You’re already splurging for a massage, when the therapist asks if you’d like to throw aromatherapy into the mix. Should you spring for it?

Science says it’s worth it—aromatherapy isn’t just New Age hype. These potent oils derived from plants and herbs can move your mood, or even quell pain in a matter of minutes.

And here’s the great news: you can summon aromatherapy at anytime, thanks to creative new products that suit your every need.
