Roga Nidana BAMS paper 1 syllabus concepts nidana panchaka trividha pariksha shloka Charaka Sushruta
Now I have a thorough picture of the Roga Nidana Paper 1 syllabus. Let me compile a comprehensive answer from the syllabus topics, classical shlokas, and the extracted content.
Roga Nidana - Paper 1: All Concepts (Exam Point of View)
Based on the BAMS/NCISM syllabus, Roga Nidana Paper 1 is divided into the following major units. Each concept is explained below with its reference shloka, definition, classification, and exam-relevant bullet points.
PART A: DOSHA DUSHYADI VIGYANA
1. Definition and Importance of Roga Nidana
Definition Shloka (Charaka Sutrasthana 1/24):
"Hetu Linga Aushadham Jnanam Swasthasyorjanam Param | Vyadhitasya Vikara Prashamanartham Param Matam ||"
(Knowledge of cause, symptoms and medicine - for the healthy to maintain health and for the diseased to cure disease.)
- Roga Nidana = Science of diagnosis of disease (Roga = disease; Nidana = cause/diagnosis)
- Also called Vikriti Vijnana - study of pathological changes
- It encompasses etiology, pathogenesis, clinical features, and prognosis
- Bridge between physiology (Kriya Sharira) and clinical medicine
- Exam tip: Roga Nidana is a 2nd BAMS subject; its study is essential before clinical practice
2. Samanya Nidana & Samanya Lakshana of Dosha Prakopa/Kshaya
Shloka (Charaka Sutrasthana 17/63) - Trividha Hetu:
"Asatmyendriyarthasanyogah Prajnaparadham Tatha Eva Ca | Kaalaparinama Itityesha Tridhaa Rogasya Samgraham ||"
(The three general causes of disease are: unwholesome contact of sense organs, intellectual error/Prajnaparadha, and seasonal/time-related factors.)
Dosha Prakopa (Aggravation) Samanya Lakshana:
- Vata Prakopa: Rukshata (dryness), Parusata, Laghava, Chala, Sita (cold), Khara, Vishada guna increase
- Pitta Prakopa: Daha (burning), Paka (inflammation), Sweda (perspiration), Raga (redness), Kleda
- Kapha Prakopa: Gaurava (heaviness), Sthaimithya (stability), Sheeta (cold), Snigdha (oiliness), Manda (dullness)
Dosha Kshaya (Decrease) Samanya Lakshana:
- Vata Kshaya: Jadya (inactivity), Manda cheshtata, Kapha Laxana predominance
- Pitta Kshaya: Mandagni, Prabha Kshaya (loss of lustre), Sheeta sparsha
- Kapha Kshaya: Daurbalya, Bhrama, Hridaya Shosha, Sandhi Shaithilya
3. Vikriti Vijnana of Pancha Vidha Dosha Bheda
Shloka (Charaka Chikitsa 28/9-11) - Vata Bheda:
"Praana Udaana Samaana Apaanau Vyaana Eva Ca | Panchaiva Vaayu Bhedaastu Pranavayu Varishthakah ||"
- 5 types of Vata: Prana, Udana, Samana, Apana, Vyana - location and functions
- 5 types of Pitta: Pachaka, Ranjaka, Sadhaka, Alochaka, Bhrajaka
- 5 types of Kapha: Kledaka, Avalambaka, Bodhaka, Tarpaka, Shleshaka
Exam tip: Each sub-dosha has a specific Sthana (seat), Karma (function), and Vikriti Lakshana (features when vitiated) - know all three for each sub-type.
4. Dosha Dhatu Ashraya-Ashrayi Bhava
Shloka (Charaka Sutrasthana 20/9):
"Aashraya Aashrayee Bhaavas Tu Dosha Dhaatvor Matah | Doshaa Aashrayanti Dhaatoonaamstena Taddosha Samsrayah ||"
- Doshas are Ashrayi (residents/tenants); Dhatus are Ashraya (containers/hosts)
- When Doshas are vitiated, they affect their resident Dhatus and produce disease
- Eg: Rakta Dhatu is the Ashraya of Pitta - hence Pitta vikriti often presents as Rakta pradoshaja vikara (Raktapitta, Visarpa)
- Clinical significance: Helps in identifying which Dhatu is affected based on symptoms
5. Dhatu Kshaya, Vriddhi Lakshana & Pradoshaja Vikara
Shloka (Charaka Sutrasthana 17/65-66):
"Rasasya Kshayo Hridi Shunyata Shramanam Shwasah | Srotasam Shoshaha Daurbalyam Shabdakshama Cha ||"
(Decrease of Rasa Dhatu causes emptiness in heart, fatigue, breathlessness.)
| Dhatu | Kshaya Lakshana | Vriddhi Lakshana |
|---|---|---|
| Rasa | Hridaya Shunyata, Shrama | Praseka (salivation), Gaurava |
| Rakta | Ruksha Twacha, Sira Shosha | Abhishyanda, Visarpa, Kushtha |
| Mamsa | Sphik-Uru-Griva Shosha | Granthi, Arbuda |
| Meda | Pleeha Vriddhi, Karsya | Sthoulya, Udara |
| Asthi | Asthi Shoola, Danta Bhanga | Asthi Vriddhi, Atirikta Asthi |
| Majja | Bhrama, Daurbalya | Gaurava, Netra Vriddhi |
| Shukra | Napumsakatwa, Daurbalya | Atimaithuna Shakti |
Pradoshaja Vikara = diseases caused when Dhatus are disturbed/vitiated:
- Eg: Rakta Pradoshaja = Vishisphota, Visarpa, Raktapitta, Kushtha
6. Upadhatu Pradoshaja Vikara
- Upadhatava = secondary tissues formed from Dhatus (not main Dhatus but byproducts)
- Examples: Stanya (from Rasa), Raja/Artava (from Rasa/Rakta), Kandara/Sira (from Mamsa), Vasa (from Meda), Snayu (from Mamsa/Asthi), Danta (from Asthi), Kesha/Roma (from Asthi/Majja)
- Their diseases are called Upadhatu Pradoshaja Vikara
7. Mala Kshaya, Vriddhi Lakshana & Pradoshaja Vikara
Shloka (Ashtanga Hridayam Sutrasthana 11):
"Purisha Mutra Sweda Iti Tridhaa Mala Prakirtitah | Tesham Kshayavriddhi Dushti Cha Deha Dosha Karanam ||"
- 3 types of Mala: Purisha (stool), Mutra (urine), Sweda (sweat)
- Purisha Kshaya: Adhmana (distension), Vata Shoola, Kukshi Shoola
- Purisha Vriddhi: Aadhmana, Daurgandhya, Gudagoola
- Mutra Kshaya: Mutra Kriccha, Gourava
- Mutra Vriddhi: Mutraghata, Atisara
- Sweda Kshaya: Romakupa Sanga, Twak Rukshata, Shrama
- Sweda Vriddhi: Durgandha, Kandu (itching)
8. Indriya Pradoshaja Vikara
- When 5 sense organs (Pancha Jnanendriya) are vitiated:
- Chakshu (Eye) vikriti: Timira, Kachha, Linganasha
- Shrotra (Ear) vikriti: Badhirya, Karna Kshweda
- Ghrana (Nose) vikriti: Pratishyaya, Nasa Paka
- Jihva (Tongue) vikriti: Muka Paka, Aruchi
- Twak (Skin) vikriti: Kushtha, Visarpa, Vata Vyadhi
9. Hetu - Bheda and Lakshana of Agni Dushti
Shloka - Agni Charcha (Charaka Chikitsa 15/3-4):
"Samaagni Vikrutou Dehe Sarvarogaah Prajaayate | Samaagni Praaptou Pumsa Aarogyam Jeevanam Cha Tat ||"
(When Agni is disturbed all diseases arise; when Agni is balanced, health and life are maintained.)
- 4 types of Agni:
- Samagni - balanced, ideal state
- Vishamagni - irregular (Vata dominant), causes alternating constipation/diarrhoea
- Teekshnagni - sharp (Pitta dominant), causes hyperacidity, Pitta disorders
- Mandagni - slow (Kapha dominant), causes Aama formation, obesity
PART B: NIDANA PANCHAKA VIGYANA
10. Nidana Panchaka - Introduction
Defining Shloka (Madhava Nidana 1/4):
"Nidanam Purva Rupam Cha Rupam Samprapti Reva Ca | Upashayashcha Panchaite Nidanarthah Prakirtitaah ||"
(Nidana, Purvarupa, Rupa, Samprapti, and Upashaya - these five are declared as the means of diagnosis of disease.)
- Nidana Panchaka = Five diagnostic tools used in Ayurvedic clinical examination
- They give complete picture of disease - from cause to manifestation
- Without Nidana Panchaka, disease diagnosis is incomplete
- Roga Pariksha (examination of disease) uses Nidana Panchaka; Rogi Pariksha (examination of patient) uses Dashavidha Pariksha, Ashtasthana Pariksha
11. Nidana (Hetu) - Causative Factor
Shloka (Charaka Sutrasthana 1/23):
"Tatra Nidaanam Kaaranam Ityuktamagre | Sa Hetu Nidanam Karanam Ayatana Nimittam Cha ||"
(Nidana means cause - it is also called Hetu, Karana, Ayatana, and Nimitta.)
Synonyms: Hetu, Karana, Ayatana, Nimitta, Prakriti (in context)
Classification of Hetu:
| Classification | Types |
|---|---|
| Trividha Hetu (3 types - Charaka) | Asatmyendriyartha Samyoga, Prajnaparadha, Parinama (Kala) |
| Based on origin | Bahya (external), Abhyantara (internal) |
| Based on function | Utpadaka (disease producing), Vyanjaka (disease manifesting) |
| Based on potency | Balavat (strong), Durbala (weak) |
| Based on time | Sannikrishta (proximate), Viprakrishta (remote) |
Exam point: Trividha Nidana is most asked:
- Asatmyendriyartha Samyoga = Atiyoga (excess), Ayoga (deficient), Mithyayoga (improper use) of sense objects
- Prajnaparadha = intellectual error; failure to use intellect, memory, and restraint
- Parinama/Kala = seasonal/time factors
12. Purvarupa - Prodromal Symptoms
Shloka (Charaka Vimana 4/7):
"Vyaktaanaam Vikaaraanaam Poorvam Roopaani Yaanyuta | Shuktaanaam Asataamvaa Poorvaroopam Tad Uchyate ||"
(The signs that appear before the full manifestation of disease, or the unclear/mild signs - these are called Purvarupa.)
Synonyms: Purvarupa, Premonitory symptoms, Prodromal features
Types:
- Samanya Purvarupa = common to many diseases (e.g., Agnimandya, Aruchi)
- Vishishtha Purvarupa = specific to one disease (e.g., Avipaka in Jwara; Hastapadatala Daha in Prameha)
Clinical Importance:
- Indicates upcoming disease - allows early prevention
- If few prodromal symptoms: Sadhya (curable)
- If moderate prodromal symptoms: Kriccha Sadhya (difficult to cure)
- If all prodromal symptoms present: Asadhya (incurable)
- Used in differential diagnosis - different diseases have different Purvarupa
13. Rupa - Clinical Features / Signs & Symptoms
Shloka (Charaka Vimana 4/7):
"Praadurbhootasya Vikaarasya Lakshanam Yad Bhavet Sphutam | Vyaktam Lingam Rupam Cha Aakrutiriti Ucyate ||"
(The clear and manifest signs of an already present disease are called Rupa/Linga.)
Synonyms: Rupa, Linga, Lakshana, Chinha, Akruti
Types:
- Samanya Lakshana = general symptoms common to many diseases
- Pratyatma Lakshana = pathognomonic/specific symptom of one disease (e.g., Kasa + Jwara + Raktasthivana in Rajayakshma)
Difference between Vyadhi and Lakshana:
- Vyadhi = the disease entity itself (e.g., Jwara)
- Lakshana = symptom/sign that defines the disease (e.g., Santapa in Jwara)
Importance of Rupa:
- Confirms diagnosis
- Planning treatment - both Nidana Parivarjana and Chikitsa
- Prognosis: If all symptoms present = Asadhya
14. Samprapti - Pathogenesis
Shloka (Madhava Nidana 1/5):
"Sampraapti Rogajanma Eva Jneya Ghatakaih Saha | Dosha Dushya Samuurcchanaa Rogotpattih Prakirtitaa ||"
(Samprapti is the birth of disease; it is understood along with its constituent factors - the mixing of vitiated Doshas with Dushyas is the production of disease.)
Synonyms: Samprapti, Agati, Jati, Utpatti, Kriya
Types of Samprapti:
- Sankhya Samprapti = total number of disease types (e.g., 8 types of Jwara)
- Pradhanya Samprapti = predominant Dosha in the disease
- Bala Samprapti = strength/severity of disease
- Nidana Samprapti = nature/type of causative factor
- Vikalpa Samprapti = relative proportion of Dosha involvement
- Kala Samprapti = time and seasonal factors
Samprapti Ghataka (constituents of pathogenesis):
- Dosha (which is vitiated)
- Dushya (tissue/system affected)
- Agni (digestive fire status)
- Aama (presence/absence of undigested toxins)
- Srotas (channels involved)
- Srotodushti (type of channel dysfunction)
- Udbhava Sthana (site of origin)
- Sanchara Sthana (site of spread)
- Vyakti Sthana (site of manifestation)
- Vyanjaka (factors that manifest the disease)
- Rogamarga (pathway - Bahya, Madhyama, Abhyantara)
Shat Kriyakala (Six stages of disease):
"Sanchayo Prakopastu Prasara Sthana Samshraya | Vyakti Cha Bheda Iti Shadkriyakala Prakirtitah ||"
- Sanchaya (accumulation in own site)
- Prakopa (aggravation/agitation)
- Prasara (spreading from origin)
- Sthanasamshraya (lodging at new site - Purvarupa appears here)
- Vyakti (full manifestation - Rupa appears here)
- Bheda (chronicity/complications)
15. Upashaya / Anupashaya - Therapeutic Test
Shloka (Charaka Sutrasthana 10/3):
"Hetu Vyadhi Vipritartham Karma Dravyam Tad Upashayah | Anupashayo Viparyayah ||"
(Upashaya is the drug, diet or regimen that is opposite to the cause or the disease; Anupashaya is its opposite.)
Synonyms: Upashaya = Satmya, Pathya, Hitakara; Anupashaya = Asatmya, Apathya
Types of Upashaya (18 types - 3 x 3 x 2 matrix):
By mode (3):
- Hetu Viparita = opposite to cause
- Vyadhi Viparita = opposite to disease
- Hetu-Vyadhi Viparitarthakari = relieves both cause and disease
By modality (3):
- Aushadha (medicine)
- Anna (diet)
- Vihara (regimen/lifestyle)
Both Upashaya and Anupashaya make 3 x 3 x 2 = 18 types.
Importance:
- Used for Gudha Linga Vyadhi (diseases with hidden symptoms) - Charakokta: "Gudha Lingam Vyadhim Upashayaabhyam Parekshet"
- Used when diagnosis is unclear - therapeutic trial confirms the disease
- Eg: If Shotha subsides with warm application = Vata Kapha Shotha confirmed
16. Pariksha Vigyana - Methods of Examination
Trividha Pariksha (Charaka):
"Aptopadesha Prathyaksha Anumaanam Iti Tridhaa Pariksha |"
- Aptopadesha (Shabda) = authoritative textual knowledge (accepting what Apta/reliable author says)
- Pratyaksha = direct perception by sense organs
- Anumana = inference/reasoning
Chaturvidha Pariksha (Sushruta):
Aptopadesha + Pratyaksha + Anumana + Yukti (logical interpretation)
Shadvidha Pariksha (Charaka Vimana):
Pratyaksha + Anumana + Aptopadesha + Upamana (comparison) + Aithihya (tradition) + Yukti
Ashtasthana Pariksha (Eight-point examination):
"Nadi Mutra Malam Jihva Shabda Sparsha Druk Aakruti | Ashtasthana Pariksha Iti Vaidya Shastra Prakirtitam ||"
- Nadi (Pulse)
- Mutra (Urine)
- Mala (Stool)
- Jihva (Tongue)
- Shabda (Voice/Sound)
- Sparsha (Touch/Skin)
- Druk (Eyes/Vision)

17. Dashavidha Pariksha (Ten-fold patient examination)
Shloka (Charaka Vimana 8/94):
"Prakriti Vikriti Sara Samhanana Pramana Satmya Satwa Ahara Shakti Vyayama Shakti Vaya | Iti Dashavidha Parikshya Bhaavaa Bhavanti ||"
- Prakriti (body constitution - Vata, Pitta, Kapha, Dvandva, Tridoshaja, Sama)
- Vikriti (pathological changes)
- Sara (quality of body tissues - Rasa Sara, Rakta Sara...Shukra Sara)
- Samhanana (compactness of body)
- Pramana (body measurements/proportions)
- Satmya (homologation/adaptability)
- Satwa (mental strength/psychic constitution)
- Ahara Shakti (digestive capacity)
- Vyayama Shakti (exercise/physical capacity)
- Vaya (age)
18. Sapeksha Nidana - Vyavacchedaka Nidana (Differential Diagnosis)
Shloka (Charaka Vimana 4/4):
"Samaanam Lakshanaabhyaam Dwa Vyadhii Bhavato Yadaa | Tataa Sapeksha Nidaanam Vyavacchedakam Uttamam ||"
(When two diseases share similar symptoms, differential diagnosis by comparing distinguishing features is necessary.)
- Vyavacchedaka Nidana = Differential diagnosis - distinguishing one disease from another with similar presentation
- Applies to:
- Ukta Vyadhi (diseases described in classics) - compare Pratyatma Lakshana
- Anukta Vyadhi (diseases not described) - use Hetu, Dosha, Dushya analysis
Example: Jwara vs Daha - both have heat; Jwara has Santapa (systemic fever) while Daha is localized burning
19. Vyadhi - Definition, Classification, and Nomenclature
Shloka (Charaka Sutrasthana 9/4):
"Rogaah Sarve Api Mandagnau | Naanaagadaa Naanaopasargaah ||"
Definition: "Dukhanaamaabhisambandhaat Roga Iti Abhidhiyate" - that which causes Dukha (suffering) is called Roga/Vyadhi
Classification of Vyadhi:
- Based on Dosha: Vataja, Pittaja, Kaphaja, Sannipataja, Agantuja
- Based on origin: Nija (endogenous), Agantuja (exogenous - injury, poison, spirit)
- Based on treatability: Sadhya (curable), Kriccha Sadhya (difficult), Yapya (palliatable), Asadhya (incurable)
- Based on Rogamarga: Shakha (Bahya), Koshtha (Madhyama), Marma/Asthi/Sandhi (Abhyantara)
Vyadhi Naamakarana (Naming of diseases):
- Named after Dosha (e.g., Vatavyadhi)
- Named after Dushya (e.g., Raktapitta)
- Named after Sthana (e.g., Hridroga)
- Named after Nidana (e.g., Vishaja)
- Named after Rupa (e.g., Atisara - excessive loose stools)
20. Upadrava and Udarka
Upadrava (Complication):
- Shloka: "Rogotpattou Yadutpadyate Rogantaram Tadupasargah Upadravah Ca"
- Complications arising during the course of a disease
- Eg: Murccha, Arochaka, Trishna in Jwara
Udarka (Sequelae):
- Effects/residues that arise after the disease subsides
- Eg: Post-Jwara weakness (Daurbalya), Aruchi
21. Arishta Vijnana - Signs of Death / Poor Prognosis
Shloka (Charaka Indriya Sthana 1/5):
"Indriyaarthe Bhayam Yaitu Vishayeshvabhijayate | Arishta Vigyanam Iti Proktam Acharya Purvakaiah ||"
- Arishta = bad omen / sign indicating imminent death or very poor prognosis
- Nimittaja Arishta = ominous signs related to appearance, colour, smell, etc.
- Swabhavaja Arishta = natural signs of decline
- Knowledge of Arishta helps in deciding treatability and counselling family
22. Sadhyasadhyatwa - Prognosis
Shloka (Ashtanga Hridayam Sutrasthana 2/49):
"Sadhyam Kriccha Sadhyam Yaapyam Asaadhyam Cha Chaturvidhah | Vyadhinaam Sadhya Sadhyatwa Gneyam Rogabalam Vina ||"
4 Types of Prognosis:
- Sukha Sadhya = easily curable
- Kriccha Sadhya = difficult to cure
- Yapya = can be managed/palliated but not cured (like diabetes)
- Asadhya = incurable
Factors affecting prognosis (Trividha Bala):
- Roga Bala (strength of disease)
- Rogi Bala (strength of patient)
- Aushadha Bala (strength of medicine)
