A Darker Shade of Green: Medical Botany, Homeopathy, and Cultural Politics in Interwar Germany
Bibliographic record
Abstract
In 1941 a proposal was made to Nazi SS Reichsführer, Heinrich Himmler, that extracts of a South American plant, Dieffenbachia seguine, might be used for the mass sterilization of racially undesirable war prisoners. The proposal was based on published animal fertility research conducted by Dr Gerhard Madaus, co-founder of a firm that produced and marketed natural medicinals. His fertility experiments were part of a broader series aimed at evaluating the scientific validity of ethnobotanical folk-knowledge. This article traces the historical background to the Madaus research: first, the role of homeopathy in the introduction of Dieffenbachias to western medicine; secondly, the social context of German 'alternative' medicine in the interwar period; and finally, the role of Madaus himself, whose homeopathically-oriented research on botanical medicinals inadvertently initiated the chain of events described here.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
