Track Zhu Ma Gen with reminders and record whether it helped, in the app.
Zhu Ma Gen is the root of the ramie plant. Ramie is a tall fibre plant grown in China and much of Asia. The herb is also called ramie root, or boehmeria root.
It is a single drug, used on its own as one herb in Chinese medicine. Healers use it to cool heat in the body and to slow bleeding. The best known old use is for bleeding in pregnancy.
Modern proof is thin. We found no human trials of this root on its own. Long use in a tradition is not proof that a herb works.
No one has shown how this root works in the body. Lab tests point to a few effects, but lab work is not proof in people.
In Chinese terms, the root is cold and sweet. It is said to cool the blood, stop bleeding, and calm a restless fetus (an unsettled baby in the womb). Those are ideas from an old system, not lab findings.
Some lab work on ramie root looks at clotting, at swelling, and at germs. The doses used in a dish are not the doses a person drinks.
The dried root, cut into slices, is the main form. You simmer it in water to make a decoction (a strong herbal tea).
You may also see it as a loose powder, or as granules that melt in hot water. It is often one item inside a mixed formula rather than a stand-alone product.
Fresh root juice was used in the past. Fresh juice is hard to judge for strength, so it is rare today.
Chinese herb books have listed this root for about 1,500 years. It shows up in early plant texts and again in the Ben Cao Gang Mu of the Ming era.
Its main old job was to steady a pregnancy and to check bleeding. Healers also laid the mashed root on hot, sore skin.
Ramie itself is a very old crop. People grew it for cloth long before the root was used as a herb.
Get medical help the same day if you bleed while pregnant, even a small amount. Go to an emergency department if the bleeding is heavy, or if you have belly pain, dizziness or fainting.
See a doctor if you have blood in your urine, blood when you cough, or a nosebleed that will not stop after 20 minutes of firm pressure. See a doctor too if your periods get heavier or last longer than usual.
Stop the herb and get help at once if you get a rash, swelling of the face, lips or tongue, or trouble breathing.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Zhu Ma Gen 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.
