What is Haema?

Haema is a dried seahorse. Its Latin name is Hippocampus japonicus. In Korean medicine it is used as a warming tonic, mostly for low sex drive, weak knees and long-term wheezing.

It is sold whole, in slices, or ground to powder. It is also soaked in wine or added to soups. It is one single drug, not a herb blend.

Old use is not proof that a remedy works. No human trials of Haema have been found. Read the uses below as tradition, not as fact.

How does Haema work?

No one has shown how Haema works in the body. That is the honest answer.

Korean texts say it warms the kidney and lifts yang, the body's inner fire. In plain words, it was thought to add warmth, drive and strength.

A few lab and animal studies look at seahorse extract. They hint at effects on swelling and on hormones, the body's chemical messengers. None of that shows a result in people.

What forms does Haema come in?

Haema comes as a whole dried seahorse or as thin slices. It is also ground into a fine powder.

Cooks and healers simmer it in soup or soak it in rice wine. Some mixed pills and capsules list it with other herbs.

Quality and purity vary widely. Seahorses are protected in many countries, so trade is limited by law. Buy only stock that is legal and lab tested.

Where it comes from:

Seahorse has been used in East Asia for hundreds of years. It shows up in Chinese drug books from the Ming era, then in Korean practice.

Korean doctors gave it as a warming tonic to men, and to speed up slow births. They also used it on lumps and slow-healing sores.

It is a named single drug in Korean medicine, but a small one. It was never an everyday staple like ginseng.

What does Haema help with?

• Low sex drive and weak erections: This is the best known use of Haema in Korea. Texts group it with other warming kidney tonics for men. No human trial has tested it for this. If erections change suddenly, see a doctor; it can be an early sign of heart or blood sugar trouble.
• Tiredness with a weak, cold low back and knees: Old practice used Haema for people who felt cold, drained and weak in the legs. It was often cooked with other tonic herbs. There is no trial evidence for this use. Long-lasting tiredness needs a check-up, not a tonic.
• Long-term wheezing and shortness of breath: Korean and Chinese texts list seahorse for long-term wheezing with a cold, weak pattern. No trial has tested it against a dummy pill. Never swap it for an inhaler or other asthma medicine.
• Lumps, swellings and slow-healing sores: Tradition says Haema moves blood and breaks up lumps. Some lab work looks at swelling in cells and animals, which is a long way from proof. Any new lump should be checked by a doctor first.
• Slow or hard labour: Old Korean and Chinese practice used seahorse to bring on or speed up labour. That is exactly why it is not safe in pregnancy today. Do not use it for this reason.

Which foods are rich in Haema?

1. Seahorse tonic soup: dried seahorse simmered with other herbs, a folk dish
2. Seahorse wine: dried seahorse steeped in rice wine, a folk preparation

Practical Tips:

Haema is not a nutrient found in everyday food.

What are the side effects of Haema?

• Allergic reaction in people who react to fish or shellfish
• Rash or itching
• Upset stomach, nausea or loose stools
• Feeling hot, flushed or restless
• Trouble sleeping if taken late in the day
• Heavy metal build-up with long or heavy use of untested stock

Good to know:

Side effects are not well counted, because no trial has tracked them. Most reports are mild: stomach upset, rash or feeling too warm.

The two real worries are allergy and purity. A seafood allergy can turn serious fast. Untested wild stock may carry mercury or other heavy metals.

How much Haema should you take?

• Recommended daily: There is no dose set by modern research. Classical texts suggest roughly 3 to 9 grams of the dried animal, cooked in water, or about 1 to 1.5 grams as powder. Take these as history, not as advice. If you use it at all, work with a trained Korean medicine practitioner. Do not raise the amount on your own.
• Best time of day: Tradition favours the morning or early evening. Some people feel warm or restless if they take it late at night.
• With or without food: It is usually taken with food or cooked into soup. Food may lower the chance of stomach upset.
• Time to effect: No trial has measured this. Old texts speak of weeks, not days.
• How long to take it: Old practice used short courses, often two to four weeks. Stop and rethink if nothing has changed after a month. Long daily use is not wise. Sea animals can carry heavy metals that build up over time.
