Chamomile’s main volatile oil constituent Matricin is converted to chamazulene by steam distillation and gives Matricaria oil a remarkable blue colour, the deepness of which varies with the amount of azulene present.
The flowers should be processed soon after harvesting due to the volatile oils decreasing on drying. They can be preserved by freezing until ready for processing.
