Essential oils contain anti-inflammatory and anti-allergic properties which can improve your immunity and help relieve the annoying symptoms of allergies – including congestion, sneezing, coughing, and headaches. They can even help to lessen histamine production and reduce inflammation. The use of essential oils as an allergy relief option is widely accepted and many natural remedy products now include one or more essential oils as a key ingredient. As an added benefit, the aromatic properties of essential oils can also help to relax and soothe the mind.
