may be one of the essential oils that is most toxic to the acne-causing P. acnes bacterium. In spite of its known antibacterial activity, there has been minimal clinical research into the efficacy of Oregano Essential Oil as a topical treatment for acne. However, many individuals have reported that Oregano Essential Oil helped to improve their acne symptoms.

Oregano Essential Oil contains many molecules which are known to have antimicrobial properties and other biological activity. Oregano Essential Oil contains significant concentrations of Thymol, Carvacrol, p-Cymene and y-Terpinene. Thymol and Carvacrol in particular are known to be toxic to many types of bacteria.
