Frequently Asked Questions

What is aromatherapy?

Aromatherapy is the practice of using aromatic essential oils - highly concentrated extracts from the flowers, leaves, bark, peel, resin, or roots of plants. These natural aromas have been valued and enjoyed in personal and cultural rituals for thousands of years.

How are essential oils used?

Because essential oils are highly concentrated, use them by the drop and with care. As a general rule, dilute before applying to skin. They can be diluted in carrier oils, lotions, and hair care; added to a bath; diffused in the air with a diffuser or aroma lamp; or added to water in a spray bottle. You can also blend oils with similar characters to create your own aromas.

How long do essential oils last?

Most will keep about one to two years, or longer, if properly stored. Keep them in a tightly closed bottle in a cool, dark place - heat causes oils to evaporate and light alters them over time. Citrus oils are the exception and begin to oxidize after about a year; refrigeration or a little vitamin E extends them. A few oils, such as patchouli, vetiver, and sandalwood, only get better with age.

What is steam distillation?

Steam distillation is the most common extraction method. Plant material is placed in a still and exposed to concentrated steam, which releases the oil. The aromatic steam then passes through a tube cooled by cold water and condenses back to liquid; because of the difference in weight, the oil and water separate and the oil is drawn off. The water collected is called a hydrosol, or floral water. Quality depends on the plant material, the equipment, and the skill of the distiller.

What does cold pressed mean?

Typically used for citrus, cold pressing mechanically presses the oil out of the fruit rind. It's also known as "expression."

What is an absolute?

The delicate fragrance of some flowers can't survive steam distillation's heat, so other methods are used. An absolute is one of them: flowers are immersed in a solvent to produce a waxy "concrete," which is then processed to yield a thick, intensely aromatic oil called an absolute.

Can I use essential oils internally?

No. We never recommend internal use of essential oils. They are highly concentrated, can be irritating to skin and mucous membranes, and may be harmful if swallowed. We recommend diffusion, or topical use after diluting 1-3% in a carrier oil.

Is it safe to use essential oils during pregnancy?

If you are pregnant or nursing, please talk with your healthcare provider before using essential oils.

Are essential oils safe for children or the elderly?

Children, older adults, and anyone with sensitivities should use extra care and a lower dilution. If you have any questions about a specific situation, check with a healthcare provider first.
