What is Ge Xia Zhu Yu Tang?
Ge Xia Zhu Yu Tang is a Chinese herb formula. Its English name is Drive Out Blood Stasis Below the Diaphragm Decoction. It is counted as one single drug, even though it holds about eleven herbs.
In Chinese medicine it is used for pain that stays in one spot below the ribs. It is also used for hard lumps in the belly that you can feel. A trained herbalist gives it as a short course, not as a daily tonic.
Here is the short verdict. The formula has been in steady use in China for nearly 200 years.
But we found no sound human trials for it, and long use is not proof that a thing works. That point is made here once and not repeated below.
How does Ge Xia Zhu Yu Tang work?
The idea behind it is simple. Chinese medicine holds that pain which sits in one fixed spot comes from stuck blood. The herbs are said to get that blood moving and ease the pain.
That is a traditional idea, not a proven body process. No study has shown what the whole mix does inside a person.
Lab work on single herbs in the mix hints at a few effects. Safflower and peach kernel can thin the blood a little. Corydalis eases pain in animal tests.
We do not know if any of that happens at the doses people actually take. Treat the thinning effect as real enough to plan around, since it shapes the safety advice below.
What forms does Ge Xia Zhu Yu Tang come in?
You may meet it in four forms.
A decoction (a tea boiled from raw herbs) is the classic form. It tastes bitter and is made fresh.
Granules are dried extracts you stir into hot water. They are the most common modern form.
Pills and capsules are sold ready made. The herb amounts in them vary a lot by brand.
A liquid tincture is less common in this tradition. Herb quality and labelling are not tightly checked in many countries, so buy from a supplier who tests for heavy metals.
Where it comes from:
The formula comes from Yi Lin Gai Cuo, a Chinese medical book from 1830. The author, Wang Qingren, wrote a set of blood-moving formulas, and this is one of them. Each formula targets a different part of the body, and this one targets the area below the diaphragm (the sheet of muscle under the ribs).
It has stayed in steady use in Chinese herbal practice since then. It is taught in modern Chinese medicine schools and listed in standard formula texts.
Who should avoid Ge Xia Zhu Yu Tang?
- Do not use if you are pregnant, might be pregnant, or are trying for a baby. This is an absolute ban: the formula can cause bleeding and loss of the pregnancy, and there is no safe dose.
- Do not use if you are breastfeeding, because no one knows what passes into breast milk.
- Do not use if you take warfarin, apixaban, rivaroxaban, heparin or any other blood thinner.
- Do not use if you take aspirin, clopidogrel or another drug that stops clots forming.
- Do not use if you have a bleeding disorder such as haemophilia (an inherited problem with clotting).
- Do not use if you are bleeding now, including a peptic ulcer (a sore in the stomach lining), blood in your stool or urine, or blood when you cough.
- Do not use if you have surgery, a dental operation or a biopsy coming up in the next two weeks.
- Do not use if you have heavy or unexplained vaginal bleeding that a doctor has not looked into.
- Do not use if you have high blood pressure, heart failure, kidney disease or low potassium (a blood salt), because of the licorice in the mix.
- Do not use if you take digoxin (a heart drug) or water pills (diuretics, which make you pass more urine).
- Do not use if you have found a lump or have belly pain that no doctor has checked yet. Get a diagnosis first.
- Do not use if you are allergic to any herb in the mix, or to plants in the daisy family such as safflower.
- Never give it to a child unless a doctor and a trained herbalist are both guiding the care.
When should you see a doctor?
Call emergency services now if you vomit blood, pass black tarry stools, or have bleeding that will not stop.
Get help the same day if you have a bad headache, blurred vision, chest pain or an odd heartbeat.
See a doctor soon if you bruise easily, get nosebleeds, or your periods turn much heavier.
See a doctor soon if your face or ankles swell, or your muscles feel weak. That can mean the licorice is affecting you.
Stop and get advice if a lump grows, you lose weight without trying, or belly pain gets worse. Stop the formula before any planned operation and tell the surgeon what you took.
