Oil of oregano comes from wild oregano leaves (Origanum vulgare) and is traditionally used to support the immune system.* Black seed oil is pressed from the seeds of Nigella sativa and has been used for centuries in Middle Eastern, South Asian and North African traditions for general wellness.* Both are used to support the body's natural defenses, so many people take them as a daily pair.* To learn how to combine them, see How to Take Oil of Oregano with Black Seed Oil.
How to choose a quality oil of oregano
- A stated carvacrol percentage. Carvacrol is the main active compound in oregano oil. A label that states the percentage (for example 75% carvacrol) lets you compare products. No percentage means you can't tell how strong it is.
- Wild oregano (Origanum vulgare). Check the species. Some products use other plants sold as "oregano" that contain less carvacrol.
- Already diluted in a carrier oil. Pure oregano essential oil is very strong. Oil of oregano for internal use should be diluted in a carrier oil (such as olive oil) and come with clear directions.
- A dropper bottle in dark glass. Amber or dark glass protects the oil from light and makes small, measured doses easy.
How to choose a quality black seed oil
- Cold-pressed. Cold pressing uses no heat or chemical solvents, which helps keep the oil's natural compounds intact. Avoid "refined" oils or products that don't say how they were made.
- 100% Nigella sativa. The only ingredient should be black seed oil, not a blend with cheaper oils.
- Taste and smell. Real cold-pressed black seed oil is peppery and slightly bitter, with a strong aroma. A bland oil may be old or diluted.
- Dark bottle and an expiry date. Like all natural oils, black seed oil can go rancid. Check the date and store it away from heat and light.
Liquid or softgels?
Both oils come as liquids and as softgels. Liquids let you adjust the amount and are usually better value; softgels are tasteless and easy to travel with. For a side-by-side comparison, see softgels vs liquid.
