Review of Literature: Development of 2% Kshara Ointment for Dushta Vrana
Department of Shalya Tantra - PG Scholar Dissertation Review
1. INTRODUCTION
Vrana (wound/ulcer) and its management form the cornerstone of Shalya Tantra (Ayurvedic Surgery). Acharya Sushruta, the "Father of Surgery," devoted extensive attention to wound classification and management in the Sushruta Samhita. When a wound fails to heal within the expected time, or when it is invaded by vitiated Doshas causing characteristic features of purulence, discoloration, and delayed healing, it is termed Dushta Vrana - the infected or chronic non-healing wound.
Kshara, described as a caustic alkaline substance derived from the calcined ashes of medicinal plants, occupies a supreme place among Ayurvedic para-surgical procedures. The present research aims to develop a 2% Kshara Ointment (Kshara Malahara) as a novel topical formulation for the management of Dushta Vrana - combining classical Ayurvedic therapeutic principles with modern pharmaceutical technology.
2. REVIEW OF LITERATURE
2.1 Conceptual Review of Dushta Vrana
2.1.1 Definition and Etymology
The word Vrana is derived from the Sanskrit root Vrana meaning a wound or ulcer - defined by Acharya Sushruta as destruction or discontinuity in body tissues (Shareerasya vrana iti uktam - Sushruta Samhita, Sutrasthana). A Dushta Vrana is one in which the three Doshas (Vata, Pitta, Kapha) localize and cause vitiation (dushana), rendering the wound difficult to heal. It corresponds closely to the modern concept of a chronic non-healing wound or infected wound.
2.1.2 Classical Features (Lakshana) of Dushta Vrana
According to Sushruta Samhita Chikitsa Sthana, Dushta Vrana is characterized by:
- Durgandha - foul odour
- Bahusrava - copious discharge
- Vivarna - abnormal discolouration (blackish, pale or ashy)
- Katina sparsha - hardened wound edges
- Kandu - pruritus/itching
- Atishoola - excessive pain
- Atiraaga - excessive redness
- Chirokthita - prolonged duration without healing
2.1.3 Types of Dushta Vrana (Dosha-wise)
- Vataja Dushta Vrana: Severe pain, blackish colour, highly contracted (Athisanvrita), hardened edges (Atikatina), and deeply seated (Avasanna)
- Pittaja Dushta Vrana: Burning sensation, excessive redness, yellowish-green discharge
- Kaphaja Dushta Vrana: Itching, pale or white colour, cold to touch, excessive slimy discharge
- Sannipataja Dushta Vrana: Combined features; most difficult to treat
2.1.4 Modern Correlation
Dushta Vrana correlates with:
- Chronic non-healing wounds (non-healing beyond 6-8 weeks)
- Infected surgical wounds
- Diabetic foot ulcers
- Venous leg ulcers
- Pressure ulcers
- Traumatic infected wounds
Modern wound healing involves four phases: Hemostasis, Inflammation, Proliferation, and Remodeling. In Dushta Vrana, there is pathological arrest primarily at the inflammatory phase due to persistent microbial load, necrotic tissue, and biofilm formation.
2.2 Shashti Upakrama (60 Treatment Measures for Wounds)
Acharya Sushruta enumerates Shashti Upakrama - 60 treatment measures for wounds in Sushruta Samhita Chikitsa Sthana. Among these, the relevant measures for Dushta Vrana include:
| Upakrama | Procedure | Modern Correlate |
|---|
| Shodhana | Wound cleansing/debridement | Wound bed preparation |
| Ropana | Wound healing | Tissue regeneration |
| Lekhana | Scraping of unhealthy tissue | Mechanical debridement |
| Vrana Dhoopana | Fumigation of wound | Antiseptic fumigation |
| Pichu Dharana | Application of medicated gauze/wick | Wound packing |
| Vrana Bandhana | Wound dressing/bandaging | Modern dressing |
Kshara Karma achieves multiple upakramas simultaneously - performing Shodhana, Lekhana, Ropana, and Krimighna (antimicrobial) actions in one application.
2.3 Kshara - Classical Overview
2.3.1 Definition
Acharya Sushruta defines Kshara in Sutrasthana as a substance possessing Ksharana (corrosive/erosive action) and Kshapana (destroying/eliminating) properties. It is described as a "Biosalt" - an alkaline compound derived from plant ash. Kshara is categorized under Anushastra (accessory surgical instruments), and is described as superior to all other surgical instruments because of its capacity to simultaneously cut, scrape, cleanse, and heal.
"Kshara iti Sarva Shastra Anuttamam" - Kshara is the best among all surgical instruments (Sushruta Samhita, Sutrasthana 11)
2.3.2 Classification
A. Based on mode of administration:
- Pratisaraneeya Kshara (topical/external use) - applied directly on the lesion
- Paneeya Kshara (internal use) - taken orally in calculated doses
B. Based on potency (Tikshnatva):
- Mridu Kshara (mild/gentle) - used for delicate areas and mild lesions
- Madhyama Kshara (moderate) - used for moderately severe lesions
- Tikshna Kshara (sharp/potent) - used for severe, deep, chronic lesions
2.3.3 Ideal Properties (Guna) of Kshara
According to Sushruta Samhita Sutrasthana Chapter 11, an ideal Kshara should possess the following qualities:
- Na Atitikshna - not excessively sharp
- Na Atimrudu - not excessively mild
- Na Atishukla - not excessively white
- Shlakshna - smooth to touch
- Pichhila - slimy
- Avishyandi - non-spreading/non-flowing
- Shiva - neither too hard nor too soft in action
- Shighra - rapid in action
- Shikhari - stable when placed in a heap
- Sukhanirvapya - easy to neutralize
2.3.4 Therapeutic Properties of Kshara
- Chhedana - excision/cutting
- Bhedana - incision/bursting
- Lekhana - scraping of unhealthy tissue
- Dahana - chemical cauterization
- Pachana - digestion of necrotic matter
- Vilayana - dissolution/liquefaction of slough
- Darana - bursting/rupture of accumulated pus
- Vrana Shodhana - wound cleansing
- Vrana Ropana - wound healing
- Kled Shoshana - absorption of excessive wound moisture
- Krimighna - antimicrobial action
- Tridoshaghna - normalizes all three vitiated Doshas
2.3.5 General Scientific Properties
- Alkaline nature (high pH) - creates an unfavorable environment for pathogens
- Antacid action
- Diuretic property (internally)
- Depurative (purifying) action
- Chemical debridement - saponins, flavonoids, and alkaloids dissolve necrotic tissue
2.4 Kshara Kalpana - Dosage Forms
Various Kshara formulations have been described in classical texts and modern Ayurvedic practice:
2.4.1 Pratisaraneeya Kshara (Topical Kshara)
The most commonly used form for wound management. It is applied directly to the lesion using a probe or spatula. Examples include:
- Apamarga Pratisaraneeya Kshara (Achyranthes aspera) - most widely studied
- Palasha Pratisaraneeya Kshara (Butea monosperma)
- Mulaka Kshara (Raphanus sativus)
- Chitraka Kshara (Plumbago zeylanica)
2.4.2 Ksharasutra
A medicated surgical thread coated with Snuhi Ksheera (latex of Euphorbia nerrifolia), Apamarga Kshara, and Haridra (Curcuma longa). Standard preparation involves 21 coatings: 11 of Snuhi alone, 7 of Snuhi + Apamarga Kshara, and 3 of Snuhi + Haridra. Widely used in Bhagandara (fistula-in-ano) and Nadivrana (sinus tracts).
2.4.3 Kshara Pichu
Medicated gauze/wick coated with Kshara, used for wound packing and sustained release of the alkaline agent into the wound bed. Effective in deep Dushta Vrana with sinus formation.
2.4.4 Ksharaplota
A gauze piece coated with Snuhi Ksheera and Kshara, applied over infected wounds. Shekokar and Ukhalkar (IJAM) demonstrated its efficacy in infected wounds, showing significant reduction in pain, discharge, and wound size.
2.4.5 Kshara Taila (Kshara Oil)
Kshara processed with Tila Taila (sesame oil) and other ingredients. Gopika and Rajeshwari (2025, PMID: 40651265) demonstrated the effect of Apamarga Kshara Taila on diabetic pressure ulcers with significant improvement in wound parameters. This represents a stable, lipid-based Kshara formulation analogous to an ointment base.
2.4.6 Kshara Malahara/Ointment (Proposed Novel Form)
A semi-solid topical preparation incorporating Kshara at a controlled concentration (2%) in a suitable ointment base. This novel formulation bridges classical Kshara Karma with modern pharmaceutical technology, providing:
- Controlled and sustained delivery of alkaline active
- Ease of application without skilled practitioner requirement
- Standardized concentration (2%) for consistent therapeutic effect
- Improved shelf life and patient compliance
2.5 Source Plants for Kshara Preparation

2.5.3 Snuhi (Euphorbia nerrifolia Linn.)
- Used as a Prakshepaka Dravya (adjuvant) to enhance Tikshnatva of Kshara
- Contains latex with Tikshna, Ushna, and Krimighna properties
2.6 Pharmaceutical Standardization of Kshara
Jadav, Galib, and Prajapati (2015, PMID: 26834430) established the Standard Manufacturing Process (SMP) for Apamarga Kshara, which is the foundational reference for any Kshara-based formulation:
Preparation Method:
- Apamarga Panchanga (whole plant) collected, dried, and cut into small pieces
- Burned completely to produce ash (Bhasma)
- Ash dissolved in water (ratio 1:6) and left undisturbed overnight
- Supernatant filtered through 4-layered clean cloth (21 times traditionally; Sushruta Samhita specifies cloth folding methodology)
- Filtrate heated to evaporate water content - yielding solid Kshara
- Three successive washes yield: 21.23%, 9.38%, and 4.76% Kshara respectively
Physicochemical Parameters established:
| Parameter | APK1 | APK2 | APK3 |
|---|
| pH | 10.61 | 11.12 | 10.72 |
| Total Ash (%) | - | - | - |
| Loss on drying (110°C) | Determined | Determined | Determined |
| Acid insoluble ash | Determined | Determined | Determined |
| Water soluble extractives | Determined | Determined | Determined |
Shrestha, Harisha, and Dudhamal (2018, PMID: 31000993) conducted comparative pharmacognostical analysis of Mridu and Tikshna Apamarga Kshara, establishing microscopic and physicochemical differences between the two grades - important for selecting appropriate potency for 2% ointment formulation.
2.7 Mechanism of Action in Wound Healing
2.7.1 Ayurvedic Mechanism
Kshara acts through the following sequence in Dushta Vrana management:
- Dahana/Vilayana: Chemical cauterization dissolves and liquefies necrotic slough
- Lekhana: Scraping action removes devitalized and unhealthy granulation tissue
- Kled Shoshana: Hygroscopic nature absorbs excessive wound exudate and reduces edema of granulation tissue
- Krimighna: Alkaline pH inhibits pathogen growth; antimicrobial phytoconstituents reduce microbial load
- Shodhana: Complete wound debridement creates clean wound bed
- Ropana: After Shodhana, promotes healthy granulation tissue formation, enhances vascularity, and accelerates re-epithelialization
Once the slough is removed, further application of Kshara should be stopped as it can damage healthy granulation tissue - a critical clinical guideline.
2.7.2 Modern Mechanism
- Chemical debridement: High alkaline pH (10.6-11.1) denatures proteins in necrotic tissue, facilitating autolytic and enzymatic debridement
- Antimicrobial action: High pH environment inhibits the growth of gram-positive and gram-negative organisms and fungi; flavonoids and saponins (Achyranthine) provide additional antimicrobial activity
- Anti-biofilm effect: Alkaline pH disrupts bacterial biofilm matrix - the primary reason for wound chronicity
- Hygroscopic effect: Reduces wound edema, decreasing interstitial fluid pressure and improving microvascular perfusion
- Angiogenesis promotion: Once debridement is complete, removal of growth-inhibiting factors (MMPs, necrotic debris) promotes VEGF-mediated neovascularization
- Re-epithelialization: Clean wound bed with appropriate moisture balance facilitates keratinocyte migration
2.8 Clinical Studies on Kshara in Dushta Vrana
2.8.1 Kshara Karma (Direct Application)
Asma et al. (IJBPAS, 2022) - "Kshara Karma in the Management of Dushtavrana (Chronic Non-healing Wound)": Case report using
Palasha Pratisaraneeya Kshara in a chronic wound. Internal medications included Kaishora Guggulu and Manjishtadi Kashaya. The wound achieved complete healing in 3 months with improvement in quality of life. Conclusion: Kshara Karma provides effective debridement enabling the wound to progress through the healing cascade. (

2.8.2 Comparative Study - Kshara Lepa vs. Jaloukavacharana
A comparative study of Apamarga Kshara Lepa and Jaloukavacharana (JAIMS) - Randomized clinical trial (n=40) with 20 subjects in each group:
- Group A: Apamarga Pratisaraneeya Kshara Lepa (with Vacha and Chitraka as Prakshepaka Dravyas)
- Group B: Jaloukavacharana (leech therapy)
Results showed both groups achieved significant reduction in pain, burning sensation, discharge, and itching. Group A mean pain score reduced from 3.15 to 1.00; Group B from 3.10 to 0.80. The Tridoshaghna, Vilayana, and Krimighna properties of Kshara explained its therapeutic action. Both modalities were found effective, with leech therapy showing slight advantage in burning sensation (due to Sheeta Guna of leech saliva).
2.8.3 Ksharaplota in Dushta Vrana
Shekokar and Ukhalkar (IJAM) - "Study of Efficacy of Ksharaplota in Dushtavrana w.s.r to Infected Wound" - PhD scholars from Department of Shalyatantra, Govt. Ayurved College, Nanded. Ksharaplota (gauze coated with Snuhi Ksheera and Kshara) was applied over infected wounds. Significant improvement was noted in all wound parameters.
2.8.4 Apamarga Kshara Taila in Diabetic Pressure Ulcer
Gopika G and Rajeshwari PN (2025, PMID: 40651265) - "Effects of Apamarga Kshara Taila on diabetic pressure ulcer" - Case report demonstrating that a lipid-based Kshara formulation (oil/taila) effectively managed diabetic pressure ulcers with Vata-Kaphaja features, supporting the concept of using Kshara in a semi-solid base (ointment) for improved contact time and penetration.
2.8.5 Honey (Madhu) in Dushta Vrana
Dudhamal, Gupta, and Bhuyan (2010, PMID: 21455457) - "Role of honey (Madhu) in the management of wounds (Dushta Vrana)" - Established the classical basis for using natural wound-healing agents. Madhu is frequently combined with Kshara as an ointment base due to its Kashaya, Madhura Rasa, hygroscopic properties, and established antimicrobial activity - supporting the choice of honey-beeswax as an ointment base for Kshara ointment.
2.8.6 Systematic Review - Ayurveda Wound Healing Formulations
Dudhamal TS et al. (2023, PMC10424143) - "Review of grey literature on Ayurveda wound healing formulations and procedures" - A systematic review of 273 studies. Key findings:
- Kshara (plant alkalies) was used in 8 research studies on wound healing
- Malahara (medicated ointments) were used in 9 research studies
- Povidone iodine ointment was the most common control group (37 studies)
- Kshara provides chemical debridement in non-viable tissue cases
- Integrated approach with Kshara debridement saves diabetic limbs from amputation
2.9 Ointment Technology (Malahara Kalpana)
2.9.1 Classical Ointment Bases
- Ghrita (ghee) based: Jatyadi Ghrita, Triphala Ghrita
- Taila (oil) based: Kshara Taila
- Malahar (cream/ointment): Described in Ashtanga Hridayam and modern Ayurvedic practice
2.9.2 Modern Pharmaceutical Considerations for 2% Kshara Ointment
For development of 2% Kshara ointment, the following formulation parameters require investigation:
A. Ointment base selection:
- Hydrophilic base (water-soluble) - for easy application and wash-off
- Emulsion base (cream type) - for better skin penetration
- Petrolatum/soft paraffin base - for occlusive effect
- Natural base (beeswax + coconut oil) - aligned with Ayurvedic philosophy
B. Critical formulation challenges:
- Maintaining Kshara stability at 2% concentration without pH alteration of the base
- Preventing phase separation over shelf life
- Ensuring adequate rheology for wound application (consistency, spreadability)
- Compatibility of Kshara (high pH 10-11) with the chosen ointment base
- Buffering capacity and its effect on wound pH
C. Standardization parameters (proposed):
- Physical: Appearance, color, odor, consistency, pH, spreadability
- Chemical: Ash value, total alkalinity, water-soluble extractives
- Microbiological: Sterility/microbial load limits (as per IP/USP)
- Stability: Accelerated stability at 40°C/75% RH (6 months)
2.9.3 Rationale for 2% Concentration
- Excessive concentration (Atitikshna) damages healthy granulation tissue
- Sub-therapeutic concentration fails to achieve adequate debridement
- 2% represents the Mridu-Madhyama range, appropriate for Dushta Vrana without causing additional tissue damage
- Comparable to established topical agents: 2% Mupirocin ointment (antimicrobial), 2% Nitrofurazone (topical antimicrobial for wounds)
2.10 Related Studies and Drug Reviews
2.10.1 Terminalia Arjuna in Chronic Venous Insufficiency
Pratap Shankar and Ashwathykutty (2024, PMID: 38555178) - Demonstrated the effectiveness of herbal drugs in chronic wound conditions related to venous disease, reinforcing the evidence base for herbal topical preparations.
2.10.2 Katupila (Securinega leucopyrus) in Dushta Vrana
Ajmeer, Dudhamal, and Gupta (2014, PMID: 25558163) - "Topical application of Katupila in Dushta Vrana showing excellent healing effect" - Established that concentrated topical herbal applications on chronic wounds can achieve excellent healing outcomes, supporting the topical ointment concept.
2.10.3 Neem Oil and Haridra in Non-Healing Wounds
Singh, Singh, and Narayan (2014, PMID: 26195902) - Demonstrated efficacy of Neem oil and Haridra (turmeric) in non-healing wounds. Haridra (Curcuma longa) is frequently used as a Prakshepaka Dravya in Kshara formulations and may be incorporated as an adjuvant in the 2% ointment.
2.11 Wound Healing - Modern Perspective
Chronic wound healing involves well-characterized biology relevant to the proposed study:
- Wound Bed Preparation (WBP) - The TIME framework (Tissue, Infection/Inflammation, Moisture, Edge of wound) aligns with Ayurvedic Vrana Shodhana-Ropana principles
- Debridement - Chemical/enzymatic debridement (Kshara's Vilayana and Lekhana) removes slough enabling healing
- Biofilm management - Alkaline pH disrupts bacterial biofilm (primary cause of wound chronicity)
- Moist wound healing - Kshara's hygroscopic and Kled-Shoshana properties optimize wound moisture balance
- Angiogenesis and re-epithelialization - Post-debridement, Kshara's Ropana properties facilitate tissue regeneration

4. RESEARCH JUSTIFICATION (LACUNAE IN EXISTING KNOWLEDGE)
Based on the review of classical literature and contemporary research, the following gaps justify the present study:
- No standardized ointment formulation of Kshara exists with defined concentration (2%), despite Kshara Lepa, Kshara Pichu, and Kshara Taila being well-described
- Classical Kshara application requires skilled practitioner involvement and carries risk of excessive caustic action - a controlled 2% ointment addresses both limitations
- While Kshara Taila (oil base) has shown efficacy in diabetic ulcers (Gopika et al., 2025), no ointment-base formulation has been studied for Dushta Vrana
- Most existing studies are case reports (evidence tier 8) - a clinical trial using a standardized 2% Kshara ointment will provide higher-quality evidence
- Modern wound management relies on pH-controlled dressings - Kshara's established alkaline pH makes it an ideal candidate for a standardized wound ointment
- The WHO-aligned WBP (Wound Bed Preparation) framework can be applied to validate Kshara's mechanism in controlled clinical settings
