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.
अष्टावङ्गानि तस्याहुश्चिकित्सा येषु संश्रिता ॥
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 MedicineCodified 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.
