Module Overview Module 1 establishes the complete theoretical foundation of Vedic Health Science, presenting the core principles through which Ayurveda understands the human body, its disorders, and the pathways to restoration. Drawing directly from the classical teachings of Caraka Saṁhitā, this module explains how health is maintained, how disease arises, and how the constitution of each individual determines treatment, longevity, and wellbeing.
Learners will explore the doṣas, dhātus, srotas, agni, āyu, and the laws governing proper and improper therapeutic timing. This module forms the intellectual backbone of the entire course, enabling students to understand all later modules—food science, lifestyle, ethics, sleep, epidemics, and spiritual healing—through a precise classical lens.

What This Module Covers

1. Causes of Disease in the Human Body

A detailed study of the three primary causes of disease—asātmyendriyārtha saṁyoga, prājñāparādha, and kāla‑pariṇāma—and how imbalance arises from improper sensory use, errors of judgment, and seasonal changes.

  • Causes of disease

2. Constitutional Doṣas and Their Treatment

Understanding vāta, pitta, and kapha as governing principles of physiology, psychology, and pathology. Students learn how doṣas become aggravated, how they manifest, and how they are pacified through diet, lifestyle, and medicine.

  • Doṣa theory

**3. Disorders of the Body Channels

\(Srotas\)

and Their Treatment**

A complete mapping of the srotas—the body’s channels of transport—and how their obstruction, depletion, or overflow leads to disease. Treatment principles for each channel are explained.

4. Dhātu Disorders and Their Treatment

Study of the seven dhātus—rasa, rakta, māṁsa, meda, asthi, majjā, śukra—their nourishment cycle, depletion, aggravation, and therapeutic correction.

  • Dhātu theory

**5. Special Discussion on the Blood Dhātu

\(Rakta\)

**

Rakta as the seat of life, its disorders, purification methods, and its role in inflammatory and systemic diseases.

6. Nature of the Bodily Agni

Agni as the central fire of digestion, metabolism, immunity, and cellular intelligence. Types of agni, signs of imbalance, and correction strategies.

  • Agni

**7. Opposite Treatment

\(Viparīta Cikitsā\)

**

The classical rule of treating disease by applying the opposite qualities—hot vs. cold, heavy vs. light, dry vs. unctuous—based on doṣa dominance.

8. Use of Hot Water in Fever

A precise explanation of when hot water is beneficial, when it is harmful, and how its qualities interact with doṣas during fever.

9. Examination of the Patient’s Age

Age‑based diagnostic principles, showing how childhood, adulthood, and old age influence doṣa dominance and treatment selection.

10. Season for Bodily Purification

Understanding when pañcakarma is safe, effective, and contraindicated based on seasonal strength, doṣa behavior, and digestive fire.

11. Proper and Improper Time for Medicine Administration

Rules governing timing of medicines—before food, after food, during digestion, during fasting—and how timing changes therapeutic outcomes.

12. Classification of Substances According to Their Nature

A systematic classification of all substances based on rasa, guṇa, vīrya, vipāka, and prabhāva, forming the basis of Ayurvedic pharmacology.

Introduction Free preview Ayurveda, originating in India, is a holistic science of life that extends beyond human medicine to include all living creatures. It emphasizes the preservation of health through a balanced lifestyle, proper nutrition, and understanding the interplay of body, senses, mind, and soul. While wholesome food promotes health, other factors like unsuitable timing, mental errors, and environmental influences can also impact well-being. The text discusses the influence of diet, lifestyle, and bodily constitution on health and disease. It explains how different foods and environmental factors affect the doshas (vata, pitta, kapha), and how a balanced constitution (samadhātu prakṛti) is considered healthy. The text also describes the characteristics of vata, pitta, and kapha constitutions, and suggests dietary and lifestyle choices based on one’s constitution.
2
Causes of Disease in the Human Body Diseases are classified as external (āgantuka) or internal (nija), with external diseases originating from external causes and internal diseases arising from imbalances of vāta, pitta, and kapha. Both types of diseases can be caused by incompatible sensory experiences, errors of intellect, and the natural progression of disease. While the four types of diseases can become interconnected, their symptoms remain distinct.
3
Constitutional Doṣas and Their Treatment Ayurvedic medicine recognizes three doshas: vata, pitta, and kapha. Each dosha has specific locations in the body and associated diseases when aggravated. Treatments for each dosha imbalance include dietary adjustments, lifestyle changes, and specific therapies like enemas, purgation, and emesis, targeting the root location of the dosha.
4
Disorders of the Body Channels and Their Treatment The body contains thirteen channels, each associated with a specific root and function, such as transporting prana, blood, or waste. These channels, which can be visible or invisible, are susceptible to contamination by vata, pitta, and kapha, leading to disease. Contamination can be caused by factors like diet, lifestyle, and suppressed urges, and manifests through symptoms like excessive discharge or obstruction. The Charaka Saṃhitā, Vimānasthāna 5.6.15 describes the symptoms, causes, and treatments for contamination of various bodily channels (srotas). Contamination of the udakavaha channel, responsible for water transport, leads to dryness and thirst, caused by factors like hot food, alcohol, and thirst suppression. Treatment involves addressing excessive thirst.
5
Dhātu Disorders and Their Treatment The text discusses various diseases caused by the aggravation of vāta, pitta, and kapha doṣas in different body tissues (dhātu). It details the symptoms and treatments for diseases affecting rasa, blood, muscle, fat, bone, marrow, and semen. Treatments include lightening therapies, purgation, bloodletting, emesis, and lifestyle modifications. The Charaka Saṁhitā and Trimarmīya Cikitsā describe various diseases affecting the senses, particularly the nose and mouth. These diseases, caused by imbalances in the three doshas (vāta, pitta, and kapha), manifest with specific symptoms and require tailored treatments. Neglecting these diseases can lead to complications, impacting overall health and well-being. The text describes various diseases and their symptoms, including mouth, ear, and eye diseases caused by imbalances in the three doshas (vata, pitta, and kapha). It also outlines treatments for these diseases, such as oleation, sudation, nasal therapy, and specific dietary recommendations.
6
Special Discussion on the Blood Dhātu Blood, the foremost dhatu, is vital for life and depends on proper diet and lifestyle for purification. Vitiated blood, caused by various factors including diet and lifestyle, leads to numerous diseases. Treatment for blood-origin diseases involves pacifying blood and pitta through purgation, fasting, or bloodletting, with specific dietary guidelines following bloodletting.
7
Nature of the Bodily Agni The body has four types of agni: tīkṣṇa, manda, sama, and viṣama. These types are determined by the balance of vāta, pitta, and kapha doshas in an individual.
8
Opposite Treatment (Viparīta Cikitsā) Diseases are treated with methods opposite to their cause, such as using cold substances for heat-origin diseases and nourishment for depletion diseases. Apatarpaṇa, or depletion, is categorized into laṅghana (fasting), pācana (digestive therapies), and avasecana (elimination therapies), with the method chosen based on the strength of the doṣas.
9
Use of Hot Water in Fever Hot water is used to treat fever because it digests doshas, especially those arising from the āmāśaya. However, it should be avoided in cases of aggravated pittaja fever or diarrhea with burning, delirium, and confusion.
10
Examination of the Patient’s Age The age of a patient is categorized into childhood (up to 16 years), middle age (16-60 years), and old age (60-100 years). These categories are determined by the maturity of the body’s dhātus and the predominance of kapha, pitta, and vāyu.
11
Season for Bodily Purification Ayurveda divides the year into six seasons for bodily purification, with specific procedures prescribed for each. Purgation is recommended for pitta in Prāvṛṭ, emesis for kapha in Śarada, and enema for vāta in Vasanta. However, purification is discouraged in Hemanta, Grīṣma, and Varṣā due to extreme weather conditions that can lead to complications.
12
Proper and Improper Time for Medicine Administration Ayurveda distinguishes between kāla (proper time) and akāla (improper time) for administering medicine, emphasizing the importance of timing for effectiveness.
13
Classification of Substances According to Their Nature Ayurveda classifies medicinal substances based on their nature and properties. The text categorizes substances into emetic, purgative, and those with sweet, sour, salty, pungent, bitter, and astringent tastes, providing examples for each category.
