Delving into the ancient roots of Indian medicine reveals a rich tapestry of knowledge and insights into the study of anatomy. The Vedic philosophies laid the foundation for Ayurvedic medicine, one of the oldest known systems of healthcare. Within this tradition, the Sushruta Samhita and the Charaka Samhita are two foundational texts that provide valuable insights into the understanding of anatomy in ancient India. Through a combination of animal sacrifice, chance observations of improperly buried human bodies, and patient examinations, ancient Indian physicians pieced together a remarkable understanding of human morphology. In this article, we explore the fascinating journey of anatomical knowledge in ancient India, with a focus on the contributions of Shushruta and Charaka.
Unravelling the Tapestry of Ancient Indian Medicine
The study of medicine and human anatomy has deep roots in ancient civilizations such as Greece, Mesopotamia, Egypt, China, and India. India, as one of the oldest civilizations, has made significant contributions to the field of medicine, particularly in the realm of anatomy. The development of medicine in ancient India can be divided into three distinct periods: the Vedic period (c. 1500-500 BCE), the Brahmanic period (600 BCE-1000 CE), and the Mughal period (1000 CE until the 18th century) (Persaud, 1997). The ancient Indian name for the “science” of medicine is Ayurveda, which translates to the “Veda for the span of life.” Ayurveda, considered one of the oldest known systems of medicine, is based on the Vedic philosophies and was compiled during the Vedic period (Bhagvat Sing Jee, 1978).
The Ayurveda tradition finds its foundation in two essential texts: the Sushruta Samhita and the Charaka Samhita. These texts offer valuable insights into ancient Indian anatomical knowledge and surgical techniques. The Sushruta Samhita, written by the renowned physician and surgeon Sushruta in the 6th century BCE, provides detailed information on surgical procedures and anatomical understanding (Persaud, 1984). On the other hand, the Charaka Samhita, associated with the mid-2nd century, offers a broader perspective on medicine, including philosophical and ethical considerations (Porter, 1998). These texts, written in Sanskrit, formed the foundation of Ayurvedic education and were accessible only to direct disciples of the respective Gurus or schools (Nagaratnam, 1989).
Sushruta: The Father of Indian Surgery
Sushruta, often hailed as the father of Indian surgery, revolutionized the field with his groundbreaking work and contributions. While the exact timeline of his life remains a subject of debate among medical historians, Sushruta’s influence is unquestionable. His most famous work, the Sushruta Samhita, serves as a testament to his surgical prowess and anatomical knowledge. Although the original text has not survived, revisions and copies provide invaluable insights into his teachings (Ruthkow, 1961).
One of Sushruta’s notable achievements was the practice of rhinoplasty, a surgical procedure for reconstructing the nose. This pioneering technique was performed in India long before it gained recognition in other parts of the world. Sushruta’s knowledge of human anatomy was extensive, as evidenced by his emphasis on dissection and his understanding of the body’s structure and function (Hoernle, 1907; Keswani, 1970).
In ancient India, religious beliefs and laws posed significant obstacles to the study of anatomy. Hindu tenets deemed the human body sacred, forbidding its violation by the knife. However, Sushruta ingeniously circumvented these restrictions by using a brush-like broom to scrape off skin and flesh from corpses, allowing him to study anatomy without directly touching the bodies (Ruthkow, 1961). His meticulous observations of anatomical specimens led to the identification of over 300 bones, various joints, ligaments, and muscles, surpassing the knowledge of his time (Hoernle, 1907; Persaud, 1997).
The Sushruta Samhita: A Treasure Trove of Surgical Wisdom
The Sushruta Samhita stands as an enduring testament to Sushruta’s surgical expertise and anatomical understanding. Its literal translation, “that which is well heard” or “one who has thoroughly learned by hearing,” reflects the oral tradition of knowledge transmission prevalent at the time (Chari, 2003). The first translation of this ancient text from Sanskrit was in the 8th century, later followed by translations into Arabic, Latin, German, and English (Mukhopadhaya, 1929).
The Sushruta Samhita consists of two parts: the Purva-tantra and the Uttara-tantra. The Purva-tantra is further divided into five books: Sutrasthana, Nidana, Sarirasthana, Chikitsasthanam, and Kalpasthanam, containing a total of 120 chapters (Mukhopadhaya, 1929). During the time of the Sushruta Samhita, the healing arts were divided into five categories: physicians (Rogaharas), surgeons (Shaylyaharas), poison healers (Vishaharas), demon doctors (Krityaharas), and magic doctors (Bhisagatharvans) (Chari, 2003).
Journey Into the Anatomical Realm: Insights from the Sushruta Samhita
Recognizing the importance of anatomical knowledge for aspiring surgeons, Sushruta emphasized the study of human anatomy in the Sarirasthana, a section dedicated to the subject. In this section, Sushruta articulated the necessity for a deep understanding of anatomy to be a skilled and erudite surgeon (Singhal & Guru, 1973).
Sushruta’s words echo through time:
“The different parts or members of the body as mentioned before including the skin cannot be correctly described by one who is not well versed in anatomy. Hence, anyone desirous of acquiring a thorough knowledge of anatomy should prepare a dead body and carefully observe, by dissecting it, and examine its different parts” (Chattopadhyaya, 1933).
To overcome the religious restrictions on human dissection, Sushruta developed a meticulous method for dissection preparation. A cadaver meeting specific criteria, including the absence of chronic disease, age above 2 years, and removal of intestinal contents, was selected. The cadaver was wrapped in materials like bush or grass, bark, kusa, or flax and placed in a flowing river for decomposition. After seven nights, the decomposed cadaver was carefully dissected using brushes made from fragrant roots, hair, bamboo, or coarse grass. This method allowed for the comprehensive examination of the skin, internal and external parts, and subdivisions of the body (Singhal & Guru, 1973).
Unveiling the Mysteries of the Head and Neck
The Sushruta Samhita provides intriguing insights into surgical procedures and anatomical knowledge related to the head and neck. Ancient Hindu laws prescribed the cutting of the nose as a punishment for adultery (Persaud, 1997). Sushruta, demonstrating his understanding of facial anatomy, described a procedure for repairing severed or clipped noses. This reconstructive technique can be likened to modern “free flap” procedures used in reconstructive surgery (Mahabir, 2001).
Sushruta’s words elucidate the procedure:
“First, gather a leaf of a creeper broad enough to cover the severed part of the nose. Slice off a patch of living flesh from the cheek and scarify it before swiftly attaching it to the severed nose. Secure the adhesion with a bandage and insert two small pipes into the nostrils for respiration. After ensuring full adhesion, dust the adhered part with hemostatic powders and envelop the nose in cotton soaked in refined sesame oil” (Mahabir, 2001).
Another fascinating insight from the Sushruta Samhita involves the reconstruction of torn earlobes resulting from the widespread practice of enlarging ear piercings. Sushruta proposed a pedicle flap reconstructive procedure, involving the grafting of skin from adjacent areas while preserving its vascular supply. This technique allowed for the restoration of torn earlobes (Das, 1983).
“A surgeon well versed in the knowledge of surgery should slice off a patch of living flesh from the cheek and attach it to the former seat of the earlobe. The flap should be covered with honey and butter, bandaged with cotton and linen, and dusted with the power of baking clay” (Das, 1983).
Illuminating the Depths of Ophthalmic Knowledge
Sushruta’s understanding of ophthalmology shines through in the Sushruta Samhita, where he delves into the intricacies of eye anatomy and surgical techniques. Cataracts, a common ailment in ancient India, received considerable attention in his work. Sushruta described the eye as composed of five basic elements: earth (Bhu), fire/heat (Agni), air (Vayu), fluid (Jala), and void (Akasa). Each element corresponded to specific anatomical structures within the eye (Raju, 2003).
The Sushruta Samhita presents a comprehensive procedure for cataract removal:
“This procedure is auspiciously performed primarily in the warm season. The patient is prepared by rubbing the skin with an oily medicine and taking a heated bath. The sick room is fumigated to rid it of insects and diseases. Sedation is achieved using incense and wine. During the procedure, the patient focuses on their own nose while the surgeon pierces the eye at specific points. The anterior capsule of the lens is incised, and lens material is removed. Postoperatively, indigenous roots, leaves, and ghee are applied to the eye, and the patient is advised to rest and avoid sneezing or coughing” (Raju, 2003).
Unraveling the Mysteries of the Pelvis and Perineum
Ancient Indian medicine placed great importance on reproductive health and sexual energy. The Sushruta Samhita offers insights into male urogenital issues and the management of urethral strictures. Sushruta advocated for the use of dilators and surgical procedures to address these conditions (Das, 1983).
“In the case of Niruddhaprakasha (stricture of the urethra), a tube made of iron, wood, or shellac should be lubricated with clarified butter and gently introduced into the urethra. Thicker and thicker tubes should be used for dilation, and emollient food should be given to the patient. Alternatively, an incision can be made into the lower part of the penis as an incidental ulcer” (Das, 1983).
Conclusion: Unveiling the Legacy of Shushruta and Charaka
The contributions of ancient Indian physicians, particularly Shushruta and Charaka, to the field of medicine and the understanding of human anatomy are unparalleled. Through their pioneering work, the Sushruta Samhita and the Charaka Samhita, they laid the foundation for Ayurvedic medicine, a system still widely practiced today. Despite the religious and cultural constraints they faced, these visionary scholars utilized innovative methods and meticulous observations to unravel the secrets of human anatomy. Their teachings continue to inspire and inform modern medical practices, reminding us of the timeless wisdom that lies within the ancient texts of Indian medicine.
