So, what exactly is oregano oil? Whenever people talk about the oregano herb, it is usually about the universally popular spice used in Italian cuisine like pasta and salad dishes. This versatile herb has gone from the kitchen and into the medicinal world to become a herbal oil with incredible healing properties.
What Oil of Oregano Is
Oil of oregano is derived from the wild oregano plant, a member of the Lamiaceae or mint family. This plant grows in great numbers in the mountainous regions of Asia and Europe, particularly in the Mediterranean area. The oil is extracted from the dried leaves and flowers of mature plants through steam distillation method. Of the more than 40 species of oregano, the oil derived from Mediterranean wild oregano (Origanum vulgare) is found to be most healthfully beneficial. For treating disorders, oil of oregano can be applied to the affected area, taken orally, sublingually (under the tongue), or inhaled in aromatherapy. However it is administered, you can expect to see a remarkable line-up of benefits.

How Does Oil of Oregano Work?
Oregano oil contains various chemical components that work in synergy to create the antifungal, antiviral and antibacterial effect it is known for. Of these, the primary component is carvacrol which provides a lot of healing benefits. As an antimicrobial, carvacrol can penetrate tough cell membranes that bacteria use to hide from the body’s auto-immune defenses. Given its potent antibiotic action, oregano oil is not intended as a long-term medication. It is recommended to be used for only seven to ten days and taken in regulated doses.
Components of Oregano Oil
Oil of oregano possesses powerful antimicrobial properties through the presence of natural phytochemical compounds called phenols. They are known to have antioxidant effects.
This phenol fights a host of bacterial infections like staphylococcus, E. coli, Candida albicans, salmonella, campylobacter, the aspergillus mold, giardia, pseudomonas, listeria, and klebsiella.

How Safe is Oil of Oregano?
Oregano oil is safe as long as you use it as directed. If taken orally, it needs to be diluted in water or juice and thinned out with carrier oils like olive, coconut, or almond oil if applied topically. Test yourself first if you are allergic to oregano oil by applying a diluted drop of the oil on your arm and observe if any reaction occurs. Not all oregano oil is created equal. Hence, you need to be watchful of the many brands of oregano oil sold in the market. Many of them could be adulterated and may not have the therapeutic value that you paid for. Be sure that the oil of oregano that you are buying is manufactured from the Mediterranean variety Origanum vulgare or the Spanish variety Thymus capitatus. These oils are golden to dark yellow in color and have a strong herbal scent.
What Healing Solutions Can Oregano Oil Provide?
As a Treatment for Herpes
The powerful active component carvacrol in oregano oil actually breaks down the thick cell membrane that protects the herpes virus.

This is covered fully in Using Oregano Oil To Treat Herpes.
As a Treatment for Cold Sores
The red, swollen, and frequently painful blisters of cold sore are caused by the Herpes Simplex Virus 1 (HSV-1). The blisters generally appear around the mouth and on the lips. Unlike standard antibiotics that are next to useless, oregano oil can pass through the tough cell membrane and destroy the viruses that live inside the cell itself. A study conducted in 2007 showed that oregano oil is able to “disrupt the viral envelope.” The oil can be mixed with a carrier oil and used as a topical application.

The oil can be taken sublingually, inhaled directly, or through steam inhalation.
As a Treatment for Candidiasis
Candidiasis occurs when Candida, a fungus that lives inside humans, reach an abnormal growth level and create various troubles in the body.

As a Treatment for Ear Infections
An ear infection can be a painful condition when the middle ear becomes blocked due to excess fluid build-up. This can be caused by bacterial or virus infection, swollen adenoid glands, allergies, and sinus blockages. Used as a topical application, oregano oil’s anti-inflammatory and analgesic properties help lessen the pain and throbbing caused by the infection.
Heals Skin Diseases
The use of oregano oil as an external topical application can benefit individuals suffering from skin diseases like eczema, psoriasis, acne, candidiasis, rosacea, and others. Since undiluted oregano oil can cause skin irritation when used full strength, it is advised to thin it first with carrier oils like coconut, almond, or olive oil.
