A Review on Benefits of Peppermint and Eucalyptus Essential Oil

Abstract

The effects of peppermint oil and eucalyptus oil preparations on neurophysiological, psychological 
and experimental algesimetric parameters were investigated in 32 healthy subjects in a double-blind, 
placebo-controlled, randomized cross-over design. Four different test preparations were applied to 
large areas of the forehead and temples using a small sponge and their effect was evaluated by 
comparing baseline and treatment measure. The combination of peppermint oil, eucalyptus oil and 
ethanol increased cognitive performance and had a muscle-relaxing and mentally relaxing effect, but 
had little influence on pain sensitivity.
