Also known as Hungarian, or Blue Chamomile, this variety of chamomile yields an essential oil that is deep blue due to its high chamazulene content (2-5%). The essential oil also contains a high percentage of alcohols such as bisabolol. Chamazulene is only found in the essential oils of both Roman and German chamomile and is created during the distillation process from another compound called matricin. This compound causes the essential oil of German chamomile in particular to go bright blue. Roman chamomile essential oils is often distilled in a way that prevents the formation of chamazulene as the industry prefers this oil to be a pale straw colour. Chamazulene is credited with providing the anti-inflammatory properties of both chamomiles.
