Body Fluids are the third of Korean medicine’s three substances — all the normal fluids of the body. This foundational guide explains what Body Fluids are (and what they become when they turn abnormal), how they are made and moved by the spleen, lung, and kidney, what they do, and how they relate to Blood and Qi.
Blood in Korean Medicine: How It Is Made, What It Does, and Its Bond With Qi
Blood is the second of Korean medicine’s three substances. This foundational guide explains how Blood is made (food essence, with the spleen, kidney, heart, and lung each playing a part), what Blood does (nourishing and moistening body and mind), how it moves, and why Blood and Qi are an inseparable pair.
Qi in Korean Medicine: What It Is, Where It Comes From, and What It Does
Qi is the first of the three basic substances of Korean medicine. This foundational guide explains what Qi is (its formless and formed states), where it comes from (clear air and food essence), the main kinds of Qi, and the functions it performs — propulsion, warming, transformation, nourishment, containment, and defense.
The Liver and Edema: When Stagnant Qi Holds Water
The liver does not handle the body’s water directly — it governs the flow of Qi, and where Qi stalls, water stalls too. When stress knots the liver, a shifting, stress-linked edema follows, eased less by draining water than by the everyday liver care you already know.
The Kidney and Edema: The Root That Warms and Releases the Body’s Water
In Korean Traditional Medicine the kidney is the root of water metabolism — it warms the body’s water, transforms it, and governs its release. When the kidney is weak, as it is by constitution in the Soyangin types, edema tends to set in low, run cold, and linger.
The Spleen and Edema: When the Body Cannot Move Its Own Water
In Korean Traditional Medicine the spleen transports the body’s water. When the spleen is weak — common in the cold, weak-digestion Soeumin constitutions — edema turns heavy and sluggish, settles low and in the flesh, and comes with poor digestion.
The Lung and Edema: Why Some Swelling Begins Above the Kidney
Edema is usually blamed on the kidney, but the lung helps spread and descend the body’s fluids. When the lung is constitutionally weak — as in the Taeeumin types — swelling turns diffuse and whole-body, and stress through the liver makes it worse.
When a Plant-Based Diet Makes Your Metabolic Numbers Worse
Some people with metabolic disease follow a textbook plant-based diet faithfully and watch their liver, lipid, and glucose numbers worsen anyway. A pathologist explains why: for the liver-dominant constitutions Hepatonia and Cholecystonia, a plant-heavy diet works against the body’s structure — and the failing numbers signal a mismatched frame, not failed effort.
Seasonal and Local Food: Why They Work Even Without Knowing Your Constitution
You don’t need to know your constitution to eat well. Two old instincts do most of the work: local food, which generations adapted so every constitution could live on it, and seasonal food, which carries the qi the season demands rather than any one body’s. The eight-constitution diet is the finer layer added on top — not the foundation.
“All Your Tests Are Normal” but You Feel Terrible: A Pathologist on the Gap
Being told every test is normal while you feel terrible is usually not in your head. A pathologist explains the gap: Western medicine reads structure that has already broken, while Korean medicine reads function that goes wrong first. Functional disorders live in that gap — real suffering the structural tests were never built to see.
