Essential Oils vs Aroma Oils

Most essential oils on the market are designed for aromatherapy (aroma oils), but there are also essential oils for internal use, or food-grade, that are created for their healing properties. In this article, we talk about the latter. Food-grade essential oils can also be used topically in a carrier oil, or in aromatherapy. However, the essential oils designed only for aromatherapy (aroma oils) are not the same as the healing essential oils, so do not confuse the two.

Warning! Do not confuse medicinal essential oils with essential oils for aromatherapy, which can be toxic when ingested. Use only essential oils for internal use (food-grade) as directed on the leaflet.

How to Use Essential Oils Internally


The usual dosage for most essential oils is 3-5 drops three times a day for 7-14 days, diluted in a tsp of raw honey, or on a small piece of bread (for diabetics). Pause for 2 weeks and resume if needed. For children between 7-14 years of age, the dosage is 1-2 drops three times a day with honey. These essential oils are not recommended for children under 7 years of age. Always use these essential oils diluted, otherwise, they can burn your throat. Essential oils are not supposed to taste good, so don’t expect a pleasant taste. Be careful, it may sting/irritate the throat even if diluted!

Safety & Precautions

Essential oils are not recommended for pregnant women, nursing mothers, and people who have hypersensitivity to them. They are very powerful and they can burn, so avoid eye contact! Do not overdose and don’t take them for more than 14 days straight. Always use essential oil as recommended on the leaflet.

Now let’s get to the most powerful essential oils and their amazing healing abilities.

10 Most Powerful Essential Oils and Their Uses

1. Thyme Oil

(Thymus vulgaris)

According to scientific studies, the natural compounds in thyme oil affect the cell membranes of bacteria, altering their permeability, which leads to their destruction. Thyme oil enhances the activity of some antibiotics. Thyme oil targets viruses, parasites, and bacteria in all parts of the body, which makes it one of the most powerful essential oils out there.

Weight loss aid

Known for its sweet and bitter taste, grapefruit oil is used as an antiseptic, disinfectant, and especially as a weight loss aid.

Similar to thyme oil, oregano oil contains carvacrol, an active substance with strong antibacterial properties.
