What is cheonsangap?

Cheonsangap is the dried scale of the pangolin. A pangolin is a small, scale-covered animal that eats ants. Its Latin name is Manis pentadactyla, and the scales are also sold as pangolin scales.

In old Korean and Chinese medicine, healers used the scales to "unblock" stuck blood. They gave them to help breast milk flow, to bring on late periods, and to drain pus from boils.

Here is the short answer on evidence. No human trial has shown that pangolin scale helps any health problem. Long use in a tradition is not proof that a remedy works.

There is a second point, and it is just as plain. All pangolins are protected animals. Buying, selling or holding the scales is against the law in Korea and in nearly every other country.

How does cheonsangap work?

The honest answer is that no one has shown it does anything in the body. Pangolin scale is made of keratin. That is the same tough protein as your fingernails and hair.

Old texts explain it in their own way. They say the scale "pierces" and moves blocked blood and opens the body's channels. That is a traditional idea, not a tested one.

Lab work on ground scale finds little of note. Cow hoof and human nail have much the same make-up. So there is no clear way it could act like a drug.

What forms does cheonsangap come in?

You will not find a legal, tested form of this. What appears on the black market takes a few shapes.

Whole dried scales are the raw form. Scales fried in hot sand until they puff are the prepared form used in old recipes. Ground powder is sold loose or packed into capsules.

Some imported pill and tea mixes list it as one part of a multi-herb blend. These blends are also illegal, and the label may not match what is inside.

Where it comes from:

Chinese medical texts named pangolin scale by about 500 CE. Korean medicine took it up from those texts.

It appears in the Donguibogam, the great Korean medical book of 1613, and stayed in use for centuries for milk flow, sores and stuck blood.

Its standing has since changed. China dropped pangolin scale from its official medicine list in 2020, and world trade rules ban the trade outright.

What does cheonsangap help with?

• Low breast milk supply: This is the best known old use. Korean and Chinese healers boiled the scale to help milk let down. No human trial has tested it for this. Safer, tested steps exist, such as feeding often and getting help with latch from a nurse or midwife.
• Boils and abscesses (pockets of pus under the skin): Old texts used it to "draw out" pus and help sores burst and drain. No trial supports this. A boil that grows, throbs or comes with fever needs a doctor, who may drain it or give an antibiotic.
• Late or missing periods: Tradition treats it as a strong "blood-moving" agent for stuck or absent periods. There is no trial evidence. The same property is why old texts told pregnant women never to take it.
• Joint and limb pain: It was added to mixes for stiff, painful joints and numb limbs. No human study has looked at this use. Nothing in its make-up suggests a pain-killing effect.
• Lumps and swellings: Old writers used it for hard lumps and swollen glands. This is a traditional idea only. Any new lump should be checked by a doctor rather than treated at home.

Which foods are rich in cheonsangap?

There is no food source and no food to pair it with.

What are the side effects of cheonsangap?

• Upset stomach, nausea or loose stools
• Rash, itching or swelling from an allergy
• Stomach or gut infection from germs in raw animal parts
• Poisoning from lead or other metals in fake or dirty product
• Miscarriage risk in pregnancy, warned about in the old texts
• Harm from putting off care that works

Good to know:

We do not know how often these happen. No one has tested pangolin scale in a proper trial, so there is no safety record to quote.

The biggest risks may not come from the scale itself. They come from germs in raw animal parts, from metals and junk mixed into fake product, and from waiting too long to get real care.

Stop taking it and get help if you feel unwell.

How much cheonsangap should you take?

• Recommended daily: There is no amount we can suggest. No trial has set a safe or useful dose, and legal supply does not exist. For the record only, old Korean and Chinese texts used about 3 to 10 g of prepared scale boiled in water, or 1 to 1.5 g of powder a day. Those numbers come from tradition, not from testing.
• Best time of day: No time of day has been studied. Old texts gave the boiled drink in one or two servings across the day.
• With or without food: Not studied. Old practice gave the warm drink between meals.
• Time to effect: Unknown. No trial has measured any effect, so no honest time frame can be given.
• How long to take it: No length of use has been tested. Old recipes were short, running a few days to a few weeks. If you are treating a skin infection or a milk supply problem yourself, give it 24 to 48 hours at most before you ask a doctor, nurse or midwife for help.
