Cheollyeonja
Do not self-treat with Cheollyeonja
Practitioner-prepared only. In Korean and Chinese clinical practice, a licensed practitioner typically uses 3 to 10 grams of the dried fruit per day inside a decoction of several herbs.
If this is an emergency
Some reactions to Cheollyeonja 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 Cheollyeonja?
- Do not use if you are pregnant or trying to become pregnant: this is an absolute ban, at any dose.
- Do not use if you are breastfeeding.
- Do not use if you are buying it for a child or teenager; never give this fruit to a child, as chinaberry fruit has poisoned and killed children.
- Do not use if you have any liver problem, including hepatitis (liver inflammation), fatty liver or cirrhosis (long-term scarring of the liver).
- Do not use if you drink alcohol heavily or daily.
- Do not use if you take medicines known to strain the liver, such as paracetamol (acetaminophen) regularly, methotrexate, isoniazid or antifungal tablets.
- Do not use if you have a heart-rhythm problem such as bradycardia (a slow heartbeat) or heart block, or take digoxin or beta-blockers.
- Do not use if you have kidney disease.
- Do not use if you have a peptic ulcer (a sore in the stomach lining) or inflammatory bowel disease.
- Do not use if you have epilepsy or any seizure disorder.
- Do not use if you cannot get it from a licensed practitioner who will check your liver — never self-dose this herb or buy it online to use alone.
- Do not use if you have picked the fruit yourself from an ornamental chinaberry tree.
When should you see a doctor?
Stop taking it and get medical help straight away if your skin or the whites of your eyes turn yellow, your urine turns dark, your stools turn pale, or you get pain under your right ribs. These can be signs of liver injury.
Call emergency services if you or anyone else has vomiting that will not stop, a very slow or irregular heartbeat, muscle weakness, trouble breathing, confusion, a seizure (fit) or collapse after taking this herb, or if a child has eaten any chinaberry fruit. Take the packet or the plant with you if you can.
See a doctor before using it at all if your belly pain is severe, keeps coming back, wakes you at night, or comes with fever, vomiting or blood in your stool. Sudden severe groin or testicle pain is an emergency and needs same-day care.

What is Cheollyeonja?
Cheollyeonja is the dried ripe fruit of the tree Melia toosendan. It is also called Sichuan chinaberry fruit. Only a trained practitioner should give it, and it is not a home remedy.
Korean herbal medicine uses it inside formulas, never on its own. These formulas treat cramping belly pain, and pain in the groin and testicles. It is also used to clear worms from the gut.
This fruit is toxic. It can harm the liver and upset the stomach and gut. Larger amounts can affect heart rhythm, muscle strength and breathing.
People have been poisoned after taking too much, and some have died.
Evidence verdict: the fruit has long standing in East Asian medicine. But no sound human trials back it up.
Long use in tradition is not proof that a substance works or that it is safe. That point applies to everything below.
How does Cheollyeonja work?
No one has shown, in people, how this fruit does what tradition claims. What follows is theory. It comes from lab work and from old texts.
In Korean and Chinese medical theory, the fruit is bitter and cold. It is said to move stuck "liver qi" (a traditional idea of blocked flow, not a measured body process).
It is also said to drain heat. That is why it turns up in formulas for cramping pain that comes in waves.
Its main compound is toosendanin. In the lab, this blocks signals where nerves meet muscle. It is also toxic to some worms and insects.
That same action is a big part of why the herb is dangerous at high doses. No dose has been shown to be useful or safe in people.
What forms does Cheollyeonja come in?
Cheollyeonja is almost never used alone. You will meet it as one part of a multi-herb prescription.
Common forms include:
Dried whole or sliced fruit, simmered in water with other herbs to make a decoction.
Dry-fried or vinegar-treated fruit. This is done to make it less harsh on the stomach.
Powders and honey pills made up by a licensed practitioner.
Strong extract granules, given out in Korean and Chinese herbal clinics.
Avoid raw fruit sold loose as a curiosity. Never eat fruit picked from an ornamental chinaberry tree (one grown for looks).
Where it comes from:
Cheollyeonja came into Korean practice from classical Chinese medicine. There it is known as chuan lian zi. Chinese herb texts list it as far back as about two thousand years.
Korean books of the Joseon period list it too. They include the Donguibogam of 1613. It was used there for cramping pain and for worms.
The fruit is also used in Japanese kampo and in Vietnamese folk medicine. So its classical footprint crosses several East Asian traditions.
All of them treat it as a strong, somewhat toxic herb. It is meant to be used briefly and with other herbs.
What does Cheollyeonja help with?
- Cramping pain in the belly or sides: This is the main classical use, and it rests on tradition alone. Korean and Chinese formulas pair cheollyeonja with corydalis (yeonhosaek) for pain that grips and releases in waves. No controlled human trial has tested whether the herb relieves this pain better than a dummy treatment.
- Groin, testicle and hernia-type pain: Old texts single this out as the herb's special area, often in formulas for pain that runs down into the groin. There is no human trial evidence. Any swelling or sudden severe pain in the groin or testicle needs urgent medical assessment, not a herb.
- Intestinal worms: The fruit and the bark of related Melia trees were used to expel roundworms long before modern medicines existed. Laboratory work shows toosendanin is toxic to some parasites. Modern anti-worm tablets are far safer and far more reliable, and doctors do not recommend the herb for this.
- Pain described in tradition as coming from stuck liver qi: This is a traditional pattern label, not a medical diagnosis. It covers pain, irritability and tight ribs that a practitioner reads as blocked flow. No modern research has tested the herb against this pattern in people.
What are the side effects of Cheollyeonja?
- Nausea and vomiting
- Stomach pain and cramping
- Diarrhoea
- Dizziness and headache
- Drowsiness or unusual tiredness
- Liver injury, which may show as yellow skin or eyes, dark urine, pale stools or pain under the right ribs
- Slow or irregular heartbeat in overdose
- Muscle weakness, trouble breathing, confusion or seizures (fits) in serious poisoning
Good to know:
Stomach upset is common, even at traditional doses. Liver injury and nerve and heart effects are rare but serious, and they have caused deaths after overdose.
Risk rises sharply with larger amounts, longer use, and use in children. Children are especially vulnerable to chinaberry poisoning.
Stop taking it and get medical help if you notice yellow skin or eyes, dark urine, repeated vomiting, a racing or very slow heartbeat, weakness or trouble breathing.
Options to discuss with a clinician
For each of the problems this remedy is reached for, there are routes that have been studied far more thoroughly — and every one of them starts as a conversation with a doctor, pharmacist or qualified herbalist rather than something you pick up and take.
**Cramping pain in the belly or sides.** This is a symptom with many possible causes, from gallstones to bowel conditions to ulcers, and the treatment that works depends entirely on which one it is. A GP can arrange the tests that tell them apart, and there are established prescription and over-the-counter options for cramping once the cause is known.
**Groin, testicle or hernia-type pain.** Pain in these areas needs same-week assessment, and sudden severe testicular pain is an emergency — a twisted testicle (testicular torsion) can be saved only within hours. Hernias are repaired surgically; no remedy closes one.
**Intestinal worms.** Modern anti-parasite medicines are cheap, short-course and very well mapped for safety. A pharmacist can supply some directly; a GP can test a stool sample to identify which parasite is present.
**Pain traditionally described as stuck liver qi.** A registered herbalist can discuss what their tradition offers for this pattern, and can do so knowing your diagnosis and your other medicines.
