Uses for orange: Orange’s greatest claim to aromatherapy fame is its ability to affect moods and to lower high blood pressure. In fact, just sniffing it lowers blood pressure a couple points. It is also a good adjunct treatment for irregular heartbeat. Research at International Flavors and Fragrances, Inc., in New Jersey found that orange also reduces anxiety. You don’t even need to buy the essential oil; simply peel an orange and inhale its aroma.
