What is Ji Gu Cao?
Ji Gu Cao is a single herb used in Chinese medicine. It is made from the dried above-ground parts of the Canton love-pea vine (Abrus cantoniensis). In southern China it is known as a liver herb and as a soup ingredient at home.
Healers give it for what they call damp-heat in the liver and gallbladder. The signs they treat include yellow skin and eyes. They also treat a heavy, dull ache under the right ribs, plus an upset stomach.
It is also used in tradition for sore, swollen breasts during breastfeeding.
Here is the honest verdict on the evidence. This herb has centuries of folk and clinic use in one region, but good human trials are lacking. Long use is not proof that a herb works, and nothing here is a promise of benefit.
One safety point belongs up front. Abrus seeds hold abrin, a violent poison, and people have died after seed poisoning. Only the stem and leaf, with no seeds, is used as medicine.
How does Ji Gu Cao work?
The short answer: no one has shown clearly how Ji Gu Cao works in people. The usual explanations come from lab and animal studies.
In TCM terms, the herb is said to clear heat, drain damp and soothe the liver. That is a way of sorting symptoms. It is not a description of body chemistry.
Lab work hints that extracts may lower inflammation (swelling and soreness). In animals, they may shield liver cells from some chemical harm. Some plant compounds also seem to change bile flow in animals.
These are early findings in dishes and rodents. They do not tell you what happens in a person with hepatitis (liver inflammation).
The liver is the very organ people take this for. Liver problems can get worse quietly. So none of this is a reason to put off medical tests.
What forms does Ji Gu Cao come in?
Ji Gu Cao is sold and used in a few simple forms.
- Dried cut herb (stems and leaves), boiled into a decoction; this is the usual traditional form - Soup packets from Cantonese groceries, often mixed with dried meat, beans or jujube - Granules and instant powders made from a water extract - Patent medicines and "liver tonic" tablets that list it with other herbs - Bottled herbal teas in parts of southern China and Hong Kong
Quality varies a lot. Buy from a seller who names the species on the label. Check that the label confirms the seeds have been removed.
Where it comes from:
Ji Gu Cao is a Lingnan herb. Lingnan means the far south of China, around Guangdong and Guangxi. The vine grows wild there.
It shows up in regional herb books and folk practice from about the 1800s onward. It is not in the ancient classic texts. In the 1900s it entered modern Chinese drug lists and hospital use.
It is still a household item in Cantonese cooking. The seed-free vine is simmered for hours into a soup. People take that soup for "heatiness" and hangovers.
Who should avoid Ji Gu Cao?
- Never eat, chew or brew the seeds or seed pods of any Abrus plant — they contain abrin, a violent poison, and people have died from swallowing them.
- Do not use if you are pregnant or trying to become pregnant, as safety has not been established.
- Do not use if you are breastfeeding, unless a qualified practitioner who knows the herb advises it.
- Do not give it to children.
- Do not use if you have a liver disease that is being treated, unless your doctor approves it, and never in place of antiviral medicine for hepatitis B or C.
- Do not use if you have had a liver or kidney transplant or take immunosuppressants (medicines that damp down the immune system).
- Do not use if you take warfarin or another blood thinner without having your clotting checked more often.
- Do not use if you have had an allergic reaction to Abrus plants or to legumes such as peas and beans.
- Avoid it if you are already taking several medicines processed by the liver, until a pharmacist has reviewed the combination.
- Do not buy material you cannot identify: the related plant Abrus precatorius (jequirity bean) has far more dangerous seeds and is sometimes confused with it.
When should you see a doctor?
Stop taking it and see a doctor promptly if your skin or the whites of your eyes turn yellow, your urine goes dark, your stools turn pale, or you feel unusually tired or itchy all over. These can mean the liver is struggling.
See a doctor within a day if you have a painful, red, hot breast with fever while breastfeeding, or steady pain under your right ribs.
Go to an emergency department at once if anyone has swallowed the seeds or pods, or if there is burning in the mouth and throat, repeated vomiting, bloody diarrhoea, confusion or collapse. Take the packet with you.
Also tell your doctor you are taking it before any surgery or new prescription.
