Zusammenfassung
Das Potenzial des Spargels als Heilpflanze könnte höher sein, als dies durch den gegenwärtigen Untersuchungsstand dokumentiert ist. Selbst die scheinbar unstrittige diuretische Wirkung des Spargels ist unzureichend wissenschaftlich belegt, und die phytotherapeutisch interessanten Inhaltsstoffe des Spargels sind kaum charakterisiert. Aktuelle Analysen der Inhaltsstoffe und ihrer Wirkungen liegen beinahe ausschließlich für nichteuropäische Asparagus-Arten vor. Untersuchungen an außereuropäischen Spargelarten haben interessante Heilwirkungen aufgezeigt, wobei eine diuretische Wirkung keine Rolle spielt. Unter den Inhaltsstoffen erscheinen die vorwiegend in den Wurzeln enthaltenen Saponine am interessantesten.
Summary
In spite of the high potential of asparagus as a medicinal plant, it has so far received very little research documentation. A case in point is its apparently controversial diuretic effect that has not attained sufficient scientific verification; also the most important phytotherapeutic components have hardly been characterised. Current analyses of the components and their effects are almost exclusively available for non-European asparagus species. Research on non-European species has shown interesting curative effects where diuretic effect did not play a role. Saponins, found mainly in the roots, seem to be the most important components of asparagus.
