Top 14 Edible Essential Oils

by Eric Madrid MD

In this article:

Since many oils are concentrated, consider 1 drop being equal to 1 teaspoon of spice or herb.  Due to their concentration, dilution is important. Do not consume directly.

It is always IMPORTANT to read the essential oil label before adding to food or ingesting.  If labeled "NOT FOR INTERNAL USE" do not consume orally nor with drink or foods.  Most essential oils that can be used internally are labeled by the FDA as GRAS (Generally Regarded as Safe). Always read the label before consuming.

Essential oils should be kept away from young children. If pregnant or nursing, consult with your healthcare provider before using. 

Since the beginning of human civilization, people have realized the benefits of essential oils. The ancient Egyptians used them during ceremonial celebrations and the mummification process, and throughout history, these oils continued to be highly valued and frequently used as fragrances, given as gifts, and even traded as currency. 

The popularity of essential oils continues in our modern times. Many people apply them topically to skin or add a few drops to bathwater while others use a diffuser to disperse the sweet aromas of these oils into work or living quarters. However, there's another great way to enjoy their health benefits: add edible essential oils to food. It's really easy and flavorful!
