Buying Oil of Oregano – Your Guide to the Best Oils

If you’re buying Oil of Oregano, do you choose capsules or liquid?  Here you’ll learn how to choose the best oregano oil based on its active carvacrol concentrations, the purity and price, as well  as the most suitable form to get the oil in.

Since oregano oil is a natural extract produced by distilling the plant’s leaves, you’ll want to ensure the final product is safe and effective for your own use.  There are a number of important factors to look at that will ensure the oil you’re using is the right one for you.

When purchasing natural supplements you should look at the following factors:

  1. What is the Amount of Active Ingredients?
  2. What is the Plant Source?
  3. What is the Purity and Quality?
  4. What form do you want: Liquids or Capsules?

How Much Carvacrol Are You Getting?


oil of oreganoScientists have determined the oil contains two active ingredients: Carvacrol and Thymol.  It is these 2 primary ingredients that provide the health benefits of Oil of Oregano.

Research has shown that the higher the carvacrol concentration, the stronger its antimicrobial effects.Since carvacrol is one of the most active ingredients in oregano oil, you should try to use products that provide high concentrations.

The carvacrol percentages can range from 50% to over 85%;  and solutions with higher percentages of carvacrol will generally cost more than weaker solutions.

Some manufacturers will list the percentage of carvacrol or thymol you’re getting in each dose. You should avoid buying products that don’t provide this information because you won’t know the overall strength of the oil.

Some supplement manufacturers may claim the thymol level should be as low as possible. However, holistic health care practioners tend to disagree with this because thymol has been proven to have some anti-microbial properties. In fact, thymol is one of the active ingredients found in Listerine mouth wash.


Plant Sources for Oregano Supplements

Buying products that use only organically grown plants will reduce your exposure to pesticides or chemicals.

Products that come with a ‘Satisfaction Guarantee’ backed by the manufacturer is a good sign the producer stands behind their product.

Some of the higher quality oils use plants that are:

  • Grown wild on native soils

  • Handpicked

  • Pesticide and Herbicide-free

  • Are ecologically-conscious

  • Has conservation programs in place

What about Purity and Quality?

The level of purity is also important for the overall quality of the oils. Generally, the higher the purity level, the more effective the antimicrobial effects and there will be less exposure to impurities in the solution.

You can find products that use only organically-grown oregano flowers and adhere to Good Manufacturing Practices (GMP).

GMP is a set of regulations that companies follow when producing drugs, medical devices, and Active Pharmaceutical Ingredients (APIs). Many of the oils made by companies that use GMP facilities generally produce high quality products with high carvacrol concentrations.

Remember that not all manufacturers follow these practices. There are many high quality oils that are not GMP-certified so you still need to research your products.


If you’re buying Oil of Oregano based on purity and quality, you should look for the following factors:

  • Are the oils GMP-certified?

  • Is it additive-free?

  • Steam-distilled oils are higher purity

  • Free of solvents

  • Non-irradiated

  • 100% natural

  • Unprocessed and raw


Capsule or Liquid Oregano Oils

Oregano oils are available in capsules and liquid form. The liquid form is popular with consumers as this was how the oil was traditionally used. However, you will find there are a few companies that sell the oils packaged in capsules.

Below is a more detailed information on these two forms:

  1. Capsules:
    • Most capsules are made of gelatin. The gelatin can be made from animal sources or plant sources.

    • The capsules come in a variety of dosages, from 25 mg. to over 450 mg. You can get them mixed with other ‘carrier’ products such as olive oil, flaxseed oil and lecithin. The capsules are usually sold in quantities of 30, 60, and 90 capsules per bottle.

    • **Prices for capsules can range from $10 – $30.

    • These prices will also depend on the dosages, quantity and the percentage of carvacrol.

    • NOW Foods Enteric Oregano Oils is one of the most popular oregano supplements in capsule form.

  2. Oregano Liquids:
    • You can get oregano oils in liquid form. The oils may be mixed with a ‘carrier’ oil such as:

      • olive oils
      • grape seed oils
      • peppermint oils
      • capsicum oils
      • medium chain triglyceride (MCT) oils
    • **Prices for liquids can range from $20 – $50 per ounce.

    • Remember that the lowest price doesn’t guarantee you’re getting the best product. I’ve found some of the higher-priced oils are of better quality and purity, but you may find a some products that offer moderately high carvacrol percentages at a decent price.

While these products are now being marketed by large nutritional supplement companies, you can also find a variety of smaller, organic farms that produce some high quality oils.

Whichever type of product you choose, remember to compare different brands, prices and purity levels before purchasing. These simple steps will help you get the best oregano oils for you and your family.
