Flower Essences. Flower essences (which can also be extended to include gem elixers and other vibrational essences) are made from soaking a specific type of flower in water, often under certain types of conditions (such as full moon, sunlight, etc.) The water that is extracted from the process is said to hold the vibrational quality of the flower (or crystal, etc.). Thus, a company that sells California essences is providing flower essences made from native California flowers (most likely). You can also get Alaskan essences, South African essences, etc. Each flower provides a different type of healing vibration. So which ones you get will be determined on what you need to work on. For example, if you are suffering from heartbreak you might choose a flower essence that opens up the heart and heals old wounds. The specific brand does not matter as much as the *type* of essence you choose.
