About Chylos

We investigate one of the oldest systems of medicine, and bring it to life through film, books and tools you can live by.

Chylosχυλός · juice

In ancient medicine, food was digested into chylos. The body turned it into four humours.

  • Blood
  • Yellow bile
  • Black bile
  • Phlegm

Their balance was health. Their imbalance was illness. Every meal, habit and season moved that balance. That is why we chose the name: it begins with what we eat.

Why we exist

Modern medicine defeated many enemies from outside. Today, the illnesses that take most lives begin inside us, and most of them have no verified cure.

Long before laboratories, physicians looked at the whole person: temperament, food, habit and season.

We want to know what they saw, and what it can still teach us.

How we work

  • Investigate first

    We go to the sources: the old texts, historians and modern science. We say what is known, and what is not.

  • Plain words

    No jargon. Anyone, anywhere, should be able to understand this tradition and use it.

  • Safety always

    Tradition does not replace your doctor. Our tools help you understand yourself, safely.
