The invention relates to a plant extract combination of ginkgo and ginseng which is effective especially in a (synergistic) over-additive manner and optionally comprises whitethorn extract. Ginseng is used in the form of an ethanol/ethanol/water extract while ginkgo is used in the form of an acetone/acetone-water extract, for example, and the active extracts are prepared at specific quantitative ratios, particularly <1.1:1, thus unexpectedly boosting the prevention or also the treatment of a decline in the mental capacity related to age or also other disorders. This results from an over-additive tandem effect by protecting neural cells and improving blood circulation while increasing energy supply and activating cerebral metabolism, not only in the cognitive-therapeutic field, an effect being obtained against harmful oxidative influences caused especially by decomposition products of effective substances, whereby in particular antioxidative protection extends in a complementary manner to several cell compartments.
Compartment-specifically effective combination of ginkgo biloba and ginseng extracts, wherein ginkgo is present in the form of an acetone or acetone/water extract, and ginseng is present as an ethanol or ethanol/water extract, and the (weight) ratio of gingko extract to ginseng extract amounts to 1.4:1 to 0.9:1.
Use of a combination of ginkgo biloba extract, extractant acetone or acetone/water, and ginseng root extract, extractant ethanol or ethanol/water, for the production of a remedy for preventive and/or therapeutic compartment-specific tandem protection in cases of mental performance reductions or problems, as a phytopharmaceutical or nutritional supplement.
