Herbal distillate

VIEWS: 32 PAGES: 2

									Herbal distillate
Herbal distillates are aqueous solutions or colloidal suspensions (hydrosol)
of essential oils usually obtained by steam distillation from aromatic plants. These
herbal distillates have uses as flavorings, medicine and in skin care. Herbal distillates
go by many other names including floral water, hydrosol, hydrolate, herbal water and
essential water.
Herbal distillates are produced in the same manner as essen tial oils. However, the
essential oil will float to the top of the distillate where it is removed, leaving behind
the watery distillate. For this reason perhaps the term essential water is more
descript. In the past, these essential waters were considered a byproduct of
distillation, but now are considered an important co-product. Much of the process of
making and using herbal distillates was documented in Grace Firth's 1983 book
titled Secrets of the Still.[1]
The science of distillation is based on the fact that different substances vaporize at
different temperature. Unlike other extraction techniques based on solubility of a
compound in either water or oil, distillation will separate components regardless of
their solubility. The distillate will contain compounds that vaporize at or below the
temperature that water boils. The actual chemical components of distillates have not
yet been fully identified, but distillate will contain essential oil compounds as well as
organic acids. Compounds with a higher vaporization point will remain behind and
will include many of the water soluble plant pigments and flavonoids.
Herbal waters contain diluted essential oils. Besides aromatic chemicals, these
distillates also contain many of the plant acids than pure essential oils making them
skin friendly [citation nee ded]. Cosmetics and toiletries makers are finding many uses for
herbal distillates. A pH between 5-6 makes them suitable for use as facial
toners[citation nee ded]. They can be used alone as room sprays. Distillates are also used as
flavorings and curables.
Because hydrosols are produced at high tem peratures and are somewhat acidic, they
tend to inhibit bacterial growth. They are not however sterile. They are a fresh
product, like milk, and should be kept refrigerated. [2] Small-scale producers of
hydrosols must be particularly aware of, and take steps to
prevent bacterialcontamination.[3]
