OBJECTIVES A bioassay with arsenic-stressed duckweed (Lemna gibba L.) was developed to study potentially regulative effects of homeopathic preparations. We compared potentized substances (nine different potency levels between 17 x and 33 x ) with two controls (unsuccussed and succussed water) regarding their influence on number- and area-related growth rate and color of fronds (leaves). Screening included 11 potentized substances: Arsenicum album, gibberellic acid, nosode, arsenic(V… Expand
Effects of Homeopathic Arsenicum Album, Nosode, and Gibberellic Acid Preparations on the Growth Rate of Arsenic-Impaired Duckweed (Lemna gibba L.)
TLDR
The test system with L. gibba impaired by arsenic(V) was stable and reliable and will provide a valuable tool for future experiments that aim at revealing the mode of action of homeopathic preparations. Expand
Effects of Homeopathic Preparations of Mercurius corrosivus on the Growth Rate of Severely Mercury-Stressed Duckweed Lemna gibba L.
TLDR
The present test system with Lemna gibba L. that was severely stressed by mercury yielded evidence for specific effects of Merc-c. Expand
Effects of Homeopathic Preparations of Mercurius corrosivus on the Growth Rate of Moderately Mercury-Stressed Duckweed Lemna gibba L
TLDR
Moderately mercury-stressed Lemna gibba L. yielded evidence of growth-enhancing specific effects of Merc-c. Expand
Comparative study of two bioassays with weakened duckweed and yeast treated with homeopathic preparations
In homeopathic basic research, the question as to the most adequate test systems and apt methodology is still open. This investigation examined the hypothesis that more complex organisms showExpand
Investigation of Arsenic-Stressed Yeast (Saccharomyces cerevisiae) as a Bioassay in Homeopathic Basic Research
TLDR
No significant effects were found for any outcome parameter or any homeopathic treatment in this study with yeast and some specific properties of this experimental setup with yeast must be responsible for the lacking response. Expand
Use of homeopathic preparations in experimental studies with abiotically stressed plants.
TLDR
Abiotically stressed plant models seem to be a useful approach to investigate homeopathic basic research questions, but more experimentation and especially more independent replication trials are needed. Expand
Nanoparticle Characterization of Traditional Homeopathically-Manufactured Gelsemium sempervirens Medicines and Placebo Controls
TLDR
The data suggest that traditional homeopathic methods involving succussions release not only the previously-shown silica from glassware walls, but also Quercus suber materials from natural cork stoppers to stabilize NPs in solution. Expand
Effects of homeopathic high dilutions on plants: literature review
TLDR
Despite the substandard methodological quality of most experiments, studies with systematic use of negative controls and reproducibility demonstrated significant indisputable effects of homeopathic HD on plants. Expand
17 – A comparison of commonly used and commercially available bioassays for aquatic ecosystems
TLDR
This chapter focuses on the comparison of the most common bioassays used in aquatic ecotoxicology in terms of their sensitivity, cost, and response time. Expand
Ultra high diluted arsenic reduces spore germination of Alternaria brassicicola and dark leaf spot in cauliflower
TLDR
Dado that o elevado nivel de diluicao impede qualquer toxicidade ou acumulo no ambiente, o uso of UHDs poderia ser considerado uma abordagem potencial e confiavel para a agricultura sustentavel. Expand

Duckweed (Lemna gibba L.) as a test organism for homeopathic potencies.
TLDR
A bioassay with duckweed (Lemna gibba L.) was used to study the effects of homeopathic potencies on the plant's growth rate and appears to be a promising new model system to investigate effects of potentized substances. Expand
Effects of potentised substances on growth rate of the water plant Lemna gibba L.
TLDR
Lemna gibba may be considered as a suitable test organism for further studies on the efficacy of homeopathic potencies, as evidence accumulates, that adjacent potency levels may strongly differ in their biological activity. Expand
The Effects of a 45x Potency of Arsenicum album on Wheat Seedling Growth – a Reproduction Trial
TLDR
The result of this replication trial is a reversal of the original study, since Arsenicum album 45x inhibited wheat shoot growth instead of enhancing it, Nevertheless, high homeopathic potencies may induce statistically significant effects in biological systems. Expand
Arsenic removal from waters by bioremediation with the aquatic plants Water Hyacinth (Eichhornia crassipes) and Lesser Duckweed (Lemna minor).
TLDR
The Water Hyacinth had a removal rate of 600mg As/had and a removal recovery of 18%, under the conditions of the assay and this specie represents a reliable alternative for arsenic bioremediation in waters. Expand
The Efficacy of Ultramolecular Aqueous Dilutions on a Wheat Germination Model as a Function of Heat and Aging-Time
TLDR
The main conclusion suggested by this experiment is that the efficacy of As2O3 45× on wheat germination may be influenced by heating degree and seems to have an increasing trend as a function of aging. Expand
Models with Plants, Microorganisms and Viruses for Basic Research in Homeopathy
TLDR
Research has been carried out into the applicability of homeopathic principles to crop growth and disease control (agrohomeopathy), but there is little firm evidence to support the reliability of the reported results, due to poor experimental methodology and inadequate statistical analysis. Expand
Use of homeopathic preparations in phytopathological models and in field trials: a critical review.
TLDR
The prospects for homeopathic treatments in agriculture are promising, but much more experimentation is needed, especially at a field level, and on potentisation techniques, effective potency levels and conditions for reproducibility. Expand
Isopathic treatment effects of Arsenicum album 45x on wheat seedling growth--further reproduction trials.
TLDR
Ultramolecular Ars-alb 45x led to statistically significant specific effects in arsenic poisoned wheat when investigated by two independent working groups, however effect size and effect direction differ, however. Expand
A Follow-Up Study on the Efficacy of the Homeopathic Remedy Arsenicum album in Volunteers Living in High Risk Arsenic Contaminated Areas
TLDR
Administration of Arsenicum album 200C considerably ameliorates symptoms of arsenic toxicity on a long-term basis, and can be recommended for interim use, particularly in high risk remote villages lacking modern medical and arsenic free drinking water facilities. Expand
Use of homeopathic preparations in experimental studies with healthy plants.
TLDR
Healthy plant models seem an useful approach to investigate basic research questions about the specificity of homeopathic preparations, especially in the sectors of potentisation techniques, effective potency levels and conditions for reproducibility. Expand
