Kaya Chikitsa (Internal Medicine) in Ayurveda: Complete Guide
Kaya Chikitsa is one of the most important and comprehensive branches of Ayurveda. Often compared with Internal Medicine in modern healthcare, Kaya Chikitsa deals with the diagnosis, management, and prevention of systemic diseases affecting the entire body.
The term Kaya Chikitsa comes from two Sanskrit words:
- Kaya – Body (and also refers to Agni or metabolism)
- Chikitsa – Treatment or therapy
Thus, Kaya Chikitsa focuses on treating diseases by restoring metabolic balance and correcting internal bodily functions.
Historical Background of Kaya Chikitsa
Kaya Chikitsa has deep roots in classical Ayurvedic texts such as:
- Charaka Samhita
- Sushruta Samhita
- Ashtanga Hridaya
Among these, the Charaka Samhita is considered the primary text for Kaya Chikitsa, as it extensively discusses internal medicine, pathogenesis, diagnosis, and treatment protocols.
Acharya Charaka emphasized understanding the root cause (Nidana) of diseases rather than merely suppressing symptoms.
What Does Kaya Chikitsa Cover?
Kaya Chikitsa deals with:
- Digestive disorders
- Respiratory diseases
- Metabolic disorders
- Skin diseases
- Fever (Jwara)
- Diabetes (Madhumeha)
- Arthritis
- Liver disorders
- Psychological conditions
It is the most clinically oriented branch of Ayurveda and forms the foundation of BAMS education.
Core Principles of Kaya Chikitsa
Tridosha Theory
Kaya Chikitsa is based on the balance of Vata, Pitta, and Kapha. Disease occurs when these doshas become imbalanced.
Agni (Digestive Fire)
Agni plays a central role in internal medicine. Weak or disturbed digestion leads to toxin accumulation (Ama), which becomes the root cause of many diseases.
Ama (Toxins)
Ama forms due to improper digestion and blocks body channels (Srotas), leading to systemic disorders.
Dhatu (Body Tissues)
Seven body tissues (Rasa, Rakta, Mamsa, Meda, Asthi, Majja, Shukra) must remain balanced for health.
Diagnostic Methods in Kaya Chikitsa
Ayurvedic diagnosis differs from modern pathology. It includes:
Nadi Pariksha (Pulse Diagnosis)
Helps identify dosha imbalance.
Ashtavidha Pariksha (Eight-fold Examination)
- Pulse
- Urine
- Stool
- Tongue
- Speech
- Touch
- Eyes
- General appearance
Dashavidha Pariksha (Ten-fold Examination)
Includes assessment of body constitution, strength, age, mental status, etc.
Diagnosis focuses on identifying the root cause rather than just the disease label.
Common Diseases Treated in Kaya Chikitsa
Jwara (Fever)
Ayurveda classifies fever into Vata, Pitta, Kapha, and mixed types.
Prameha (Diabetes)
Known as Madhumeha, treated with herbs, diet regulation, and detox therapies.
