Astang Ayurveda: The 8 Classical Faculties अष्टाङ्ग आयुर्वेद — The Eight Pillars of Vedic Medicine

Ayurveda is not a generalized folk tradition—it is an encyclopedic, eight-faculty clinical science codified thousands of years ago in the Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya. At Art of Ayurveda, our institution preserves the undiluted authenticity of these eight sacred branches of healing.

काय-बाल-ग्रहोर्ध्वाङ्ग-शल्य-दंष्ट्रा-जरा-वृषान् ।
अष्टावङ्गानि तस्याहुश्चिकित्सा येषु संश्रिता ॥
— अष्टाङ्गहृदयम्, सूत्रस्थानम् (१.५) / Ashtanga Hridaya, Sutrasthana (1.5)
Classical Authority: “Internal medicine (Kayachikitsa), pediatrics & gynecology (Kaumarbhritya), psychiatry & mind (Bhuta Vidya), head, ENT & eyes (Shalakya Tantra), surgery & musculoskeletal (Shalya Tantra), toxicology & environmental cleansing (Agada Tantra), rejuvenation & geriatrics (Rasayana), and virility & reproductive vitality (Vajikarana)—these eight faculties comprise the complete therapeutic universe of Ayurveda.”

Foundations of Ashtanga Ayurveda in Brihat Trayi

Every diagnosis and formulation administered at Art of Ayurveda originates from the three authoritative Sanskrit medical treatises:

चरकसंहिता (Charaka Samhita)

Father of Internal Medicine

Codified by Maharshi Charaka, focusing on Jatharagni (digestive fire), Dhatus, Tridosha pathology, Kaya Chikitsa, and Rasayana longevity protocols.

सुश्रुतसंहिता (Sushruta Samhita)

Father of Surgery (Shalya Tantra)

Codified by Acharya Sushruta, detailing 121+ surgical instruments, plastic surgery, Kshara Sutra ligation, Agnikarma, and anatomy of Marma points.

अष्टाङ्गहृदयम् (Ashtanga Hridaya)

The Heart of 8 Branches

Authored by Vagbhata, distilling the clinical mastery of Charaka and Sushruta into rhythmic poetic shlokas uniting all eight faculties seamlessly.
