Medical and healing practices in early Chinese dynasties were heavily shaped by the practice of traditional Chinese medicine (TCM). Starting around the Zhou dynasty, parts of this system were being developed and are demonstrated in early writings on herbs in Classic of Changes (Yi Jing) and Classic of Poetry (Shi Jing).
China also developed a large body of traditional medicine. Much of the philosophy of traditional Chinese medicine derived from empirical observations of disease and illness by Taoist physicians and reflects the classical Chinese belief that individual human experiences express causative principles effective in the environment at all scales. These causative principles, whether material, essential, or mystical, correlate as the expression of the natural order of the universe.
The foundational text of Chinese medicine is the Huangdi Neijing, (or Yellow Emperor's Inner Canon), written 5th century to 3rd century BCE. Near the end of the 2nd century CE, during the Han dynasty, Zhang Zhongjing, wrote a Treatise on Cold Damage, which contains the earliest known reference to the Neijing Suwen. The Jin dynasty practitioner and advocate of acupuncture and moxibustion, Huangfu Mi (215–282), also quotes the Yellow Emperor in his Jiayi jing, c. 265. During the Tang dynasty, the Suwen was expanded and revised and is now the best extant representation of the foundational roots of traditional Chinese medicine. Traditional Chinese medicine that is based on the use of herbal medicine, acupuncture, massage and other forms of therapy has been practiced in China for thousands of years.
Critics say that TCM theory and practice have no basis in modern science, and TCM practitioners do not agree on what diagnosis and treatments should be used for any given person. A 2007 editorial in the journal Nature wrote that TCM "remains poorly researched and supported, and most of its treatments have no logical mechanism of action." It also described TCM as "fraught with pseudoscience".  A review of the literature in 2008 found that scientists are "still unable to find a shred of evidence" according to standards of science-based medicine for traditional Chinese concepts such as qi, meridians, and acupuncture points, and that the traditional principles of acupuncture are deeply flawed. There are concerns over a number of potentially toxic plants, animal parts, and mineral Chinese compounds, as well as the facilitation of disease. Trafficked and farm-raised animals used in TCM are a source of several fatal zoonotic diseases. There are additional concerns over the illegal trade and transport of endangered species including rhinoceroses and tigers, and the welfare of specially farmed animals, including bears.

=== Ancient Indian medicine ===

The Atharvaveda, a sacred text of Hinduism dating from the middle Vedic age (c. 1200–900 BCE), is one of the first Indian texts dealing with medicine. It is a text filled with magical charms, spells, and incantations used for various purposes, such as protection against demons, rekindling love, ensuring childbirth, and achieving success in battle, trade, and even gambling. It also includes numerous charms aimed at curing diseases and several remedies from medicinal herbs, overall making it a key source of medical knowledge during the Vedic period. The use of herbs to treat ailments would later form a large part of Ayurveda.
Ayurveda, meaning the "complete knowledge for long life" is another medical system of India. Its two most famous texts (samhitas) belong to the schools of Charaka and Sushruta. The Samhitas represent later revised versions (recensions) of their original works. The earliest foundations of Ayurveda were built on a synthesis of traditional herbal practices together with a massive addition of theoretical conceptualizations, new nosologies and new therapies dating from about 600 BCE onwards, and coming out of the communities of thinkers which included the Buddha and others.
According to the compendium of Charaka, the Charakasamhitā, health and disease are not predetermined and life may be prolonged by human effort. The compendium of Sushruta, the Sushruta Samhita, defines the purpose of medicine to cure the diseases of the sick, protect the healthy, and to prolong life. Both these ancient compendia include details of the examination, diagnosis, treatment, and prognosis of numerous ailments. The Sushruta Samhita is notable for describing procedures on forms of surgery, including rhinoplasty, the repair of torn ear lobes, perineal lithotomy, cataract surgery, and other excisions and surgical procedures. Susruta also described more than 125 surgical instruments in detail. Sushruta had a penchant for scientific classification: his medical treatise consists of 184 chapters, 1,120 conditions are listed, including injuries and illnesses relating to aging and mental illness.
The Ayurvedic classics mention eight branches of medicine: kāyācikitsā (internal medicine), śalyacikitsā (surgery including anatomy), śālākyacikitsā (eye, ear, nose, and throat diseases), kaumārabhṛtya (pediatrics with obstetrics and gynaecology), bhūtavidyā (spirit and psychiatric medicine), agada tantra (toxicology with treatments of stings and bites), rasāyana (science of rejuvenation), and vājīkaraṇa (aphrodisiac and fertility). Apart from learning these, the student of Āyurveda was expected to know ten arts that were indispensable in the preparation and application of his medicines: distillation, operative skills, cooking, horticulture, metallurgy, sugar manufacture, pharmacy, analysis and separation of minerals, compounding of metals, and preparation of alkalis. The teaching of various subjects was done during the instruction of relevant clinical subjects. For example, the teaching of anatomy was a part of the teaching of surgery, embryology was a part of training in pediatrics and obstetrics, and the knowledge of physiology and pathology was interwoven in the teaching of all the clinical disciplines.
Even today Ayurvedic treatment is practiced, but it is considered pseudoscientific, some ayurvedic medicines have been found to contain toxic substances. Both the lack of scientific soundness in the theoretical foundations of ayurveda and the quality of research have been criticized.
