ABSTRACT

The text seeks to clarify for the medical community and health professionals the assumptions and scientific evidence of homeopathy which, despite being part of the list of Brazilian medical specialties since 1980, is not taught in most medical schools. Associated with this gap in the education of medical students, which is reflected in the lack of information and ignorance of future doctors, the application of assumptions different from those propagated by hegemonic medicine, contributing to the dissemination of prejudices rooted in the medical culture. This distance hinders undergraduates and graduates from learning a bi-secular therapy that should be part of the current therapeutic arsenal. Employing a principle of healing that stimulates the organism to react against its own disorders and valuing the individuality of the diseased in its multiple aspects, the homeopathic method of treatment favors the doctor-patient relationship and encourages holistic reasoning in the understanding of the complex phenomenon of human illness, providing a low-cost therapy, with a low risk of adverse events, which increases the clinical resolution of diseases in general. This narrative review of the literature was developed to correlate homeopathic assumptions with the scientific evidence that supports them, describing hundreds of experimental and clinical studies that demonstrate the efficacy, efficiency, and safety of individualized homeopathic treatment.
