| Why standardisation? |
|
Standardisation ensures that the extract
always contains exactly the same amount of active substances - a basic requirement
for a constant effect of the finished product and for clinical studies.
The extraction method is a crucial factor for the composition of the extract.
In extracts produced by different extraction methods different compounds
may be present in varying concentrations. Thus, the pharmacological activity
of an extract mainly depends on the extraction method used.
When choosing a herbal supplement brand, remember that you are buying an
extract, not a plant. A common misperception is that all products containing
the same plant must be the same.
Consider, for example, the winemaking process. A wine produced by a company
on the east side of a hill might taste dramatically different from one produced
by another company on the west side of the same hill. The same potential
holds true for herbal medicinal products. Many variables can change according
to growing conditions, harvesting and manufacturing differences. In order
to control for these variables, Pharmaton standardises its extract and quality
process.
What can a consumer do to avoid the problems of inconsistent extracts? Simple.
Buy a brand such as Pharmaton®, which is manufactured using the
standardised ginseng extract G115®, prepared according to strict guidelines
to ensure exact standardisation. You can be assured that the product you
take is the same as the one tested in several clinical studies. Pharmaton® contains the most clinically tested ginseng extract in the world
and has proven safety and efficacy - do not accept substitutes!

| Process of standardization |
|
Sowing the seeds
The Panax ginseng C.A. Meyer seeds are planted in carefully prepared nursery beds that have been fertilised with shredded ginseng leaves. |
|
Careful cultivation
The Panax ginseng C.A. Meyer seeds are cultivated under the most suitable climatic, soil and light conditions and with the aid of natural fertilisers. |
|
Harvest and careful selection
The roots are harvested after 4 to 6 years of growth, in September or October, when they have developed the maximum concentration of active ingredients. Careful selection is done to screen out unsuitable roots. |
|
Test for contaminants
The roots undergo complete physical, chemical and microbiological analysis before they are released for extraction and standardisation. |
|
Extraction of the ginseng roots
The extraction process developed by Pharmaton is ideal for extracting all medicinally relevant components from the plant. The liquid extract is concentrated and sterilised (UHT treatment), then the dry native extract is prepared by spray-drying. It is carried out at low temperatures. Laboratory investigations are carried out to test for residual pesticides. The UHT method is used to completely eliminate pathogens. |

Standardisation of G115 extract
Standardization of the active substances using High Pressure Liquid Chromatography (HLPC) to obtain Standardized Ginseng Extract G115. This ensures a consistent ginsenoside content and exact concentration to achieve optimal effectiveness. Every batch of G115® ginseng extract has the same known and consistent level of the main active constituents. While many other ginseng products have been shown to vary greatly in ginsenosides content (and a few to have no ginsenosides at all), G115® always contains 4% ginsenosides. G115 is the first and only ginseng extract which has been extensively researched in humans. |
