Bisherige analytische Untersuchungen und die goetheanistisch-morphologische Gliederung der Gattung Equisetum werden erweitert durch Untersuchungen der wässrigen Auszüge von fünf einheimischen Schachtelhalmarten. Geschmacksuntersuchungen und Steigbilder der verschiedenen Pflanzenorgane im Jahreslauf vermitteln einen Einblick in die unterschiedlichen Lebensprozesse der einzelnen Arten. Winter- und Sumpfschachtelhalm (E. hyemale und E. palustre), die morphologisch vegetative und generative Prozesse verbinden, weisen in den Auszügen gemischte Geschmäcker auf und zeigen meistens gemischte Bildtypen im Steigbild. Wald- und Riesenschachtelhalm (E. silvaticum und E. telmateia) lösen morphologisch die generativen Prozesse als abweichende «fertile Triebe» aus dem Vegetativen heraus, physiologisch tritt das Krautige als Einzelgeschmack auf. In den Steigbildern erscheint über einen längeren Zeitraum und bei unterschiedlichen Organen ein einziger Bildtyp, beim Waldschachtelhalm der Aufstrebende Typ, beim Riesenschachtelhalm der Ablagerungstyp. Die Sonderstellung der Heilpflanze Ackerschachtelhalm (E. arvense) wird durch die Untersuchungen bestätigt. Geschmacksnuancen sind sowohl stärker vereinseitigt als auch mehr zusammengefasst. In seinen Steigbildern überwiegt der Quelltyp, durch den sich das jugendlich-vitale «schaffende Substanzbilden» äußert.
N1 -Previous analytical investigations and a Goethean-morphological classification of the genus Equisetum are here extended by studies of aqueous extracts of five native horsetail species. Taste tests and rising pictures (capillary dynamolysis) of its various organs in the course of the year provide insight into the contrasting life processes of the different species. Extracts of rough and marsh horsetails (E. hyemale and E. palustre), both of which combine morphologically vegetative and generative processes, always have mixed tastes and usually show mixed rising picture types. Morphologically, wood and great horsetails (E. silvaticum and E. telmateia) produce their generative processes as ‘fertile shoots’ diverging from the vegetative; physiologically a single, leafy taste occurs. Over a longer period and with samples of various organs, a single rising picture type appears: striving-upwards type with wood horsetail; depositing type with great horsetail. The special position of the common horsetail (E. arvense) that is used medicinally is confirmed by these investigations. Extracts sometimes present only one taste and sometimes a greater assortment of tastes mixed together. Its rising pictures are predominantly of the swelling type through which a youthful-vital ‘creative formation of substance’ is expressed.
