Introduction to Aṣṭāṅga Āyurveda

• The term “Aṣṭāṅga” derives from “aṣṭa” (eight) and “aṅga” (branch/limb).
• Aṣṭāṅga Āyurveda encapsulates the eight core areas of Ayurvedic practice, each specializing in different facets of health and disease management.
• It underscores Ayurveda’s holistic vision, ensuring comprehensive care through prevention, diagnosis, and treatment across diverse patient needs.

Key Scriptural References

• Caraka Saṃhitā and Suśruta Saṃhitā mention key domains, eventually consolidated and elaborated by Vāgbhaṭa in his works (Aṣṭāṅga Saṅgraha and Aṣṭāṅga Hṛdaya).

Kāya Chikitsā (Internal Medicine)

• “Kāya” means “body,” emphasizing diseases that affect the whole system (kāya) as opposed to localized conditions.
• Focus:

  • Treats common to complex systemic disorders (e.g., fever, digestive problems, metabolic diseases).
  • Caraka Saṃhitā is foundational for this branch.

Śalya Tantra (Surgery)
