title: [Herbal preparations have both effects and side effects. Widespread usage dictates knowledge among physicians].
abstract: The article gives a clinically oriented overview of the efficacy and safety of Ginkgo biloba, St. John's wort, ginseng, Echinacea, saw palmetto and kava based on American experiences. Clinical data support the efficacy for some of these drugs. None of them is free of adverse effects. Generally speaking, trials of herbal medicinal products have been too few, too small and too short. The lack of long-term studies is especially unfortunate since many of the drugs are used for a long time. The difference between American and Swedish legislation on herbal medicine products is described.
