These info graphics are from the trusted Tisserand Institute. Robert Tisserand is one of the world’s leading experts in aromatherapy. His book, Essential Oil Safety, sets the industry and home use standards. These guidelines are for general use only and do not imply that these dilutions are safe for all essential oils in all situations.

We properly dilute essential oils to avoid adverse reactions. Skin reactions are the most common adverse reactions to essential oils, and they include:

1. Irritation (Irritant contact dermatitis)
2. Allergic contact dermatitis (delayed hypersensitivity)
3. Contact urticaria (immediate hypersensitivity)

You can read more about allergic reactions at Tisserand Institute.

Clinical Aromatherapy: The therapeutic use and application of essential oils for healing of patients based upon examination of needs and state of health.

Clinical Aromatherapist: A person trained and professionally certified in the use of essential oils for therapeutic use. 

Therapeutic Window: The lowest dose/dilution that has a therapeutic effect, and the highest dose/dilution that has no adverse effect. 

When essential oils are inhaled, the molecules stimulate olfactory pathways that are closely connected to portions of the brain’s limbic system, which influences heart rate, blood pressure, respiratory rate, memory and hormone levels. The limbic system includes the brain’s amygdala, which plays a major role in such reactions as fear and anger, and becomes highly active in emotional trauma.

Meditation: As we increase oxygen to our brain, we can initiate a relaxation response from the parasympathetic nervous system by stimulating the hypothalamus. When combined with pleasant scent, this practice can become even more powerful.

The word pure is binary. It only has two possible answers, yes or no. There is no pure, purer, purest when it comes to essential oils.

Essential oils do not have any dietary benefits (like vitamins and minerals).

Anything powerful enough to heal is powerful enough to do damage.
