Flower Essences are the energetic imprints of flowers or plants that are stored in water and preserved by alcohol. They have been found to be of great benefit in the defusion of emotional stress. The most well-known flower essences are those of Dr. Edward Bach, the Bach Flowers, though many other sets ofessences now exist. Flower Essences are used in the One Brain program (in Advanced One Brain) and in Applied Physiology (in the Attitude with Essence module).
