Atopic dermatitis (AD) is one of the most common

Atopic dermatitis (AD) is one of the most common dermatological conditions seen in practice in both young and older patients. Up to 17% of Canadians experience atopic dermatitis at some point in their lives (, 2022). It affects 10-20% of the paediatric population and up to 3% of the adult population (Bieber, 2008). AD can present on its own, but is often a part of the atopic triad, which includes allergic rhinitis and asthma. Additionally, AD has been found to be associated with an increased risk of anxiety, depression, and suicidal ideation (Yaghmaje, 2013). A link between AD and cardiovascular conditions (cardiovascular disease, coronary artery disease, and hypertension) has been acknowledged (Silverberg, 2015).

AD is complex condition with multiple contributing factors. A singular cause has not yet been uncovered, but rather each individual may have a varied constellation of factors that lead to their development of AD. At best, it can be considered to be a T-cell driven process with epidermal barrier dysfunction.

Keeping the diversity of contributing factors in mind, it is safe to say that a cookie-cutter approach may not always be appropriate or effective in managing AD. The integrative approach to managing atopic dermatitis takes into consideration factors that may predispose the individual to AD, factors that may exacerbate AD flares, current treatment guidelines, as well as proven alternative therapies on a case-by-case basis.


Diagnosing Atopic Dermatitis

When dealing with a patient with AD, a detailed patient history is imperative. Not only will this provide the basic information needed to make a diagnosis, but also gives the practitioner clues about which therapeutic route may be most beneficial. A diagnosis of AD can be made with a detailed patient history, a physical exam of the lesion(s) including morphology and distribution, and key symptoms (Berke, 2012). The U.K. Working Party’s Diagnostic Criteria for Atopic Dermatitis is commonly used when making a diagnosis (Russel, 2001).

U.K. Working Party’s Diagnostic Criteria for Atopic Dermatitis:

  • Itchy skin
  • At least 3 of the following:
    • Onset under the age of two years
    • A history of flexural involvement
    • A history of asthma or hay fever/history of atopic disease in siblings and parents if the child is under 4 years
    • A history of dry skin in the last year
    • Visible flexural dermatitis

Common Causes of Atopic Dermatitis and Triggers

            AD is a complex condition with multiple factors that can increase the incidence and further exacerbate it. These factors include: (1) genetics and family history; (2) cutaneous barrier dysfunction and increased permeability; (3) dysregulation of the immune system; (4) environmental factors; (5) digestive impairments; (6) nutritional deficiencies; and (7) stress (Maloh, 2022).

Genetic Factors  in AD

            The incidence of AD in infants is 2.6 times greater when there is a documented family history of atopy (8). The genetic predisposition of AD has been extensively studied, and over 30 genetic loci have been identified (Løset, 2019).  Mutations in these genes can cause immune dysregulation and disruptions in the skin barrier (8). Each mutation increases the risk of developing AD by 40-50% (Palmer, 2008). Of all the genetic loci that have been identified, the strongest genetic risk factor is due to mutations of the filaggrin gene (4).

Filaggrin is a protein responsible for collecting keratin filaments which are subsequently cross-linked to create scaffolding for the extracellular lipid matrix on the outermost layers of the dermis (38). Proper skin barrier function is dependent on a functional filaggrin gene (Maloh, 2022). In addition to aggregating keratin filaments, the breakdown product of filaggrin is a component of natural moisturizing factors (NMFs) which play a role in the skin’s ability to retain moisture and maintain an acidic surface pH (5).

Mutations in the filaggrin gene disrupt the stratum corneum, making it more susceptible to infiltration by pathogens, allergens and toxins (Kawasaki, 2012). This lays the groundwork for a chronically inflamed environment. Initially, the infiltration causes a TH1 immune response which produces inflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor beta (TNFB) (Traub, 2016). The presence of this inflammation paired with increased trans-epidermal water loss (TEWL) compromises the protective effective of the skin barrier. If inflammation is present for long enough, the TH1 response switches to a TH2 response, represented by basophils, monocytes, eosinophils, and other cytokines that propagate inflammation and pruritus (Elias, 2009).

In addition to mutations in the filaggrin gene, other components that can affect the protective barrier including changes in lipid composition, increased skin pH, alterations in the skin microbiome, itching, and weakened tight junctions (Zhu, 2018).

AD and Diet    

            Dietary deficiencies and food allergies have long been posited as a contributing factor in atopic dermatitis. Individuals with atopic dermatitis are more likely to experience gastrointestinal issues, such as diarrhea, and vomiting compared to a control group (Caffarelli, 1998). On the flip side, individuals with functional gastrointestinal disorders, such as IBS and constipation, tend to have a higher prevalence of atopic dermatitis compared to individuals without (45).

While there seems to be a connection between digestive system and atopic dermatitis, it is poorly understood and there isn’t enough evidence to support current hypotheses. One popular thought  is that there is a link between increased intestinal permeability (or “leaky gut”) and atopic dermatitis. Cytokines that are associated with atopic dermatitis (IL-4 and IL-13) have been found to up regulate claudin-2, a protein associated with intestinal permeability (Maloh, 2022). Another association that has been explored is food allergies and AD. There are studies that suggest that a disrupted skin barrier allows for allergens to penetrate the skin, leading to increased systemic inflammation and increased sensitization for food allergens (Bergmann, 2013). Foods that are commonly associated  with atopic dermatitis are peanuts, dairy, and eggs (Burks, 1998)

Environmental  Triggers

Atopic dermatitis is affected as much by the external environment as it is the internal. Various factors can decrease or worsen exacerbations, including humidity, temperature, and aeroallergen exposures.

Within the home environment, it can be helpful to keep a humidifier in the patient’s room (Gallay,  2020)  and avoid air conditioning.  While air conditioning hasn’t been found to worsen AD symptoms, it can weaken the skin barrier by increasing skin pH and reducing the degradation of filaggrin into NMFs  (natural moisturizing factors)  (Gallay 2020).

Exposure to phthalates, or a chemical additive to plastics, has also been linked with an  increased incidence of AD (Wang, 2014). Phthalates can be found in multiple places within the home, including toys, food wrappings, cosmetics, and dust (Wang, 2014). It has been found that early  exposure to monobenzyl phthalate is significantly associated with the development of AD (Wang, 2014).  Similarly, there is  a  strong association with AD development and the exposure to butyl benzyl phthalate (Bornehahg, 2004). It is thought that phthalate may increase the incidence of AD because it stimulates the thymic stromal lymphopoietin (TSLP), a cytokine that triggers a TH2 response (Shigeno, 2009).

 Therapeutic Interventions for Treating Eczema

            The nature of atopic dermatitis is that it is a relapsing and remitting condition; there is no cure (Weinsteine, 2020). Conventional therapies aim at minimizing and controlling flares (Weinstein, 2020) while the holistic approach aims at restoring balance within the body and removing obstacles to cure.

Conventional Approach

            The first-line therapy for mild-moderate atopic dermatitis is topical corticosteroids. The appropriate agent is selected based on factors such as patient age, areas of body treated, xerosis and patient preference (Weinstein, 2020). Typically, the selected agent will have a trial period of 1-2 weeks. If there is no improvement or response within that time, another agent or therapy can be selected. Other options that the practitioner has for mild-moderate atopic dermatitis include topical calcineurin inhibitors and topical PDE4 inhibitors. For refractory and severe AD, the practitioner can consider phototherapy with a broad- and narrowband UVB, biologic agents in patients over 12 years old, or other systemic agents such as methotrexate (Weinstein, 2020). The practitioner must proceed with caution when selecting a systemic agent due to significant adverse effects and the requirement of regular monitoring (Weinstein, 2020).

Traditional Chinese Medicine

Traditional Chinese Medicine views healing through the lens of bringing balance to the body. The underlying pattern of atopic dermatitis is the combination of heat, damp, and wind, and thus herbs that have the energetic functions of cooling, drying, and dispelling wind are used. These herbs tend to have anti-inflammatory and antibiotic properties (Chen, 2015). A common combination of herbs include Xiao Feng san – clear wind powder (Chen, 2016; Cheng, 2011). Depending on the underlying pattern  of  the  atopic dermatitis, additional herbs can be added at the practitioners’ discretion.

Heat and predominantly heat toxicity Honeysuckle – jin yin hua

Anti-inflammatory and immuno-regulatory properties. (Muluye, 2014)


Combine with lian qiao.  (Forsythia. Fruit)

Anti-allergic and antibacterial. Properties (Sung, 2016; Kuo, 2014)

Damp and predominantly damp heat Use the “three yellows” Huang qin, Huang lian, Huang bai

Antbiotic and anti-inflammatory effects

Severe damp heat and toxicity Huang lian jie du tang – reduce toxicity; anti-allergic and anti-inflammatory effects (Zeng,  2009; Chen, 2016)

Naturopathic Approach

            The naturopathic approach to atopic dermatitis focuses on finding the root cause of the individuals’ AD, removing obstacles/barriers to healing, and supporting the body’s natural ability to heal itself. In a given patient, that may look like adding supplements/herbs/nutrient-rich foods to overcome any deficiencies and to stimulating healing; adapting the external environment to remove/reduce triggers; providing options for stress reduction; and offering topical therapies to bring relief to existing lesions.

The following table of treatments is adapted from the suggestions of Maloh, et al. While it is by  no means a conclusive list, it offers practical therapies that can be used on their own  or in  conjunction  with conventional topical therapies.
