Have you ever walked into a room when someone is pealing an orange and detected the familiar orange aroma wafting throught the air? What you are smelling is the natural essential oil that is housed within the rind of the orange. It is the rinds of citrus fruits that gives them their highly aromatic and familiar aroma. Although the majority of commercially available essential oils are extracted from the original botanical material by use of steam distillation, most citrus essential oils are extracted by pressing the rinds of the citrus fruits. The next time that you eat an orange or a grapefruit, take a portion of the peel and squeeze it in half ensuring that the colorful side of the peel is on the outside. If the fruit is fresh and healthy, you should notice that the rind squirts a tiny quantity of an aromatic fluid. That fluid is the essential oil.
Citrus Essential Oils are often thought of mostly for light, summery aromas, but I love using citrus essential oils all year round. My use of the citruses actually increases during the colder months as they are energizing and help to uplift the spirits. They are the perfect complement to blends that fight off the winter blues, "cabin fever" and depression. For Winter Blues recipes, visit AromaWeb's Winter Blues Recipe page.
Citrus Essential Oils are also a must to have within your apothecary when experimenting with natural fragrance blends for men or women. Most of the citrus oils are generally regarded as top notes and help lift an aroma and brighten more earthy, deep aromatics like Patchouli, Vetiver and Rose. The exception is the highly floral Neroli Essential Oil which I personally consider a middle note.
