A standardized extract is a product in which a specific concentration of a particular constituent or group of constituents is guaranteed. While all the original constituents may still be present, they are often not in the proportions found in the original herb. While this approach is attractive to the conventional medical model, it depends on the existence, extraction, and identification of a discrete single active constituent or group of constituents. The effect of this approach on the synergy reputed by herbalists to exist between components has yet to be clarified.[1]
