Pure, unadulterated essential oils derived from the leaves, roots, seeds, flowers or bark of a plant or tree are the source extracted directly from nature via a form of steam distillation.

Lavender essential oil is quite safe for the skin, as is tea tree, but some people can have allergic reactions to them. When handling essential oils, it's wise to do a skin test. Simply apply a tiny amount on your wrist, and if there's no reaction within 24 hours you are safe. As these oils can be costly, you must take care that they're always kept in a cobalt or amber colored glass bottle and stored in a cupboard (out of direct sunlight) and kept in a cool, dry place. When you buy an oil, write the date on the product. Most essential oils can last from one to three years. Citrus oils have a shelf life ranging from six months to less than two years. Essential oils can last for several years, but the freshness disappears. There are some exceptions with the darker colored, "heavier" oils or resins. Patchouli is known to improve with age.

You should always dilute essential oils in carrier oils when applying directly to the skin. This is a necessary safety precaution. Essential oils are very strong and need to be diluted. Also, some essential oils may smell good enough to drink, but are for EXTERNAL USE ONLY!

Fragrance oils are synthesized in a laboratory. They are sometimes referred to as "nature identical." If you're looking for an inexpensive scent, then fragrance oils fit the bill. But fragrance oils are not therapeutic grade essential oils or absolutes and never will be.

Aromatherapy is a therapeutic natural practice that can be used to advance health, beauty and a sense of ease. It involves using pure essential oils with various methods, including bathing, inhalation and massage. Aromatherapy is derived from two words: Aroma means scent and Therapy means treatment. This scent/treatment has evolved over the centuries and across continents.
