Some people in spring experience allergies. Allergies a reaction in your body to something and the immune system steps in to fight this invader. This substance might not be not poisonous but your body thinks it is. If you are one of these people with an allergy, you might sneeze or itch your watery eyes because of house dust, chemicals in cleaners, grasses, etc. Essential Oils can help.
Try Chamomile, Lavender, Eucalyptus, Lemon. These oils all have analgesic and antiseptic qualities and help boost the immune system. Just add 10 drops to 1 ounce carrier oil to the sinus area especially in the mornings before you head out or at night before sleep. You could also add this mixture to boiling water and inhale just like your mama told you when you were a kid. You just might feel better in no time.
