Ye Ju Hua is the dried flower of wild chrysanthemum. The plant is called Chrysanthemum indicum. It is one herb on its own, not a mixed formula.
Chinese medicine uses it to cool what it calls heat and toxin. In plain words, people take it for boils, skin sores, a sore throat, and red itchy eyes. It also turns up in cold and flu tea blends.
Here is the short verdict. It has a long record of use in China, but human trial data is thin. A long record of use is not proof that a herb works.
No one has shown how Ye Ju Hua works in people. Lab work is the main source of ideas about it.
In a dish, its plant compounds can slow the growth of some bacteria. Lab and animal tests also point to a mild anti-swelling effect. These tests use strong extracts, not a cup of tea.
So a normal tea may never reach those levels in your body. Treat the lab work as a hint, not an answer.
In Chinese medicine terms the herb is cold and bitter. It is used to clear heat from the skin, throat and eyes. That is a traditional idea, not a lab result.
Loose dried flowers are the most common form. You can simmer them in water or steep them like a herbal tea.
Granules and powders that dissolve in water are also sold. Some Chinese patent pills and suppositories include it along with other herbs.
It is used on the body too. A cooled, strong tea can be used as a skin wash or as a compress on closed eyelids.
A steam-distilled essential oil is also sold. Never swallow it. It is far too strong to take by mouth.
Chinese herb books have listed Ye Ju Hua since about the 1500s. Older texts grouped it with garden chrysanthemum, called Ju Hua.
Today the two are treated as separate herbs. Ju Hua is milder and is aimed at the eyes and head. Ye Ju Hua is colder and is aimed at boils, sores and a hot sore throat.
It is a staple of one tradition, Chinese medicine, rather than many. It still appears in the Chinese Pharmacopoeia, China's official drug list.
Some reactions to Ye Ju Hua need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Call emergency services right away if your face, lips or tongue swell, if a rash spreads fast, or if you have trouble breathing. That is a severe allergic reaction.
See a doctor the same day if a boil grows, throbs or leaks pus, if red streaks spread from it, or if you get a fever or shivering.
Also see a doctor the same day for eye pain, blurred sight, or light hurting your eyes. Get help soon if a sore throat stops you swallowing or drinking.
Book a normal appointment if nothing has improved after two weeks, or if the tea gives you lasting stomach ache or loose stools.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Ye Ju Hua 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.
