Top oregano oil uses and benefits of oregano oil for colds

With natural antiviral, antimicrobial, antifungal and antioxidant properties, oil of oregano is a great addition to any medicine cabinet.

Oil of Oregano

Oregano (Origanum vulgare) is an herbaceous plant, native to Greece and other Mediterranean countries. It has been used for its healing properties since ancient times, and is used as a seasoning agent in modern cooking.1

Oil of oregano is the essential oil, which has been extracted from the oregano plant and then mixed with a carrier oil for safe consumption. Due to the high potency of most essential oils, they are not meant to be eaten, or applied directly to the skin. Oil of oregano is considered safe for oral use because of its dilution with an edible carrier oil.

Over the years, oil of oregano has been found to include several beneficial healing properties. Throughout this article, you will learn the difference between oil of oregano, and other types of oregano oil, how oregano oil can be used, whether oil of oregano is safe, and where you can buy oil of oregano.

Difference Between Oil of Oregano, Oregano Oil, and Oregano Essential Oil

Oregano Essential Oil
Oregano essential oil is made by extracting the natural oils from the oregano plant through a form of distillation. This provides a very pure and potent extract.

Oregano Oil
Oregano oil is an edible oil, such as olive or avocado oil. The oil is filled with a dry or fresh oregano herb, and allowed to sit for an extended period until the oil becomes infused with the essence of the oregano.

Oil of Oregano
Oil of oregano is oregano essential oil that has been diluted with flaxseed or olive oil.

Perhaps the greatest difference between oregano oil, oil of oregano, and oregano essential oil is the reason they’re used. While oil of oregano and oregano essential oil are used primarily for health and wellness purposes, oregano oil is used as a cooking and flavoring agent.

Users should note that the phrase ‘oregano oil’ is often used interchangeably with ‘oil of oregano’. Any references to it in the article below are discussing oil of oregano.

Oregano Oil for Colds

Among the various health benefits offered by oil of oregano, one of the most popular is using oregano oil for cold and flu symptoms. The common cold causes symptoms such as sore throat, itchy eyes, headaches, fever, cough, runny nose, and sneezing.2

Using oil of oregano for colds is based on both anecdotal and scientific evidence. In Brazil, the herb has been traditionally used for its purported oregano oil antibiotic effects, particularly for respiratory symptoms such as cough, bronchitis, and sore throats.3

Did You Know: Oregano belong to the Lamiaceae plant family, which includes over 7,000 species including rosemary and thyme.12

Oregano oil sore throat remedies do have scientific merit, as noted by a 2011 study which focused on the antiviral properties of oregano oil. When tested against human respiratory syncytial virus (the cause of respiratory infections), oregano oil inhibited the virus, making it a possible alternative to over the counter cold medicine.2

Another 2011 study testing the essential oils of five Sicilian plants, found that oregano was successful as an antimicrobial agent, and had broad antioxidant effects. These results suggest that using oregano oil for colds may be useful as a preventative treatment.4

Other Oregano Oil Benefits

Aside from its use as a cold treatment, there are many benefits of oregano oil. Scientific and anecdotal evidence support the use of oil of oregano for treatment of:

1. Candida
2. Warts
3. Herpes
4. Yeast infections
5. Acne
6. Skin Tags
7. Fungus

Take a closer look at each of these ailments and how oil of oregano might help, below.

Candida is a yeast-like fungus which is created naturally in the body. When over-produced, it can cause candidiasis, which may lead to thrush in the mouth or yeast infections. Candida symptoms can affect the stomach, mouth, skin, vagina, and urinary tract, and is a common problem for individuals suffering from HIV.6

Oil of oregano has two main active constitutes, carvacrol and thymol. These two compounds are believed to be responsible for many of the oil of oregano benefits.10

According to a 2001 study, oregano oil candida treatments have the potential to be successful thanks to the oil’s strong antimicrobial and antifungal properties. The study focused on both in vitro and in vivo effects of oregano oil for candida, finding that at levels of 0.125 mg/ml, oregano oil was able to halt candida growth.5

Oregano Oil for Warts

Warts are caused by viral infections in the top layer of your skin. While there are no scientific studies promoting the use of oregano oil warts removal methods there is anecdotal evidence. It’s suggested that applying oil of oregano to the wart six times a day, and covering it with a bandage, the wart will shrink. Due to its antiviral properties, it is quite likely that oil of oregano benefits wart removal.

Oregano Oil Herpes

Another malady benefited by the antiviral properties of oregano oil is the herpes simplex virus. Oregano oil for herpes was researched in the same 2011 study.2

During the study, scientists tested the possibility of an oil of oregano herpes treatment, and found that acyclovir-resistant Herpes Simplex Virus Type 1 was inhibited by the oil. These findings suggest that oregano oil cold sore treatments could be a useful alternative to prescription treatments.2

Oregano Oil Yeast Infection

Yeast infections are caused by candidiasis and generate uncomfortable symptoms such as milky discharge, itching, and soreness.6 The candida fighting benefits of oil of oregano are well documented, making oregano oil for yeast infection a possible natural treatment.

In a 2010 in vitro study, the effectiveness of oil of oregano was tested against 16 strains of candida. Oregano was successful in halting various strains, including ones that cause yeast infections.10

Oregano Oil for Acne

One of the most common pathogens that causes acne is Staphylococcus epidermidis. Over the years, this pathogen has become resistant to antibacterial treatments.7

According to a 2007 study, an oil of oregano acne treatment may offer a natural solution for acne sufferers. Oregano oil was able to inhibit the growth of Staphylococcus epidermidis.8 Oregano oil acne treatments may be a natural alternative to harsh chemicals or peels.

Oregano Oil for Skin Tags

Skin tags are generally harmless raised stalks of skin that can appear on the neck, underarms, eyelids, neck, or inner thighs.9 One benefit of oregano oil reported in scientific research is its antioxidant property.4 Antioxidants have been found to play a prominent role in skin health. Anecdotal reports note that applying oregano oil onto a skin tag daily for six weeks may cause the skin tags to shrink and fall off.

Oregano Oil for Toenail Fungus

One of the least known health benefits of oregano oil may be its use as a natural toenail fungus remedy. Antifungal properties of oil of oregano were reported in a 2007 study, which focused on the treatment of the foot fungus, Tinea pedis. Of 11 essential oils in the study, oregano demonstrated the most effective antifungal activity.11
