Diffusing Essential Oils

The easiest and simplest way of dispersing essential oils into the air is to use an aromatic diffuser. A cold air diffuser uses room-temperature air to blow the oil up against a nebulizer. This breaks the oils up into a micro-fine mist that is then dispersed into the air without heating the oils which can change or damage their chemical structure and render them less effective.

The cold diffused oils, with their oxygenating molecules, will remain suspended in the air for several hours. The anti-viral, anti-bacterial, and antiseptic properties of the oils kill airborne and surface bacteria and can help reduce fungus and mold. Essential oils, when diffused, have also been found to reduce the amount of airborne chemicals and metallics as well as help to create greater spiritual, physical, and emotional harmony when inhaled.

Recommended Diffusing Time

While a diffusers can run continuously until it is out of oil, the greatest therapeutic benefit is received by diffusing oils for only 10 minutes out of an hour so that the olfactory system has time to recover before receiving more oils. This also helps to conserve your oils. A simple way to do this is to use a programmable timer that can automatically turn on your diffuser each hour for 10 minutes.

Oils for Air Purification

Diffusing essential oils in the home or work place is one of the best ways to purify our environment. The anti-viral, anti-bacterial, and antiseptic properties of the oils, along with the negative ions and oxygenating molecules that are released when essential oils are diffused, all help to reduce chemicals, bacteria, and metallics in the air.

Cinnamon bark, mountain savory, oregano, and Theives (a blend by Young Living Essential Oils), were all tested by Weber State University and were shown to kill 99.96% of the airborne bacteria present when diffused into the atmosphere.

Negative Ions

Negative ions are produced naturally by wind and rain. They help stimulate the parasympathetic nervous system which controls rest, relaxation, digestion, and sleep. If you live in a stressful environment, or an environment full of electronic equipment (which produce positive ions), the diffusion of negatively ionizing oils can help balance the ions in the air and produce a more stress free environment.

Oils that ionize negatively when diffused include: bergamot, cedarwood, citronella, eucalyptus (citriodora), grapefruit, lavandin, lavender, lemon, lemongrass, mandarin, orange, patchouly, & sandalwood.

Positive Ions

Positive ions are produced by electronic equipment and are typically found in man-made environments. They help stimulate the sympathetic nervous system, necessary for recovering, strengthening, and energizing. If you live in an environment with an over-abundance of negative ions, such as in the country or by the ocean, you may benefit greatly by diffusing positively ionizing oils.

Oils that ionize positively when diffused into the air include: clove, cypress, eucalyptus, frankincense, helichrysum, juniper, marjoram, melaleuca (quinquenervia), pine, ravensara, rosemary, thyme, & ylang ylang.

Oils for the Season: Fall/Winter

Fall and winter connote an earthy, heavy scent, rich with the traditions and memories of the holidays.

Oils that work well during this time include: cinnamon bark, pine, cedar, cedarwood, fir, frankincense, juniper, myrrh, orange, sandalwood, vetiver, nutmeg, oregano, spruce, tangerine, & thyme.


Oils for the Season: Spring/Summer

Spring and summer connote a light, airy scent, full of life, energy, and possibly a hint of romance!

Oils that work well during this time include: cardamom, citronella, coriander, eucalyptus, geranium, ginger, grapefruit, jasmine, lemon, peppermint, rose, spearmint, & ylang ylang.
