॥ प्रस्तावना ॥ (Introduction)

In Rasa Śāstra (the science of alchemy and iatrochemistry), Parada (Mercury) holds the supreme position. It is hailed as Mahārasa (the great entity) and is the pivotal dravya for all Rasāyana (rejuvenation) and Rasaushadhi (mercurial medicine) preparations. However, its improper use without the mandatory Śodhana (purification) and Māraṇa (incineration/processing) leads to severe toxic conditions known as Pārada Doṣa or Pārada Vikāra. The science of diagnosing and treating these conditions is Pārada Vikāra Chikitsā.

॥ निदानम् ॥ (Etiological Factors – Nidāna)

The causes of Pārada Vikāra are primarily due to the transgression of the principles of Rasa Śāstra.

1. Aśuddha Pārada Sevana: Consumption of mercury that has not undergone the prescribed Śodhana (purification) process.
2. Apakva Pārada Sevana: Ingestion of mercury that has not been properly processed through Māraṇa (e.g., improper Kajjali or other formulations).
3. Amātra Sevana: Administration in incorrect dosage (either too high or for an prolonged period without assessment).
4. Avicārita Sevana: Use without considering the patient’s Prakṛti (constitution), Sāra (tissue quality), Sattva (mental strength), and Vaya (age).
5. Apathya Sevana: Concurrent intake of incompatible diet and lifestyle (Viruddha Āhāra) while undergoing mercurial therapy. Key incompatible factors include:
   · Amla (sour substances), Lavana (excess salt)
   · Kṣāra (alkaline substances)
   · Madya (alcohol)
   · Atiśrama (excessive exertion)
   · Ātapa Sevana (excessive exposure to sunlight)

॥ संप्राप्ति ॥ (Pathogenesis – Samprapti)

The pathogenesis of Pārada Vikāra can be understood as follows:

1. Āma Doṣa Utpatti: The unprocessed, toxic mercury acts as a potent Āma (toxic metabolic residue) in the body.
2. Srotas Avarodha: This Āma circulates through the Rasa and Rakta Dhātu (plasma and blood tissues), causing micro-channels (Srotas) obstruction.
3. Tridoṣa Prakopa: It primarily vitiates Vāta Doṣa due to its Rūkṣa (dry) and Sūkṣma (subtle) guṇa. Subsequently, it disrupts Pitta (causing inflammation, burning sensation) and Kapha (causing salivation, heaviness).
4. Dhātu Kṣaya: The persistent vitiation leads to deterioration of the seven Dhātus (tissues), especially Rasa, Rakta, Māṃsa, and Asthi, manifesting a wide range of systemic symptoms.

॥ लक्षणानि ॥ (Clinical Features – Lakṣaṇa)

The symptoms manifest based on the predominant Doṣa involved and the Dhātu affected.

Doṣa Predominance Key Clinical Features (Lakṣaṇa)
Vāta Pradhāna Kampa (tremors), Śūla (colicky pain), Aṅgamarda (body ache), Sandhiśūla (arthralgia), Vāk Saṅga (slurred speech), Stambha (stiffness).
Pitta Pradhāna Dāha (burning sensation throughout the body), Tṛṣṇā (excessive thirst), Sweda (profuse sweating), Mukha Pāka (stomatitis), Raktapitta (bleeding disorders).
Kapha Pradhāna Chardi (vomiting), Aruci (anorexia), Praseka (excessive salivation), Gaurava (heaviness), Ālasya (lethargy), Śvāsa (dyspnea).
Sādhāraṇa Lakṣaṇa Sīdana (lassitude), Jvara (fever), Dantaharsa (dental hypersensitivity), Mukha Vairasya (bad taste in mouth), Keshpatana (hair fall).

॥ चिकित्सा सिद्धान्तः ॥ (Principles of Management – Chikitsā Siddhānta)

The treatment is based on the core Ayurvedic principles of Śodhana (purification/bio-cleansing) and Śamana (palliation).

1. Nidāna Parivarjana: Immediate cessation of the causative mercurial preparation and incompatible diet is paramount.
2. Āpacāra Kṣamāpana: Administration of specific antidotes to neutralize the mercury toxicity.
3. Śodhana Chikitsā (Panchakarma): This is the cornerstone of treatment.
   · Vamana (Therapeutic Emesis): To eliminate Kapha and Pitta dominant toxins from the upper GIT.
   · Virecana (Therapeutic Purgation): Crucial for eliminating Pitta and Vāta dominant toxins from the lower GIT. Often the primary procedure.
   · Basti (Medicated Enema): Especially Nirūha Basti (decoction enema) is vital to pacify the severely aggravated Vāta Doṣa.
   · Raktamokṣaṇa (Bloodletting): Indicated in severe Pitta and Rakta Dushti conditions to remove toxic blood.
4. Śamana Chikitsā (Palliative Therapy): Use of specific herbs and formulations to pacify Doṣas, promote detoxification, and restore Dhātu health.

॥ चिकित्सक निर्देशः ॥ (Clinician’s Note)

· Beware! Pārada Vikāra is a serious condition of heavy metal poisoning. While Ayurveda offers a sophisticated management protocol, it must be administered by an expert Rasa Vaidya in a controlled setting.
· Integrative Approach is Key: Modern diagnostics (blood/urine mercury levels) and emergency treatments (Chelation Therapy) should be integrated when necessary. The management can be a synergy of both sciences.
· Patient Education: Emphasize the absolute importance of consuming Rasa Auṣadhis only from authentic, qualified sources and under strict medical supervision.
