Safety precautions for essential oils

Essential oils are highly concentrated substances and should be
treated with care. A working knowledge of how to use these oils is
necessary in order that you are able to get the most benefit from
them without causing any harm. Here are a few guidelines to ensure
safe and effective use of essential oils:

· Use only 100% pure natural essential oils from plants.
· Keep oils tightly closed and out of the reach of children.
· Never consume undiluted oils. Use only oils approved for food use.

Do not use undiluted oils on the skin, dilute with vegetable oil.
There are a very few exceptions to this rule, for example non-
irritating oils like Lavender or Tea Tree oils undiluted on burns,
insect bites, pimples and other minor skin eruptions so long as you
do not have sensitive skin. You should always do a skin test with an
essential oil for sensitivity. Many people who are sensitive or
allergic to say synthetic fragrances will not be sensitive to
natural
oils. Do a patch test with a 2% dilution (with a pure vegetable oil)
in the crook of the arm; 12 hours will be ample time to check for a
reaction. If redness or irritation occurs, try a weaker dilution
(1%)
or try an alternative oil.
· Keep oils away from eyes and mucous membranes.
· If redness, burning, itching or irritation occurs, stop using oil
immediately.
