The word "Ayurveda" is a tatpurusha compound of the word ayus meaning "life" or "life principle", and the word veda, which refers to a system of "knowledge".
Thus "Ayurveda" roughly translates as the "knowledge of life”
Ayurveda is also one among the few traditional systems of medicine to contain a sophisticated system of surgery Flow of Information : Flow of Information Lord Brahma DHAKSHA PRJAPATHI INDRA Chain of deities Bharadvaja

Spiritual Healing/Psychiatry - Bhuta Vidya The central concept of Ayurvedic medicine : The central concept of Ayurvedic medicine The central concept of Ayurvedic medicine is the theory that health exists when there is a balance between three fundamental bodily humours or doshas called Vata, Pitta and Kapha.
Vata is the impulse principle necessary to mobilize the function of the nervous system
Pitta is the energy principle which uses bile to direct digestion and hence metabolism into the venous system.
Kapha is the body fluid principle which relates to mucous, lubrication and the carrier of nutrients into the arterial system. Slide 8: Ayurveda , the science of life, prevention and longevity is the oldest and most holistic medical system available on the planet today.
It was placed in written form over 5,000 years ago in India, it was said to be a world medicine dealing with both body and the spirit. Slide 9: Before the advent of writing, the ancient wisdom of this healing system was a part of the spiritual tradition of the Sanatana Dharma (Universal Religion), or Vedic Religion.. Slide 10: Slide 11: VedaVyasa, the famous sage, shaktavesha avatar of Vishnu, put into writing the complete knowledge of Ayurveda, along with the more directly spiritual insights of self realization into a body of scriptural literature called the Vedas and the Vedic literatures Slide 12: There were originally four main books of spirituality, which included among other topics, health, astrology, spiritual business, government, army, poetry and spiritual living and behavior. Slide 13: These books are known as the four Vedas; Rik, Sama, Yajur and Atharva. The Rik Veda, a compilation of verse on the nature of existence, is the oldest surviving book of any Indo-European language (3000 B.C.). Slide 14: The Rik Veda (also known as Rig Veda) refers to the cosmology known as Sankhya which lies at the base of both Ayurveda and Yoga, contains verses on the nature of health and disease, pathogenesis and principles of treatment.
Among the Rik Veda are found discussions of the three dosas, Vayu. Pitta and Kapha, and the use of herbs to heal the diseases of the mind and body and to foster longevity. Slide 15: The Atharva Veda lists the eight divisions of Ayurveda: Internal Medicine, Surgery of Head and Neck, Opthamology and Otorinolaryngology, Surgery, Toxicology, Psychiatry, Pediatrics, Gerontology or Science of Rejuvenation, and the Science of Fertility. Slide 16: The Vedic Sages took the passages from the Vedic Scriptures relating to Ayurveda and compiled separate books dealing only with Ayurveda.
One of these books, called the Atreya Samhita is the oldest medical book in the world! The Vedic Brahmanas were not only priests performing religious rites and ceremonies, they also became Vaidyas (physicians of Ayurveda). Slide 17: The sage-physician-surgeons of the time were the same sages or seers, deeply devoted holy people, who saw health as an integral part of spiritual life. It is said that they received their training of
Ayurveda through direct cognition during meditation. In other words, the knowledge of the use of various methods of healing, prevention, longevity and surgery came through Divine revelation; there was no guessing or testing and harming animal. Slide 18: People from numerous countries came to Indian Ayurvedic schools to learn about this world medicine and the religious scriptures it sprang from. Learned men from China, Tibet, the Greeks, Romans, Egyptians, Afghanistanis, Persians, and more traveled to learn the complete wisdom and bring it back to their own countries. Slide 19: Ayurvedic texts were translated in Arabic and under physicians such as Avicenna and Razi Sempion, both of whom quoted Indian Ayurvedic texts, established Islamic medicine. This style became popular in Europe, and helped to form the foundation of the European tradition in medicine. Slide 20: In 16th Century Europe, Paracelsus, who is known as the father of modem Western medicine, practiced and propagated a system of medicine which borrowed heavily from Ayurveda. Slide 21: There are two main re-organizers of Ayurveda whose works are still existing in tact today - Charak and Sushrut. The third major treatise is called the Ashtanga Hridaya, which is a concise version of the works of Charak and Sushrut. Slide 22: Thus the three main Ayurvedic texts that are still used today are the Charak Samhita (compilation of the oldest book Atreya Samhita), Sushrut Samhita and the Ashtangha Hridaya Samhita. Slide 23: These books are believed to be over 1,200 years old. It is because these texts still contain the original and complete knowledge of this Ayurvedic world medicine, that Slide 24: Ayurveda is known today as the only complete medical system still in existence. Other forms of medicine from various cultures, although parallel are missing parts of the original information. Slide 25: "Life (ayu) is the combination (samyoga) of body, senses, mind and reincarnating soul. Ayurveda is the most sacred science of life, beneficial to humans both in this world and the world beyond."—Charaka Samhita, Sutrasthana, 1.42-43. Slide 26: The verses of Rig Veda, the earliest source of ayurveda, refer to panchamahabhut (five basic elements of the entire creation), and the three doshas or primary forces of prana or vata (air), agni or pitta (fire) and soma or kapha (water and earth) as comprising the basic principles of ayurveda. Slide 28: These five elements in different combinations constitute the three body types/doshas—vata dosha (air and ether), pitta dosha (fire) and kapha dosha (earth and water).
The panchamahabhut and the dosha theories are the guiding factors of ayurveda as a therapeutic science. The Rig Veda also mentions organ transplants and herbal remedies called soma with properties of elixir. Slide 29: The most fascinating aspect of ayurveda is, it was using almost all methods of healing like lifestyle regimen, yoga, aroma, meditation, gems, amulets, herbs, diet, jyotishi (astrology), color and surgery etc. in treating patients. Slide 30: Though ayurveda came into being as an independent upaveda of Atharva Veda, it has close links with other Vedas also. The Yajur Veda, which recommends rituals to pacify the panchamahabhuts in a view to heal both the Cosmic Being and the individual soul, is related to ayurveda in its principles and regulations of lifestyle. Slide 31: The upaveda called Dhanur Veda or the martial arts and ayurveda both refer to each other in the treatment of marmas or sensitive points in the body. Ayurveda recommends specific ayurvedic massages, exercises and bodywork for this purpose. Slide 32: Around 15,00 BC ayurveda was delineated into to two distinct schools: Atreya—The School of Physicians, and Dhanvantari—The School of Surgeons.
This made ayurveda a more systematically classified medical science, hereafter. Dhanvantari, who is considered to be a reincarnation of Lord Vishnu, was the guiding sage of ayurveda Slide 33: He made this science of health and longevity popular and widely acceptable. In fact, these two schools of thought led to the writing of two major books on ayurveda—Charaka Samhita and Susruta Samhit Slide 34: Approximately, during 4,000 to 3,000 BC, Sam Veda and Yajur Veda, the second and third Vedas came into being. Chanting of mantras and performance of rituals were, respectively, dealt in these two Vedas. And, during 3,000 to 2,000 BC Atharva the fourth Veda was authored, of which ayurveda is an upaveda (subsection). Slide 35: Though it had been practiced all along, it was around this time that Ayurveda in India, was codified from the oral tradition to book form, as an independent science Slide 36: It enlists eight branches/divisions of ayurveda:
Kayachikitsa (Internal Medicine),
Shalakya Tantra (surgery and treatment of head and neck, Ophthalmology and Otolaryngology),
Shalya Tantra (Surgery),
Agada Tantra (Toxicology), Slide 37: Bhuta Vidya (Psychiatry),
Rasayana (science of rejuvenation or anti-aging), and
Vajikarana (the science of fertility).
The oldest treatise available on this codified version is Atreya Samhita Slide 38: These two Samhitas were written in the early part of 1000 BC. The great sage- physician Charaka authored Charaka Samhita revising and supplementing the text written by Atreya, which has remained the most referred ayurvedic text on internal medicine till date. Slide 39: Susruta, following the Dhanvantari School of Thought, wrote Susruta Samhita, comprising the knowledge about prosthetic surgery to replace limbs, cosmetic surgery, caesarian operations and even brain surgery Slide 40: He is famed for his innovation of cosmetic surgery on nose or rhinoplasty. Around 500 AD, Vagbhatt compiled the third major treatise on ayurveda, Astanga Hridaya. It contained knowledge comprising the two schools of ayurveda. Slide 41: From 500 AD to 1900 AD, sixteen major Nighantus or supplementary texts on ayurveda like Dhanvantari Bhavaprakasha, Raja and Shaligram among others were written incorporating new drugs, Slide 42: expansion in applications, discarding of old drugs and identification of substitutes. These texts mention about 1814 varieties of plants in vogue. Slide 43: Charaka Samhita is considered to be the most ancient and authoritative writing on ayurveda available today. It also explains the logic and philosophy on which this system of medicine is based. Slide 44: The detailed biography of the composer of this treatise—that is, sage Charaka—is not known to the posterity. Interestingly, it is not an original writing of a single person rather like all Vedic knowledge it is a continuation and renewal of that ancient knowledge system Slide 45: According to Charaka, science is dependent upon yukti—a quality of the intellect that enables it to perceive phenomena brought into existence by a multiplicity of causes. Thus, it's not surprising that much of the treatise of Charaka Samhita is in the form of a symposium wherein groups of ayurvedic scholars take up a series of topics for discussion. Slide 46: This gives indication that the science of Ayurveda is a product of constant verification, fine-tuning and authentication by an active community of physicians. The samhita mentions about the gradual development of the fetus within the womb in minutes that equals the modern medical version in accuracy. Slide 47: The language is Sanskrit and is written in verse form. The style is in keeping with the Vedic oral tradition of conserving knowledge. The samhita contains 8,400 metrical verses. Slide 48: Charaka followed the Atreya School of Physicians, which predominantly deals with treatments through internal and external application of medicine. Though the samhita contains all the theoretical knowledge of Ayurveda it's focus is on healing the body, mind and soul of a patient in the minimum invasive manner that's Kayachikitsa. Slide 49: Hence, he placed great emphasis on the diagnostic part of the treatment. So much so that he classified everything from solar calendar to topography to the timing of the birth of a child.
He identified eight stages of a disease from its inception to the culmination. Charaka also laid great emphasis on the timing and manner of the collection of medicinal plants. Slide 50: Charaka sought to correct the element of fire or the digestive function in a body. It sought to alter the chemical processes in the cells by purification methods and medicinal application.
From a greater perspective Charaka laid emphasis for health and longevity to strike a balance between one's corporeal and spiritual being. That is the reason why Charaka went so detail into the diagnosis of a disease's origin Slide 51: Susruta wrote his samhita, the most authentic text on the practice of ayurvedic surgery around the sixth century BC Susruta is, also, renowned as the father of plastic surgery. He represents the Dhanvantari School of surgeons. Slide 52: His samhita discussed in minute details on how to perform prosthetic surgery to replace limbs, cosmetic surgery on nose and on other parts of the body, cesarean operations, setting of compound fractures, and even brain surgery.
Susruta's original work seems to have been revised and supplemented by Nagarjuna between the third and fourth centuries AD. Slide 53: This branch of medicine is believed to have arisen in part from the exigencies of dealing with the effects of war. Epic Ramayana, mentions remarkable feats of surgery having taken place in the past. We have reference to the transplantation of an eyeball and a head in epics. Slide 54: The style Susruta Samhita is both prose and poetry with poetry being the greater portion. This work, also, is said to be a redaction of oral material passed down verbally from generation to generation. Slide 55: This work is unique in that it discusses blood in terms of the fourth doshic principle. This work is the first to enumerate and discuss the pitta subtypes. Susruta details about 125 surgical instruments used by him mostly made of stones, wood and other such natural materials. The Susruta Samhita presents many innovations in Ayurvedic surgery. Slide 56: Use of shalaka—meaning foreign body (here, rods or a probe etc.) is mentioned by Susruta. Some of the classifications found in the Susruta Samhita are not even traced by the modern medical science. It described five types of pterygium, and the prognosis it made about glaucoma has not been improved since. In fact he is the first surgeon in medical history who systematically and elaborately dealt with anatomical structure of eye. Slide 57: The Susruta Samhita, besides being the most authentic text on practice and theory of surgery, is also the most commonly quoted text on health. Slide 58: Astanga Hridaya is accepted as the third major treatise on ayurveda. Around 500 AD, Vagbhatt compiled this samhita. It contained knowledge comprising the two schools of ayurveda—the school of surgery and the school of physicians. Slide 59: The Astanga Hridaya primarily deals with kayachikitsa besides, discussing in detail about various surgical treatments. The kapha subtypes are first listed and described in this samhita, completing exhaustive explanation of vata, pitta, kapha with their five subtypes. Slide 60: Astanga Hridaya seems to emphasize on the physiological aspect of the body rather than the spiritual aspects of it like its counterparts—Charaka and Susruta Samhitas. Despite that, the quality and range of its discussions about ayurveda makes it a work to reckon with.
