Abstract The concept of antidotes in homeopathy holds a central place in classical doctrine and daily clinical practice, yet remains largely unexplored in scientific literature. Antidotes are traditionally defined as substances, remedies, environmental factors or physiological and emotional influences capable of suppressing, altering or interrupting the action of a homeopathic medicine. From a classical homeopathic perspective, any factor capable of modifying the totality of symptoms—thereby influencing remedy selection and follow-up—may be regarded as a potential antidoting influence. Unlike conventional pharmacological antidotes, which act through molecular interactions, homeopathic antidoting is conceived as an interference with the organism's adaptive and regulatory response. This review revisits the historical foundations of antidotes, examines their clinical importance and explores potential scientific re-interpretations grounded in contemporary neurobiology, psychophysiology and systems medicine. Classical authors, including Hahnemann, Kent, Allen and Boericke, are critically reviewed, and the phenomenon of antidoting is discussed in light of stress physiology, placebo–nocebo mechanisms, hormesis and network regulation. We propose that antidotes represent early empirical descriptions of system-level modulation rather than substance antagonism. Finally, research perspectives are outlined to encourage methodological investigation of antidoting using modern biomedical tools.
