Cinnamon essential oil can be used for cooking and baking. You can try replacing a quarter cup of your normal cooking oil with a quarter cup of cinnamon oil for your culinary needs. You can also use the oil as a salad dressing to impart a unique flavor.
You can also use the oil as a mosquito repellent. Some studies show it can destroy mosquito eggs (23). Simply mix ¼ teaspoon (24 drops) of the oil for every 4 ounces of water. You can then spray this mixture around your home, upholstery, and plants.
