Summary
Naturopathy is a system of medicine that attributes all disease to the accumulation of unnatural substances or habits in the body and prescribes natural agents (water, air, sunlight, food, exercise, herbal medicines) as the means of cure. Its institutional history in the United States begins with Benedict Lust, a German immigrant who combined Sebastian Kneipp’s water-cure methods with homeopathy, massage, and dietary reform to found the American School of Naturopathy in New York in 1901. The movement drew on a broader nineteenth-century tradition that James Whorton has called “the Hippocratic heresy,” a cluster of alternative medical sects united by trust in the body’s natural healing power, empirical observation of outcomes, and rejection of the heroic drug-and-bleeding regime of orthodox medicine. Naturopathy’s history is marked both by genuine therapeutic insights and by the difficulty of stabilizing a broad drugless coalition into a single profession.
The Hippocratic Heresy
To understand naturopathy, it is necessary to understand the broader tradition from which it emerged. Whorton argues that the diverse alternative medical sects of nineteenth-century America (hydropaths, Thomsonians, Eclectics, homeopaths, and later naturopaths and osteopaths) were unified by three interlocking principles that he calls “the Hippocratic heresy”: trust in the body’s natural healing power (vis medicatrix naturae), empiricism (knowledge from observed outcomes rather than theoretical speculation), and holism (treating the whole person) (Whorton, 2002).
These three principles stood in explicit opposition to heroic therapy, the dominant American medical practice of the early nineteenth century, characterized by massive doses of calomel (mercury chloride), bloodletting, blistering, and purging. Benjamin Rush had prescribed calomel at ten times the standard dose and taught that nearly all diseases arose from a single cause requiring aggressive depletion (Whorton, 2002). Against this, the alternative sects argued that the physician’s role was to support nature’s healing capacity, not to override it with violent interventions.
Vitalism was the philosophical foundation shared across these traditions: the belief that living organisms are animated by a vital force distinct from mechanical or chemical processes, and that this force, not the physician, accomplishes healing (Whorton, 2002).
The Kneipp Tradition and Benedict Lust
Naturopathy’s direct lineage runs through Sebastian Kneipp insofar as Benedict Lust encountered the movement through Kneipp’s establishment at Wörishofen and returned to New York as Kneipp’s self-described emissary to “spread the Gospel of the Water Cure” (Whorton, 2002). By 1901 Lust had expanded that inheritance into a broader American system he called naturopathy.
Lust combined hydrotherapy with massage, dietary reform, and other drugless methods, then institutionalized the synthesis by opening the American School of Naturopathy in New York City in 1901, the first institution to grant the ND degree (Whorton, 2002). Lust named the movement using a term coined by John Scheel in 1895.
The term combined the Latin natura with the Greek pathos and announced its theoretical ambitions directly. Disease (pathos) would be addressed through nature, not through the drug arsenal of orthodox medicine.
Pathological Monism and Therapeutic Universalism
Naturopathy’s theoretical framework rested on what Whorton identifies as two interlocking doctrines. Pathological Monism held that all diseases share a single cause: the accumulation of morbid matter or “impurities” in the body from unnatural living, including improper diet, insufficient exercise, inadequate sunlight, exposure to toxins, and emotional stress. Therapeutic Universalism followed as its corollary: a single set of natural treatments (diet reform, water, air, light, exercise) could cure all diseases, because all diseases were manifestations of the same underlying condition. Lust called the combined causal picture “the tree of disease” (Whorton, 2002).
These doctrines served as both a therapeutic rationale and a boundary-marking device. By asserting that all disease arose from violation of natural law, naturopathy positioned orthodox medicine’s pharmaceutical and surgical interventions as at best symptomatic and at worst contributory to the underlying cause. Therapy therefore had to be directed toward inner cleansing through drugless natural means rather than pharmaceutical suppression (Whorton, 2002).
This was what gave naturopathy its characteristic blend of pathological monism and therapeutic universalism: one underlying disorder, one broad family of natural correctives (Whorton, 2002).
Russell Trall and the Natural Hygiene Tradition
The institutional lineage of American naturopathy intersects at several points with the earlier hydropathic tradition. Hydropathic theorists had already framed disease in terms of morbid matter, deficient vitality, and violations of hygienic law, creating a conceptual bridge between the water cure and later naturopathic doctrines of cleansing and natural living (Gevitz (ed.), 1990).
This lineage matters because it shows naturopathy emerging not from a single founder’s invention but from a longer tradition of hygienic reform and drugless healing that Lust reassembled under a new institutional banner (Whorton, 2002)(Whorton, 2002).
Progressive Era Politics
Naturopathy’s rhetoric was expansive rather than narrowly technical. Lust organized it as an umbrella for multiple drugless systems and insisted that pharmaceutical drugs had no legitimate place in healing, even while herbs remained acceptable as natural agents rather than drugs (Whorton, 2002)(Whorton, 2002). That combination of eclectic inclusiveness and anti-drug principle gave the movement a broader cultural ambition than a single therapeutic method could carry.
This wider ambition also helps explain why naturopathy could draw on constituencies already formed by earlier health-reform movements. Hydropathy had linked healing to patient autonomy, women’s reform culture, and the critique of unhealthy ways of living; naturopathy inherited much of that wider reformist atmosphere even as it reassembled the older currents under a new institutional banner (Gevitz (ed.), 1990)(Gevitz (ed.), 1990).
Institutional Development and Its Problems
Naturopathy’s ambition to serve as an umbrella for all natural healing systems, including homeopathy, osteopathy, chiropractic, herbalism, and dietary reform, was also a structural weakness. In 1902 Lust founded the Naturopathic Society of America (later the American Naturopathic Association) as the organizing body for diverse drugless healing systems (Whorton, 2002).
That same inclusiveness made naturopathy difficult to stabilize as a profession. What unified the movement was less a single technique than a shared commitment to drugless healing, inner cleansing, and natural therapeutics, which made the coalition intellectually rich but institutionally diffuse (Whorton, 2002)(Whorton, 2002)(Whorton, 2002).
This tension between the practical advantages of eclecticism and the institutional disadvantages of diffuse credentialing has shaped naturopathic professional development throughout the twentieth century and into the contemporary period.
Lindlahr and the Philosophical Systematization
Where Lust had organized naturopathy institutionally and Kneipp had supplied its hydrotherapeutic foundation, Henry Lindlahr gave the movement a philosophical architecture. His Philosophy of Natural Therapeutics (1918) codified the principles that would become the theoretical core of naturopathic education.
Lindlahr’s system rested on an explicitly vitalist metaphysics. He identified the vis medicatrix naturae as “the supreme Intelligence and Power acting in and through every atom, molecule and cell in the human body, which is the true healer,” and limited the physician’s role to removing obstructions so that “the healer within” could do its work (Lindlahr, Henry, 1918). This vital force was not merely an empirical observation about self-healing but a cosmic principle: “an expression of divine intelligence and will, the logos” that permeates the entire created universe (Lindlahr, Henry, 1918).
From this metaphysical base Lindlahr derived three primary manifestations of disease, corresponding to three life requirements of the cell: innervation, nutrition, and drainage. These manifest as lowered vitality, abnormal composition of blood and lymph, and accumulation of waste and morbid matter (Lindlahr, Henry, 1918). The germ theory of disease was explicitly rejected: bacteria are “not the primary causes and instigators” of disease but “the product of pathogenic conditions,” scavengers of the morbid soil in which they breed (Lindlahr, Henry, 1918).
The Laws of Cure
Lindlahr formulated the fundamental Law of Cure as “every acute disease is the result of a cleansing and healing effort of Nature,” tracing this to Hippocrates’ statement “Give me fever and I can cure every disease” (Lindlahr, Henry, 1918). This was not merely an observation about fever’s utility but a complete reframing: what orthodox medicine treated as pathology, Lindlahr treated as therapy.
He further articulated the Law of Dual Effect: every agent affecting the human organism produces two effects, a first temporary effect and a second lasting effect always contrary to the first. Stimulants cause weakness; laxatives cause constipation; antipyretics worsen the conditions they temporarily relieve (Lindlahr, Henry, 1918). From this law followed what Lindlahr considered allopathic medicine’s fundamental error: treating inflammation and fever as enemies rather than allies, suppressing them with drugs rather than cooperating with nature’s healing efforts (Lindlahr, Henry, 1918). Drug treatment, he argued, paralyzes vital force; the lasting effects of pharmaceutical intervention are always similar to disease conditions (Lindlahr, Henry, 1918).
Lindlahr’s systematization represents a distinctive moment in the history of vitalism: the translation of European vitalist philosophy into a complete American clinical system, with diagnostic criteria, treatment protocols, and a comprehensive critique of orthodox medicine.
Naturopathy and the Sectarian Problem
The post-Flexner era brought a new difficulty for all alternative medical systems. By the 1920s American public opinion had shifted, and the terms “reformed,” “sectarian,” “cultist,” and “irregular” had come to imply substandard quality, misplaced objectives, and idiosyncratic reasoning (Haller, 1994). Eclectic medicine, the botanical sect most closely related to naturopathy in philosophy and materia medica, was unable to survive this shift and closed its last school in 1939. Naturopathy faced the same hostile climate but proved more durable, in part because its broad therapeutic umbrella, encompassing dietary reform, physical culture, and hydrotherapy alongside botanical medicine, gave it a popular base that could not be captured by any single regulatory action.
The movement’s relationship to homeopathy was especially complicated. Henry Eisfelder, an MD-trained homeopath writing in 1955, warned his colleagues that chiropractors and naturopaths seeking backdoor access to state licensing through homeopathic societies represented “a cultist threat.” Their degrees came from schools that state licensing boards did not recognize, and their admission would undermine the professional status of medically trained homeopaths (Haller, John S. Jr., 2009). From the homeopathic establishment’s perspective, naturopathy occupied an ambiguous position: philosophically aligned (both shared vitalism and the vis medicatrix naturae) but institutionally threatening because it competed for the same legal-practice territory with weaker credentials.
The Third Reich Anomaly
Naturopathy’s regulatory fortunes varied dramatically by country. In 1933, the Nazi government in Germany passed a law granting naturopaths and herbalists near-equivalent status with qualified physicians, established chairs of botanical medicine in all German universities, and expanded pharmacognosy research. Rudolf Hess declared that science had “admitted failure” and that “the natural remedy” was “to return to Mother Nature” (Griggs, 1981)(Willard, 2021). British and American herbalists and naturopaths watched this development with complicated feelings: envying the legal recognition while the political context was impossible to separate from the grant. The same period saw herbalists in England made legally suspect, with the 1941 Pharmacy and Medicines Act removing herbalists’ right to supply medicines directly to patients (Willard, 2021). The juxtaposition of legal elevation in fascist Germany against legal suppression in democratic Britain illustrates how naturopathic professional recognition has depended less on therapeutic evidence than on the political and economic interests that shaped each national regulatory settlement.
The Eclectic Connection: A Living Inheritance
Naturopathy and eclectic medicine shared common ground throughout their parallel histories. Both drew on botanical medicine, both rejected mineral heroics, and both framed disease in vitalist terms. When eclectic medicine collapsed after 1939, some of its institutional energy passed into naturopathic channels.
The clearest example came in 1982, when two naturopathic physicians, Edward K. Alstat and Michael Ancharski, founded the Eclectic Institute in Portland, Oregon, explicitly reviving the materia medica of John Uri Lloyd and John King. Rather than reproducing the eclectic preparations as they had existed, they used the then-new technique of freeze-drying (lyophilization) to capture what they described as “the vital force of the plants” (Haller, 1994). The institute also undertook republication of eclectic texts. This revival represented not a simple antiquarianism but a claim that naturopathic medicine was the legitimate institutional heir to the eclectic tradition, with eclectic botanical medicines transmitted through new technology and eclectic philosophy translated into the language of contemporary naturopathic education.
The same connection appears in John Christopher’s career. Christopher received his Naturopathic Doctor degree from the Institute of Drugless Therapy in Tama, Iowa, in 1948, after having earlier received a degree in Herbal Pharmacy and the title of Master Herbalist (Willard, 2021). His School of Natural Healing, opened in 1953, drew on both the eclectic and the naturopathic inheritance. The overlap between these two traditions in mid-century practitioners suggests that the formal closure of eclectic colleges in 1939 did not end eclectic medicine so much as disperse it into the broader alternative-medicine milieu that naturopathy organized.
Homeopathy Within Naturopathic Education
As naturopathy institutionalized its professional training through the latter twentieth century, homeopathy became a formal part of the ND curriculum. By 1985, both the National College of Naturopathic Medicine in Portland, Oregon, and the John Bastyr College of Naturopathic Medicine in Seattle, Washington, had incorporated homeopathy into their full-year curricula, alongside botanical medicine, hydrotherapy, clinical nutrition, Oriental medicine, spinal manipulation, counseling, and exercise therapy (Haller, John S. Jr., 2009). The training required study of homeopathy for one full year, or alternatively seven semesters spread across the entire program (Haller, John S. Jr., 2009).
Eventually all accredited naturopathic medical schools established a department or program in classical Hahnemannian philosophy (Haller, John S. Jr., 2009). George Vithoulkas, the Greek civil engineer who became the leading advocate of high-potency Kentian homeopathy in the English-speaking world after being “discovered” at the 1974 Liga meeting in Athens, conducted seminars specifically at the Pacific College of Naturopathic Medicine, making that institution a hub for the classical homeopathic revival within naturopathic education (Haller, John S. Jr., 2009).
This integration of homeopathy into naturopathic training was not accidental. Both traditions shared vitalism, the vis medicatrix naturae, and antipathy to pharmaceutical suppression of symptoms. For the naturopathic college system, classical homeopathy offered a body of systematized philosophical literature, including Hahnemann’s Organon and Kent’s Lectures, that gave the ND curriculum intellectual depth alongside its practical clinical training.
Vitalism and the Plant-Human Relationship
David Hoffmann, in his Medical Herbalism (2003), frames a distinction between two ways of understanding the plant-human relationship that cuts directly to naturopathy’s philosophical heart. The Darwinian view, which dominates conventional pharmacology, holds that secondary metabolites evolved primarily as chemical defenses, such that plants and their users exist in “an uneasy balance of chemical power.” Against this, Hoffmann observes, “the vitalist worldview held by most herbalists and naturopaths” characterizes the relationship as coevolutionary mutualism rather than competitive defense (Hoffmann, David, 2003). This is not a trivial difference. The Darwinian framing justifies extracting and concentrating a plant’s most potent defensive compounds as “active principles.” The coevolutionary framing justifies using whole plants, complex mixtures, and lower doses, practices closer to the traditional naturopathic and eclectic approach.
The two frameworks lead to different clinical approaches, and naturopathy has historically sided with the vitalist-mutualist view: nature provides what the body needs; the physician’s role is to facilitate access to those natural provisions, not to override them with pharmaceutical extracts. Lindlahr’s rejection of germ theory, Lust’s rejection of pharmaceutical drugs, and the movement’s persistent preference for diet over drugs all express the same underlying orientation.
