Roman chamomile essential oil is produced from Anthemis nobilis (Chamaemelum nobile) of the family species Asteraceae, formerly placed in the Compositae family. It is also known as English chamomile, sweet chamomile and garden chamomile.
German chamomile essential oil is extracted from Matricaria chamomilla (M. recutica) of the same family and is also known by the names of blue chamomile, Hungarian chamomile and single chamomile.
Both Roman and German chamomile have excellent calming properties, but Roman chamomile is more effective for irritation, impatience and feeling disagreeable, and has great value in treating PMS and other menstrual and menopausal problems, while German chamomile is superbly effective on the skin, not only to sooth and calm, but to heal and for tissue regeneration.
The Roman chamomile essential oil has a sweet, apple-like fragrance and is very light clear
blue in color with a watery viscosity, while the German chamomile oil has a sweet, straw-like
fragrance, is dark blue in color and its viscosity is medium.
Both types of chamomile oil are considered non-toxic and non-irritant, yet since they do have
emmenagogue properties when used in high concentrations, they should be avoided during pregnancy.
