Amrita Aromatherapy sources Certified Organic Sweet Orange Essential Oil from here. This is a very uplifting oil. Pesticides are commonly oil soluble but not water soluble. Since citrus oils are cold-pressed rather than steam-distilled, pesticides tend to end up in the oil. Therefore, we strongly recommend you use organic citrus oils rather than those from conventional farming. The price difference between the conventional and the organic is rather small. Amrita therefore carries only the certified organic oil.
