Abstract
Eczema, or atopic dermatitis, is a chronic inflammatory skin condition characterized by itching, redness, and recurrent lesions. While modern treatments aim to alleviate symptoms and control inflammation, Ayurvedic approaches address root causes, focusing on dietary, lifestyle, and herbal interventions. This review outlines the pathophysiology, diagnosis, and treatment options for eczema, integrating modern and Ayurvedic perspectives.
1. Introduction
Eczema, primarily atopic dermatitis, affects millions globally, causing significant discomfort and impacting quality of life. Characterized by pruritus, erythema, and lesions, eczema has a multifactorial origin, including genetic, environmental, and immunological factors. Ayurveda describes eczema as Vicharchika, a manifestation of Pitta and Kapha dosha imbalances. This article provides a thorough examination of eczema's etiology, clinical presentation, and integrative treatment options through modern and Ayurvedic lenses.

2. Pathophysiology
2.1 Modern Perspective
Eczema involves a complex interaction of genetic susceptibility, skin barrier dysfunction, and immune dysregulation1. Mutations in the FLG gene, which codes for filaggrin, weaken the skin’s barrier, leading to increased moisture loss and allergen penetration2. Immune factors, particularly Th2-mediated pathways, contribute to inflammation and hypersensitivity3.
2.2 Ayurvedic Perspective
In Ayurveda, eczema is seen as Vicharchika, a condition rooted in Pitta and Kapha imbalances with secondary Vata involvement. Factors like poor diet, stress, and seasonal changes exacerbate dosha imbalances, leading to blood impurities (Rakta Dushti) and skin inflammation4.
3. Clinical Features
Eczema typically presents as erythematous, itchy patches, often localized to the face, neck, and extremities in infants, while in adults, it appears more in flexural areas like the elbows and knees5. Secondary bacterial infections are common due to scratching6. Ayurvedic texts describe similar symptoms, noting the characteristic itching (kandu), erythema (rakta), and oozing (srava) associated with Vicharchika7.

4. Diagnosis
Diagnosis is clinical, based on characteristic symptoms and family history8. Patch testing can identify allergens, while blood tests may reveal elevated IgE levels, particularly in atopic dermatitis9. In Ayurveda, diagnosis also considers dosha imbalances, dietary history, and seasonal influences10.

5. Treatment Approaches
5.1 Modern Medical Treatments
5.1.1 Topical and Systemic Therapies
Topical Corticosteroids: These are first-line treatments for managing inflammation and itching11.
Topical Calcineurin Inhibitors: Tacrolimus and pimecrolimus reduce inflammation with minimal side effects12.
Moisturizers and Barrier Repair Creams: Emollients like ceramides help restore skin integrity13.
Systemic Immunosuppressants: In severe cases, cyclosporine or methotrexate may be used to control immune response14.
5.1.2 Biologics
Dupilumab: A monoclonal antibody that targets the IL-4 and IL-13 pathways, reducing inflammation in moderate-to-severe eczema15.
5.1.3 Phototherapy
UVB Therapy: Ultraviolet B therapy is beneficial for patients with widespread eczema, reducing symptoms and inflammation16.
5.2 Ayurvedic Treatments
5.2.1 Herbal Remedies
Neem (Azadirachta indica): Known for its antibacterial and anti-inflammatory properties, neem is used to cleanse and soothe skin17.
Manjishtha (Rubia cordifolia): This herb purifies the blood, helping to reduce skin inflammation and discoloration18.
Haridra (Curcuma longa): Curcumin in turmeric acts as an anti-inflammatory, reducing redness and itching19.
And other oral and external applications.
5.2.2 Panchakarma and Detoxification
Virechana: Therapeutic purgation aims to eliminate toxins, specifically targeting Pitta and Kapha imbalances20.
Raktamokshana: Bloodletting can relieve symptoms by purifying the blood, addressing the inflammatory components of eczema21.
And other oral and Detoximations Therapies.
5.2.3 Dietary and Lifestyle Modifications
Avoidance of Pitta-Aggravating Foods: Spicy, sour, and fried foods are restricted to reduce internal heat22.
Regular Abhyanga (Oil Massage): Using medicated oils like sesame or coconut oil can nourish and protect the skin from dryness23.
5.2.4 Mind-Body Practices
Yoga and Pranayama: Techniques such as Sheetali (cooling breath) and stress-relieving asanas help manage eczema triggers related to stress24.
6. Prevention
6.1 Modern Preventive Measures
Maintaining Skin Hydration: Regular application of emollients helps to maintain barrier function25.
Trigger Avoidance: Identifying and avoiding allergens or irritants reduces the risk of flare-ups26.
6.2 Ayurvedic Preventive Measures
Seasonal Regimens: Ayurveda emphasizes adjusting dietary and lifestyle practices according to seasonal changes to prevent dosha imbalances27.
Herbal Tonics: Herbs like Guduchi (Tinospora cordifolia) strengthen immunity, reducing susceptibility to inflammatory conditions28.
7. Discussion
The integration of modern and Ayurvedic perspectives offers a more comprehensive understanding of eczema. Modern approaches focus on controlling symptoms and restoring skin barrier function, while Ayurvedic treatments aim at addressing the root cause and balancing doshas. Evidence supporting Ayurvedic therapies, like herbal treatments and Panchakarma, indicates potential complementary benefits, particularly in reducing inflammation and enhancing skin health29.
8. Conclusion
Eczema requires a multifaceted approach due to its chronic and complex nature. Combining modern medical interventions with Ayurvedic therapies may provide more sustainable relief and improve patients' quality of life. Further research into Ayurvedic treatments could enhance integrative care for eczema, aligning with holistic patient care goals.
