History of Medicine

In my previous post, I explored the history of cancer. Since we know it existed in ancient times, it follows that so did its name. In fact, the name "cancer" was coined by none other than the great Hippocrates (well, not the exact name but the root of the name). Hippocrates in fact, used two terms,  carcinoma and carcinos,  to describe ulcerous and non-ulcerous tumors respectively. He named the tumors after Carcinus (or Karkinos), a giant crab in Greek mythology that was sent by the Goddess Hera to help Hydra fight against Hercules. As to why Hippocrates chose to name the tumor after a crab is not quite clear but there are several theories:       -  The hardness of a malignant tumor reminded him of the hard shell of a crab.      - The pain induced by a malignant tumor is similar to a sharp pinch of a crab's claw.     -  The tenacity of cancer is similar to the determination with which a crab bites and grabs on to a person.  While all these theories seem plausible, the

Welcome to Fall! Today, the autumn equinox marks the beginning of fall, my favorite season of all! “Equinox” of course means equal night in Latin and marks the day when the sun shines directly on the equator and both poles are equidistant from the sun, making day and night of equal length. It is also a point of balance between changing seasons, and between feminine and masculine energies. Position of earth relative to sun  It held special significance in ancient times as many societies celebrated it as a festival of harvest. In Greek mythology, the fall equinox marks the return of the goddess Persephone to the underworld to reunite with her husband Hades, king of the underworld (who incidentally abducted her after falling in love with her). Although she was rescued by her father, Zeus, she chooses to go back to Hades for six months every year during autumn and winter. Her mother, Demeter, who is the Goddess of agriculture and fertility, mourns her loss by making the earth infertile dur

Although western medicine has its roots in the Classical Greek civilization, the history of medicine dates back thousands of years before Classical Greece. Medicine started developing as a science in the earliest human civilizations and developed independently in all four of the major ancient civilizations: • Babylon/Mesopotamia • Egypt • India • China They represent four of the oldest branches of medicine with each developing independently and presumably without any interaction or influence from each other. And yet, they have many similarities. Ancient medicine in (clockwise from top left) Babylon, Egypt, China, and India  Babylon Babylonians believed that diseases were caused by supernatural forces (gods and demons) and therefore, did not distinguish between magic and medicine, yet they introduced the practice of diagnosis and prognosis. Treatment included identifying the illness according to the power that caused it, and treating it with medical agents and rituals to appease t

As I ponder a career in medicine, I have started researching colleges with good medical programs, which made me curious about medical schools in the past. Although the art of medicine was widely practiced in ancient civilizations, it wasn't really taught as a science until much later. It was only during the Classical period that medical schools started being established as a formal place to study the science of medicine.  The first known medical school was built in Alexandria around 311 BCE in modern-day Egypt (which was controlled by the Greeks at the time). However, Pergamum (where Hippocrates practiced) is rumored to have had a medical school earlier than that but there is very little known about this school, so the first medical school is credited to Alexandria. The Greeks were always stronger in medicine than the Romans, and Alexandria was certainly proof of that! What is also impressive is that Alexandria School of Medicine united all the different medical doctrines including

Following up on the history of essential oils seemed like a natural step, so here's a look at the origins of aromatherapy and essential oils. The birth of aromatherapy is generally attributed to Ancient Egypt, but the idea of using natural oils for medicinal purposes didn't just come from Egypt. Ancient Indians and Chinese also explored natural oils extensively, and it became an integral part of Indian Ayurvedic medicine.  The Egyptians used oils for many different purposes including religious ceremonies, cosmetics, medicine and even mummification. During mummification, embalmers used various botanicals like cinnamon, frankincense and myrrh, along with cedar and juniper oils to prepare the body for burial. They also left jars of essential oils in the tombs, presumably for the deceased to enjoy in the afterlife! Aromatic oils were extensively used for prayers, with each God having a different oil dedicated to them. The Egyptians cultivated plants specifically for their oils and

For my birthday recently, I got a gift certificate for a spa treatment, which I am really excited about. It is so relaxing and rejuvenating to both the body and the mind. I have also recently started using an oil diffuser in my room, and I absolutely love it!. It leaves my room smelling so fresh and natural, and feels so relaxing. It got me interested in aromatherapy and I found this cool book on using essential oils for different ailments called  Introducing Essential Oils: Ancient Medicine  by Dr. Josh Axe and others.  As you might guess from the title, the book not only describes the uses for different natural oils but also details how such oils have been used for healing through the ages, including during ancient Egyptian, Chinese, Greek, and Biblical times. They are still popular in many parts of the world and are slowly but surely gaining popularity here in the U.S.  Using aromatherapy for relaxation has been used for thousands of years, and its effectiveness is no myth- accordin

Continuing with the theme of ancient medicine being used for treating COVID-19,  a recent article claims that a 3000 year old medicine, derived from the autumn flower crocus, was recently found to show promising results for the treatment of the disease. Autumn crocus flowers The medicine, colchicine, has been used for many centuries as an anti-inflammatory agent for gout and arthritis. It was first mentioned as far back as 1500 BCE in the Egyptian manuscript, the Ebers Papyrus as a remedy for joint pain. It was derived from the autumn flower crocus, and widely used by the 1st century AD for gout and edema. In fact, it is said Benjamin Franklin, who suffered from edema, imported crocus plants to North America from France. The Ebers Papyrus. Image: National Institute of Health After the active ingredient was isolated in the 1800s, colchicine is now available in the form of a pill for various ailments such as gout and periciditis. Now, a team of Greek doctors conduct

Even though Cajal is considered the father of neuroscience, his contribution came centuries after the first insights into the nervous system. As I wrote in my earlier posts, ancient doctors pondered over the nervous system, trying to understand what controlled the mind and body. Of these doctors, one that stands out is Galen, whose contribution to the understanding of the nervous system was fundamental to neuroscience. Through anatomical experiments, Galen was the first to observe and teach the functioning of nerves in the body. For these experiments, which he wasn’t shy about demonstrating to the public, Galen is regarded as the founder of experimental physiology. Galen is considered one of the most prominent and influential doctors in history, second only to Hippocrates. Galen was a staunch follower of Hippocrates and helped spread his teachings from Greece to the vast Roman Empire. Claudius Galenus, commonly know as Galen, was born in 129 AD in Pergamum in modern-day Turkey to a

As I wrote in my last post, Hippocrates was the first physician to recognize the brain as the center of conscience and intelligence. Until then, it was widely believed that the heart controlled all emotions and intellect. This theory came from the ancient Egyptians who maintained that the heart was the seat of thought and soul, and the brain was nothing more than an accessory. They believed that good deeds lightened the heart, so when one died, the God Ammut would weigh the heart and decide your fate depending on the weight. A heart that was as light as a feather was returned to life, but a heavy heart was gobbled up. It seems that this is the reason we correlate happiness and kindness with a light heart and grief with a heavy heart! God Ammut weighing a dead man's heart in the afterlife. Image: National Geographic The ancient Greeks had opposing views on the center of thought and emotions. Aristotle was one of the most famous proponents of the Egyptian theory that the hear

This summer, I am taking a course in neuroscience at Harvard Summer School. I am super excited about this course because I have always wanted to learn about neuroscience, and who can argue about taking a course at Harvard? The study of the brain is such a fascinating subject, and I have always wanted to learn more about it. Since I am the only left-handed person in my immediate family, it has always intrigued me to learn that right and left-handedness is controlled by different sides of the brain. So my brain functions differently than everyone else in my family! At least that's what I understand. I hope to confirm this and a lot more when I actually take the class. The brain is hands down the most complex organ of the human body. It controls so many functions- motor skills, memory, emotions to name just a few. It's no wonder it has intrigued men since the ancient times, as early as the Greeks and Hippocrates himself. In fact, it is often said that the birth of neuroscienc

Another important person in Greek medicine is Hippocrates. Hippocrates is considered the father of modern medicine who continues to influence medicine more than 2000 years later. Although he is as revered as Asclepius, they have very different origins. While Asclepius is a mythological character, considered to be descended from God, Hippocrates is very much a historical figure, whose origin and life is recorded in history. Hippocrates lived from 460 to 375 BCE during the Classical Greece period and practiced medicine in Greece. His contribution to western medicine is rivaled by none other, and his collection of works covers almost every aspect of disease and medicine including infection, hygiene, epidemiology and the human immune system. Bust of Hippocrates Also, unlike Asclepius, Hippocrates practiced medicine as a science, not as divine magic. He was one of the first to separate religion from medicine, and sought to match treatment with symptoms.  His observations in the Corp

Asclepius is the ancient Greek god of medicine. He is the son of Apollo and a mortal woman named Koronis, which makes him a demigod. Asclepius grew up motherless with different versions of how he lost his mother. However, in all versions of his story, he is brought up by his father, Apollo, who grants him the gift of healing and the secrets of medicine using herbs and plants. Asclepius is married to Hygeia, the goddess of hygiene and health (although some versions claim she is his daughter!) Statue of Asclepius Asclepius was a very gifted healer who was so successful at saving lives that he could also raise the dead. This made the god of the underworld, Hades, worried that he would not get any dead spirits, so he complained to his brother, Zeus. Fearing that Asclepius will make humans immortal, Zeus kills Asclepius with the strike of a thunderbolt, but later places him among the stars as the constellation, Ophiuchus , also known as the Serpent bearer. Ophiuchus constella

When watching news about the WHO (World Health Organization), I noticed their flag has a serpent coiled around a rod, which bears resemblance to many other medical logos. Asclepius, the Greek god of medicine, is also always depicted with a staff entwined with a serpent, so it piqued my interest about the origin of the medical symbols containing a serpent and a stick. It was hardly surprising when I found that many logos associated with modern medicine are actually derived from the Rod of Asclepius. WHO emblem Statue of Asclepius with the Rod of Asclepius The snake was used as a symbol of healing by the ancient Greeks because snakes were regarded as sacred and used in healing rituals. The venom from snakes was considered remedial and used for many ailments. Also, the shedding of the snake’s skin was viewed as a symbol of rebirth and renewal. Several healing temples or asclepieia where the sick were sent to recuperate in ancient Greece had non-venomous snakes called the

The coronavirus pandemic has brought a fresh focus on personal habits; we all know the drill by now: wash hands with soap for 20 seconds, use hand sanitizer containing at least 60% alcohol and do not touch your face. These simple habits go a long way in protecting us from not just covid-19 but any infectious disease (something to remember next flu season!). Although it helps to be reminded, most people know the value of personal hygiene and its effect on health. Infectious diseases were common in ancient times, and although the cause of such diseases was not well understood, the concept of hygiene was certainly associated with health. The word hygiene itself derives from Hygieia, the Greek goddess of health and cleanliness, who was the daughter of Asclepius, the god of medicine. Statue of Hygieia. Image: Greek Mythology The Greeks had the theory of miasma that attributed diseases to bad air, which was really a primitive concept of hygiene. Hippocrates himself recommended patie

Coronavirus has become a household name after the current COVID-19 outbreak. The virus has been identified as a positive sense single-stranded RNA virus and has the technical name, SARS-CoV2. It is also well known that it is highly contagious and is transmitted between humans through coughing and sneezing via respiratory droplets. Scientists have a pretty good understanding of what causes the COVID-19 disease and how it spreads through the population, which makes it easier for people to understand the concept and purpose of social distancing and quarantine. But in ancient times, ideas about the cause of diseases were entirely speculative and there were many interesting theories before the germ theory of diseases was established in the late 1800s. Supernatural Theory Unsurprisingly, the earliest theory was that diseases were caused by supernatural forces. People believed that when gods became angry they unleased their fury upon mankind by sending diseases to cause suffering. For ex

As the world learns a new way of life involving self-isolation amid the global spread of coronavirus, the concept of quarantine has been brought to the forefront. According to Merriam-Webster dictionary, quarantine means “to put or hold in isolation to prevent the spread of disease” and that is exactly what we are experiencing right now. Many countries and several states in the U.S. have imposed mandatory isolation of its population to curb the spread of the coronavirus. Although the mass quarantine imposed today might be unprecedented in history, quarantine is certainly not a new concept. The word itself is derived from "quaranta giorni", which in Italian means 40 days. It originated sometime in the mid-14th century, when all ships coming into Venice were isolated before passengers and crew were allowed to disembark during the Black Death plague epidemic. However, the practice of quarantine dates further back, all the way to ancient times. Ancient Greeks were isolating si

Sticking with the wonderful theme of alcohol, here’s a look at wine in ancient medicine. Adapted again from  Tom Standage’s A History of the World in 6 Glasses , but also other sources that have studied the use of wine in ancient civilizations. Although beer is thought to be the oldest drink consumed by humans, wine has an equally ancient history. The only difference is that it took longer for wine to become a common drink. The origin of wine has been traced back to the Neolithic Period, somewhere between 9000 and 4000 BCE, in the Zagros Mountains in present-day Iran and Armenia. Unlike beer, which was drunk by both the rich and the poor, wine was a status symbol associated with wealth and power. It was only consumed by those who could afford the expensive beverage, namely kings and noble men in ancient Greece. It was the Romans who transformed it from a luxury drink to one for the masses. It has been well known since the time of the ancient Greeks that wine can help relax and re

As the possibility of a major coronavirus outbreak in the U.S. turns to reality, I figured it would be useful to do more research into the history and evolution of the family of viruses that coronavirus belongs to— influenza. One of the oldest diseases in mankind’s history dating back 2400 years, the flu is caused by the influenza virus, which was isolated only in the 1930s after the  1918 Spanish flu, the  biggest flu pandemic in history. This pandemic killed over half a million people in the United States and around 50 million (some estimates are as high as 100 million) worldwide. The Spanish flu had a mortality rate between 2-20% and it lowered the average life expectancy of the American population by more than 12 years. Compared to that flu outbreak, the current coronavirus pandemic pales in significance, surely thanks to our current knowledge of epidemiology and the proactive measures taken by governments to curb the spread of the virus, rather than any change in the lethal nature
