Product Details

What is Oil of Oregano (Carvacrol)?

Oil of oregano is an extract of the oregano plant, also known as Origanum vulgare. It belongs to the mint family Lamiaceae and can trace its origins to the Mediterranean. It is a popular spice around the world and features in French, Greek, Italian, Mexican, Spanish, and Turkish cuisine.

It is important not to confuse oil of oregano with the common variety used as an ingredient and flavoring for recipes. Common oregano is usually Origanum marjorana, while true oil of oregano is an extract of the Origanum vulgare plant. Oil of oregano contains many other minerals and vitamins, such as zinc, vitamin C, calcium, magnesium, niacin, vitamin A, potassium, and copper.

Potential Oil of Oregano Benefits

Oil of Oregano and the Immune System

Oregano owes much of its immunity-enhancing activity to its carvacrol contents. Carvacrol is the most abundant phenol in oregano and gives it its aroma. It also has antibacterial properties that can inhibit the growth of bacteria, yeast, microbes, and fungi. It also stops bacteria from replicating. As such, oil of oregano may boost the immune system. It also reduces food spoilage caused by microbial growth and fatty acid oxidation.

Oil of Oregano Antioxidants

Oregano is rich in potent antioxidants that can scavenge free radicals. Free radicals cause oxidative stress and damage when they outnumber antioxidants. Prolonged free radical damage can cause or worsen chronic health conditions and promote premature aging. Oregano also has a significantly higher antioxidant capacity than many other common herbs. One study comparing 27 culinary herbs and 12 medicinal herbs found that oregano has the highest antioxidant concentration. Researchers believe this is because oregano is a rich source of the antioxidant rosmarinic acid. Oregano oil also has anti-inflammatory properties. Much like unchecked free radicals, chronic inflammation can result in numerous adverse health effects.

Other Potential Oil of Oregano Health Benefits

Oregano oil may support weight loss efforts. Animal research found that carvacrol dramatically reduced the amount of weight gained from consuming a high-fat diet. Researchers believe this is because carvacrol reverses the biological sequence that forms fat cells. Oregano oil may also improve cholesterol levels. One study found that participants taking oregano distilled in water experienced a reduction in LDL (bad) cholesterol and an increase in HDL (good) cholesterol. These results are notable, as the oregano group outperformed the placebo group that attempted to lower cholesterol by making dietary and lifestyle changes. Additionally, oil of oregano may support a healthy gut.

How to Take Oil of Oregano

Oil of oregano is highly concentrated, and individuals should dilute it with a carrier like olive oil before taking it. For best results, dilute 1-2 drops of oregano oil in a teaspoon of carrier oil. Individuals can also 1-10 drops of oregano oil if the taste is too strong. Some sources recommend taking a week-long break from oil of oregano after every three weeks of use; however, the research regarding this is mixed.

CAUTION! Pure oil of oregano is very caustic and will burn or irritate tissues! Always dilute before use.

Did You Know?

The term oregano and marjoram are synonymous in many middle eastern countries.

Potential Side Effects of Oil of Oregano (Carvacrol)

While oregano oil has many benefits, it has a few possible side effects. One is reducing the body’s ability to absorb iron. Individuals should take iron supplements alongside oil of oregano to attenuate this issue. Some individuals may experience stomach upset while taking oil of oregano. Individuals with thyme, basil, mint, or sage allergies may be sensitive to oil of oregano. Discontinue use and consult a physician if any skin irritation, rashes, or vomiting occurs. Women who are pregnant or nursing and individuals taking lithium should not take oil of oregano. Individuals taking blood thinners or medication for diabetes should consult a physician before taking oregano oil, as they may interact.

Oil of Oregano + UTIs

Oregano oil exerts antibacterial effects against strains of Escherichia coli (E. coli), which causes up to 90% of UTIs. It’s also effective against Pseudomonas aeruginosa, another known bacteria that causes UTIs.

Oil of Oregano + Colds

Oregano oil has analgesic properties that may improve the pain associated with colds, such as sore throat.

Purity and Concentration of Oil of Oregano (Carvacrol)

PureBulk’s oregano oil is true Wild-Grown Mediterranean Oil of Oregano imported directly from Turkey, where it is cold-pressed and steam-distilled from the leaves and branches of the plant. Oil of oregano has a yellowish to reddish-yellow color and a characteristic spicy odor. It is insoluble in water but is soluble in alcohol and carrier oils.
