Guest guest Posted June 16, 2005 Report Share Posted June 16, 2005 Alon, Eric, Bob, et al, The following is factual information concerning standardized extracts. This is mainly for Europe, however, Japan and Taiwan are generally held to a higher standard, though China is unlikely to be held to any standard. All of the below and not all extracts have markers added to bring things up; actually, most do not as it is semi-illegal to do so. Most " standardized " extracts are made by adjusting the amount of crude material used in making the extract to achieve the desired amount of " marker " . If a manufacturer can get 0.3% hypericin from using high quality material they can use less; if they need more they add more crude material. However, in the case of meeting pharmacopoeial standards, these often specify how little or how much crude material is needed to achieve the desired level of marker so that a manufacturer cannot use a ton of lousy quality raw material to make an extract that passes. Also, if one were to follow WHO guidelines, added chemicals (markers) could not be added to a product to meet a specific standard. The addition of such markers may also be illegal in Europe, though it surely has happened in both European and American markets.
