Peppermint

Simply breathing the delightful scent of peppermint essential oil, a mix of spearmint (Mentha spicata) and water mint (Mentha aquatica), may aid in the enhancement of energy, mood, athletic performance, and alertness. Several studies have found that breathing peppermint essential oil improves alertness, memory, and vitality.

One research with 144 participants discovered that smelling peppermint essential oil improves attentiveness and memory. Peppermint essential oil is quite safe. However, you should never swallow an essential oil unless you have spoken with your healthcare practitioner beforehand since too much peppermint essential oil can be hazardous.
