Chokeito is a Japanese Kampo herb tea for urine problems. People take it when peeing burns, stings or is hard to start. It is also used for needing to pee often or in a rush.
The Latin name is Polyporus decoction. A decoction is a tea made by boiling. Some lists call it a single herb, but that is not right.
It is a set formula of five parts. Polyporus mushroom is only the lead one. The others are poria mushroom, alisma root, talc (a soft mineral powder) and gelatin from animal hide.
The tradition here is old and wide. The proof is thin. Long use in Kampo is not proof that a medicine works, and this document does not treat it as proof.
The short answer: no one has shown how it works in people.
In Kampo, Chokeito is said to clear "damp heat" from the water pathway of the body. In plain words, it is meant to cool and flush a sore, hot bladder. That is a traditional idea, not a tested one.
Modern lab and animal work hints at a mild water-pill effect. A water pill makes you pee more. Alisma root and polyporus raised urine flow in animals, but that does not prove it eases bladder pain in people.
It does not kill germs. So it is not a stand-in for antibiotics when you have a urine infection.
Most people use dried extract granules. You stir them into warm water and drink them. In Japan these granules are a listed medicine and are often given by a doctor.
You can also buy tea bags or packs of the raw cut herbs. You boil these in water and drink the strained tea warm.
Tablets and capsules exist too. They are easier to carry but often give a smaller dose per serving. Check the label for the daily amount.
Chokeito came from a Chinese text, the Shanghan Lun, written about 1,800 years ago.
Japanese doctors took it up and kept it. It is still one of the standard Kampo mixes used in Japan today, mostly for bladder and urine complaints. Korean and Chinese practice use it as well, under the name Zhu Ling Tang.
See a doctor the same day if you get a fever, chills, pain in your back or side, or if you are being sick. Those can be signs the infection has reached your kidneys.
See a doctor soon if there is blood in your urine, if you cannot pee at all, or if nothing is better after three days.
Stop the tea and call a doctor if your skin or the whites of your eyes turn yellow, if your urine goes dark, or if you get a rash that spreads. Get emergency help if your lips or face swell or you struggle to breathe.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Chokeito 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.
