As the largest fragrance family on the wheel, herbal scents are divided into two categories: fresh and green. Fresh herbal scents are the calming, sweeter herbs. Think herbs you might turn into a creamy cup of tea, like Chamomile, or sweet herbs used to gently add flavor to a dish, like Basil. Woody Thyme also falls into the fresh category. Green herbals are sharper, brighter scents that smell fresh, lively and feel crisp.
