What is Nidana Sthana?

Nidana Sthana: The Chapter of Causes

Nidana Sthana, meaning "the chapter of causes" in Sanskrit, is the second chapter of the Charaka Samhita. It provides a detailed explanation of the causes (Nidana), pathogenesis (Samprapti), symptoms (Purva Rupa), and prognosis (Sadhyasadhyata) of various diseases.

Causes of Disease (Nidana): A Multifaceted Approach Nidana Sthana does not attribute the cause of disease to a single factor but considers it to be a complex interplay of various factors. The main causes include:


  • Diet: Overeating, unbalanced diet, improper food combinations, indigestion

  • Lifestyle: Lack of sleep, overwork, lack of exercise, irregular lifestyle

  • Environment: Changes in climate, seasonal transitions, polluted environment

  • Mental Factors: Stress, anger, sadness, anxiety, fear

  • Physical Factors: Injuries, infections, genetic factors


Pathogenesis (Samprapti): Dosha Imbalance and Disease Progression Nidana Sthana explains the pathogenesis of diseases as an imbalance in the doshas (Vata, Pitta, and Kapha) and the resulting changes in the body. When the balance of doshas is disrupted, the digestive fire (Agni) weakens, leading to the production of undigested toxins (Ama). This Ama accumulates in the body, adversely affecting tissues and organs, and is believed to cause various diseases.


Major Diseases Explained in Nidana Sthana

Nidana Sthana: Insights into Common Modern Ailments

Nidana Sthana discusses a wide range of diseases, many of which have parallels with common ailments prevalent in modern society. For example:


  • Digestive disorders: Irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), gastric ulcers, etc.

  • Metabolic disorders: Diabetes, obesity, dyslipidemia, etc.

  • Cardiovascular diseases: Hypertension, arteriosclerosis, heart disease, etc.

  • Respiratory diseases: Bronchial asthma, allergic rhinitis, etc.

  • Neuropsychiatric disorders: Depression, anxiety disorders, insomnia, etc.


While modern medicine classifies these as distinct diseases, Nidana Sthana views them through the lens of dosha imbalance, highlighting a common underlying factor.


Wisdom for Preventing Illness: Preventive Measures Taught by Nidana Sthana

Nidana Sthana emphasizes not only the diagnosis of diseases but also their prevention. By understanding and avoiding the factors that contribute to illness, one can prevent diseases before they manifest. Specifically, the following methods are recommended:


  • Diet: Consume a diet that suits your constitution and choose foods that are easy to digest.

  • Lifestyle: Maintain a regular daily routine, get moderate exercise, and ensure sufficient sleep.

  • Stress Management: Practice stress-relieving methods such as meditation and yoga.

  • Regular Cleansing: Undergo Ayurvedic purification therapies (Panchakarma) to eliminate toxins from the body.

Diagnostic Methods in Nidana Sthana: Pulse Diagnosis, Tongue Diagnosis, and Inquiry

Nidana Sthana employs various diagnostic methods to identify the cause of a disease and choose appropriate treatment. Among these, pulse diagnosis (Nadi Pariksha), tongue diagnosis (Jihva Pariksha), and inquiry (Prashna Pariksha) are particularly important.


Pulse Diagnosis: Decoding the Body's State through the Pulse Pulse diagnosis involves touching the radial artery at the wrist and diagnosing the body's condition based on the state of the pulse. In Ayurveda, the pulse is believed to reflect not only the heartbeat but also the movement and balance of the doshas (Vata, Pitta, and Kapha). A skilled Ayurvedic physician carefully observes the pulse's speed, strength, rhythm, and depth to diagnose dosha imbalances and abnormalities within the body.


Tongue Diagnosis: Assessing Constitution and Organ Health through the Tongue Tongue diagnosis involves assessing the tongue's color, shape, and coating to diagnose the body's constitution and the health of internal organs.

  • Tongue color: A red tongue suggests excess Pitta, a white tongue indicates excess Kapha, and a pale tongue suggests excess Vata.

  • Tongue shape: A thick tongue indicates excess Kapha, while a thin tongue suggests excess Vata.

  • Tongue coating: A white coating indicates excess Kapha, a yellow coating suggests excess Pitta, and a black coating suggests excess Vata.

Tongue diagnosis provides a visual understanding of the body's condition and plays a crucial role in Ayurvedic diagnosis.


Inquiry: Gathering Information through Patient Dialogue Inquiry involves gathering various information through dialogue with the patient, including lifestyle habits, dietary habits, medical history, family history, and mental state. Since Ayurveda considers the causes of disease to be diverse, the information obtained through inquiry is vital for diagnosis and determining treatment plans.

Comprehensive Diagnostic Assessment: Combining Pulse, Tongue, and Inquiry Findings In Ayurvedic diagnosis, the results of pulse diagnosis, tongue diagnosis, and inquiry are comprehensively assessed to determine the patient's constitution, the cause of the disease, and the progression of symptoms. Each of these diagnostic methods provides different information, and combining them enables a more accurate diagnosis.


Importance of Diagnostic Methods in Nidana Sthana The pulse diagnosis, tongue diagnosis, and inquiry explained in Nidana Sthana are indispensable in Ayurvedic diagnosis. By identifying the root cause of the disease through these diagnostic methods, it becomes possible to select the optimal treatment tailored to each individual patient.


Balancing the doshas and enhancing the body's natural healing powers

Nidana Sthana: Treatment Approaches and Their Unique Features


Nidana Sthana emphasizes the importance of restoring the balance of doshas and promoting internal cleansing to enhance the body's natural healing power in the treatment of diseases. Now that we have a deeper understanding of Nidana Sthana, let's delve into its main treatment methods and their characteristics.


Dietary Therapy: Balancing Doshas with a Diet Tailored to Your Constitution In Ayurveda, diet is considered the foundation of health. Nidana Sthana emphasizes the importance of choosing appropriate foods and cooking methods based on one's individual constitution (dosha).

  • Vata constitution: Consume warm, oily foods and avoid cold and dry foods.

  • Pitta constitution: Consume cool, light foods and avoid spicy and oily foods.

  • Kapha constitution: Consume warm, light, and dry foods and avoid sweet and oily foods.


Nidana Sthana also recommends choosing easily digestible foods, practicing moderation in eating, and avoiding excessive fluid intake during meals.

Herbal Therapy: Restoring the Body's Balance with the Power of Nature In Ayurveda, herbs are considered important tools for enhancing natural healing power. Nidana Sthana provides detailed descriptions of various herbs, their benefits, and methods of use.

  • Triphala: A combination of three fruits (Amla, Haritaki, and Bibhitaki) that is said to promote digestion, relieve constipation, and have detoxifying effects.

  • Ashwagandha: A herb that is said to have rejuvenating, stress-reducing, and immune-boosting effects.

  • Neem: A herb that is said to have antibacterial, detoxifying, and anti-inflammatory effects.


These herbs can be used alone or in combination with other herbs to create more effective formulations.

Purification Therapy (Panchakarma): Eliminating Toxins and Purifying the Body and Mind Panchakarma is a representative purification therapy in Ayurveda. It combines five cleansing methods: oil massage, sweat therapy, enema, vomiting therapy, and bloodletting. Panchakarma is said to have the effect of balancing the doshas and enhancing natural healing power by eliminating toxins (Ama) accumulated in the body.

Lifestyle Improvement: The Foundation for Maintaining Physical and Mental Health Nidana Sthana emphasizes that a regular lifestyle is essential for maintaining health.


  • Early to bed, early to rise: Strive for early to bed and early to rise to regulate the body's internal clock and ensure quality sleep.

  • Moderate exercise: Make it a habit to engage in exercise that suits you, such as yoga or walking, to promote blood circulation, boost metabolism, and maintain physical and mental health.

  • Stress management: Actively incorporate stress-relieving methods such as meditation, breathing exercises, and connecting with nature.


Nidana Sthana's Teachings on Root Cause Treatment Nidana Sthana imparts wisdom for identifying the root cause of illness and restoring true health by enhancing natural healing power. Aim to create a body that is less susceptible to illness by balancing the mind and body through a variety of approaches, including dietary therapy, herbal therapy, purification therapy, and lifestyle improvement.
