All the oils of Chamomile have the same calming and lenitive property. They act at every level: physical, emotional and spiritual.
The deep blue colour of the German Chamomile, (variety Matricaria) harmonize well with the Chakra of the Throat, for which it has the same strengthening and lenitive effect that can be reinforced by association with blue crystals, like the Tourmaline. Use it when you have necessity to communicate, to say the truth without hatred or bitterness.
The English Chamomile (Anthemis nobilis) is paler, has a lighter blue colour, and also this harmonizes with the Chakra of the throat, but on the higher tone. This oil can help the persons to express their higher spiritual truth, and can also help the healers.
Use it with pale blue precious stones (Blue Agate or Aqua marine , for instance) in Cristaltherapy. The blue is generally a calming colour, and Chamomile can be used in order to fight the agitation or the hyperactivity of any chakra.
