Sweet Orange Essential Oil is most often referred to simply as Orange.With is versatility, affordability and wonderfully uplifting aroma, orange oil is one of the most ppopular of essential oils within aromatherapy. The aroma of orange oil is cheerful and helps to improve the aroma of a stale-smelling or smoky room. (Lemon is even better for diffusing in smoly rooms). Orange oil has become a popular ingredients within a widfe assortment of natural (some not-so-natural) Household cleaning products. I often add a few drops when I clean the floor, but I always recommend being careful when trying essential oils on surfaces for the first time and only use a few drops.
