Prof. Seungho Baek's Medical Insight

Pancreotonia and Gastrotonia tolerate caffeine well. But the thing that most often breaks their concentration is not fatigue — it is hurry, and caffeine makes hurry worse.

For Pulmotonia and Colonotonia, caffeine borrows alertness against tomorrow rather than generating it. What the Gold types actually run on is different — and so is what calms them.

Most constitutional advice about coffee is a warning. For the Wood types it is the opposite — and the reason is autonomic rather than a matter of taste.

Aloe, green juice, honey, cold water, more vegetables — every one of these is standard constipation advice, and every one of them is wrong for some constitutions. What resolves a blocked bowel in one person entrenches it in another.

Urine varies little from person to person. Stool varies enormously — and in Eight Constitution Medicine that variation is not random. Some types are healthy going three times a day; others are healthy going once every five.

They share the same ancient texts. But one was absorbed into the mainstream health system and the other had to survive outside it — and that structural difference produced two quite different medicines, including the constitutional theory this site is built on.

Four types, eight types — it looks like subdivision. But the two systems start from different questions, diagnose differently and treat differently, and mixing their methods produces clinical confusion rather than a richer picture.

Classical medicine projected the cosmos onto the body. Lee Je-ma reversed the direction — analyse the human being first, then assign the organs. The reassignment that follows looks radical, and it is best understood as a lens rather than a correction.

The frail, poorly digesting Soeumin of popular description is closer to Vesicotonia. Renotonia is the same category with a different texture — brighter, more sociable, and prone to a constipation that never bothers them.
