Dangers
The potential danger of an essential oil is generally relative to its level or grade of purity. Many essential oils are designed exclusively for their aroma-therapeutic quality; these essential oils generally should not be applied directly to the skin in their undiluted or "neat" form. Some can cause severe irritation, provoke an allergic reaction and, over time, prove hepatotoxic. Non-therapeutic grade essential oils are never recommended for topical or internal use. Essential oils should not be used with animals, as they possess extreme hepatotoxicity and dermal toxicity for animals, especially for cats. Instead, essential oils should be blended with a vegetable-based carrier oil (as a base, or "fixed" oil) before being applied. Common carrier oils include olive, almond, hazelnut and grapeseed. Only neutral oils should be used. A common ratio of essential oil disbursed in a carrier oil is 0.5–3% (most under 10%), depending on its purpose. Some essential oils, including many of the citrus peel oils, are photosensitizers, increasing the skin's vulnerability to sunlight. Industrial users of essential oils should consult the material safety data sheets (MSDS) to determine the hazards and handling requirements of particular oils. Even certain therapeutic grade oils can pose potential threats to individuals with epilepsy, or pregnant women.

Famous quotes containing the word dangers:
“Anyone with a real taste for solitude who indulges that taste encounters the dangers of any other drug-taker. The habit grows. You become an addict.... Absorbed in the visions of solitude, human beings are only interruptions. What voice can equal the voices of solitude? What sights equal the movement of a single day’s tide of light across the floor boards of one room? What drama be as continuously absorbing as the interior one?”
—Jessamyn West (1902–1984)
“The greatest dangers have their allurements, if the want of success is likely to be attended with a degree of glory. Middling dangers are horrid, when the loss of reputation is the inevitable consequence of ill success.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Fearlessness is a more than ordinary strength of mind, which raises the soul above the troubles, disorders, and emotions which the prospect of great dangers are used to produce. And by this inward strength it is that heroes preserve themselves in a calm and quiet state, and enjoy a presence of mind and the free use of their reason in the midst of those terrible accidents that amaze and confound other people.”
—François, Duc De La Rochefoucauld (1613–1680)
