The Body Isn't the Enemy: Coleen Murphy on Strengthening, Not Suppressing, Autoimmune Disease

"First, do no harm" is more than a principle Coleen Murphy, ND, LAc, recites — it's the filter she applies every time a new autoimmune patient sits across from her. Too many of them arrive having already spent months or years on prednisone or methotrexate, grateful for whatever relief those drugs provided, uncertain about what comes next. What strikes Murphy about these cases isn't the severity of the diagnosis. It's how rarely anyone has asked — genuinely asked — why the immune system turned against the body in the first place. The question itself implies a different paradigm: one where the immune system isn't a malfunction to be quieted, but a signal to be understood.

Dr. Murphy is a naturopathic doctor and licensed acupuncturist at NatMedWorks in San Juan Capistrano, California, where she has spent decades applying root-cause thinking to some of the most difficult diagnoses in medicine. Ulcerative colitis, rheumatoid arthritis, Hashimoto's thyroiditis, psoriasis, lupus — conditions that most providers manage indefinitely, Murphy approaches as problems with identifiable, addressable origins. Her clinical toolkit spans botanical medicine, acupuncture, nutritional therapy, and lifestyle medicine. But before any of it comes into play, she does something that takes longer than a standard appointment allows: she listens to the whole story.

Evaluating Everything Before Treating Anything

Naturopathic medicine's intake process looks nothing like a standard 15-minute appointment. Before Murphy considers any treatment, she conducts a thorough review of systems that covers not just the presenting condition, but the patient's complete physical, emotional, and environmental history. What they eat, how they sleep, what stressors they carry, which medications they've taken over the years, their family history of autoimmune disease, their personal goals for treatment — all of it informs how she conceptualizes a case. No two autoimmune presentations are the same, and no protocol drawn from a textbook will serve every patient equally.

"My approach as a naturopathic doctor when faced with an autoimmune condition is to first evaluate the whole person. I complete a thorough intake and review of systems, and seek to understand the patient and their treatment goals. The primary goal of naturopathic medicine is always to 'First, do no harm'. Too often the first line of treatment for autoimmune diseases are medicines like prednisone and methotrexate that may provide short term relief but can create a host of unintended side effects."

This philosophy stands in direct contrast to how autoimmune disease is typically managed conventionally. The standard treatment algorithm for conditions like ulcerative colitis, rheumatoid arthritis, and lupus begins with anti-inflammatory and immunosuppressive medications — corticosteroids like prednisone and disease-modifying agents like methotrexate. These drugs are often effective at blunting acute inflammation and buying symptomatic relief, but they come with significant long-term costs: bone density loss, increased susceptibility to infection, metabolic disruption, and in some cases, heightened risk of malignancy with extended use.

The naturopathic model reframes this as a signal problem: suppressing symptoms without investigation leaves the underlying driver untouched. Understanding what triggered the immune dysregulation — whether it's a permeable intestinal barrier, chronic unresolved stress, environmental toxin exposure, food sensitivities, or the phenomenon of molecular mimicry — is the non-negotiable first step before any protocol is designed. A 2025 review published in Archives of Rheumatology examined the gut-joint connection in rheumatic diseases, demonstrating that gut microbiota composition directly shapes systemic immune activation — the same activation driving joint destruction in rheumatoid arthritis.^[1] The implication is uncomfortable for a strictly symptom-management paradigm: treating the joints without addressing the gut leaves the root mechanism intact.

For patients coming from years of conventional care, this thorough intake is itself therapeutic. Many arrive carrying a diagnosis but no explanation — told what they have, rarely told why. Murphy's process gives patients a framework for understanding their own condition, which research consistently identifies as a predictor of better treatment adherence and outcomes. Understanding what a naturopathic doctor does — and how their assessment differs from a conventional intake — is often the first step patients take toward a different kind of care.

Finding the Weak Link: Why Suppression Misses the Point

"An auto-immune condition is the body attacking itself. The treatment is to strengthen the individual and not to suppress the immune system. Returning to the UC example, in the naturopathic model, we don't suppress the immune system, but rather find the weak link and focus there. Often this involves 'healing and sealing' the permeability of the intestinal lining and promoting gut microbiome health to restore balance of gut microbiota."

Murphy's clinical framework inverts the conventional model at its foundation. Rather than viewing the immune attack as the disease itself — and suppressing it accordingly — she views it as a downstream consequence of something the body lacks or cannot adequately regulate. The autoimmune response is a symptom of an upstream failure. Identify that failure, address it directly, and the immune system can begin to reregulate rather than simply being overridden by medication. This is why "strengthening the individual" is the goal rather than quieting the immune response.

In ulcerative colitis and many other autoimmune conditions, that upstream failure frequently involves intestinal permeability — commonly called "leaky gut." The intestinal barrier is a single-cell-thick layer of epithelial cells held together by tight junction proteins. When those proteins are disrupted — by prolonged NSAID use, repeated antibiotic courses, dietary factors, chronic stress, or environmental exposures — molecules that should remain inside the gut lumen pass into systemic circulation. The immune system, encountering these foreign particles, mounts an inflammatory response. Over time, in genetically susceptible individuals, that inflammation becomes self-perpetuating and is directed at the body's own tissues.

The science supporting this mechanism has become increasingly rigorous. Zonulin — a protein that modulates intestinal tight junction permeability — has been identified as a biomarker elevated across numerous autoimmune conditions, from celiac disease to type 1 diabetes to multiple sclerosis. Research published in Current Medicinal Chemistry demonstrated that blocking zonulin signaling with the inhibitor larazotide (AT-1001) reduced systemic inflammatory markers across multiple inflammatory conditions, providing direct confirmation that barrier dysfunction functions not merely as a feature of autoimmune disease but as a likely causal driver.^[2] A 2025 review in Frontiers in Immunology extended this framework to neurological autoimmune disease, finding that gut microbiota dysbiosis correlates with disruption of the blood-brain barrier itself — confirming that the gut-permeability mechanism operates systemically, not just locally in the GI tract.^[3]

For Murphy, "healing and sealing" the gut lining is therefore not a peripheral adjunct to autoimmune treatment — it is central to it. Protocols focused on intestinal barrier repair typically incorporate targeted probiotics, L-glutamine to support tight junction integrity, zinc carnosine, and the careful removal of dietary and environmental triggers perpetuating the permeability. Understanding what is driving the barrier dysfunction — and addressing it systematically — is what separates a root-cause approach from one that simply manages the inflammation those leaks create. This investigative approach is also what distinguishes Murphy's work from that of practitioners focused exclusively on inflammation suppression; the broader naturopathic conversation about immune retraining reflects growing clinical recognition that the immune system's behavior can be genuinely changed, not just chemically overridden.

The Full Treatment Plan: Lifestyle, Stress, and Anti-Inflammatory Nutrition

"A naturopathic doctor will treat the whole person, in the case of ulcerative colitis our treatment plan will include lifestyle optimization, stress management, emotional support as well as anti-inflammatory diets, which all contribute to modulating gut permeability."

Here is where the whole-person model becomes most practically visible. A naturopathic treatment plan for ulcerative colitis is not a supplement list. It is a coordinated architecture of dietary change, stress regulation, sleep hygiene, emotional support, and targeted botanical and nutritional medicine — designed to work simultaneously on the multiple systems that influence gut permeability and immune function. Each component reinforces the others.

Diet is typically the most visible lever, and in inflammatory bowel conditions it carries significant therapeutic weight. The Autoimmune Protocol (AIP) diet — which removes grains, legumes, nightshades, dairy, and eggs during an elimination phase — has received increasing clinical attention as a structured way to reduce intestinal permeability and systemic inflammation in IBD. A 2025 review in Nutrients examined how dietary patterns shape the gut microbiome in inflammatory bowel disease, finding that anti-inflammatory diets rich in fiber, fermented foods, and polyphenols were associated with greater microbial diversity and reduced inflammatory cytokine levels compared to standard Western dietary patterns.^[4] The mechanism is intuitive: what reaches the gut consistently either supports or disrupts the microbial communities responsible for regulating immune tone.

Stress, however, is a driver that dietary changes alone cannot fully address — and one that is frequently underestimated in clinical practice. The enteric nervous system, sometimes called the "second brain" of the gut, contains hundreds of millions of neurons and communicates directly with the immune cells lining the intestinal wall. Chronic psychological stress activates the hypothalamic-pituitary-adrenal (HPA) axis, elevating cortisol and a cascade of downstream inflammatory cytokines that compromise tight junction integrity. In patients with active UC, stress doesn't just worsen symptoms subjectively — it measurably increases intestinal permeability and alters microbiome composition in ways that prolong flares. This bidirectional gut-brain relationship means that treating the gut without addressing the stress perpetuating its dysfunction is treating half the problem. Functional medicine research on autoimmune root causes consistently identifies psychosocial stress as a co-trigger in genetically susceptible individuals.

Murphy's approach to stress management is specific rather than generic — not an instruction to "reduce stress" but the integration of concrete therapeutic tools: therapeutic breathwork, somatic practices, acupuncture, and in appropriate cases, referral for psychotherapy or trauma-informed care. The acupuncture component of her practice contributes here in multiple directions. Traditional Chinese medicine has always treated the gut and immune system as deeply interconnected: the Spleen and Stomach meridians govern digestion, immunity, and the transformation of nutrients. Needling specific points has been shown to modulate vagal tone and reduce inflammatory signaling — mechanisms that align directly with what the dietary and stress interventions are also targeting, without adding pharmaceutical burden to the treatment plan.

The emotional support dimension is often the piece that surprises patients most — not because it feels unusual in a holistic context, but because it is so rarely part of any prior conversation about their condition. Living with an autoimmune disease is frequently isolating. Many patients spend years in diagnostic limbo, told their symptoms are anxiety or stress or just one of those things, uncertain whether they will ever feel consistently well again. Murphy's intake is explicitly designed to surface that history — not just to catalog symptoms, but to understand what the patient has been through and what they most need from a treatment relationship. Research published in Frontiers in Endocrinology in 2026 confirmed that gut microbiota composition is a key nutritional determinant of autoimmune thyroid disease, and that diet-based modulation of the microbiome produces measurable shifts in immune markers^[5] — a finding that resonates far beyond thyroid conditions. In Hashimoto's and other autoimmune conditions, the gut-immune axis is the shared terrain. The gut-skin connection in eczema and psoriasis follows the same logic: different tissues, same root mechanism.

The Practitioner Your Body Has Been Waiting For

What Coleen Murphy offers patients with autoimmune conditions is something the conventional model rarely provides: time, and a genuine curiosity about why. Why did the immune system begin attacking this tissue? Why did this person's gut lining become permeable when another's did not? Why are the symptoms worse in periods of stress and better when diet improves? These are not rhetorical questions for Murphy — they are the clinical questions that guide every treatment decision she makes.

The immune system is not malfunctioning randomly. In the naturopathic model, there is always a reason the body turned against itself, and in the overwhelming majority of cases, that reason is addressable. The work is methodical: evaluate the whole person, identify the weak link, and build a treatment plan that strengthens what is deficient rather than suppressing what is reactive. Patients who have spent years being managed without answers may find this framework disorienting at first — but for many, it is also the first time a clinician has treated their condition as something they can meaningfully participate in resolving.

If you're navigating an autoimmune diagnosis and looking for a practitioner who will investigate rather than simply suppress, the best holistic practitioners for autoimmune support represent a growing community of clinicians who share Murphy's root-cause philosophy. The body, in her framework, is never the enemy. It is asking for something specific. The work is figuring out what.
