Multiple myeloma (MM) is the second most common type of cancer among hematological malignancies and is difficult to treat. Although controversial in nature, homeopathy's effects have been tested on a wide range of cancer cell types , as well as clinically. However, homeopathic medicines have yet to be tested in MM cells. In this preliminary study, we investigated the effects of , , and 200C on a human MM cell line.

 Uterine fibroids are benign gynecological tumours that arise in the uterine smooth muscle tissue and are characterized by the production of excessive quantities of extracellular matrix. Various therapeutic options, from medical management to surgical intervention, exist for uterine fibroids, for which homeopathy has emerged as a promising therapeutic option in patient-centered care.

Dengue, a hyperendemic arbovirus thriving in tropical and sub-tropical climates globally, has seen a significant surge in Brazil over the past 5 years. Presently, the country faces an epidemic, posing a huge challenge to Public Health authorities due to the potentially lethal nature of severe infections. Based on Hahnemannian concepts and on the historically reported efficacy of homeopathy in fighting epidemics, this study aimed to provide supporting evidence for a homeopathic genus epidemicus approach to prevent severe forms of dengue. Symptoms related to the severe phase of the disease were prioritised in the repertorisation: () received the highest total symptoms score (43 points from 21 symptoms) followed by (31/13) and (29/14). In the asymptomatic population exposed to the etiological agent, the use of might contribute as an additional strategy in the prophylaxis of dengue.

 The Modified Naranjo Criteria for Homeopathy (MONARCH) inventory is a novel and useful tool for assessing the likelihood of a causal relationship between the homeopathic intervention and the ultimate clinical outcome.

 This study presents and analyzes the content of an online Evidence Gap Map (EGM), "", which graphically represents evidence from systematic reviews (SRs) of human clinical trials in homeopathy that were published from 1991 to 2021. The EGM was built according to the guidelines of the International Initiative for Impact Evaluation (3ie), adapted for complex interventions, to represent visually relevant evidence and research gaps.

 In 2020, a 26,849-ha state park in Mato Grosso do Sul state, Brazil, had 30% of its area damaged by fire. A homeopathic complex formulation was applied at strategic point locations in the park's springs or watercourses, aiming to mitigate the fire damage to the flora and fauna as quickly as possible. The duration of the homeopathic signal at each point was assessed using an established solvatochromic dye technique.

 The study was undertaken to evaluate the protective effect of (EP) 30C on the incidence of dengue fever.

 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 (, 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.

 Complementary and alternative veterinary medicine (CAVM) has been intensively used, and there is currently an increasing demand for a more rigorous approach regarding its clinical effectiveness.

 In the last 2 years of the pandemic, a wide range of cases of post-COVID functional gastrointestinal disorders (PC-FGIDs) has been reported.

 Over the past decade, research using various methods has claimed the material nature, including nanoparticles (NPs), of high homeopathic potencies. The current study aims to verify these findings using NP tracking analysis (NTA).

Homeopathy was introduced in Brazil with the French doctor Benoît Jules Mure's arrival in 1840 and was officially recognised in 1980 as a medical specialty by Brazilian regulatory authorities. Public health policies played an important role in incorporating homeopathy into the Brazilian Unified Health System (SUS), emphasising homeopathy's coherence with SUS's fundamental principles and with other national health policies. Homeopathy is supported by the guidelines of the National Primary Health Care Policy and the National Policy on Integrative and Complementary Practices, and its offer in the SUS has been recognised since 2006. Challenges persist, however, such as the low prevalence of the use of homeopathy, lack of investment in professional training and under-reporting of homeopathy outpatient appointments. Investments in disseminating information on homeopathic philosophy and raising awareness among managers and health professionals are essential to strengthen its presence in the Brazilian public health system.

 , , , , and are frequently prescribed homeopathic medicines; however, their symptoms, as mentioned in different homeopathic literature works, have rarely been investigated systematically. Likelihood ratio (LR), based on Bayesian statistics, may reflect a better estimation of the strengths of symptoms than the existing entries in the homeopathic literature.

 Coronavirus disease 2019 (COVID-19), a disease caused by the SARS-CoV-2 coronavirus, was declared a pandemic in March 2020, posing significant challenges globally. Homeopathy has historical relevance in epidemic management. In response, the government of the state of Santa Catarina, Brazil, distributed 1M as a potential prophylactic intervention for COVID-19.
