Sweet orange essential oil comes from Citrus sinensis, the oranges you are used to eating. It is derived from the fruit, especially the rind. It is mostly used in aromatherapy but has been studied for topical application (applied to the skin).
According to aromatherapy practitioners, inhaling essential oil or absorbing it through the skin transmits messages to the limbic system. This is a region of the brain that helps process emotions and regulates the autonomic nerve system, which is responsible for things like heart rate, blood pressure, respiration, and gut motility.
Proponents claim that using orange essential oil in aromatherapy can help treat or prevent the following health conditions:
- Colds and flu
- Skin Care
Breathing in the scent of sweet orange essential oil may help alleviate anxiety, suggests a 2012 study in the Journal of Alternative and Complementary Medicine. The study, involving 40 male volunteers, looked at the effects of sweet orange essential oil when inhaled at different concentrations (2.5, 5, and 10 drops).
Stress was then measured using the Stroop Color-Word Test, which measures the speed by which a person can read words or identify colors. (Increased cognition is generally recognized as a marker for stress alleviation.)
