Peppermint is one of the oldest and most highly regarded herbs for a number of uses. It's my personal favorite essential oil. The scent is purifying and stimulating to the conscious mind. Research has indicated that peppermint aroma may help attention, performance, and focus (Barker et al 2003). It has also been studied at Universities in regards to lessening headache pain in a double blind placebo controlled study. Peppermint is basically the bomb. It leaves your senses cool and refreshed. It can be found in our bath bombs and body butter bars.
