Guhyangchung is a dried insect used as a single medicine in Korean herbal practice. Its Latin name is Aspongopus chinensis. In plain words, it is a stink bug, and it is roasted before use.
Old Korean and Chinese books use it for stomach pain, bloating and a tight feeling in the chest. They also use it for low back pain and as a warming tonic for tiredness. It is nearly always mixed into a larger herb formula, not taken on its own.
Here is the honest verdict. No human trial has tested it for any of these uses. Long use in tradition is not proof that a remedy works, and that gap applies to every claim on this page.
No one has shown how it works in a person. What follows is theory.
Korean medicine says it warms the middle of the body. It is also said to move stuck qi (the flow of energy in old East Asian theory). Those are traditional ideas, not lab findings.
Lab work gives a few hints. The insect holds fats, protein and strong-smelling oils. In dishes and in animals, some of these slow germ growth or dull pain.
Those tests cannot tell you what happens in a human gut. Treat the story about how it works as a guess, not a fact.
Whole dried insects are the main form. A seller roasts them first, which softens the smell.
Ground powder is the next most common form. The powder is pressed into pills, packed into capsules, or rolled with honey.
A Korean medicine doctor may add it to a pot of herbs that you boil and drink. Some soak it in rice wine instead.
You will rarely see it sold alone outside Korea and China. Check that any pack names the insect and says where it was collected.
It has been used in East Asia for several hundred years. Chinese drug books call it jiuxiangchong, and Korean practice took it from those texts.
The Bencao Gangmu, a Chinese drug book from the 1500s, lists it for stomach pain and for weak yang. Korean doctors used it in the same way, in small doses inside bigger formulas.
It has always been a minor remedy. It was never a daily household item like ginseng or ginger.
Some reactions to Guhyangchung need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Call emergency services at once if your lips, tongue or throat swell, if you wheeze or struggle to breathe, if you feel faint, or if a rash spreads fast over your body. These are signs of a severe allergic reaction and they need help within minutes.
Stop it and ring your doctor the same day if you get hives, itching, repeated vomiting, or a fever after taking it.
See a doctor before you try it at all if your stomach pain is severe, wakes you at night, or comes with black stools, blood, or weight loss you did not plan. Those signs need tests, not a herb. The same goes for new erection problems or back pain that follows an injury.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Guhyangchung is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
