Our Planet, Our Health

For World Health Day 2022, the WHO has selected the theme, "Our Planet, Our Health", with the aim of creating a healthier world. WHO's statement reads,  "In the midst of a pandemic, a polluted planet, increasing diseases like cancer, asthma, heart disease, on World Health Day 2022, WHO will focus global attention on urgent actions needed to keep humans and the planet healthy and foster a movement to create societies focused on well-being." 


In the spirit of World Health Day, I wanted to explore the idea of health in ancient medicine. This is a topic that I have written on before but I thought it would be interesting to compare the ideology of good health in different societies of the ancient world.

Ancient Medicine

Across all ancient civilizations, before scientific thought became common, the prevailing idea was that 
good health was a divine gift, while poor health was attributed to divine punishment.

Theory of Spirits

Even though the ancient Egyptians were one of the first to impart medical treatment, the prevalent theory on health was that it was controlled by gods, demons, and spirits. It was believed that spirits blocked channels in the body which in turn affected the functioning of the organs.

Theory of Humors

In ancient Greek medicine, which was built on Hippocrates' teachings, good health was attributed to the balance of the four humors in the body:  blood, phlegm, yellow bile, and black bile. 

Theory of Consciousness and Doshas

According to Ayurveda, the ancient Indian medicine, disease is caused by an imbalance or stress in a person's consciousness; good health is achieved by a balance between the body, mind, spirit, and the environment. Health can also be impacted by an imbalance in the three doshas: vata, pitta and kapha.

Theory of Qi and Life Forces

Traditional Chinese Medicine (TCM) believes that good health is the result of a balance between the vital forces of life called Qi, which is made up of opposing forces yin and yang. Good health is maintained by achieving a balance between the internal body organs and five external elements: earth, fire, water, wood, and metal.


Despite the seemingly diverse theories, a common concept of health in ancient medical science (apart from the divine beliefs) is that a balance between various elements is necessary for good health. If you think about it carefully, that is not far from what we know today, and what the WHO has clearly stated as its mission for achieving global health: a synergistic balance between humans and the environment. It is very clear that the health of humans is dependent on the health of the planet. So in order to achieve good health, we need to learn to live harmoniously with nature. That's really akin to achieving a good balance in life.

Rx Symbol

Have you ever wondered why medicines are denoted with an ℞ or Rx symbol? There are actually many theories about its origin but the most common one is that the symbol for prescriptions originated from the "Eye of Horus", which was an ancient Egyptian symbol associated with healing powers. According to Egyptian mythology, Horus lost his eye in battle but his mom used her powers to restore his eye, hence it became a symbol of healing.  Eye of Horus In the 2 nd century, Greek physician Galen adapted this symbol to impress his patients. Galen’s influence on medicine was so strong that even the symbol was borrowed through the centuries and it eventually evolved into the modern symbol Rx (the eye of Horus kinda looks like an Rx). Other theories place its origin in Latin and Roman times. One theory is that Rx was used as an abbreviation of the Latin word recipere , meaning “to prepare,” which physicians wrote on medical prescriptions. Yet another theory points to the similarity of...

Concept of Qi

The Chinese (those who believe in Traditional Chinese Medicine) believe COVID-19 is caused by an imbalance of qi in the lungs. So what exactly is this qi? It has become a popular concept in the New Age movement, but it isn't very clear what it signifies, so I decided to dig a little deeper into it. Turns out, it is the fundamental basis of ancient Chinese medicine. Ancient Chinese medicine is based on the simple (in theory) principle that every system needs to be in harmony for health, well being and sustainability. When this harmony is broken, an imbalance is created in one direction and that leads to illness, disease, and many other sufferings. But it is more complicated than that- a system is not just a person, but everything that is interconnected and interdependent. That includes a family, community, environment… and the entire world. The harmony is created by two equal and opposite forces or elements: yin and yang. Qi (pronounced "chee") is the vital energy tha...

Origin of Neurology

As I consider majoring in neurobiology (the study of the biological mechanisms that control the nervous system) in college, I thought it would be interesting to delve into the origins of neuroscience. For hundreds of years from the ancient Egyptians to the Greeks, humans believed that the seat of intellect was the heart (which is why the ancient Egyptians went to great lengths to preserve the heart after death but discarded the brain!)    The birth of neurology began 2500 years ago with Hippocrates who pondered over the purpose and functioning of the brain, reasoning that the brain must be the organ controlling sensation simply because most sensory organs - eyes, ears, and tongue -- are located close to the brain. This was starkly different from other opinions of the time which held that the heart was the main organ that controlled everything in humans. The brain was simply thought to be a "radiator" for pumping the heart and keeping it cool.  Later, Hippocrates expanded ...
