Grab some lemon balm! The leafy plant from the mint family contains compounds that prevent the breakdown of a brain chemical linked to focus and memory. Lemon balm also contains brain-boosting quercetin and energizing caffeic acid… a combination proven to ease anxiety, and enhance problem-solving, focus, and recall. Your best bet: Place a drop of lemon balm essential oil on each palm, cup your hands over your face, and take 10 slow, deep breaths. And you’ll feel calmer, and more focused in no time!
