HERBAL EXTRACT
INTRODUCTION:
Herbal extract is a liquid solution of herbs and
alcohol. The dried or fresh herbs are combined
with alcohol, then the solid matter is removed
leaving only the oils of the herbs mixed with
the alcohol. This process is called extraction,
hence the name, herbal extract. For example an
extract made from peppermint and alcohol would
be called "peppermint extract."
Most commercially sold extracts have a herb to
alcohol ratio printed on the label. When dry
herbs were used to make the extract the ratio is
commonly 1 part dried plant to 4 parts liquid,
(alcohol and water). When fresh herbs are used
the most common ratio is 1:1. This does not
indicate the amount of that herb in the bottle,
rather the ratio used in making the extract.
Example: Dry herb strength: 1:4 means that the
mixture used to produce the extract was 4 parts
liquid, (alcohol and water) and one part dried
plant. This is not the same as an ingredients
list which is also present on most commercial
extracts.
Herbal extracts are sold as dietary supplements
and alternative medicine and commonly used for
flavoring in baking and other cooking much like
vanilla extract.
