7 Essential Oils That Make You Smart


Essential oils are volatile aromatic compounds which are obtained by distilling different plants. These compounds have been used for thousands for various medicinal benefits.

One of the most beneficial uses for essential oils is to improve cognitive function.

Research has demonstrated that some essential oils can improve mental accuracy and problem solving. This article will examine how these oils affect your cognition and which ones are the most powerful.

How Essential Oils Improve Cognitive Function

Researchers have found that when subjects where exposed to certain essential oils, the level of specific organic compounds increased in their bloodstream. One of those compounds was eucalyptol, which is expressed in various forms including 1,8­cineol, 1,8­cineole, cajeputol, and 1,8­epoxy­p­menthane.<

During animal testing, researchers noticed an increase in locomotor activity as the compounds entered the bloodstream. Researchers then discovered that eucalyptol based compounds suppress certain enzymes in the brain. The suppression of those enzymes, namely acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), led to increased synapse activity.

The following essential oils have been demonstrated to be useful in improving cognitive performance:
