The Best Oregano Oil: Our Picks

Guide: Questions you should ask yourself before buying oregano oil

What does oregano oil do? - Areas of application

Oregano oil belongs to the essential oils and is also called a natural antibiotic. Oregano oil kills bacteria, germs and fungi and is also suitable for internal and external treatment. Oregano oil effectively helps with a variety of ailments, including the following:

Skin diseases

Especially in adolescence, many are affected by severe acne. Here you can use oregano oil as a natural alternative to strong medicines. First clean the affected area, then treat it with a diluted solution (1 drop of oregano oil + 10 to 20 drops of cooking oil) daily.

Gum inflammation

You can also make use of the antibacterial effect of oregano oil in the mouth and throat. Make a diluted mouthwash to use after brushing your teeth, either in the morning or at night.

Digestive problems

For digestive problems, I would use a dilution of 1:30 or 1:50 to help stimulate digestion rather than irritate the stomach.

Multi-resistant pathogens (MRE)

Multi-resistant germs can no longer be fought by medication, with oregano oil the spread can be inhibited and it can also come to the death of the pathogens.

Respiratory diseases

Due to the circulation-promoting and expectorant effect, coughing stimuli of all kinds are quenched. It is a good idea to inhale the oil with hot water, so that the valuable substances are inhaled and the stressed lungs are calmed down. The oil can even fight pneumonia, but this should be done under medical supervision to avoid damage to health.

How is oregano oil taken?

When taken orally, the oil is used in diluted form. When used pure, the mucous membranes become highly irritated, as the oil is highly concentrated in liquid form. A dilution in the ratio of 1:10 has proven to be suitable, but it can also be diluted to 1:20.

For 1 drop of oregano oil, add 10-20 drops of cooking oil (fine olive oil, rapeseed oil or coconut oil). The increased intake of oregano may lead to poorer iron absorption. This means that the body processes iron more poorly and it is a good idea to take additional iron in the form of a preparation. In order to enable a good removal of toxins, a binding substance (healing clay, zeolite, betonite) is taken as a supplement after drinking.

This enables a more efficient elimination of the dissolved toxins. Also important: drink plenty of fluids! The local application on the skin is also diluted. Simply massage in the (diluted) oil briefly, preferably after showering. It is also popular as a bath additive. The oregano bath is effective against colds, relieves cramps and eases muscle pain.

How much does oregano oil cost?

About one ton of oregano is needed to produce one litre of oil, which is why the price is correspondingly high.
Type Price
Liquid oregano oil 80-180 euros / 100ml
Capsules 20-50 euros / 100g

To be able to compare the prices of individual products, it is advisable to convert them to the same packaging size (e.g. 100ml). Of course, it is also important to know how long you will need one package. Products with 90 capsules usually supply you for 3 months, as does a 10 ml bottle (20 drops ~ 1 ml).

What side effects can occur with oregano oil?

As with any dietary supplement, side effects can occur when using oregano oil.

  • Pregnant women should keep their hands off oregano oil, as it can cause premature labour.
  • Undiluted, it can cause severe skin irritation.
  • Since oregano belongs to the labiates, rashes, swellings or similar may occur in case of allergy.

What alternatives are there to oregano oil?

Tea tree oil is also a natural essential oil. It is also very effective against skin diseases and can even be applied undiluted. The application of tea tree oil is particularly popular for warts, where it often works faster than prescription medication.

Decision: What types of oregano oil are there and which is the right one for you?

To find the most pleasant form of application for you, it is important to know both types of oregano oil:

  • Liquid oregano oil
  • Oregano oil in capsule form

What distinguishes liquid oregano oil and what are its advantages and disadvantages?

Liquid oil is very versatile. For external use, it can simply be applied to the skin. The dosage for ingestion can also be adjusted very easily.

  • Dosage
  • Also suitable for external use
  • Versatile consumption
  • Skin irritation
  • Must be diluted
  • Preparation time

The big disadvantage of using liquid oil is concentration. If you forget to dilute it or dilute it too little, severe irritation can occur depending on the skin type. Therefore, a preparation time should always be taken into account before application.

What are the advantages and disadvantages of oregano oil in capsule form?

Since no preparation time is needed when taking the oil in capsules, they are the ideal companion when travelling. Furthermore, the capsules have a neutral taste, which can be very intense with oregano oil.

  • Perfect to take along
  • Dosage according to packaging
  • Neutral taste
  • Only suitable for internal use
  • Limited use

Unlike the liquid oil, the capsules cannot be applied locally, making them of limited use for skin conditions. For those who want to use the intense oil as a spice in the kitchen or as a room scent, the liquid form is the better type of product.

Buying criteria: You can compare and evaluate oregano oil based on these factors

You can find numerous oregano oil products both online and offline. To be able to compare them better and find the best oil for you, I divide them into the following categories:

  • Production
  • Quality
  • Carvacrol content
  • Fields of application


All industrially produced oils come from water distillation. To achieve the optimal effect, look for a pure oregano oil without additives. Oregano oil can also be produced yourself. In this case, you will not get pure oregano oil, but a sunflower or rapeseed oil is used as a base.

Take a well-cleaned oregano plant and let it "infuse" for about one month in a dark and cool place. During this time, the cooking oil absorbs the valuable active ingredients of the oregano. In this way, you get a less concentrated oil that is perfect for cooking and can be used very well as a preventative.


Look for quality seals such as "organic quality", "vegan" (for capsules) and "free from additives". Organically grown oregano is free of pesticides, which is especially important if you are taking it orally. High-quality oregano oils usually come from Greece or France, also pay attention to the carvacrol content.

Carvacrol content

Carvacrol is one of the 4 active oils contained in oregano oil. Besides oregano, carvacrol is also found in thyme, savory and cress. It inhibits inflammatory reactions, prevents the spread of bacteria and also acts as a natural painkiller.

Good oregano oils usually have a carvacrol content of over 70 percent.

Areas of application

It should be decided before buying what you are going to use the oil for, so that you buy the appropriate type of product. In general, it can be said that the capsules are very convenient for internal use, while the liquid oil is perfect for external use.

Liquid oil is suitable not only for internal and external use, but also as a room fragrance. It can be used like any other essential oil.

Facts worth knowing about oregano oil

How is oregano oil produced?

As already mentioned above, the oil is produced with the help of so-called water distillation. The crushed leaves of the plant are heated in a distillation pot.

The resulting water vapour carries the extracted essential oil upwards and is passed through a cooled tube. Due to the temperature difference, it condenses and is led into a collecting basin.

Can oregano oil also be used on animals?

Oregano oil does not only work on humans, animals also benefit from the health advantages of this remedy. Due to its digestive properties, it helps the animal to digest food more efficiently. As a positive side effect, it should be noted that it also stimulates the appetite. The essential oil can also be used for diarrhoea and promises quick relief.

Is oregano oil also suitable for cooking?

You love oregano as a spice and want to try your newly bought oil in the kitchen? Go ahead, try it! Start with a small amount and add more if needed. Due to its high price and concentration, the oil is not suitable for frying, just add 1-2 drops to the finished dish.

This way you can create simple super food dishes, your body will thank you. Alternatively, oregano oil can also be added to drinks, for example, healthy smoothies.
