If we saw the body as a flow of water — reading Korean medicine through circulation and pressure

When you look at our body as a single "flow of water," symptoms that never got better start to look different.

Blood and body fluids flow ceaselessly through the body, following differences in pressure. I see many chronic symptoms not as a case of some organ having broken down, but as a problem that arises when the regulation of this flow and pressure gets disrupted. In this article I want to explain what that perspective — seeing the body as a circulating fluid system — changes in the way I practice.

How does the body react when pressure gets disrupted

When a waterway narrows on one side, pressure builds up on the other. The body is the same.

• When the fine vessels in the periphery narrow, the heart has to push with higher pressure, and this shows up as blood pressure.
• When venous return slows, the legs feel heavy and swell.
• When you hold one posture for a long time, pressure stagnates in a particular area, producing pain and stiffness.

Seen this way, blood pressure, swelling, and pain may not be separate diseases but the same problem of flow revealed in several places.

Breathing and posture change the flow

The two biggest things that regulate the body's pressure moment to moment are breathing and posture. As you breathe, the diaphragm rises and falls, changing the pressure in the chest and abdomen, and this change helps circulate blood and lymph. When posture collapses, this pump action weakens and pressure concentrates in a particular area.

That is why, when I look at pain or a circulation problem, I don't look only at where it hurts but check breathing and body shape together as well. When the structure that generates the flow is shaky, several symptoms arise together beneath it.

The autonomic nervous system is the regulator of this flow

What decides whether to narrow or widen the vessels, whether to make the heart beat faster or slower, is the autonomic nervous system. In other words, the autonomic nervous system acts like a control valve that regulates the body's fluid flow in real time.

When this regulation tilts to one side — for example, when a state of tension continues for a long time — the peripheral vessels stay narrowed, so the hands and feet are cold, the heart keeps racing, and blood flow to the digestive tract decreases, making the stomach uncomfortable. This is why insomnia, palpitations, and cold hands and feet come together.

So treatment moves in the direction of "restoring the flow"

From this viewpoint, herbal medicine is a tool for adjusting the flow. I combine the ingredients in a direction that opens what has narrowed, drains what has pooled, and calms an over-tensed control valve. Acupuncture and Chuna release the structures where pressure has concentrated, reopening the path of flow. I first read what is blocked and what is overflowing in that person's body, and design the treatment accordingly.

Finally

This view cannot explain every disease. If organic damage is suspected, I recommend imaging or seeing a Western-medicine doctor first. But many of the cases where "the tests show nothing wrong, yet the body keeps struggling" are rooted precisely in this problem of flow and regulation. Looking into that flow together is the starting point of my practice.
