The most important medieval theory came from ancient Greece. Hippocrates (c.460-370 BC) developed it; Galen (c.130-210 AD) expanded it. The idea: the body contains four "humours" (liquids), and illness happens when they're out of balance.
| Humour | Element | Qualities | Season | If Too Much... |
|---|---|---|---|---|
| Blood | Air | Hot & Wet | Spring | Bleeding to reduce it |
| Yellow Bile | Fire | Hot & Dry | Summer | Purging (laxatives) |
| Phlegm | Water | Cold & Wet | Winter | Advised to keep warm |
| Black Bile | Earth | Cold & Dry | Autumn | Purging or bleeding |
