Orange is the most commonly grown fruit tree in the world. Our orange essential oil is cold-pressed from the skin of citrus sinensis trees grown in the USA. Orange essential oil is great for lifting the spirit and clarifying dull skin. Apply to the abdomen to ease painful swelling from indigestion. Diffuse or apply topically in 2-5% dilution. Sweet Orange Essential Oil has a sweet, citrus smell much like the orange peels it is derived from, only more intense and concentrated.
