What is goehwa? Goehwa is the dried flower bud of the pagoda tree. It is used as a single herb in Korean medicine, not as part of a set formula. Its Latin name is Styphnolobium japonicum, and it is also sold as pagoda tree flower bud. Healers have long given it to slow bleeding. Old uses include blood in the stool, piles (swollen veins in the back passage) and nosebleeds. It was also used for red, hot skin and for dizziness. Human trial proof for the herb itself is thin. Long use in a tradition is not proof that a herb works. Please read the bleeding warnings below before you try it. How does goehwa work? Goehwa is rich in rutin, a plant pigment. Lab work suggests rutin may make small blood vessels less leaky. That fits the old use for bleeding. Rutin and quercetin also mop up free radicals (unstable molecules that can harm cells) in lab dishes. Whether this helps a person who drinks the tea is not known. No one has traced the full path from cup to blood vessel. What forms does goehwa come in? Loose dried buds are the usual form. You steep them in hot water as a tea. Roasted buds are also sold. In Korean and Chinese practice, roasting was the old step used when the goal was to slow bleeding. Powders, capsules and ready-made granules are easy to find. Rutin tablets are a different thing. They hold one purified part of the plant, not the whole herb. Where it comes from: Goehwa has a long record across East Asia. Korean texts such as the Dongui Bogam list it for bleeding. Chinese and Japanese texts use it in much the same way. The tree is often planted at temples and along roads. Buds are picked in early summer, just before they open. Roasting them, called charring, is an old step shared by Korean and Chinese herbalists.

Helps

What does goehwa help with? Bleeding from piles (swollen veins in the back passage): This is the best known old use, both as a tea and as a wash. We found no human trial of goehwa for it. Bleeding from the back passage needs a check-up first, since it can come from something serious. Blood in the stool: Korean texts list goehwa for this, often in roasted form. There is no trial proof. Blood in the stool always needs a doctor, not a home herb. Nosebleeds: Old texts group nosebleeds with other heat-driven bleeding and use goehwa for them. Human evidence is absent. Nosebleeds that keep coming back should be looked at by a doctor. Heavy monthly bleeding: Some old books list it for heavy or long periods. No trial has tested this. Heavy bleeding has many causes, and some of them need treatment. Easy bruising and fragile small blood vessels: Lab work on rutin, one part of the bud, points to firmer capillaries (the smallest blood vessels). That is a lab finding, not a proven result in people who take the herb. High blood pressure (old use only): Goehwa was given for dizziness and headache linked to what old texts called rising heat. This is not the same as measured blood pressure. Do not use it in place of blood pressure medicine.

If this is an emergency

Some reactions to goehwa need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.

Who should avoid goehwa?

  • Do not use if you take warfarin, heparin, rivaroxaban, apixaban or any other blood thinner, unless your doctor has agreed and is checking you.
  • Do not use if you take antiplatelet drugs (medicines that stop blood cells from sticking together) such as aspirin or clopidogrel.
  • Do not use if you have a bleeding disorder such as haemophilia (a condition where the blood does not clot properly) or a low platelet count.
  • Do not use in the two weeks before any planned surgery, including dental surgery.
  • Do not use if you are pregnant or trying to get pregnant.
  • Do not use if you are breastfeeding.
  • Do not use if you are allergic to pagoda tree pollen or to plants in the pea family.
  • Do not give it to a child unless a doctor is guiding the care.
  • Never rely on goehwa to stop bleeding that is heavy, will not stop, or keeps coming back. Get medical help instead.

When should you see a doctor?

See a doctor before you start if you have any bleeding you cannot explain. Blood in the stool, black tar-like stools, bleeding between periods or after the menopause all need a proper check, because they can come from something serious.

Stop the herb and get help the same day if you bruise easily, bleed from the gums or nose, or feel dizzy and weak. Call emergency services for heavy bleeding that will not stop, for vomit that looks like coffee grounds, or for swelling of the face, lips or throat.
