Chemical Properties

Blue chamomile oil (German chamomile oil) is obtained by steam distillation of the flowers and stalks of Chamomilla recutita (L.) Rauschert (Matricaria recutita. L., Matricaria chamomilla L., Asteraceae). For oil production, chamomile is grown mainly in Eastern Europe (Hungary, Bulgaria) and Egypt. Few tons are produced annually. It is a deep blue or bluish-green liquid that turns green and, finally, brown when exposed to light and air. The oil has a strong, characteristic odor and a bitter, aromatic taste. Chamazulene is responsible for its blue color. Chamazulene and ()-α-bisabolol contribute to the anti-inflammatory properties of blue chamomile oil.
