Hydrosols are produced by water or steam distillation of the flower or herb, and contain most of the hydrophilic (water soluble) molecules from the plant or flower material that did not distil into the essential oil.

Hydrosols are also know as hydro late, distillate water or flower water.

Hydrosols contain all of the essence of the plant in every drop, just like essential oils but in a milder form; making them suitable for all manner of application where essential oils would be too strong.

Thus the hydrosol acts as a healing anti-inflammatory and mild, but therapeutic antiseptic. Bacteria do not live well in acid environments.
