Context: This research aimed at verifying the efficacy of homeopathic treatments by plant-based bioassays, which may be suitable for basic research, because they lack placebo effects and provide large datasets for statistical analyses. Objective: To evaluate the effects of homeopathic treatments of arsenic trioxide (As2O3) on tobacco plants subjected to tobacco mosaic virus (TMV) inoculation as biotic stress. Design: Blind, randomized experiment using tobacco leaf disks. Materials and methods: Tobacco plants (Nicotiana tabacum L. cultivar Samsun) carrying the TMV resistance gene N. TMV inoculated leaf disks were floated for 3 days in the following: • Distilled water (control) • H2O 5 and 45 decimal and centesimal potencies • As2O3 5 and 45 decimal and centesimal potencies The main outcome measures is the number of hypersensitive lesions observed in a leaf disk. Results: Homeopathic treatments of arsenic induce two effects on the plant: (i) increased resistance to TMV; (ii) decrease variability between experiments (system variability). Conclusions: In this experimental model two actions of homeopathic treatment were detected: decrease in system variability and enhancement of the natural tendency of the system towards an ‘equilibrium point’. |
