Pogongyeong is the dried whole dandelion plant, roots and all. In Korean medicine it comes from Taraxacum platycarpum or Taraxacum mongolicum. English speakers call it dandelion herb.
It is a single herb, not a blend. Healers have long used it as a cooling, bitter herb for hot, swollen skin sores, sore breasts during breastfeeding, and slow digestion. Today people also take it as a mild water pill.
Here is the short verdict. Its place in tradition is strong and old, but good human trials are lacking. Long use is not proof that a herb works, and we say that once here rather than in every section below.
The honest answer is that no one has shown how it works in people. Nearly all the research sits in lab dishes and in animals.
Dandelion is bitter. Bitter plants are thought to make the gut release more bile, the fluid that helps you break down fat. That may be why it has long been used for a heavy, bloated stomach.
The plant is also high in potassium (a mineral your body needs), and animal work suggests it can make the body pass more urine. Lab tests show the plant can slow some bacteria and calm swelling in cells. None of that tells us what happens in a person who drinks the tea.
The classic Korean form is the dried whole herb, boiled into a decoction (a strong tea made by simmering herbs in water).
You may also find it as a powder, as granules that dissolve in hot water, as capsules, as a tincture (a liquid herb extract in alcohol), and as part of mixed herb formulas.
Fresh dandelion leaves are eaten as a vegetable and in salads, and roasted root is sold as a coffee substitute.
Korean doctors have used Pogongyeong for many hundreds of years. It appears in old East Asian herb books under the Chinese name pu gong ying.
Healers reached for it when skin sores were hot and swollen, and when a nursing mother had a hard, painful breast.
Dandelion is also an old folk remedy in Japan and across Europe, where it was used for the liver, the gut and fluid build-up. That wide record is why it sits high on the traditional axis.
See a doctor if a skin sore spreads, weeps pus or comes with fever. See a doctor within a day if a breast becomes hot, hard and painful, or if you have fever while breastfeeding, because this can be mastitis (an infection of the breast) that needs antibiotics.
Get care if swelling in your legs or belly is new or getting worse, or if you have burning urine with fever or back pain.
Get emergency help at once if your lips, tongue or throat swell, if a rash spreads fast, or if you cannot breathe properly.
Also speak to your pharmacist before starting it if you take a water pill, a blood thinner, a diabetes medicine or a blood pressure medicine.

The published evidence for Pogongyeong 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.
