Using Flower Essences with Essential Oils: The basic difference is that essential oils are derived from the actual plant material, i.e., flowers, leaves, seeds, roots and bark by distillation or with citrus oils by cold expression method. These methods are used to create the essential oil found in colored bottles used in different aromatherapy applications. Flower Essences, on the other hand, are prepared by infusing the energy of the actual plant material into pure spring water preserved with brandy or an organic vegetable glycerin via the action of sun or moon light. The flower essences can be taken internally, either under the tongue or in water. They can also be applied topically or mixed with a lotion, as in the Bach 'Rescue' cream. Another difference between flower essences and essential oils is that flower essences do not posses the actual scent of the plant.
