“…In fact, plantbased experiments appear suitable for basic experimentation, making it possible to overcome some of the disadvantages of clinical trials, such as placebo effects and ethical problems. Moreover, botanical bioassays rely on a very cheap and almost inexhaustible source of biological material, and they need a short time to carry out each experiment and collect a large sample of data, essential for statistical analysis (Betti et al 2008Majewsky et al 2009). …”

This study concerns the biological effects and physico-chemical variations of extremely diluted solutions (EDS) as a function of aging-time. The biological efficacy of As 2 O 3 at the 45th decimal dilution/succussion (As 45×) was tested in a wheat germination model. Ten trials were carried out from 0 to 12 months after treatment preparation, using wheat seeds (Triticum aestivum L.) of the Pandas variety. Seeds were pre-treated by poisoning with 0.1% As 2 O 3 solution to reduce germination, to allow a better evaluation of treatment effects. The outcome variable was the number of non-germinated seeds after 96 h. The As 45× treatment aged for less than three months did not show a significant effect on wheat germination, whereas when aged for longer (3-12 months) the effect became significant. Concerning the physico-chemical characteristics, specific conductivity of As 45× aged from 0 to 12 months was measured, using nine samples for each date. The results showed a clear increasing time trend of specific conductivity, more evident when considering the last three measurements, which correspond to more than six months of aging. The physico-chemical behavior of EDS strongly supports the significant biological effects observed in a wheat model.

“…14 Since a 'Materia Medica' for plants e a compilation of symptoms which plants show after poisoning with a given substance e does not currently exist, ways to approximate classical homeopathy may be the use of phenomenological or biochemical symptoms on basis of the simile principle. 15 For this purpose homeopathic rules were applied and copied to the plant model. One of the authors described symptoms (KT) while another author experienced in classical homeopathy (MF) collected the symptoms and performed repertorisation (McRepertory Version 8, Synergy Homeopathic, Novato, CA, USA) extrapolating plant symptoms analogous to human symptoms ( Figure 1).…”

Under 'in situ' randomization/unblinding the odds of a seed not to germinate is 40% lower if treated with sulphur compared to placebo (p=0.004). In contrast, these odds are practically equal in the 'central' meta-group (OR=1.01, p=0.954). Under 'in situ' randomization/unblinding the odds of a seed to germinate with a length ≥1mm is practically equal if treated with sulphur or with placebo (OR=0.96, p=0.717). In contrast, these odds are 21% higher under sulphur compared to placebo in the 'central' meta-group (OR=1.21, p=0.062). In summary, we found a sulphur effect that is significantly different between 'in situ' and 'central' randomization/unblinding relating to all three stages of germination.

“…Generally, plants are able to react to potentized substances [2,3,4,5]. This capability of plants to react to homeopathy has mostly been proven by using healthy plants, but the observed differences to untreated plants were generally small.…”

“…The reaction of diseased plants to homeopathic treatment should theoretically be more pronounced. However, only limited scientific data on the effects of homeopathic preparations on diseased plants are known [2,3,4,5,6,7,8,9] and some of these assessments lack statistical evidence. Therefore, scientifically sound model systems have to be developed in order to assess the potential of homeopathic treatments for plant pests and diseases.…”

A laboratory model system with the rosy apple aphid (Dysaphis plantaginea Pass.) on apple seedlings was developed to study the effects of homeopathic preparations on this apple pest. The assessment included the substance Lycopodium clavatum and a nosode of the rosy apple aphid. Each preparation was applied on the substrate surface as aqueous solution of granules (6c, 15c, or 30c). Controls were aqueous solutions of placebo granules or pure water. In eight independent, randomized, and blinded experiments under standardized conditions in growth chambers, the development of aphids on treated and untreated apple seedlings was observed over 17 days, each. Six experiments were determined to assess the effects of a strict therapeutic treatment; two experiments were designed to determine the effects of a combined preventative and therapeutic treatment. After application of the preparations, the number of juvenile offspring and the damage on apple seedlings were assessed after 7 and 17 days, respectively. In addition, after 17 days, the seedling weight was measured. In the final evaluation of the six strictly therapeutic trials after 17 days, the number of juvenile offspring was reduced after application of L. clavatum 15c (-17%, p = 0.002) and nosode 6c (-14%, p = 0.02) compared to the pure water control. No significant effects were observed for leaf damage or fresh weight for any application. In the two experiments with combined preventative and therapeutic treatment, no significant effects were observed in any measured parameter. Homeopathic remedies may be effective in plant-pest systems. The magnitude of observed effects seems to be larger than in models with healthy plants, which renders plant-pest systems promising candidates for homeopathic basic research. For successful application in agriculture, however, the effect is not yet sufficient. This calls for further optimization concerning homeopathic remedy selection, potency level, dosage, and application routes.
