In nutricines based on plants the totality of components is usually respected. By analogy with the whole food-concentrates, a synergy of different compounds may be expected again. If the powder of the dried plant is used in the nutricine, then this is the actual whole food concentrate. Usually however, extracts or infusions of plants or plant parts (root, flower,leaf, herb, or just the completely above ground parts) are produced.
In the making of infusions and their subsequent processing the standardization technique may be applied. From year to year and from growth period to growth period, a plant may contain a different content of active substances. This makes sense since environmental factors such as the number of sun hours, the presence of natural predators, night temperature and so on, determine the number of active plant substances. Standardization assures that each batch number of nutricines always
contains the same amount of active substances.
The plants of the high quality Nutrisan supplements usually contain the proper standardizations, needed to ensure the efficiency of a nutricine! The standardizing is noted on the packaging of high quality nutricines. The plant is listed with a percentage of an at first sight complex material that refers to an active ingredient (e.g., Siberian ginseng, standardized to 1% eleutherosides).
