Hydrosols are distilled from the entire plant material, unlike essential oils which are often obtained from select parts of the plant. Therefore, hydrosols may smell quite different and distinct when comparing them to the essential oil of the same plant.

Hydrosols are often used in creating body products, room sprays and linen mists. They are also popular for use in other herbal preparations. They are an excellent complement to essential oils because they are gentle enough to be used directly on the skin and can be used on children and pets.
