It should first be noted that you should NOT follow the directions they provide on their website. According to DoTERRA set of instruction you should dilute these essential oils in water, tea or shakes. But internal consumption of essential oils is a very risky thing and you should definitely consult a certified aromatherapist before even attempting to do so. These oils are hydrophobic as well so they will simply float on the surface of your drink and no one likes that. The best way to use them is to mix with other vegetables oil (olive, jojoba, sweet almond, etc.) and apply on the skin of the abdomen, throat or the feet. You can simply inhale them as well.
