Are German and Roman Chamomile related?
German chamomile (Matricaria chamomilla) and Roman chamomile (Chamaemelum nobile) are different plants of the same family. As herbs, they are both considered kinds of chamomile with similar properties. As essential oils, they are also similar but differ in one significant respect. German chamomile oil has a blue in color that comes from a constituent called chamazulene, a potent anti-inflammatory which is produced during the distillation process. Roman chamomile has little or no chamazulene, and therefore lacks the blue color and anti-inflammatory properties.
