These are energetic medicine tools used in crystal healing. The idea is very similar to Flower Essences. The energy of the crystal is transferred to the water, under both sun and moon,and so it takes on the healing properties of the crystal. These essences come in 1 Oz/30ml bottles with a pipette, generally you start with 7 drops per day and reduce as and when you feel you should. If you aren't sure which crystal essence you need, send us a message and our dedicated crystal healer will be happy to help you decide.
