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.
Unfortunately in the 17th century medicine was still handicapped by wrong ideas about the human body. Most doctors still thought that there were four fluids or 'humors' in the body, blood, phlegm, yellow bile and black bile. Illness resulted when you had too much of one humor. Nevertheless during the 17th century a more scientific approach to medicine emerged and some doctors began to question traditional ideas. Apart from Harvey the most famous English doctor of the 17th century was Thomas Sydenham (1624-1689). He is sometimes called the English Hippocrates because he emphasized the importance of carefully observing patients and their symptoms.
But there are less obvious ways in which evolutionary principles apply to infectious diseases. It has been known for a long time that sickle-cell trait provides resistance to malaria (the blood cells are less hospitable to the P. falciparum protozoan parasite that is one cause of malaria). This explains the persistence of sickle cell disease in populations where malaria is endemic.
1867 Joseph Lister publishes Antiseptic Principle of the Practice of Surgery, one of the most important developments in medicine. Lister was convinced of the need for cleanliness in the operating room, a revolutionary idea at the time. He develops antiseptic surgical methods, using carbolic acid to clean wounds and surgical instruments. The immediate success of his methods leads to general adoption. In one hospital that adopts his methods, deaths from infection decrease from nearly 60% to just 4%.

A nearby tomb reveals the image of Merit Ptah, the first female doctor known by name. She lived in approximately 2,700 BC and hieroglyphs on the tomb describe her as ‘the Chief Physician’. That’s pretty much all that’s known about her career, but the inscription reveals that it was possible for women to hold high-status medical roles in Ancient Egypt.
Due to the hot and dry climate in Egypt, ancient papyri have survived intact, allowing historians to study the sophisticated techniques employed by Ancient Egyptian physicians. Whilst couched in magic and ritual, the Egyptians possessed a great deal of knowledge of healing herbs and repairing physical injuries, amongst the normal population and the workers responsible for building the great monuments of that nation.
Scientists, led by Deborah Hung in the HMS Department of Microbiology and Immunobiology and at Mass General and Brigham and Women’s, show that a detailed RNA signature of specific pathogens can identify a broad spectrum of infectious agents, forming the basis of a diagnostic platform to earlier determine the best treatment option for infectious diseases.

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, 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. The normal length of the student's training appears to have been seven years. But the physician was to continue to learn.

In the Middle Ages monasteries had sanitation. Streams provided clean water. Dirty water was used to clear toilets, which were in a separate room. Monks also had a room called a laver where they washed their hands before meals. However for most people sanitation was non-existent. In castles the toilet was simply a long passage built into the thickness of the walls. Often it emptied into the castle moat. Despite the lack of public health many towns had public bath-houses were you could pay to have a bath.
James Maskell: Dr. Larry Palevsky is speaking, and he’s speaking on the pediatrics day. He’s an awesome doctor. He was lecturing about the microbiome five years ago, before the human microbiome came out. And so I asked him, he spoke at my Functional Forum, and he brought up some concepts that were new, and I was sitting next to storied integrative medicine doctors who were just sort of blown away. And his thought is this: We all know now that 99% of our bacteria and fungus and viruses and so forth are mutually beneficial, and they help us, and they help with metabolism and digestion and immunity. That’s our sort of main understanding. So I asked him, “Dr. Palevsky, what are we going to learn next? What are we really going to understand next about the microbiome that we don’t understand now?” And he basically—you have to listen to it on the summit, but he basically says this—“We have trillions of non-redundant viruses in our chromosomes, in our DNA. So these are trillions of viruses that we’ve evolved with over time.” And so his question is, “When you get a viral illness, how many more viruses have to come into the body for you to get a viral illness? 10? 20? 100?” I mean, when you look at the numbers compared to what’s actually in our chromosomes and in our DNA, the numbers just don’t add up. His thought is, and his concept is, that these viruses, there’s different transmission mechanisms. His thought is that the next understanding that we’re going to have of the microbiome, the next level of understanding is going to be that the body and these viruses work together to be able to return the body to homeostasis. So when you get to a point where the body is just so stressed and there’s too many toxins and things for it to deal with, and it can’t get back to homeostasis by itself, it communes with viruses to be able to instigate what we think of as a viral illness, to be able to get the patient to just slow down, so that we can get back to homeostasis. And it made such an impression on me because I had a friend last year who got viral pneumonia. And what was happening before viral pneumonia? She was working for three months on a project about 15 hours a day. And suddenly, it finished and she did great with it, and then she was sick for a month with viral pneumonia. So what, pneumonia just came along and attacked at that moment? Obviously, not. So I’d love to get your thoughts on that. Because when he shared that, I was like, “This seems so obvious.” And I’m really excited to think what our understanding is going to be like when we start to appreciate that our evolution with viruses is a big part of our evolution, and that there may be a lot more to it than thinking a virus is just something that comes from outside all the time.
The means of dressing the incision was also highly developed: the surgeon used seven polished iron spikes to bring the edges of the wound together, tying them in place with bark-cloth string. He then applied a thick layer of herbal paste and covered this with a warm banana leaf held in place with a bandage. According to Felkin’s account, the mother and her baby were still doing well when he left the village 11 days later.
The Islamic civilization rose to primacy in medical science as its physicians contributed significantly to the field of medicine, including anatomy, ophthalmology, pharmacology, pharmacy, physiology, surgery, and the pharmaceutical sciences. The Arabs were influenced by ancient Indian, Persian, Greek, Roman and Byzantine medical practices, and helped them develop further. Galen & Hippocrates were pre-eminent authorities. The translation of 129 of Galen's works into Arabic by the Nestorian Christian Hunayn ibn Ishaq and his assistants, and in particular Galen's insistence on a rational systematic approach to medicine, set the template for Islamic medicine, which rapidly spread throughout the Arab Empire. while Europe was in its Dark Ages, Islam expanded in West Asia and enjoyed a golden age. Its most famous physicians included the Persian polymaths Muhammad ibn Zakariya al-Razi and Avicenna, who wrote more than 40 works on health, medicine, and well-being. Taking leads from Greece and Rome, Islamic scholars kept both the art and science of medicine alive and moving forward.

After the fall of Rome in the 5th century the eastern half of the Roman Empire continued (we know it as The Byzantine Empire) and later Muslims took their knowledge of medicine from there. In the 9th century a man named Hunain Ibn Ishaq traveled to Greece collecting Greek books. He then returned to Baghdad and translated them into Arabic. Later the same works were translated into Latin and passed back to western Europe.
In the Eastern Empire, based on Byzantium, physicians kept the knowledge and the skills passed from the Romans and the Greeks. This knowledge would form the basis of the Islamic medicine that would refine and improve medial techniques during the Islamic domination of the Mediterranean and Middle East. The history of Medicine would center on the Middle East and Asia for the next few centuries.
In this episode, we followed on from last week's Functional Forum and talked about the role of education in the future of medicine, and particularly the role of delivery of content.

Another of Hippocrates's major contributions may be found in his descriptions of the symptomatology, physical findings, surgical treatment and prognosis of thoracic empyema, i.e. suppuration of the lining of the chest cavity. His teachings remain relevant to present-day students of pulmonary medicine and surgery. Hippocrates was the first documented person to practise cardiothoracic surgery, and his findings are still valid.
Being a king in ancient times was exhaustingly dangerous; there was always someone plotting to get rid of you. So, according to legend, Mithradates (aka Mithridates) VI of Pontus (on the shores of the Black Sea in Turkey) attempted to become resistant to poisons by taking gradually increasing doses. He was also reputed to have conducted toxicological experiments on condemned prisoners, culminating in the creation of mithridate – a medicine that combined all known antidotes in one potent formula.
1950s: A series of successful anti-psychotic drugs are introduced that do not cure psychosis but control its symptoms. The first of the anti-psychotics, the major class of drug used to treat psychosis, is discovered in France in 1952 and is named chlorpromazine (Thorazine). Studies show that 70 percent of patients with schizophrenia clearly improve on anti-psychotic drugs.
