Pure essential oils are a representation of nature in one of its most powerful forms. Harnessed, essential oils offer a world of possibilities to the knowledgeable user, but along with these possibilities comes a great responsibility. This is educational information and any opinions expressed here do not replace professional medical advice.

If you are ill, see a suitably qualified medical practitioner. Always use the best quality essential oils, purchased from a reputable company. Do not apply essential oils directly to skin, with the exception of Tea Tree and Lavender (still use with caution). Do not use essential oils if you are taking homeopathic remedies without consulting with homeopathic doctor first.

Do not use the same essential oil exclusively over a long period of time. You can become sensitive to the oil. Always blend essential oils in a well-ventilated room. Do not take essential oils internally. Always follow suggested amount, however, use less rather than more if you are unsure of amounts.

Keep essential oils away and out of reach of children. Keep essential oils away from eyes. When adding essential oil to the bath, drop directly under running water to avoid high concentration and skin sensitivity.

Essential oils are flammable and should not be stored by any open flame such as candles. We have heard of self-combustion in towels folded and stacked straight from the dryer.
