Is a Tonic a Medicine That Pours in Good Things?

"I have no energy, so I would like to have a tonic made."

When autumn comes, more people arrive with words like these. And most add this: "Please put good ingredients in."

I always hesitate for a moment at these words. Not out of indifference. It is because the phrase "putting good things in" makes people misunderstand what a tonic is.

Putting in and being used are different

Let me ask a simple question.

Is the lack of energy because the materials are missing, or because you cannot use the materials?

Many people have no energy even though they eat well. Some even gain weight while always feeling tired. For such a person, would adding more good materials be the answer?

Think of a generator. A generator that has stopped because it ran out of fuel needs fuel added. But if the fuel tank is full and the generator will not turn, pouring in more fuel is of no use. It only overflows.

The body is the same. If the work of producing energy has broken down, putting in materials does not become energy.

So I separate three cases

When I see someone who comes saying they have no energy, I first look for where the blockage is.

First, the case where the materials do not come in.
They eat but cannot absorb. When the gut has been over-excited for a long time, it gives up the work of taking things in. For such a person, no matter how much good you put in, it passes straight through. First, the gut must settle.

Second, the case where the body cannot produce.
The materials came in, but they are not converted into energy. The generating process inside the cell has broken down. What this person needs is not materials but to get the generator turning again.

Third, the case where the body cannot clear away.
This is the site that is often missed. Once what has been produced is used, waste remains. If that waste pools around the cells, the cells cannot take in anything new. For such a person, it is not putting in but emptying out that comes first.

A tonic is not a medicine that fills; it is a medicine that finds where the blockage is and opens it.

The filling medicine and the emptying medicine

The old medical texts held this distinction too. I read it this way.

	What it does	When it is used
The filling side	Pushes the cells to work again	When the generator has lost its power
The emptying side	Tidies the area around the cells	When waste has pooled

What happens if you use the two the wrong way round?

If you give a filling medicine to someone who is congested, they grow heavier and more stifled. They swell, digestion falters, and they sink further.

If you give an emptying medicine to someone who is depleted, their energy drains further. The body cannot bear it.

That is why a tonic is not a good medicine at just any time. You must read which side this person's body is on right now.

Why I do not use a tonic when you have a cold

A frequent question: "They say a tonic is not good for a cold?"

While the body is fighting an infection, the immune system must stay switched on. If you intervene at this point in a direction that makes the body comfortable, the fight can drag out.

This is not because a tonic is bad. It is a matter of timing. What you need when there is a fire is an extinguisher, not a meal. Once the fire is out, then you can help with recovery.

So when is a good time?

When the body is not fighting something right now.
While there is acute inflammation, infection, or fever, I hold off.

After confirming the order in which things broke down.
You must know whether the problem is absorption, metabolism, or circulation to decide where to begin.

After checking the medicines you take.
As I said in an earlier article, when licorice meets a diuretic it can be dangerous. A tonic is no exception.

A season is a good occasion to begin. But whether the body is ready comes before the season.

My answer to "Please put good ingredients in"

Is a tonic good because you put in many expensive herbs?

I do not think so. A good medicine is one whose contents get used.

However precious the ingredient, it is of no use if it is not absorbed. If the cells are not ready to take it in, it is only a burden. It must enter in a size the body can manage for the body to use it.

That is why I sometimes give a prescription that uses little. Some are disappointed. It seems as though something grand ought to go in, and it does not.

But if it is a medicine that wakes the body rather than one that works in its place, what is needed is a signal large enough to be noticed, not an amount large enough to overwhelm.

In these cases it is not a tonic but a test

There are cases where the lack of energy must not be seen only as "run-down stamina." If weight is clearly dropping, if there are night sweats, or if fatigue that does not recover even after sleep has continued for months — anemia, the thyroid, and diabetes sometimes arrive wearing these faces. When I see signals like these, I recommend a test before making a medicine. That is the order.

Recovery rests on absorption, on metabolism, and on the environment around the cells together.

However, exactly which herb does which of these has not yet been sufficiently clarified in humans. There is always a distance between what is observed in the laboratory and the human body.

The distinction I described between "the filling side and the emptying side" is also a re-reading of long clinical observation in modern language, not a textbook classification.

To the words "Please make me a tonic," I ask back this.

"Let me first look into why it is that you have no energy."

What to put in is the next question. Putting good things in without knowing where the blockage is, is no different from pouring water into a blocked pipe.
