Breathe in Aromatherapy for Productivity and Peace

Aromatherapy includes using essential oils to soothe stress through scent and can be a powerful tool to boost productivity. You can choose from such great flavors as peppermint and lavender, and I have found a diffuser to be very effective in spreading the scent around my office. Do you use aromatherapy already? If so, for what needs? How can you utilize this tool for greater success?
