NIDANAPANCHAKA AND ELABORATION OF NIDANA, PURVARUPA AND LAKSHANA AS PER JWARA NIDANA

NIDANAPANCHAKA AND ELABORATION OF NIDANA, PURVARUPA AND LAKSHANA AS PER JWARA NIDANA (CHA. NI. 1) – WITH MODERN CORRELATION

In Ayurveda, the diagnosis of a disease is based on a fivefold diagnostic approach called Nidanapanchaka, which forms the foundation of clinical understanding. Charaka Samhita, Nidana Sthana, particularly the first chapter – Jwara Nidana Adhyaya, elaborates these principles using Jwara (Fever) as a representative disease. The systematic study of these components ensures accurate diagnosis and treatment.

NIDANAPANCHAKA – THE FIVEFOLD DIAGNOSTIC TOOL
Nidanapanchaka includes:

• Nidana (Causative factors)

• Purvarupa (Premonitory symptoms)

• Rupa (Lakshana – Manifested symptoms)

• Upashaya (Relieving/Aggravating factors)

• Samprapti (Pathogenesis)

NIDANA (CAUSES OF DISEASE)
Nidana refers to the causative factors that initiate the disease process. It includes dietary, behavioral, psychological, environmental, and infective causes. In Jwara Nidana, Charaka elaborates various causes which provoke Tridosha, leading to fever.

Sanskrit Reference:
"कुप्यन्त्यत्र दोषाः सर्वे ज्वरहेतोः प्रवर्तकाः।
सर्वेभ्यो ह्यन्नपानेभ्यो ज्वरकारणता स्मृता॥"
(Cha. Ni. 1/6)

Key Ayurvedic Causes of Jwara:

• Excessive intake of Guru, Snigdha, Abhishyandi Ahara

• Viruddha Ahara (incompatible food)

• Ajirna (indigestion)

• Vegadharana (suppression of natural urges)

• Exposure to cold after heavy exertion or hot bath

• Ratri Jagarana (night awakening)

• Manasika Nidana – Shoka, Bhaya, Krodha

Modern Correlation of Causative Factors:

• Infections – Viral, bacterial, protozoal organisms

• Inflammatory disorders – Autoimmune fevers

• Heatstroke, drug reactions, neoplasms

• Poor lifestyle and hygiene

• Environmental exposure – contaminated food/water

• Stress and sleep disturbances

PURVARUPA (PREMONITORY SYMPTOMS)
Purvarupa are subtle signs that appear before the full manifestation of the disease. Recognizing them allows early preventive care.

Sanskrit Reference:
"यदा ज्वरस्य सञ्ज्ञायां पूर्वरूपाण्युपद्यते।
शिरःकम्पोऽङ्गसादश्च तन्द्रा गौरवमत्ययः॥"
(Cha. Ni. 1/17)

Purvarupa of Jwara as per Charaka:

• Shirokampana – Trembling of head

• Angasada – Fatigue, weakness in limbs

• Tandra – Drowsiness

• Gaurava – Heaviness of body

• Jrimbha – Yawning

• Aruchi – Anorexia

• Ushnabhilasha – Desire for warmth

Modern Correlation:
These correspond to prodromal symptoms seen in fevers like:

• Malaise

• Fatigue

• Drowsiness

• Headache

• Muscle ache

• Loss of appetite
  These symptoms often precede infections like influenza, malaria, dengue, etc.

RUPA / LAKSHANA (SYMPTOMS)
Rupa refers to fully developed clinical symptoms after the disease manifests.

Sanskrit Reference:
"स्निग्धोष्णं लघु सूक्ष्मं च ज्वरशब्दोऽयमर्थकः।
क्लेदित्वाच्छरीरस्य समवेत्तुर्विषादतः॥"
(Cha. Ni. 1/4)

Lakshana of Jwara:

• Santapa (high temperature)

• Angamarda (body ache)

• Agnimandya (loss of appetite)

• Trishna (thirst)

• Murchha (fainting tendency in high fever)

• Shiro Ruk (headache)

• Jrimbha (yawning)

• Chhardi (vomiting)

• Tandra (drowsiness)

• Gaurava (heaviness)

Sanskrit Sloka (Tridoshaja Jwara Lakshana):
"तत्र वातजज्वरे कम्पः कम्पः स्तब्धता रुजः।
शुष्कास्यत्वं च सङ्कोचः शीतस्पर्शत्वमेव च॥
पित्ते सन्तापदाहार्तिरत्यग्निस्तृष्णया हतिः।
स्वेदे स्विन्नाङ्गता दाहो दाहो मूर्च्छा भ्रमस्तथा॥
कफे गुरुगात्रत्वं स्तब्धता चातिसद्ग्रणिः।
प्रलापश्च विवर्णत्वं निःस्वं स्वप्नो गुरुस्वरः॥"
(Cha. Ni. 1/19-22)

Modern Correlation of Lakshana (Symptoms of Fever):

• Increased body temperature (Pyrexia)

• Malaise and fatigue

• Headache and myalgia

• Loss of appetite, nausea, vomiting

• Chills or sweating depending on cause

• Dehydration (due to increased insensible loss)

• Altered mental status in severe fevers
  These symptoms are consistent with clinical picture of fevers like Typhoid, Malaria, Dengue, Influenza, Septicemia, etc.
