Introduction
Non-healing wounds, also known as chronic wounds, fail to progress through normal stages of healing within a predictable time frame, typically persisting for more than four weeks. These wounds are often associated with systemic conditions such as diabetes mellitus, venous or arterial insufficiency, and infections, leading to significant morbidity and healthcare costs globally. In Ayurveda, ancient Indian system of medicine, management of such wounds is deeply rooted in principles of Vrana Chikitsa (wound care). This review aims to provide a comprehensive comparison of Ayurvedic & modern surgical approaches to chronic wound management & explore potential integrative strategies.
Ayurvedic Perspective on Non-Healing Wounds
1. Concept of Vrana (Wounds):
- Nija Vrana (Endogenous): Resulting from systemic imbalances, typically involving aggravated Doshas (Vata, Pitta, Kapha).
- Agantuja Vrana (Traumatic): Resulting from external injuries such as cuts, burns, or surgical interventions.
- Chronic Wounds as Dushta Vrana:
- These wounds are characterized by persistent infection, foul-smelling discharge, slough formation, and delayed healing.
- The pathogenesis involves impaired circulation, Dosha vitiation, and the presence of Ama (toxins).
2. Principles of Wound Management in Ayurveda:
- Removal of necrotic tissue, debris, and pus to prepare the wound bed.
- Use of herbal decoctions like Panchavalkala Kwatha for irrigation.
- Application of herbal oils, pastes, and powders to promote granulation and epithelialization.
- Srotoshodhana (Channel Cleansing):
- Ensures proper drainage of toxins and exudates, preventing wound stagnation.
3. Ayurvedic Interventions:
- Preparation: A medicated thread coated with alkaline herbal extracts such as Apamarga (Achyranthes aspera) and Snuhi (Euphorbia neriifolia) latex.
- Mechanism: Sustained chemical cauterization, antibacterial action, and stimulation of granulation tissue.
- Indications: Effective for sinus tracts, fistulas, pilonidal sinus, and non-healing ulcers.
- Jatyadi Taila: Contains herbs like Nimba (Azadirachta indica) and Haridra (Curcuma longa) for antimicrobial and anti-inflammatory effects.
- Madhu (Honey): A natural humectant with antibacterial and granulation-promoting properties.
- Haridra Churna (Turmeric Powder): Used for dusting wounds to reduce inflammation and prevent infection.
- Dasanga Lepa: A paste made from ten medicinal herbs, applied to reduce swelling and promote healing.
- Triphala Powder: Contains Haritaki, Bibhitaki, and Amalaki for antimicrobial action and cleansing.
4. Systemic Therapies:
- Rasayana (Rejuvenation): Medicines like Chyawanprash and Guduchi (Tinospora cordifolia) to boost immunity.
- Panchakarma (Detoxification): Procedures like Virechana (therapeutic purgation) to eliminate systemic toxins contributing to delayed healing.
Modern Surgical Approaches
1. Standard Wound Care Protocols:
- Surgical: Scalpel or scissors used to remove necrotic tissue.
- Enzymatic: Application of proteolytic enzymes to dissolve slough.
