The Colored Light Elixirs are in 1/2 oz. bottles with a solution of water, brandy, vegetable glycerin and salt. Made by infusing colors into water using sunlight, they are all natural; there are no colorants in the bottles, just clear solution and transparent colored labels.
You can learn more about each color, including their internal use and application to specific skin zones in the Flora Corona Colored Light Elixir Repertory. For instance- adding a drop of Green Colored Light Elixir to warm water and applying over the heart area is soothing.
Each color has its complimentary color in light.
