Snake Poisoning (Sarpa Damsha) - Case Study in the Context of Ayurveda
An integrative case study grounded in classical Ayurvedic texts and corroborated by modern clinical findings
Epidemiological Context
India reports approximately 81,000 snakebite cases and 11,000 deaths annually, making it the country with the world's highest snake-bite mortality burden. The WHO has classified snakebite as a neglected tropical disease. India's four medically significant species (the "Big Four") are the Indian cobra (Naja naja), common krait (Bungarus caeruleus), Russell's viper (Daboia russelii), and saw-scaled viper (Echis carinatus). Most victims are agricultural laborers, plantation workers, or farmers bitten in rural settings where access to Anti-Snake Venom (ASV) is severely limited.
India sits in the highest mortality bracket globally (>3-6.6 deaths per 100,000) - Harrison's Principles of Internal Medicine, 22E
Case Presentation
Patient: Ramakant Patel, 42-year-old male farmer
Location: Rural village, Vidarbha region, Maharashtra
Date of Bite: June 2024, approximately 06:30 AM
Presenting to: District Ayurvedic hospital (nearest facility, 18 km away)
History of Present Illness
The patient was working in his paddy field at dawn when he felt a sharp piercing pain on his right ankle. He looked down and saw a medium-sized snake with a triangular head and distinct hourglass body markings escape into the bushes - consistent with a Russell's viper (Daboia russelii), classified in Ayurveda as belonging to the Mandali sarpa group (pit vipers / hemotoxic snakes described by Sushruta in Sarpachikitsa Adhyaya).
A family member first applied a tight cloth tourniquet around the calf and made incisions over the bite site with a blade and sucked out blood - traditional village first-aid measures.
The patient arrived at the Ayurvedic hospital 2 hours after the bite with the following complaints:
- Severe pain and rapidly progressive swelling of the right ankle and lower leg
- Burning sensation extending up to the knee
- Nausea, one episode of vomiting
- Mild gum bleeding noticed while rinsing mouth
- Anxiety and restlessness
Ayurvedic Classification of the Case
Agadatantra Framework
In Ayurveda, Agadatantra (toxicology) is one of the eight branches (Ashtanga Ayurveda). Snake venom is classified as Jangam Visha (poison of animal origin). The Ayurvedic term for a snake bite is Sarpa Damsha.
Acharya Sushruta (Sushruta Samhita, Kalpasthana) classified terrestrial snakes (Bhauma Sarpa) into five groups:
| Ayurvedic Group | Modern Equivalent | Dominant Dosha Vitiated | Predominant Symptoms |
|---|---|---|---|
| Darvikar (hood-spreading) | Cobra, Naja spp. | Vata + Kapha | Neurotoxic: drooping eyelids, paralysis |
| Mandali (circular-patterned) | Pit vipers, Russell's viper | Pitta | Hemotoxic: local necrosis, bleeding, edema |
| Rajiman (striped) | Kraits | Vata | Neurotoxic: painless, ascending paralysis |
| Nirvisha | Non-venomous snakes | - | Local injury only |
| Vaikaranja | Hybrid/unknown | All three doshas | Mixed presentation |
In this case: The hourglass pattern, triangular head, and predominantly hemotoxic features (severe local swelling, gum bleeding) firmly place this as Mandali Sarpa Damsha - a Pitta-predominant envenomation.
Vega (Stages of Envenomation)
Classical texts describe progression of snake venom toxicity through Vegas (stages). By the time of arrival, the patient was in the 3rd Vega (Tritiya Vega):
| Vega | Features |
|---|---|
| 1st (Prathama) | Local pain, erythema, mild swelling |
| 2nd (Dvitiya) | Increased swelling, burning, nausea/vomiting |
| 3rd (Tritiya) | Spreading edema past the knee, hemorrhagic signs, systemic involvement |
| 4th (Chaturtha) | Shock, oliguria, multi-organ dysfunction |
Examination Findings
| Parameter | Finding |
|---|---|
| Pulse (Nadi) | Rapid (104/min), weak - Vata-Pitta predominance confirmed |
| Blood Pressure | 90/60 mmHg (hypotensive) |
| Temperature | 37.8°C |
| Bite site | Two puncture marks 1.5 cm apart on right lateral ankle |
| Swelling | Extending from ankle to mid-thigh |
| Skin | Ecchymosis, blistering around bite site |
| Eyes | Mild ptosis absent (no neurotoxic signs) |
| Gum bleeding | Present |
| Urine output | Reduced, dark amber |
Laboratory:
- Clotting time: >20 minutes (normal <6 min) - coagulopathy confirmed
- Haematuria on urine dipstick: positive
- Hemoglobin: 9.8 g/dL (falling)
Ayurvedic Diagnosis
Sarpa Damsha - Mandali Jati - Tritiya Vega
(Russell's viper envenomation, Pitta-predominant, Stage 3)
Ayurveda describes the pathology as follows: Russell's viper venom causes Raktavaha Srotas Dushti (vitiation of blood-carrying channels), leading to:
- Rakta Vikara (blood dyscrasia / hemorrhage) - corresponds to venom-induced consumption coagulopathy (VICC)
- Mansa Kshaya (tissue destruction / necrosis)
- Mutravaha Srotas Dushti (renal damage) - corresponds to acute tubular necrosis from hemolysis and hypotension
Treatment Protocol: Chaturvimsati Vishachikitsa Upakrama
Acharya Charaka (Charaka Samhita, Chikitsa Sthana, Chapter 23) described 24 therapeutic procedures (Upakramas) for managing Vishachikitsa. The classical sequence applied in this case:
Immediate (Tatkala) Measures Applied
1. Arishta Bandhanam (Ligature)
A correctly placed bandage proximal to the bite (not a tight tourniquet) to slow lymphatic spread. The tight cloth tourniquet applied in the field was immediately loosened to prevent ischemia. Note: This is one area where Ayurvedic classical advice aligns with modern first aid - the WHO also recommends pressure immobilization only.
2. Utkartanam (Incision)
Shallow cruciate incision over the bite marks, applied only because the bite was on a non-vital site (lateral ankle, away from tendons and vessels). Sushruta warns against incision over vital points (Marma).
3. Nishpeedanam (Expression / Compression)
Gentle expression of blood from the incision site.
4. Achushanam (Suction)
Mechanical suction using a cupping device (not by mouth, as classical texts specify the practitioner must have no mouth ulcers; modern guidelines now discourage this entirely due to infection risk).
5. Agni (Cauterization)
Thermal cauterization of the bite wound was not performed in this case as it was already past 2 hours and Pitta-predominant bites carry risk of worsening tissue damage. Modern emergency medicine also contraindicates this.
6. Parisheka / Avagaham (Irrigation / Immersion)
Wound was thoroughly irrigated with a decoction of Panchavalkala Kashaya (five-bark decoction: Vata, Ashwattha, Udumbara, Parisha, Plaksha) for its antimicrobial and anti-inflammatory (Vrana Shodhana) properties.
7. Pratisaranam (Topical application of antidote powder)
A paste of Haridra (Curcuma longa), Saindhava Lavana (rock salt), Pippali, and Maricha was applied to the incised wound. Haridra's anti-inflammatory and antibacterial properties are well-documented in modern research.
8. Vamana Karma (Therapeutic Emesis)
Since the bite was below the umbilicus, Charaka advises Virechana (purgation) rather than Vamana. Vamana is recommended when the bite is above the umbilicus to expel venom through the upper GI route.
9. Virechana (Therapeutic Purgation)
Trivrit churna (Operculina turpethum) administered orally in mild dose to assist downward expulsion of visha.
10. Hridayavarana (Protection of the Heart)
This was given highest priority. Charaka's instruction to "protect the heart first" corresponds to the modern priority of preventing cardiovascular collapse. Administered:
- Sarpagandha (Rauvolfia serpentina) - for cardiovascular stabilization
- Arjuna tvak kashaya (Terminalia arjuna bark decoction) - cardiac tonic
- Vasa (Adhatoda vasica) - for respiratory and cardiac support
Core Ayurvedic Oral Formulations Used
| Formulation | Classical Reference | Modern Pharmacological Basis |
|---|---|---|
| Sarpavishadi Vati | Ashtanga Hridayam | Contains Tankana (borax), Haridra - anti-inflammatory, chelating |
| Mahamanjishtadi Kashaya | Sahasrayoga | Manjishtha (Rubia cordifolia) - anti-inflammatory, blood purifier |
| Gandhaka Rasayana | Charaka Samhita | Purified sulfur compound - wound healing, antimicrobial |
| Shirisha (Albizia lebbeck) bark decoction | Charaka Samhita (Vishaghna drugs) | Anti-venom properties scientifically validated; contains saponins and flavonoids |
| Khadirarishta | Bhaishajya Ratnavali | Acacia catechu - antimicrobial, wound healing |
Shirisha (Albizia lebbeck) holds special importance: it is listed by Charaka as the foremost Vishaghna (anti-poison) drug and its bark extract has shown neutralization of Russell's viper venom phospholipase A2 activity in experimental studies.
Critical Clinical Decision: Integration with Modern Medicine
This is the most important and realistic aspect of the case.
On arrival, the Ayurvedic physician recognized the following red flags:
- Active coagulopathy (clotting time >20 min)
- Hematuria
- Hypotension (BP 90/60)
- Grade 3 envenomation by WHO criteria
Decision taken: Immediate referral for IV Polyvalent Anti-Snake Venom (PAV) while initiating Ayurvedic supportive therapy concurrently.
The Ayurvedic physician arranged IV access, administered IV fluids (Ringer's Lactate), and called for PAV transfer. The patient received 10 vials of PAV (each neutralizing ~6-8 mg venom, prepared against the Big Four; available from Haffkine Institute, Mumbai) infused over 1 hour - as per the Essentials of Forensic Medicine and Toxicology (36th ed., 2026). A second dose of 10 vials was given at 1 hour as per protocol for hemotoxic envenomation.
"In neurotoxic poisoning, a second dose of ten vials should be given after one hour. In hemotoxic patients the initial dose of antiserum will be neutralizing unbound venom." - Essentials of Forensic Medicine and Toxicology, 36th Edition
This integrative decision - using Ayurvedic therapy for wound management and systemic support, with modern ASV for neutralizing circulating venom - reflects responsible contemporary practice.
Post-Acute Ayurvedic Management (4-Month Follow-up)
After discharge on day 7, the patient developed a chronic non-healing ulcer (3x4 cm) at the bite site - a known complication of Russell's viper bites due to local tissue necrosis from phospholipase A2, hyaluronidase, and cytotoxic fractions in the venom.
This complication is described in Ayurveda as Dushta Vrana (chronic infected wound), categorized as Krichhra Sadhya (difficult to cure). Modern medicine had little to offer beyond standard wound care; Ayurvedic wound management was continued.
Sapta Upakrama (Seven Wound Management Procedures) Applied:
| Procedure | Description |
|---|---|
| Vrana Prakshalana | Washing with Panchavalkala kashaya decoction (five barks) |
| Pariseka | Irrigation of wound with medicated decoctions twice daily |
| Lepana | Application of paste - Jatyadi taila (oil containing Jati/Jasminum, Nimba, Haridra, Madhuka) |
| Bandha | Medicated bandaging with Jatyadi taila-soaked gauze |
| Ropana Dravyas | Wound-healing agents: Madhuka, Manjishtha, Lodhra applied topically |
Oral Treatment Schedule (4 Months):
Month 1 (hospital admission):
- Panchavalkala kashaya parisheka (irrigation)
- Bandha with Jatyadi taila
- Oral: Gandhaka Rasayana 1 tsp BD, Mahamanjishtadi Kashaya 30 mL BD
Months 2-4 (outpatient):
- Continued Jatyadi taila bandaging, wound irrigation every 15 days at hospital
- Oral: Gandhaka Rasayana + Triphala Churna (bowel regulation, antioxidant)
- Result: Complete wound closure by end of month 4, with no recurrence
A published PMC case report (PMID: 41076971) documents this identical treatment protocol for post-viper-bite chronic ulcers and confirms complete healing with the same regimen.
Dosha Analysis Throughout the Case
| Phase | Dosha Status | Clinical Correlate |
|---|---|---|
| Acute (day 1) | Pitta > Vata | Burning, necrosis, hemorrhage, fever |
| Subacute (days 2-7) | Pitta + Kapha | Edema, purulent discharge, slough |
| Chronic (weeks 2-16) | Vata + Kapha | Non-healing wound, cold induration |
| Healed state | Tridosha balanced | Clean granulation, re-epithelialization |
Ayurvedic-Modern Comparison of First Aid Measures
| Classical Ayurvedic Upakrama | Modern First Aid Comparison | Current Status |
|---|---|---|
| Arishta Bandhanam (pressure bandage) | Pressure immobilization bandage (WHO) | Partially valid - tight tourniquet contraindicated |
| Utkartanam (incision) | Not recommended (WHO, 2024) | Discarded in modern guidelines |
| Achushanam (suction) | Contraindicated (WHO) | Discarded |
| Parisheka (irrigation) | Wound washing with soap and water recommended | Valid and aligned |
| Vamana / Virechana | Not applicable in modern management | Historical only |
| Hridayavarana (cardiac protection) | Supportive care for cardiovascular collapse | Conceptually aligned |
| Shirisha / vishaghna herbs | Under research (some evidence for Albizia, Withania) | Adjunctive role being studied |
Key Ayurvedic Drugs with Scientific Validation
- Haridra (Curcuma longa): Curcumin inhibits PLA2 activity, reduces edema in viper envenomation (animal studies)
- Shirisha (Albizia lebbeck): Bark extract demonstrated significant neutralization of Russell's viper venom-induced hemorrhage in experimental models
- Sarpagandha (Rauvolfia serpentina): Reserpine content; useful for venom-induced hypertensive crises (though hypotension is more common)
- Manjishtha (Rubia cordifolia): Anti-inflammatory, improves microcirculation, promotes wound healing
- Gandhaka (purified sulfur): Broad-spectrum antimicrobial action relevant to preventing wound superinfection
Clinical Pearls: What Ayurveda Gets Right
- Prioritizing Hridaya (cardiac protection) - Ayurveda's fundamental instruction to protect the heart in snake bite precisely anticipates modern priorities in managing hemodynamic collapse.
- Wound management with medicated oils and bark decoctions - Jatyadi taila and Panchavalkala kashaya have documented wound-healing, antimicrobial, and anti-inflammatory properties that modern wound care lacks equivalent for in the post-ASV chronic phase.
- Vishaghna diet and lifestyle - Charaka advises light, easily digestible food (Laghu Ahara), avoidance of alcohol, and rest - all consistent with supportive care principles.
- Recognizing stages (Vegas) - The concept of sequential progression of envenomation mirroring modern grading systems reflects genuine empirical observation across centuries.
Critical Limitations of Exclusive Ayurvedic Management
- Anti-Snake Venom remains the only life-saving intervention for severe envenomation. No herbal preparation can neutralize circulating venom with the speed, specificity, and potency of PAV. Relying on Ayurveda alone for grade 3-4 envenomation is dangerous and has contributed to preventable deaths.
- The WHO-endorsed snakebite management guidelines explicitly state that all traditional incision, suction, tourniquet, and herbal paste methods at the bite site are either ineffective or harmful when substituted for ASV.
- Ayurveda's greatest validated role is in post-envenomation wound care and rehabilitation - an area where modern medicine often has inadequate tools, particularly for chronic necrotic ulcers.

Bottom line: This case illustrates that Ayurveda offers a thoughtful, systematized approach to snake envenomation developed over millennia. Its real-world strength in contemporary practice lies in chronic wound management, supportive care, and adjunctive anti-inflammatory therapy - not as a replacement for Anti-Snake Venom, which remains the irreplaceable cornerstone of acute envenomation treatment. The most effective approach, as demonstrated in this case, is integrative: timely ASV for acute venom neutralization + Ayurvedic protocols for wound healing and rehabilitation.
