What is Sseumbagwi?

Sseumbagwi is a small wild green that grows all over Korea. Its Latin name is Ixeris dentata. In English it is called toothed ixeris.

Cooks pick the young leaves and the root in spring. The taste is very bitter. Most people eat it as namul, a dressed side dish, or put it in kimchi.

In old Korean home use, the bitter taste was said to wake up the appetite and settle an upset stomach. The proof for this is thin. Nearly all of it comes from lab dishes and animals, not people.

Long use as a food does not show that a plant treats any illness.

How does Sseumbagwi work?

No one has shown how Sseumbagwi works in people.

The plant is full of bitter compounds. Bitter foods make the mouth water and may get the gut moving. That is a general idea about bitter greens, not a proven fact about this one.

In lab dishes and in rats, extracts have calmed swelling and lowered blood sugar a little. Some rat work also hints at a guard effect on the stomach lining and the liver. Results in animals often do not carry over to people.

What forms does Sseumbagwi come in?

Fresh leaves are by far the most common form. Cooks boil them fast, squeeze out the water, then dress them with soybean paste, garlic and sesame oil.

You may also meet dried leaf or root for tea, whole plant in kimchi, fresh juice, dried powder, and extract capsules.

The food forms are the best known, which here means barely known at all. Strong extracts are newer and less well understood.

Where it comes from:

Koreans have picked Sseumbagwi as a spring green for hundreds of years. It shows up in Joseon-era food records and in famine records, where wild greens kept people fed.

Korean folk healers used the bitter leaf and root for poor appetite, upset stomach, fever and coughs.

It belongs to hyangyak, the tradition of local Korean herbs, rather than to the classic Chinese herb books.

What does Sseumbagwi help with?

• Poor appetite: This is the main folk use. Bitter foods make the mouth water and can make a meal more welcome. No trial in people has tested Sseumbagwi for appetite.
• Upset stomach and bloating: Korean home use gives the bitter leaf for a heavy, full feeling after eating. Rat work hints at a guard effect on the stomach lining. There is no human proof.
• Spring tiredness and heavy limbs: Wild spring greens were eaten to shake off winter dullness. Part of the benefit was simply fresh food after a lean season. No study has tested this idea.
• Mild fever and sore throat (folk use): Folk healers used the root as a cooling herb for heat and throat pain. This is tradition only. Do not rely on it for a fever that is high or lasting.
• Sluggish bowels: A big serving of any leafy green adds fibre and water, which helps stools pass. That effect comes from the fibre, not from anything special to this plant.

Which foods are rich in Sseumbagwi?

1. Sseumbagwi namul: blanched leaves dressed with soybean paste, garlic and sesame oil
2. Sseumbagwi kimchi: the whole plant, root and all, salted and fermented
3. Spring wild-green platters: served with other picked greens such as dallae and naengi
4. Sseumbagwi tea: dried leaf or root steeped in hot water
5. Fresh green juice: pressed leaves, sometimes mixed with apple or pear to cut the bitterness

Practical Tips:

The plant is a food first. Blanching and squeezing it removes some of the bitterness.

What are the side effects of Sseumbagwi?

• Very bitter taste, which some people find sickening
• Nausea or loose stools after a large helping
• Burning or itching in the mouth and throat
• Skin rash from the milky sap on your hands
• Rash, swelling or wheeze in people allergic to daisy-family plants
• Blood sugar dipping lower than usual, if you take diabetes medicine

Good to know:

As a cooked food, Sseumbagwi is well tolerated. Koreans have eaten it for centuries with no pattern of harm on record.

Most trouble comes from the taste or from eating a lot at once. Serious reactions are rare, and nearly all of them are allergy.

Strong extracts and capsules have not been checked for safety in people, so treat them with more care than food.

How much Sseumbagwi should you take?

• Recommended daily: No safe or useful dose has been set for Sseumbagwi, because no one has tested doses in people. As food, a normal side dish is about 50 to 100 g of fresh cooked leaves. Folk tea uses roughly 5 to 10 g of dried plant steeped in hot water. For capsules or extracts, follow the label and do not go over it.
• Best time of day: Take it with a meal, or ten to twenty minutes before one. That is when bitters are said to be most useful.
• With or without food: With food, or just before you eat. A strong bitter extract on an empty stomach can sting and may turn your stomach.
• Time to effect: If bitters help your appetite at all, you would notice within a day or two. Nothing about this plant is known to build up slowly over weeks.
• How long to take it: Eat it as a food in season, the way you would eat any green. There is no known limit for food amounts. If you take a tea or capsule for a stomach complaint, give it two to four weeks. Then stop and ask yourself if anything really changed. Do not keep paying for a supplement that is doing nothing for you.
