Dong Quai Root Powder Extract 1% Lingustilide

Dong quai may raise the risk of bleeding, especially if you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin. Uterine stimulant and relaxant activity have been reported with A. sinensis, while a related species, Angelica archangelica L., was a reported abortifacient and affected the menstrual cycle.

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 (COA) are available for all our herbs.
