Abstract: Certain scientific as well as other publications may direct the attention of physicians and laypeople more than usual to certain diseases and those remedies being (or just seeming) suitable for them.Especially with phytopharmaceutics, mainly used in selfmedication, this fact leads not infrequently to a rush for certain plant drugs and preparations thereof (Modedrogen). In the first time of their use they often will be overestimated, later possibly underestimated.Whether these phytopharmaceutics are worth their money or not can easily be demonstrated,- for instance with the so-called adaptogenes like Ginseng or Eleutherococc or with immunostimulants like Echinacea, though classical medicine is still very critical about these indications or drugs respectively. The same is true for preparations from garlic, Ginkgo and Urtica which are often very different looked upon by pharmacologists on the one hand and general practitioners on the other hand.This survey will show the qualifications needed for those plant drugs and preparations thereof to be accepted remedies in the realm of classical medicine. Basic conditions, they have to comply with, are pharmaceutical and therapeutical quality including standardization of phytopharmaceutics in relation to content of active principles and evidence of efficacy and safety. Both are valid only for the drugs and preparations tested and not for other preparations of the same drug. In this context it is also indispensable to prevent misuse through arbitrary and adlibitum application.
