Chamomile – most of us associate this daisy-looking ingredient with tea, but it’s available in essential oil form too. Chamomile oil comes from the flowers of the chamomile plant, which actually happens to be related to daisies (hence the visual similarities) and is native South and West Europe and North America.

Chamomile plants are available in two different varieties. There’s the Roman Chamomile plant (which is also known as English Chamomile)2 and the German chamomile plant. Both plants look largely the same, but it actually happens to be the German variation that contains more of the active ingredients, azulene and chamazulene,3 which are responsible for giving chamomile oil a blue tinge.4
