Hydrosols, also know
as hydrolats, floral waters, distillates and plant waters, are an
aqueous biproduct of the distillation process. There are many therapeutic
benefits found in hydrosols because they hold the water soluble properties
of the plant distilled, often including small quantities of water
soluble essential oil. They are not just waters but are imbued with
the aroma and flavor of the distilled material.
Hydrosols are the condensate water co-produced during the steam or
hydro-distillation of plant material for aromatherapeutic purposes.
Usually the distillation is undertaken to obtain the essential oils
contained in the plant material, but occasionally the distillation
is undertaken specifically to produce the plant water that results.
