Sikbangpung, also called gaetbangpung, is a leafy coastal plant. Its Latin name is Peucedanum japonicum. In English it is sold as coastal hog fennel greens.
In Korea it is used in two ways. The young leaves are eaten as a spring green. The root and leaf are also brewed as a folk tea for aches, chills and stiff joints.
Here is the short verdict. The plant has a long food and folk record in Korea. We found no human trials for it, so old use is not proof that it treats any illness.
No one has shown how it works in people. Lab work points to a few plant chemicals in the root and leaf.
In test tubes and in mice, these chemicals calm swelling. A few also relax blood vessels. Cell and mouse work is a weak guide to what happens in a person.
A cup of tea or a plate of greens gives a small dose. That dose is likely far below what lab tests used. So treat any claim of effect as unproven.
Most people meet it as food. Fresh leaves and shoots are blanched and dressed as namul, a seasoned side dish. In Japan the leaves are often fried in batter.
As a herb it is sold as dried root or dried leaf for tea. You may also see powder, capsules or a liquid extract.
One label warning matters. Dried gaetbangpung root is sometimes sold as bangpung. True bangpung is a different plant, Saposhnikovia divaricata.
Gaetbangpung grows on sandy shores in southern Korea and on Jeju Island. The name means beach bangpung. Village cooks picked the young leaves each spring.
The root was used at home as a cheaper stand-in for true bangpung root. Korean and Japanese texts treat the two as separate plants.
In Japan the same plant is grown in Okinawa and eaten most days as a green.
See a doctor if joint pain, a cough or a headache lasts more than two weeks, or gets worse. Get help the same day if you bruise or bleed more easily than normal, if your skin blisters after being in the sun, or if a rash spreads. Go to an emergency department if your lips, tongue or throat swell, or if you struggle to breathe. Always tell your doctor or pharmacist that you are taking this, especially before any surgery.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Sikbangpung (gaetbangpung) 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.
