What is Bai Ji?

Bai Ji is the dried rhizome (an underground stem) of a small orchid, Bletilla striata. In Chinese medicine it is used to stop bleeding and to help raw or cracked skin close over. It is a single herb, not a blend.

It is taken as a tea or powder for coughing up or vomiting blood. It is also dusted or pasted on cuts, burns, chapped hands and slow-healing sores.

Here is the short verdict on evidence. Bai Ji has a long, steady place in Chinese herbal practice, but good human trials are almost absent. Long use in a tradition is not proof that a herb works, and that holds for every claim on this page.

How does Bai Ji work?

The best-supported idea is a simple physical one. The root is full of a sticky gum that swells in water and forms a gel. On a raw surface, that gel may coat the area and help a clot hold.

Lab and animal work suggests the gum can shorten the time blood takes to clot and can act as a soft wound dressing. Whether the same thing happens when you swallow it is not clear.

In Chinese medicine terms, Bai Ji is said to be sweet, bitter and astringent, and to "stop bleeding and close sores". That is a description of how it is used, not a proven body mechanism.

What forms does Bai Ji come in?

You will most often meet Bai Ji in these forms:

- dried sliced root, boiled into a tea - fine powder, taken by the spoon with water - powder mixed into a paste and put on the skin - ready-made granules or pills that hold a mix of herbs

Bai Ji is also used in some wound dressings and gels made in China. In Western shops it is sold mainly as loose root or powder.

Where it comes from:

Bai Ji appears in the Shen Nong Ben Cao Jing, a Chinese herb text from roughly two thousand years ago. It has stayed in use ever since.

Classic texts group it with herbs that stop bleeding. It was given for spitting blood from the lungs, for blood in vomit, and for sores, burns and cracked skin.

Old texts also warn that Bai Ji must never be combined with aconite herbs. That warning is part of a classical list of herb pairs treated as unsafe.

What does Bai Ji help with?

• Coughing up blood: This is the classic use in Chinese medicine, and the herb has been given this way for centuries. There are no good published human trials in English that test it for this. Coughing up blood always needs a doctor, because the cause matters more than the bleeding.
• Vomiting blood or bleeding in the stomach: Chinese hospitals have used Bai Ji powder for bleeding from the stomach lining, often alongside standard care. Reports are mostly small and not blinded, so they cannot rule out chance or placebo. Bleeding from the stomach is a medical emergency, not a home-treatment problem.
• Minor cuts and scrapes: The powdered root forms a gel on damp skin, which may hold a clot in place. This use is well established in tradition and is the most believable of its uses. Use it only on small, clean wounds.
• Minor burns and chapped, cracked skin: Bai Ji paste is a traditional dressing for chapped hands, chapped lips and small surface burns. Modern work on Bletilla gum as a wound dressing is mostly laboratory and animal work. Deep, large or blistering burns need a doctor, not a herb.
• Slow-healing skin sores: Traditional texts pair Bai Ji with herbs that drain pus for sores that will not close. Human evidence is thin. A sore that is spreading, hot or leaking pus needs medical care.
• Nosebleed: Folk use includes packing the nose with the powder. There are no trials to support this. Pressure, ice and a doctor's help are the safer path for a nosebleed that will not stop.

Which foods are rich in Bai Ji?

The starch from Bletilla is used in a few regional Chinese sweets and drinks, but not in amounts used as medicine.

What are the side effects of Bai Ji?

• Nausea or an upset stomach
• A thick, gluey feeling in the mouth or throat from the powder
• Loose stools or, in some people, constipation
• Skin redness or itching where the paste was applied
• Rare allergic reaction, with rash, swelling or trouble breathing

Good to know:

Most people who use Bai Ji have no trouble with it. Side effects are usually mild and stop when you stop the herb.

The powder is very sticky. Swallowing it dry can make you gag, so mix it into water first.

There is no good safety data for long-term use, for children or for pregnancy. Treat it as a short-term herb, and stop it if anything unusual starts.

How much Bai Ji should you take?

• Recommended daily: No dose has been set by any drug regulator, so the numbers below come from Chinese herbal practice. Dried root boiled into a tea: about 3 to 10 grams a day. Powder taken by mouth: about 1.5 to 3 grams a day, split into two or three doses. Powder on the skin: enough to dust a clean, small wound. Start at the low end. Do not use Bai Ji for internal bleeding on your own.
• Best time of day: Spread the daily amount over two or three doses. For stomach complaints, practitioners often give it between meals. On the skin, apply after gently cleaning the area.
• With or without food: Either works. Taking it with a little food or warm water may be kinder to your stomach, since the powder is thick and sticky.
• Time to effect: On a small cut, the powder acts within minutes to form a gel. For internal use, traditional practice expects some change within a few days. No trial has measured either.
• How long to take it: Bai Ji is meant for short use, not as a daily supplement. Most traditional courses run days to a few weeks. Reassess after about two weeks. If the bleeding, sore or cracked skin has not improved, stop and see a doctor. There is no safety data on taking it for months on end.
