Gua Lou Xie Bai Bai Jiu Tang is a classical Chinese herbal decoction (a tea made by simmering herbs) used for a tight, heavy, aching chest. Its English name is Trichosanthes Fruit, Chinese Chive, and Wine Decoction. It is catalogued here as a single drug entry, even though it is a formula of three parts.
The three parts are Gua Lou (the whole fruit of Trichosanthes), Xie Bai (the small bulb of Chinese chive, a relative of garlic and onion), and Bai Jiu, a clear rice wine. The wine is part of the recipe, not an optional extra, so every dose contains alcohol.
In Chinese medicine it is given for what is called chest bi, meaning chest painful obstruction: pressure or pain behind the breastbone, shortness of breath, coughing and a feeling of fullness. In modern terms, people have used it alongside care for angina (chest pain caused by poor blood flow to the heart) and for phlegm-heavy breathing problems.
On the evidence: this formula has a long and unbroken record inside one tradition, but good human trial evidence in English is very thin, and traditional standing is not proof that something works. Chest pain has serious causes. This formula is not a treatment for a heart attack and must never be used to wait one out.
The honest answer is that nobody has shown clearly how it works in people, and the explanations below are theory rather than proven fact.
In classical Chinese medicine, the chest pain it treats is blamed on cold and phlegm blocking the yang (the warming, moving energy) of the chest. Gua Lou is said to loosen phlegm and open the chest, Xie Bai to warm and unblock, and the wine to carry the herbs and move blood.
Laboratory and animal work suggests some plausible activity. Trichosanthes extracts have shown effects on platelets (the blood cells that form clots) and on fat build-up in vessel walls in test tubes and rodents. Allium macrostemon, the chive bulb, contains sulphur compounds similar to those in garlic, which relax blood vessels in the laboratory.
None of that has been confirmed to produce a meaningful effect in the human heart. Alcohol itself widens blood vessels and can briefly ease a feeling of tightness, which may account for part of what people notice.
Most people meet it as a decoction — the raw herbs simmered in water and wine, then strained and drunk warm. This is the classical form and the one the original text describes.
Other forms sold today:
Granules or concentrated powder that you stir into hot water.
Pills or capsules made from dried extract.
Pre-made liquid bottles.
Manufactured versions often leave the alcohol out or use only a trace. Read the label, because an alcohol-free product is a different thing from the classical recipe and may act differently.
The formula comes from the Jin Gui Yao Lue (Essentials of the Golden Cabinet), written by Zhang Zhongjing around the early third century CE.
It has been taught, copied and prescribed continuously since then, and it is the parent of a small family of related formulas that add half-summer (Ban Xia) or other herbs for heavier phlegm.
It is a fixture of Chinese medicine teaching but has no independent record in other traditions.
Some reactions to Gua Lou Xie Bai Bai Jiu Tang 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 now if you have chest pain that is crushing or severe, pain spreading to the arm, neck or jaw, cold sweating, sudden breathlessness, fainting, or a fast or irregular heartbeat. These can be signs of a heart attack, and no herb is a substitute for emergency care.
See a doctor soon if your chest tightness keeps coming back, gets worse on exertion, wakes you at night, or has not improved after about two weeks.
Stop the formula and get advice if you get a rash, swelling of the face or lips, trouble breathing, ongoing vomiting, severe diarrhoea, yellowing of the skin or eyes, or unusual bruising or bleeding.

The published evidence for Gua Lou Xie Bai Bai Jiu Tang 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.
