I have used essential oils for years and have
suffered no ill effects. I do not ingest the
oils and have used the same ones generally.
I would recommend testing your skin with a
drop of oil to see if you have any reaction.
I would also recommend purchasing quality oils
which will last for years and provide you with
a nice selection for everyday use. You can often
find testers for them at a good health food
store and sniff through a selection and even
try them out.
There is plenty of information online which
can help guide you in the use of oils also.
I have this book and can recommend it~~
