The Theory of Four Humours
Imagine thinking that your entire health depended on balancing four mysterious fluids in your body! Ancient Greek physicians believed that four humours - blood, phlegm, yellow bile, and black bile - controlled everything about your health and personality.
This theory was brilliantly linked to nature through the theory of opposites. Each humour connected to different seasons and elements, creating what seemed like a logical system. When these humours became imbalanced, people believed you'd fall ill and need treatment to restore harmony.
The medical treatments weren't exactly pleasant though. Blood letting (literally draining blood from patients) and purging (forcing people to vomit or have severe diarrhoea) were common "cures" that often made patients worse rather than better.
Quick Fact: This theory lasted an incredible 1500 years - longer than Christianity has existed!
However, the four humours theory wasn't completely useless. It encouraged people to live balanced lifestyles, made doctors observe their patients more carefully, and got physicians thinking systematically about health rather than just blaming gods or evil spirits.

Hippocrates and Galen: Medical Pioneers
Meet Hippocrates, the famous Greek doctor who's still influencing medicine today! He developed the four humours theory and created something even more lasting - the Hippocratic Oath, where doctors promise not to harm patients and keep medical information confidential.
Hippocrates revolutionised medicine by making doctors actually think about patient care systematically. Instead of just hoping for divine intervention, physicians started observing symptoms and considering treatments more carefully.
Then came Galen, whose work was enthusiastically supported by Christians because his ideas about the human body seemed to align with religious beliefs about divine design. Unfortunately, Galen made a massive mistake that held back medical progress for centuries.
Did You Know?: Galen's biggest error was assuming that animal anatomy was identical to human anatomy because he only dissected animals, not humans.
This assumption meant Galen got loads of things wrong about how the human body actually works. Since the Christian church supported his ideas so strongly, questioning Galen became almost like questioning religious doctrine - which seriously hindered medical development for hundreds of years.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
