Rae potentiser uses magnetic fields to induce potency energy patterns in moistened sac lac, water, etc. It is well know that such compounds are 'different' from nartural organic chemicals - eg vitamins and hormones, diamonds, etc. They also have different crystalline structures and water of crystallisation. Vitamin C from blackcurrants compared with oranges, lemons, etc. Plant growth is subtly influenced by minerals and water, eg plant roots change growth course before they bend around a stone in the soil.
Plant roots display very sensitive growth patterns to a range of chemical and gravitational stimuli.
Some fascinating research was done on this by Kolisko and Fyffe in 60's. Differences in crystalline structures due to subtle sub-magnetic forces in the lattice holding the molecules in place. Contaminant molecules can radically alter crystallisation patterns. Jack Temple freaks go even further than Steiner and claim that different individual crystals or places have different healing powers. Different places have different geo-magnetic characteristics.
