The scope of this project is the investigation of the possible occurrence of force-like effects of potentized preparations. Based on earlier work [1, 2] we have chosen two preclinical models: a droplet evaporation method applied on wheat seeds and a bioassay with cress stressed with colchicine. In both methods we investigate if potentized and not potentized substances exhibit force-like effects.
We study two types of potentization procedures. First we study classical homeopathic potentization (Natrium muriaticum 30cH) and compare it with unpotentized NaCl 0.9%. Second, we study anthroposophic potentization (Iscador, mistletoe (Viscum album L.) extracts treated with a special mechanized pharmaceutical process) and compare it with unpotentized mistletoe extract (not mechanically treated).
Droplet evaporation method is performed as described in detail elsewhere [1]. In short: wheat seeds were placed in the inner space of bilayer recipients, whereas, in the outer space (i) the unpotentized substance, (ii) the potentized substance, or (iii) a water control is placed. After one week wheat seeds are removed from the recipients and placed in water for 1h. Droplets of the obtained leakage were evaporated on glass-slides in controlled conditions. The droplet residues are photographed in magnification 100x and analyzed for fractal dimension.
Cress growth test is performed as described in detail elsewhere [2]. For the study of force-like effects, ampoules of the above mentioned substances and ampoules of water for injection are placed for 2 days in recipients filled with purified water. Subsequently 20 µg/ml colchicine were added. The so prepared water is used to grow selected cress seeds in bags for 4 days. The plants grow in darkness under controlled conditions and show a morphological malformation due to the colchicine. The length of the root and shoot at each plant is measured and the root/shoot ratio is calculated, to determine if there is any difference between the treatments.
