What is a flower essence?

A flower (leaf, mineral, animal, or environmental even!) essence is the vibrational energy of a plant (or whatever) imprinted into water with added alcohol for preservation. A dosage essence is a further dilution of the mother essence, working on a deep cellular level. They are often recommended for emotional work since the essence may help get into root issues. I also believe the environment of what is happening around the essence making can have an effect on the essence itself.
