If you are inexperienced with using Essential Oils you should do a small skin patch test to assess how your body will react to the substance!
You should not apply essential oils directly to your skin. Always dilute them with a carrier oil, water, or lotion. Popular carrier oils include organic coconut oil, jojoba oil and extra virgin olive oil.
You do this by first diluting your essential oil or blend, and then spreading the mixture on roughly a 3cm x 3cm area of skin. Your inner arm is generally a good place to try this. If you don’t experience any irritation or inflammation over the next 24 hours, it should be safe for you to use the essential oil.
Inhaling essential oils is a powerful way to rid any onset of head-colds and sinus congestion. However, if you inhale them in high doses or for long periods, you may experience dizziness, a headache, and nausea. If this occurs stop immediately and seek fresh air.
Do not stuff the cotton ball into your ears as you may not get it all out again.
If you feel unwell and cannot equalise your ears, do not go diving.
If you are unsure about your ear and sinus health, always consult with a registered general practitioner.
