BACKGROUND: Menopause is a physiological event that marks the end of a woman's reproductive stage in life. Vasomotor symptoms and changes in mood are among its most important effects. Homeopathy has been used for many years in treating menopausal complaints, though clinical and pre-clinical research in this field is limited. Homeopathy often bases its prescription on neuropsychiatric symptoms, but it is unknown if homeopathic medicines (HMs) exert a neuroendocrine effect that causes an improvement in vasomotor symptoms and mood during menopause. OBJECTIVES: The study's objectives were to address the pathophysiological changes of menopause that could help in the understanding of the possible effect of HMs at a neuroendocrine level, to review the current evidence for two of the most frequently prescribed HMs for menopause (Lachesis mutus and Sepia officinalis), and to discuss the future directions of research in this field. METHODS: An extensive literature search for the pathophysiologic events of menopause and depression, as well as for the current evidence for HMs in menopause and depression, was performed. RESULTS: Neuroendocrine changes are involved in the pathophysiology of vasomotor symptoms and changes in mood during menopause. Gonadal hormones modulate neurotransmitter systems. Both play a role in mood disorders and temperature regulation. It has been demonstrated that Gelsemium sempervirens, Ignatia amara and Chamomilla matricaria exert anxiolytic effects in rodent models. Lachesis mutus and Sepia officinalis are frequently prescribed for important neuropsychiatric and vasomotor symptoms. Dopamine, a neurotransmitter involved in mood, is among the constituents of the ink of the common cuttlefish, Sepia officinalis. CONCLUSION: Based on all the pathophysiologic events of menopause and the improvement in menopausal complaints that certain HMs show in daily practice, these medicines might have a direct or indirect neuroendocrine effect in the body, possibly triggered via an as-yet unidentified biological mechanism. Many unanswered questions in this field require further pre-clinical and clinical research.

BACKGROUND: Bovine mastitis is characterized by an inflammatory process in the mammary gland and represents one of the main diseases affecting a dairy herd. Management of mastitis is most commonly via antibiotics, but the rising incidence of multiple antibiotic resistance (MAR) means that additional options are needed. Homeopathic products can be administered in dairy farming for a range of clinical reasons and may be preferential due to the absence of residues. OBJECTIVES: The aim of this study was to assess the potential of a novel homeopathic complex medicine in managing bovine mastitis. METHODS: Twenty-four lactating Holstein cows with mastitis were divided into two groups: the homeopathic complex group received a homeopathic complex daily for 60 days at a dose of 20 g/d; the placebo group received the calcium carbonate vehicle without homeopathic medicines at the same dose and repetition. The main outcome measure was somatic cell count (SCC; cells/mL), with additional outcome measures including milk production (kg/d), milk constituents (percentage of protein, fat, lactose and total milk solids), and serum levels of cortisol, glucose, ammonia and lactic acid. All outcomes were measured at the beginning of the study and after 30 and 60 days. Milk samples were also collected from all animals at the beginning of the study, confirming a high (>0.2) MAR index for isolated bacterial cultures. RESULTS: Assessment of SCC showed a statistically significant difference favoring the homeopathic complex versus placebo group at day 60. A reduction in serum cortisol levels and an increase in fat, lactose and total milk solids in animals treated with the homeopathic complex at day 60 were also seen. Other outcome measures did not show statistically significant inter-group differences. CONCLUSION: The results of this non-randomized, open-label, placebo-controlled trial suggest the potential for a novel homeopathic complex medicine in management of multiple antibiotic-resistant bovine mastitis, thus offering dairy farmers an additional option to antibiotics and making dairy products safer for consumer health and milk production more sustainable.

INTRODUCTION: Aspirin is one of the most commonly used drugs worldwide. It is known to present antipyretic, anti-inflammatory and anti-thrombotic actions, making it extremely useful in a wide range of clinical contexts. Interestingly, homeopathically prepared Aspirin 15cH has been found to have a pro-thrombotic effect in rats, raising the hypothesis that Aspirin 15cH could also modulate the activity of inflammatory cells in different pathological processes. OBJECTIVE: Our objective was to assess what effect Aspirin 15cH has on RAW 264.7 macrophages in vitro. METHODS: The effects of Aspirin 15cH on biochemical and morphological activities of lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages were evaluated. These effects were compared with unchallenged macrophages (negative control), untreated LPS-stimulated macrophages, macrophages treated with succussed water (vehicle control), or aspirin 200 µg/mL (pharmacological inhibitor of LPS activity). Cell morphology (adhered cell area and cytoskeleton arrangements), cell viability, toll-like receptor-4 (TLR-4) expression, and the production of nitric oxide, cytokines and intracellular reactive oxygen species were assessed. RESULTS: Aspirin 15cH reduced the number of cells expressing TLR-4 on the surface (p = 0.03) and induced a "columnar" morphology of macrophage pseudopods, indicating changes in cytoskeleton arrangement. When cells were treated with both Aspirin 15cH and LPS, cell morphology became heterogeneous, suggesting that sub-populations of cells had differing sensitivities to LPS or Aspirin 15cH. Exposure of the cells to LPS alone, succussed water or aspirin 200 µg/mL produced effects consistent with the literature. CONCLUSION: Aspirin 15cH, aspirin 200 µg/mL, LPS and succussed water appear to act as independent stimuli able to induce different patterns of macrophage response. Aspirin 15cH induced changes suggestive of M2 polarization of the macrophages (i.e., toward a wound healing or tissue repair, rather than inflammatory, phenotype). These preliminary findings need to be confirmed in further specific studies.

Homeopathy has been a medical practice recognized worldwide for more than two centuries, performing care, teaching and research activities in several health institutions and medical schools. It employs a clinical approach based on heterodox and complementary scientific principles (principle of therapeutic similitude, homeopathic pathogenetic experimentation, use of individualized medicines and dynamized or potentiated doses), with the aim of awakening a curative response in the body against its own disorders and/or diseases. Based on different premises from those used by conventional medical practice, homeopathy is often the target of unfounded and widespread criticism from individuals who systematically deny homeopathic assumptions and any scientific evidence that proves them due to their pseudoskeptical and pseudoscientific stance, which prevents a correct and bias-free analysis. In order to enlighten doctors, researchers, health professionals and the general public, demystifying culturally rooted dogmatic positions and the pseudoskeptical fallacies that "there is no scientific evidence for homeopathy" and "homeopathy is placebo effect", the Technical Chamber of Homeopathy of the Regional Council of Medicine of the State of São Paulo (TC-Homeopathy, Cremesp) prepared the "Special Dossier: Scientific Evidence for Homeopathy" in 2017, made available in three independent editions (online in Portuguese and English; printed in Portuguese) in the Revista de Homeopatia (São Paulo). Then, the dossier was published in Spanish in the La Homeopatía de México journal in 2023 in an edition commemorating the journal's 90th anniversary. Encompassing nine narrative reviews on the various lines of homeopathy research and containing hundreds of scientific articles describing experimental and clinical studies, the Dossier highlighted the state of the art of homeopathic science. Proving and expanding this scientific evidence in 13 chapters, the current work aims to update and clarify knowledge in the area. In addition to elucidating the epistemological premises of the homeopathic model in detail, the work describes the various aspects of basic and clinical research which endorse homeopathic practice and treatment in a continuum of information, data and bibliographic references. The work discusses various topics related to research in homeopathy, covering everything from "homeopathic clinical epidemiology" to "pseudoskeptic and pseudoscientific strategies used in attacks on homeopathy", including "pharmacological basis of the principle of similitude", "experimental studies in biological models", "randomized controlled clinical trials", "systematic reviews, meta-analyses and global reports" and "observational studies", among others. In view of the fact that it becomes fruitless and tiring to describe and analyze all the studies and experiments from the different research lines, we suggest and systematize in the different chapters for those who want to delve deeper into the areas of interest, bibliographical surveys of existing literature through the different databases. As we reiterate throughout the work, despite the difficulties and limitations that exist in developing research in homeopathy due to both methodological aspects and the lack of institutional and financial support, the set of experimental and clinical studies described is indisputable proof that "there is scientific evidence for homeopathy" and "homeopathy is not placebo effect", contrary to falsely disseminated prejudice. However, new studies must continue to be developed to improve clinical practice and elucidate peculiar aspects of the homeopathic paradigm. Acting as an integrative and complementary therapy to other specialties, homeopathy can add efficacy, effectiveness, efficiency and safety to medical practice, acting in a curative and preventive manner, reducing symptomatic manifestations and the predisposition to falling ill, with low cost and minimal adverse events, helping doctors to fulfill their "highest and only mission, which is to make sick people healthy, which is called healing" (Samuel Hahnemann, Organon of Medicine, § 1).

La Homeopatía ha sido una práctica médica de renombre mundial durante más de dos siglos, desarrollando actividades asistenciales, docentes y de investigación en varias instituciones de salud y escuelas de medicina. Emplea un enfoque clínico basado en principios científicos heterodoxos y complementarios (principio de similitud terapéutica, experimentación patogénica homeopática, uso de medicamentos individualizados y dosis dinamizadas), con el objetivo de despertar una respuesta curativa del organismo frente a sus propios trastornos o enfermedades. Partiendo de premisas diferentes a las empleadas por la práctica médica convencional, la Homeopatía suele ser objeto de críticas infundadas y generalizadas por parte de individuos que niegan sistemáticamente los supuestos homeopáticos y cualquier evidencia científica que los demuestre porque tienen una postura pseudoescéptica y pseudocientífica que impide un análisis correcto y desprejuiciado. Son "pseudoescépticos" disfrazados de "pseudocientíficos". Ilustrar a médicos, investigadores, profesionales de la salud y al público en general, desmitificando las posturas dogmáticas culturalmente arraigadas y las falacias pseudoescépticas de que "no hay evidencia científica en la Homeopatía" y "la Homeopatía es un efecto placebo", en 2017, la Cámara Técnica de Homeopatía del Consejo Regional de Medicina del Estado de São Paulo (CT-Homeopatía, Cremesp) elaboró el "Dossier Especial: Evidencia Científica en Homeopatía", disponible en tres ediciones independientes (en línea en portugués e inglés; impresa en portugués) en la Revista de Homeopatía (São Paulo). En 2023, el dossier fue publicado en español en la revista La Homeopatía de México, en una edición conmemorativa del 90 aniversario de la revista. Abarcando nueve revisiones narrativas sobre las diversas líneas de investigación en Homeopatía, que contienen cientos de artículos científicos que describen estudios experimentales y clínicos, el dossier destacó el estado del arte de la ciencia homeopática. Demostrando y ampliando esta evidencia científica, el presente trabajo ("La Homeopatía no es Efecto Placebo": Comprobación de las Evidencias Científicas en Homeopatía) pretende esclarecer los conocimientos en el área en trece capítulos. Además de dilucidar en detalle las premisas epistemológicas del modelo homeopático, el trabajo describe, en un continuo de información, datos y referencias bibliográficas, los diversos aspectos de la investigación básica y clínica que avalan la práctica y el tratamiento homeopático. Discutiendo diversos temas relacionados con la investigación en Homeopatía, el libro aborda desde la "epidemiología clínica homeopática" hasta las "estrategias pseudoescépticas y pseudocientíficas utilizadas en los ataques a la Homeopatía", pasando por el "fundamento farmacológico del principio de similitud", "estudios experimentales en modelos biológicos", "ensayos clínicos controlados aleatorizados", "revisiones sistemáticas, metaanálisis e informes globales" y "estudios observacionales", entre otros. Como hemos reiterado a lo largo del libro, a pesar de las dificultades y limitaciones en el desarrollo de la investigación en Homeopatía, tanto por aspectos metodológicos como por la ausencia de apoyo institucional y financiero, el conjunto de estudios experimentales y clínicos descritos es una prueba irrefutable de que "existen evidencias científicas en Homeopatía" y "la Homeopatía no es efecto placebo", contrariamente al prejuicio falsamente difundido. Actuando como terapia integradora y complementaria a otras especialidades, la Homeopatía puede agregar eficacia, efectividad, eficiencia y seguridad a la práctica médica, reduciendo las manifestaciones sintomáticas y la predisposición a la enfermedad, con bajo costo y mínimos eventos adversos.
