Since there are two unique varieties of chamomile, you’ll find their aromas also vary. German (Blue) chamomile, Matricaria recutita, has an herbaceous fragrance that is sweet, fruity, strong, and rich, while Roman chamomile, Anthemis nobilis / Chamaemelum nobile, smells like fresh apples.
Nervine essential oils strengthen the nervous system.
Clary Sage’s aroma varies, but it is most often described as earthy and warming. Some variations emanate fruit, floral, sweet, or bittersweet scents, while others are considered musky, herbaceous, or dry.
Marjoram has a spicy, herbal, slightly camphoraceous aroma.
