Rudolf Steiner was a consultant to Dr. Ita Wegman at the Clinical-Therapeutic Institute (Klinisch-Therapeutisches Institut) in Arlesheim. The therapeutic part of these consultations are documented in Rudolf Steiner’s Heilmittelangaben. It is quite informative to go through this collection and study Rudolf Steiner’s choice of potencies. Most frequently he recommended low potencies D3 [323], D6 [549], especially the latter. Medium potencies D10 [154] and D15 [155] are next, then higher concentrations, especially 5% [170]. Rarely did he prescribe beyond D30: Belladonna D60 and Succus citri D200 for psychiatric cases, Aesculus D50-D100 for dental cavities, Belladonna D30-D60 for epilepsy, Aesculus D50-D100 for Lupus….
