When flowers are gathered at the height of their power and beauty and added to water and allowed to permeate the water in the light of day, their essential energetic imprint permeates the water and can then be preserved with a pinch of alcohol such as brandy.  Flower essences work at a subtle level and appear to affect us where we are challenged and blocked emotionally and energetically.  Often flower essences catalyze shifts in mood, consciousness and insight.
