Hydrosols

Hydrosols, sometimes called hydrolates or floral waters, are natural byproducts of producing essential oils. During distillation, fresh plants and blossoms are combined with spring water. The water is heated, rises as steam, and passes through the plant material. The steam gathers the essential oil and other volatile compounds present. The essential oil that floats on the surface is removed, leaving the hydrosol, which contains a small amount of essential oil and other water soluble constituents from the plant.

Hydrosols do not smell exactly like the plants they come from, since they capture only the water soluble fraction of the plant. Their aroma can be described as earthy, though not unpleasant. Some hydrosols are virtually scent free, while others may carry a slightly musty note.

Because hydrosols are essentially water, they can be used in many settings, and in some cases they may even be consumed.

All of this should be considered carefully. Seek advice from knowledgeable professionals before any self directed use of these or any other ingredients.
