I’ve had something going on with my sinuses for over a month. I decided to try this trick, and it is working wonderfully! I heat a cup of water in the microwave until it is piping hot. I drop 2 drops each of oregano, melaleuca, lemon and peppermint essential oil into the water then inhale several times. My sinuses finally have been able to drain. The melaleuca is cleaning the biofilm off of the bacteria in my sinuses so the the oregano can enter and kill it. The lemon helps this concoction smell nice. The peppermint increases blood flow to the sinuses which helps your sinuses to drain.
Try it. Do this consistently (2 -3 times a day) and watch your sinus issues clear up. It’s amazing!
