Oil of oregano is made from the leaves of wild or Mediterranean oregano plants and usually sold in a carrier oil, either as liquid drops or as softgels. It's a popular herbal supplement on Amazon, and a very strong-tasting one. We compared listings and customer reviews to pick four options. We didn't test them. This guide sticks to what each product is and how the label says to use it. It doesn't cover what oregano oil might do for your health.
Looking for other natural supplements? See our main roundup, Best Natural and Organic Supplements, which includes Oreganol P73.
Oregano oil is strong. Dilute it and follow the label. Never take undiluted oregano essential oil by mouth unless the label specifically says to. Keep it away from your eyes and out of reach of children.
Talk to your doctor first. Ask your doctor or pharmacist before using oregano oil if you're pregnant or nursing, take medication, or are allergic to plants in the mint family.

Garden of Life Organics Oil of Oregano Drops (1 fl oz)
Garden of Life's drops deliver oregano oil in organic extra virgin olive oil, with mixed tocopherols from non-GMO sunflower. The listing says the product is USDA Organic, Non-GMO Project Verified, vegan, gluten free and kosher, as well as alcohol-free and water-extracted. The directions are simple: dilute 6 drops in water.
The 1 fl oz bottle is small. It's a good starting point if a certified organic label matters to you.
Carlyle Organic Oil of Oregano Liquid Drops (2 fl oz)
Carlyle's liquid drops come in a bigger 2 fl oz bottle. The listing describes the oil as Mediterranean and wild harvested, labels the product organic, and calls the formula vegan. It states 34 mg of organic oil of oregano per serving. Carlyle also lists it as free of gluten, wheat, artificial flavor, artificial sweetener and preservatives.
As with any oregano drops, mix them into water or juice according to the label.

Check price on AmazonNatural Factors Oil of Oregano (2 fl oz)
Natural Factors lists more production details than most. The listing says the oil is steam distilled with at least 80% carvacrol, and that every batch is third-party tested. The bottle holds 375 servings. The label suggests 4 drops in the mouth or mixed with water, or as a physician directs, and warns that you may feel a sensation of warmth.
Because it's so concentrated, mixing it with water is the more comfortable route for most people.
Carlyle Oil of Oregano Softgels (150 count)
If you'd rather skip the taste and the measuring, softgels are the simplest option. Carlyle's delayed-release softgels come 150 to a bottle. The listing says they're laboratory tested and free of gluten, wheat, yeast, milk, soy, artificial colors, flavors and preservatives.
They aren't labeled organic. If certification matters most, go with the Garden of Life drops.
How to choose oregano oil
- Drops or softgels? Drops let you adjust the amount but taste strong. Softgels are pre-measured and easier to take.
- Check the carrier. Most liquid products are already blended with a carrier oil like olive oil. Undiluted essential oils are a different product and need extra care.
- Look for real labels. Garden of Life lists USDA Organic and Non-GMO Project Verified. Natural Factors lists third-party batch testing.
- Read the directions closely. Serving sizes vary by brand, from 4 drops to 6 drops to one softgel.
- Dilute every time. Follow the label for water or juice, and stop if it's uncomfortable.
FAQ
What's the difference between oregano oil and oregano essential oil? Supplement oregano oil is usually blended into a carrier like olive oil and labeled for oral use. Pure essential oil is far more concentrated and often isn't meant to be swallowed.
Do I need to dilute oregano oil? Yes. Follow the label. Garden of Life, for example, says to dilute 6 drops in water.
Drops or softgels: which is easier? Softgels, if you don't like the taste. Drops are more flexible but strong.
What carrier oils do brands use? Garden of Life uses organic extra virgin olive oil. Check each label for the carrier used.
