The Chylos Edition
Stories of balance, every month.
Investigations, true stories and honest answers about the oldest medicine of balance, and how it can be lived today.
Edition 00 · The Four · Free at launch
We don’t brief. We investigate and narrate.
Anyone can tell you what the four temperaments are. We go and find out what they meant, and what they still mean.
Reported
Interviews with practitioners, historians and scientists. Real people, real places, named sources.
Told as stories
Patients, physicians, foods and seasons. Every piece has a story at its heart.
Honest answers
Where old ideas meet modern evidence, we say what holds up, and what does not.
Issue highlights

Long before Athens, the world was made of four elements. The Greeks turned them into a body. Arabic physicians turned the body into a medicine. We follow the trail to the one word at its centre.

For centuries, physicians of the old medicine linked one small spice to the heart. We follow the thread, from the spice routes to the modern lab.
