Tea Tree Essential Oil
Melaleuca Alternifolia is a potent antimicrobial agent.  Because of its ability to kill off bad bacteria and at the same time soothe inflamed skin, tea tree oil is perfect for gum and tooth care. After brushing my teeth I usually rub a drop into my gums and teeth.
It also heals and soothes insect bites.

Cloves Essential Oil

Cloves essential oil is very powerful. Cloves are one of the highest valued antioxidants. The essential oil is antibacterial, antifungal, analgesic, antiseptic and anti-inflammatory. It remineralizes teeth and decreases decalcification. As it tastes very strong and has numbing properties I use it only from time to time for tooth and gum care.

For immune and antioxidant support add 1 drop of clove essential oil to 1 teaspoon of honey, maple syrup or coconut oil and drink it with a glass of lukewarm water. For further benefit pair it with cinnamon oil and poppy-seed oil.

Peppermint Essential Oil

Mentha x peperita is my pick-me-up for long road trips, rubbed gently into the area behind the ears, forehead and temples (be careful to not apply it too close to the eyes!) as it improves concentration and alertness. It also prevents nausea and helps to fight carsickness. Just sprinkle a few drops onto a cloth, hold it in front of your face and breathe deeply.
Peppermint essential oil clears the sinuses, cuts cravings and is the best natural energizer!

Frankincense Essential Oil
Boswellia carterii or serrata is known for its highly anti-inflammatory properties. I use it for skincare mixed with coconut oil in a ratio of 2 drops frankincense oil to 1 teaspoon coconut oil. The result is simply amazing, best skin treatment ever!
