Another great oil to use is a combo of 10 drops each Eucalyptus and Melaleuca in a 10 ml roller topped with FCO.
Once blended apply a couple swipes to the thumb of the right hand. Apply the oil to the small pit behind the ears and then drag the oil several times from the pit area, under the jaw and towards the area of the adam’s apple. Be sure to repeat the dragging action at least 4-5 times. Then repeat on the other side, applying the oil to the left thumb and then follow instructions for application as described.
Sinus infections are often associated with partially plugged eustachian tubes. This method of oil application will very often help to clear the area and allow for proper drainage.
