The Tests Are Normal, But You Still Feel Unwell — Explaining Herbal Medicine Through Modern Pharmacology

There are people whose test results come back normal, yet whose bodies still feel unwell.

Insomnia, palpitations, indigestion, chronic fatigue. Often they get tested at several hospitals only to be told "nothing is wrong" and sent away. In those moments, I tell my patients this: it is a fortunate thing that the tests show no abnormality, but that does not mean "your body is working normally."

I am a Korean medicine doctor who prescribes herbal medicine. But I try not to explain herbal medicine only in the old language of "your qi is deficient, so we tonify it." What is actually happening in the body — how the blood flows, where pressure accumulates, how the nerves respond — I explain it through those principles, and I compose herbal formulas that fit them. This article is a direct transcription of the explanation I give my patients in the consultation room.

Why Do the Tests Come Back Normal While You Still Feel Unwell

Hospital tests mostly look at the question of "is there inflammation in the tissue, has organic damage occurred." Whether inflammatory markers have risen, whether tissue is eroded or broken down, whether there is a tumor. These things show up well on tests.

Yet many symptoms appear before organic damage sets in, because the body's internal environment and function are the first to go wrong. It is not that the heart is diseased but that the autonomic nervous system regulating the heartbeat has become oversensitive; not that the stomach is eroded but that the nerves directing digestion are not doing their job. These problems of function and environment shift moment to moment and have not yet damaged the tissue, so they are hard to capture in an image taken at a single point in time.

That is why "nothing is wrong" and "you are fine" are two different statements. I begin my care by looking for this disturbance in regulatory function.

How Do I Understand and Prescribe Herbal Medicine

Each herbal ingredient is in fact a bundle of many pharmacological compounds. For a long time I have studied what these compounds actually do in the body. Here are a few examples.

• The perspective of blood flow and pressure. Some herbs relax narrowed blood vessels to aid circulation; others help drain fluid that has pooled in one place. I compose a prescription by asking, "in this person's circulation, what is blocked and what is overflowing."
• The perspective of absorption. A large portion of herbal compounds are not absorbed directly in the stomach but are first transformed by the microbes in the large intestine into a form the body can use, and then absorbed. So even the same medicine works differently depending on the state of the gut. That is why I examine digestion and the gut together.
• The perspective of the nerves and their responses. Some herbs calm nerves that are overly tense; others stabilize abrupt reactions. This matters especially when approaching autonomic symptoms.

Seen this way, even the same "insomnia" has different causes from person to person, so the prescription differs. Rather than giving everyone one predetermined formula, I compose it to fit that person's condition — that is what herbal medicine care means to me.

Why Do I Try to Explain This Far

One reason is that recovery begins when a patient understands their own body. Once it makes sense why a symptom arose and why this medicine is being used, they can carry on the course of treatment and manage their daily life on their own.

The other reason is my own personal experience. I too am someone who has directly experienced the symptoms that come when the autonomic nervous system wavers. Because I know the frustration of that time — when the tests said there was no real problem yet the body kept feeling uncomfortable — I do not take my patients' symptoms lightly.

Who Might This Help

• Those who have been to several hospitals but heard only "nothing is wrong" while the symptoms remain
• Those whose autonomic-related symptoms overlap, such as insomnia, palpitations, dizziness, and cold hands and feet
• Those whose blood pressure, blood sugar, and weight are not being managed together, requiring a look at overall metabolism
• Those whose long-standing pain improves only briefly during treatment and then recurs
• Those who want to be treated after hearing a full explanation of why they hurt and why this medicine

But let me be clear. I do not say that herbal medicine solves everything. When needed, I first recommend imaging tests or Western medical care, and I honestly point out where Korean medicine treatment can actually help in your current condition. Neither vague expectation nor premature resignation — finding a grounded direction together is where my care begins.
