Oil of Oregano Health Benefits

Oil of Oregano Health Benefits

What is Oil of Oregano?

Oil of Oregano is a highly potent natural purifier that is extracted from wild oregano plants, and two key compounds found in it are carvacrol and thymol. Studies have shown that both of these compounds have significant effects on harmful micro-organisms that cause many illnesses in humans1.

It is important not to confuse Oil of Oregano with common oregano that is used as a spice for cooking. Common oregano is typically Origanum Marjoram, while Oil of Oregano is derived from Origanum Vulgare.

Oil of Oregano can be purchased as either a liquid or as capsules/tablets. In both forms, it is important to verify that the oil is derived from the proper potent oregano plant, and that the carvacrol concentration is at least 70%.

What are the Health Benefits?

The ancient Greeks were one of the first people to recognize this oil for its health benefits and medicinal qualities. It is known to be a potent antiviral, antibacterial, antifungal, and antiparasitic oil that can reduce pain and inflammation and effectively fight off infections 2.

Some of the specific benefits of this amazing oil are:

  • Destroying organisms that contribute to skin infections and digestive problems.
  • Strengthening the immune system.
  • Increasing joint and muscle flexibility.
  • Improving respiratory health.

Natural Remedies Using Oil of Oregano

Skin Infections

Oil of Oregano can be applied directly onto the skin to treat itches, skin infections, and irritated gums, but only if it has been diluted. Always follow the instructions on your particular bottle before applying topically onto the skin, since highly concentrated oils may first need to be mixed with Olive Oil or Coconut Oil before application (usually one teaspoon of Olive Oil or Coconut Oil per one drop of Oregano Oil).

Digestive Problems

The high concentrations of thymol and carvacrol in Oil of Oregano have been shown to calm upset stomachs and aid digestion. Therefore, a quick home remedy for mild indigestion is to drink a glass of milk or juice that is mixed with 2 or 3 drops of the oil.

Sinus Congestion

Oil of Oregano is a wonderful natural remedy for sinus congestion. A common solution is to add 3 drops of the oil into a glass of juice and drink this mixture daily for 3 to 5 days.

Colds and Sore Throats

Oil of Oregano is an excellent early defense mechanism when you feel a cold or sore throat coming on. Simply take 3 drops of the oil once per day (you can mix it into a glass of orange juice) and you should notice results within a few hours. Repeat this once per day for up to 5 days until the symptoms are gone.

What are the Side Effects?

While Oil of Oregano has many benefits, there are a few possible side effects:

  • It may reduce the body's ability to absorb iron. Therefore, it is recommended that any regular use be combined with regular consumption of iron supplements. For this reason, women are advised not to take this oil during their pregnancy.
  • Pregnant women should also avoid this oil since it can stimulate blood flow in the uterus, which can weaken the lining that surrounds the fetus in the womb.
  • People that have allergies to thyme, basil, mint, or sage may be sensitive to Oregano Oil as well, since they are in the same family of plants. If any skin irritation, rashes, or vomiting occurs when using it, it is recommended that you discontinue use and consult your doctor.

Where and How to Buy Oil of Oregano

Oil of Oregano can be found in almost any natural health or nutrition store, or from online retailers such as (see below). It is important to make sure that it is derived from Origanum Vulgare, and that the carvacrol concentration is at least 70%.

    @Chris, it says above on this page that the regular use of Oregano Oil can interfere with the body's ability to absorb iron. So it may cause iron deficiency. Therefore, if you are taking it for longer period of time, taking iron supplements along with it may help.

    Julia, same thing is happening to my sister in law and she has Lyme Disease. I bet that is what you have and most medical doctors just blow you off. My son has had it for 7 yrs now and it is very bad. He has chronic fatigue affecting every aspect of his young 23 yr old life! His primary blew me off - after a year of testing him for all kinds of things and now finally we have a correct diagnosis. I just learned about oil of Oregano and going to order it ASAP for him! Good luck!

    Using 4-drops of oil of oregano + 16 oz water as an enema for Fistulizing Crohn's Disease. WORKS 100% - infection was gone in 2 days. I used to use Cipro but not anymore. It is amazing how fast this oil works. Keeps me out of the emergency room and lets me have some sort of normal life. Make sure you shake it good. Start off slow (1 drop) until you know how it feels. Over 4 drops can cause pain for about 2 minutes. It's spicy.

    @ Julie Tapia, Oil of Oregano has anti-inflammatory activity, therefore, taking 3-4 drops of organic oil of Oregano once daily for 1-2 weeks may help with inflamed legs and feet. You may also try drinking Dandelion tea. Research suggests that the Dandelion plant contains flavonoids that have anti-inflammatory effects. Dandelions also have diuretic activity which helps with water retention. To learn more about Dandelion's health benefits and how to make Dandelion tea, please read this article:
    Hope it helps!

    Would Oil of Oregano help with swelling of the feet and legs? I have had for months - there is no known medical reason why my feet and legs are painful and are swelling up along with weight gain. I cannot get rid of it - even doctors do not know why it's happening. Will this oil help with this or is there anything else that you may know will help better. Each of us thank you!

    My daughter and myself both had a sinus infection and bronchitis at the same time. After two steroid shots, an antibiotic shot, and a 10 day regimen on Amoxicillin, neither one of us was any better. Our drainage & cough had actually worsened. My sister who had been battling the same thing for six weeks, went to her nutritionist for advice. She recommended taking Oil of Oregano, one gel cap three times daily after meals. She said the sinuses would clear in 5 days. After five doses, not five days, our sinuses cleared out and the bronchitis had subsided substantially. This stuff is absolutely amazing!!! We will never be without this in our medicine cabinet, ever!
    NOTE: We both had Oregano burps at first, but they went away after eating smaller meals before taking it.
