Essences are energised waters that help with healing, usually the emotional body. (Homeopathy helps heal the physical body and relates more to the etheric body.) They are made by using sacred water from various sites such as the waters of Chalice Well in Glastonbury, and energising them further by putting flowers, herbs or plants into the water and solarising it , thus creating a gentle healing vibration that helps unlock and release those negative energies that no longer serve us. Sometimes people harness the energy of the moon or other spiritual energies and the subtle vibrations are locked in to the water. To further explore this, read my articles under this heading which give a fuller explanation.
