Introduction:  In 2021, the area of CRAS (Centro de Reabilitação de Animais Selvagens - Wild Animal Rehabilitation Center), located in a state park in Campo Grande City, Mato Grosso do Sul, Brazil, was suffering from a tick infestation affecting wild animals that inhabit the area and humans that visited its trails. Following a formal technical-scientific cooperation agreement between IMASUL, an institute for the environment in Mato Grosso do Sul state, and SIGO Homeopatia, a formulated homeopathic complex ( Formula Parques Urbanos , FPU) was designed and prepared specifically to treat the animals. This environmental intervention used specially designed slow-release water biodegradable devices. Tracking the FPU signal in water was necessary to monitor and manage the intervention., Aims:  Our aims were (1) to evaluate, among six previously standardized solvatochromic dyes, which would serve as a marker for the homeopathic complex under study; and (2) to evaluate whether the chosen solvatochromic dye could map the propagation of the homeopathic complex activity throughout the stream system from water samples harvested at different locations over time., Method:  Water samples were harvested from each point at different times, filtered, frozen, and sent to the laboratory, where they were prepared at 1cH potency for analysis using 30% ethanol as the vehicle. Solvatochromic dyes were used to analyze the samples since they alter their absorbance when in contact with homeopathic potencies. Of the six dyes tested, Coumarin 7 was found to be the most suitable for tracking the FPU complex. A static and average unidirectional magnetic field of 2,400 Gauss (240 mT), generated by a neodymium magnet, was applied to the samples immediately before reading., Results:  There were significant differences in the delta absorbance of dyes when adding treated/potentized water samples, making it possible to map the propagation of the FPU signal throughout the park over time. The signals were identifiable at the same point 1 minute and 32 days after the insertion of the device into the water. These signals were also identifiable after 75 minutes and 8 days at a point far from the insertion place., Conclusion:  Coumarin 7 was the best marker for the homeopathic complex (FPU) used to treat the wild animals living in the park. The microplates/enzyme-linked immunosorbent assay reader method and the application of a magnetic field to samples were shown to be effective in tracing homeopathic signals by changes in dye absorbance ( p ≤ 0.02) in a real-life situation, with large volumes of water, involving many environmental variables, and over large distances., Competing Interests: The samples were made available for analysis by SIGO Homeopatia company in partnership with the governmental organization IMASUL (Instituto do Meio Ambiente do Mato Grosso do Sul). No other resource was given to the researchers., (Faculty of Homeopathy. This article is published by Thieme.)

Background: Whilst it is assumed that water plays a crucial role in homeopathy, it is unclear what specific functions water has in the generation, propagation and maintenance of homeopathic potencies. Solvatochromic dyes have demonstrated themselves to be reliable indicators of the presence of potencies and so are well placed to begin to address these questions., Objective: The aim of the current study was to ascertain whether pure water could be potentised. If pure water can be potentised, this would indicate that water plays a crucial role in the generation of homeopathic potencies. If it cannot be potentised, then this result points to water being an inert carrier and medium for the potentisation of substances placed in it., Methods: A specially designed potentiser capable of consistently and reliably producing homeopathic potencies to rigorous standards (Pinkus Potentiser) was used to run up potencies of "Water 10M" and Arsenicum 10M in two interchangeable stainless-steel vials. "Water 10M" and Arsenicum 10M, along with unsuccussed control water, were then tested against solutions of the solvatochromic dye phenol blue by following the absorbance of the dye at 658 nm. RESULTS ": Water 10M" gave results no different statistically from unsuccussed water ( p  > 0.05) with no change over the time course of the experiments, whereas Arsenicum 10M gave statistically different results ( p  < 0.001) with increasing divergence from both "Water 10M" and unsuccussed water over time. Similar results were obtained when the vials in which Arsenicum 10M and "Water 10M" were produced were exchanged, so that the vial in which Arsenicum 10M had been produced was then used to produce "Water 10M" and vice versa, indicating the results could not be explained by any anomalies in the production vials themselves., Conclusion: Results using the solvatochromic dye phenol blue to detect and measure homeopathic potencies indicate that bulk water itself does not potentise and that unsuccussed water and water that has been succussed are no different. This indicates that what is potentised during cycles of dilution and succussion are the substances placed in water and not the water itself. In turn, this indicates that water is simply a carrier for the homeopathic signal. Evidence from the practice of homeopathy supports this conclusion., Competing Interests: None declared.

Introduction:  Cyanobacteria are microorganisms found in many parts of the world and several genera, such as Raphidiopsis raciborskii , are producers of cyanotoxins. Homeopathic potencies have been found to modulate toxicity in different biological models, and the present study endeavors to discover whether this might also be the case with cyanobacteria., Objectives:  Our objective was to investigate the possible effects of homeopathic potencies on the resilience of Artemia franciscana (brine shrimp) embryos to saxitoxin (STX; cyanotoxin) and on controlling the growth of R. raciborskii in vitro ., Method:   A. franciscana cysts were cultivated in seawater in 96-well plates to evaluate the hatching rate and vitality, plus the gene expression of heat shock proteins (HSPs), after being challenged with R. raciborskii extract containing 2.5 µg/L of STX and treated with different homeopathic potencies. Untreated wells were used as controls ("base-line"). Potencies were chosen from a screening process based on seven selected homeopathic preparations according to the similitude of STX symptoms ( Sulphur , Zincum metallicum , Nitric acidum , Plumbum metallicum , Mercurius solubilis , Phosphoric acidum , Isotherapic from R. raciborskii extract; all at 6cH, 30cH and 200cH). Cultures of R. raciborskii maintained in an artificial seawater medium were equally treated with screened homeopathic potencies selected from the same list but specifically for their growth control as a function of time., Results:  A 15% lower rate of hatching of A. franciscana cysts was observed after treatment with Nitric acidum 6cH in comparison with baseline ( p  = 0.05). A complete toxicity reversal was seen after treatment with Isotherapic 200cH, with a 23-fold increase of Hsp 26 gene expression ( p  = 0.023) and a 24-fold increase of p26 gene expression ( p ≤ 0.001) in relation to baseline. Nitric acidum 200cH and Mercurius solubilis 30cH limited the exponential growth of cyanobacteria up to 95% and 85% respectively ( p ≤ 0.003) in relation to baseline. Succussed water presented only a transitory 50% inhibition effect., Conclusion:  Isotherapic 200cH improved A. franciscana bioresilience to STX; Nitric acidum 200cH and Mercurius solubilis 30cH showed the optimal performance on limiting R. raciborskii growth. The results point to the potential of homeopathic potencies to mitigate environmental problems related to water quality., Competing Interests: None declared., (Faculty of Homeopathy.

Introduction:  The control of cyanobacterial toxicity and growth by homeopathic potencies was described in Part 1 of this two-part report. Here, a parallel approach characterized the physico-chemical features of the potencies used and the liquid media treated with them, correlating these results with their respective biological effects., Objectives:  Our objective was to establish if physico-chemical parameters can track homeopathic potencies in seawater or artificial seawater medium (ASM)-1 and to discover whether these parameters correlate with previously described biological effects., Method:   Artemia franciscana (brine shrimp) cysts were cultivated in seawater challenged with Raphidiopsis raciborskii extract and treated with different homeopathic potencies chosen from a screening process. Cultures of R. raciborskii maintained in ASM-1 were also treated with previously screened homeopathic potencies, and their growth was monitored as a function of time. The physico-chemical properties of the treated media (seawater or ASM-1) were evaluated by their interaction with solvatochromic dyes and changes in pH, conductivity and temperature., Results:  Coumarin 7 was found to be a marker for Nitric acidum 6cH and Isotherapic ( R. raciborskii extract) 200cH in seawater (analysis of variance [ANOVA], p  = 0.0015). Nile red was found to be a marker for Nitric acidum 200cH and Mercurius solubilis 30cH in ASM-1 (ANOVA, p ≤ 0.001). An increase in pH of ASM-1 and endothermic effects were observed after these treatments (two-way ANOVA, p  = 0.0001). Seawater and ASM-1 to which potencies had been added were also subjected to a constant unidirectional 2,400 Gauss static magnetic field and found to have enhanced effects on the solvatochromic dyes tested., Conclusion:  Homeopathic potencies were specifically traceable in aqueous media using solvatochromic dyes, especially when the samples were subjected to a magnetic field. Results from monitoring other physical parameters, such as pH and temperature, were less specific in relation to potency tracking. However, potency-induced endothermic effects might provide valuable thermodynamic data relating to the nature of potencies., Competing Interests: None declared., (Faculty of Homeopathy.

Glyphosate is an herbicide widely used in agriculture but can present chronic toxicity in low concentrations. Artemia salina is a common bio-indicator of ecotoxicity; it was used herein as a model to evaluate the effect of highly diluted-succussed glyphosate (potentized glyphosate) in glyphosate-based herbicide (GBH) exposed living systems. Artemia salina cysts were kept in artificial seawater with 0.02% glyphosate (corresponding to 10% lethal concentration or LC10) under constant oxygenation, luminosity, and controlled temperature, to promote hatching in 48 h. Cysts were treated with 1% ( v / v ) potentized glyphosate in different dilution levels (Gly 6 cH, 30 cH, 200 cH) prepared the day before according to homeopathic techniques, using GBH from the same batch. Controls were unchallenged cysts, and cysts treated with succussed water or potentized vehicle. After 48 h, the number of born nauplii per 100 µL, nauplii vitality, and morphology were evaluated. The remaining seawater was used for physicochemical analyses using solvatochromic dyes. In a second set of experiments, Gly 6 cH treated cysts were observed under different degrees of salinity (50 to 100% seawater) and GBH concentrations (zero to LC 50); hatching and nauplii activity were recorded and analyzed using the ImageJ 1.52, plug-in Trackmate. The treatments were performed blind, and the codes were revealed after statistical analysis. Gly 6 cH increased nauplii vitality ( p = 0.01) and improved the healthy/defective nauplii ratio ( p = 0.005) but delayed hatching ( p = 0.02). Overall, these results suggest Gly 6cH treatment promotes the emergence of the more GBH-resistant phenotype in the nauplii population. Also, Gly 6cH delays hatching, another useful survival mechanism in the presence of stress. Hatching arrest was most marked in 80% seawater when exposed to glyphosate at LC10. Water samples treated with Gly 6 cH showed specific interactions with solvatochromic dyes, mainly Coumarin 7, such that it appears to be a potential physicochemical marker for Gly 6 cH. In short, Gly 6 cH treatment appears to protect the Artemia salina population exposed to GBH at low concentrations.

Background: Highly diluted and succussed solutions (homeopathic potencies) have been shown to interact with a wide range of solvatochromic dyes based on changes in their UV-visible spectra. Studies so far have involved free dyes in solution, but there is a pressing need to find ways to investigate the potency-dye interaction using isolated dye molecules to ask more searching physico-chemical questions regarding the fundamental nature of potencies., Aims and Methods: The aims of the present study have been to look for ways to covalently immobilize solvatochromic dyes onto transparent cellulose films and hence be in a position to investigate dye-potency interactions without the complication of dye-dye interactions, including dye aggregation, which can occur with free dyes in solution., Results: To date, a total of nine different dyes have been immobilized on cellulose films using epoxide activation of hydroxyl groups on the cellulose surface. Using this method, studies have begun looking at the time course of potency action on one of these immobilized dyes, Brooker's merocyanine. Results show that the interaction of Arsenicum 10M with this dye consists of three phases-an initial growth phase, a sustained plateau of interaction, and a final decline phase lasting several days., Conclusion: A method has been developed that successfully immobilizes solvatochromic dyes onto transparent cellulose film. These films can then be used in a spectrophotometer to study at a much more detailed level how potencies interact with dyes compared with using free dyes in solution. Results indicate that the information gained in this way provides new insights regarding the fundamental nature of potencies. Specifically, studies using immobilized Brooker's merocyanine with Arsenicum 10M reveal that the lifetime of the potency is much longer than expected and that its action consists of three distinct phases, suggesting a resonant interaction with the dye. How resonant interaction might help to explain the clinical action of potencies is discussed., Competing Interests: None declared., (Faculty of Homeopathy. This article is published by Thieme.)

Introduction: Finding solutions to mitigate the impact of pollution on living systems is a matter of great interest. Homeopathic preparations of toxic substances have been described in the literature as attenuation factors for intoxication. Herein, an experimental study using Artemia salina and mercury chloride was developed as a model to identify aspects related to bioresilience., Aims: The aim of the study was to describe the effects of homeopathic Mercurius corrosivus (MC) on Artemia salina cysts hatching and on mercury bioavailability., Methods: Artemia salina cysts were exposed to 5.0 µg/mL of mercury chloride during the hatching phase. MC potencies (6cH, 30cH, and 200cH) were prepared in sterile purified water and poured into artificial sea water. Different controls were used (non-challenged cysts and challenged cysts treated with water, succussed water, and Ethilicum 1cH). Four series of nine experiments were performed to evaluate the percentage of cyst hatching. Soluble total mercury (THg) levels and precipitated mercury content were also evaluated. Solvatochromic dyes were used to check for eventual physicochemical markers of MC biological activity., Results: Significant delay ( p  < 0.0001) in cyst hatching was observed only after treatment with MC 30cH, compared with controls. This result was associated with an increase of THg concentration in water ( p  = 0.0018) and of chlorine/oxygen ratio ( p  < 0.0001) in suspended micraggregates, suggesting changes in mercury bioavailability. A specific interaction of MC 30cH with the solvatochromic dye ET33 ( p  = 0.0017) was found., Conclusion: Changes in hatching rate and possible changes in Hg bioavailability are postulated as protective effects of MC 30cH on Artemia salina , by improving its natural bioresilience processes., Competing Interests: None declared., (Faculty of Homeopathy.
