The molecules of essential oils can have a very profound physiological and psychological effect because they go directly to the limbic system of the brain which controls memory, emotions, stress levels, hormone balance, heart rate, blood pressure, and sex drive. Because of the impact on the limbic system, essential oils have been used to control the symptoms of many types of neurological emotional, or behavioral problems, including autism, ADD, and hyperactivity.

Anxiety, depression, fear, anger, and joy all emanate from this region of the brain. Since inhaling oils is such a non-invasive remedy, teachers and school bus drivers have found that they work very well in the classroom or any place where students gather. Studies show that oils such as vetiver, patchouly, cedarwood, sandalwood and frankincense can increase levels of oxygen in the brain that may lead to a heightened level of activity which can have dramatic effects on emotions, learning, and attitude as well as immune function, hormone balance and energy levels.

Various universities have experimented with oils and found that the ability to learn and to retain information can be increased by 15 to 50 percent with therapeutic quality essential oils. One study showed that inhaling peppermint oil increased the mental accuracy of the students tested by 28 percent. A Japanese company found that key-boarding errors fell by 54 percent when workers inhaled lemon.

Oils diffused in a crowded classroom can also reduce absenteeism by reducing the exposure to communicable diseases such as colds and flu.

The oil molecules can be inhaled by using a diffuser, an aroma fan, or simply by putting a few drops in the palm of the hand and cupping it over the nose. Many students are finding that an easy and convenient way to get their oil “fix” during school hours is to carry several Whiffer™ Aroma Pendants filled with peppermint, Thieves™ or other favorite oils. They can mix and match or select a diffuser pendant according to their need at the time. Do not use any method that requires heat because that will fracture the molecule and decrease the effectiveness of the oil.
