Chicken and ginseng are classified as beneficial for Renotonia and Vesicotonia. But a Water type whose heat has risen — headaches, sleepless nights — will not do well on a bowl of samgyetang, and I have written before about why. So are these foods simply closed off? Korean herbal pharmacy has an old answer, and it transfers directly to the kitchen. This article is about yeolinhanyong (열인한용 熱因寒用) and how to apply it to constitutional eating.
In Summary
- Yeolinhanyong (열인한용 熱因寒用) is a principle from Korean herbal pharmacy: a warming substance used in a cooled form.
- It means more than serving something cold. The core of it is changing the preparation and the pairing so the heating character is moderated.
- The standard illustration is liquorice. Raw, it runs relatively cool and is used to clear heat and resolve toxicity. Roasted with honey, its warming nature is amplified and it is used to restore energy in someone cold and depleted.
- Two reasons for doing this: to gentle the substance so it does not deliver a sharp shock, and to match it to its surroundings — the patient’s current state and the other ingredients.
- At the table: chogyeguksu — poached chicken in cold broth with vinegar and mustard — makes chicken usable for a Water type whose surface is hot.
- Samgyetang is the opposite manoeuvre: chicken plus ginseng plus glutinous rice, boiled hard, with the heating character maximised. Medicine for someone genuinely cold; the wrong thing for someone whose heat has risen.
- A constitutional diet is not a true-or-false quiz. Same ingredient, different preparation, according to the state you are in today.
What the Principle Actually Says
Korean herbal pharmacy has a set of principles for handling medicinal substances, and yeolinhanyong is one of them. The literal sense is a hot-natured substance administered in a cooled form.
Temperature is the shallow reading. What the principle really covers is altering the processing and the combination so that a strong warming character is softened before it is used. The substance stays what it is; how it is presented to the body changes.
Liquorice, Prepared Two Ways
The easiest demonstration is liquorice root, which is naturally warming and used to lift the qi of the digestive organs and replenish energy. What it does depends entirely on how it has been handled.
Raw liquorice — used as it comes, without roasting — runs comparatively cool. It is used chiefly to clear heat and resolve toxicity, and in a formula it regulates the other ingredients so that a combination of hot substances does not overheat. Combined with cooling substances, it helps them keep their character.
Roasted liquorice, coated with honey and taken over heat, has its natural warmth intensified. This is the form used to put energy back into someone whose interior is cold and whose strength is gone.
Same root. Opposite clinical uses.
Why Bother
Two reasons, and both transfer to food.
To gentle the substance. A strong property delivered undiluted gives the body an abrupt stimulus. Moderating it lets the same benefit arrive without the jolt.
To make it fit its surroundings. The surroundings are the patient’s present condition and the other ingredients in the formula. A substance that suits someone in principle may not suit the state they are in this month.
That second reason is the whole bridge to constitutional eating.
At the Table: Two Ways to Eat Chicken
Cold — chogyeguksu
If heat is the current problem, eat the chicken cold. Chogyeguksu is the summer dish: poached chicken in chilled broth, served with vinegar and mustard.
The chicken is warming by nature, but the cold temperature and the sourness of the vinegar together neutralise that heat. For a Water type with heat at the surface, this is a very suitable way to take a food that is otherwise beneficial to them.
Hot — samgyetang
The opposite case. If you are cold through, inside and out, with no strength at all, then the object is to make the dish as warming as it will go.
Samgyetang does exactly that: chicken (warming) with ginseng (warming) and warm-natured glutinous rice, boiled hard in an earthenware pot. It is a dish built to maximise the heating character of everything in it.
For someone genuinely cold this is medicine. For someone whose heat has risen it can do harm. Same food, opposite outcomes, and the deciding factor is not the constitution but the state.
What This Changes About Reading a Chart
A constitutional diet is not a true-or-false quiz. Holding the single sentence chicken is good for Water types and therefore insisting on samgyetang regardless of circumstance is a misreading of what the chart is for.
What is needed is the flexibility to prepare the same ingredient differently depending on whether you are running hot or cold right now. That is yeolinhanyong practised at the dinner table — gentling the character of a food so that it fits the body it is going into.
None of this is advice about taking any herbal medicine, and liquorice appears here to explain a principle rather than as something to take. Decisions about herbal treatment belong with the KTM physician treating you.
Summary
The chart tells you which ingredients suit your constitution. It does not tell you which form of them suits your condition, and that second question is often the one that decides whether a beneficial food helps you or makes things worse.
