Astragalus Root Powdered Extract 10:1, 25 kg (55 lbs)

All orders from this warehouse come with a Packing List and Certificate of Analysis.

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 say.

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.
