4:1 is a reference to the strength of the evaporated decoction (alcohol
and/or water) from which the concentrated herb powder is made: 4 parts
of botanical to 1 part native extract, as the certificates of analysis
A standardized herbal extract is an herb extract that has one or more
components present in a specific, guaranteed amount, usually expressed
as a percentage. The intention behind the standardization of herbs is
to guarantee that the consumer is getting a product in which the
chemistry is consistent from batch to batch. Standardized extracts are
usually in a base of the whole herb powder.
In most cases, ratio 4:1, 5:1, 10:1 herbal extracts are not as potent as
standardized % herbal extracts, although, since concentrated, ratio
extracts are usually more potent than whole herb.
Our herbal extracts are produced in GMP compliant facilities. Certificates of analysis are available for all our herbs.
