Notopterygium

Notopterygium incisum · also called Qiang huo, qianghuo, notopterygium root

Notopterygium (qiang huo) is a root and rhizome used in Chinese medicine for aching joints, colds with chills and headache. Two small trials tested multi-herb formulas that include it, but none tested the root on its own, so the evidence is weak. It contains furanocoumarins that may affect some medicines and, possibly, sun sensitivity. Avoid it in pregnancy and ask a doctor or pharmacist first.

About Notopterygium

Notopterygium (qiang huo) is the dried root and rhizome of a high-altitude Chinese plant of the carrot family. It is used in Chinese medicine for aching joints from wind and damp, and for colds with chills and headache. Two small trials tested formulas that include it, with very low certainty, and no trial tested the root alone. It contains notopterol, a furanocoumarin that blocked a drug-clearing enzyme in a test tube. Avoid it in pregnancy and breastfeeding, and ask a doctor or pharmacist about blood thinners, other medicines and amounts.

What it is

Qiang huo is the dried rhizome and root of Notopterygium incisum and a close relative, N. franchetii. Both belong to the carrot family (Apiaceae) and grow on high ground in western China.

Botanists now file them under the genus Hansenia, so you may see different Latin names on labels. Two species are sold as qiang huo, and wild plants are being replaced by cultivated ones.

What makes it distinctive

More than 500 compounds have been found in the plant, mostly in the root. The best known are coumarins, especially the furanocoumarins notopterol and isoimperatorin.

Furanocoumarins are the same plant-chemical family that makes parsnip sap sensitise skin to sun, which is why sun sensitivity is a precaution here. Notopterol also blocked the drug-clearing enzyme CYP2D6 in a test tube.

Historical and current uses

Chinese medicine describes qiang huo as pungent, bitter and warm. It is used to disperse cold, ease wind-cold-damp joint pain, and relieve colds with chills and headache.

It is mostly used in formulas such as Jiuwei Qianghuo Decoction. Many pages group it with du huo (Angelica pubescens), fang feng (Saposhnikovia) and chuanxiong, which are used in similar patterns.

What the research shows

Two small Chinese trials tested multi-herb formulas that include qiang huo. One in 90 people with rheumatoid arthritis found a response similar to methotrexate. One in 50 people with spondyloarthritis found a better response when a 15-herb recipe was added to celecoxib. Neither could show what qiang huo does by itself.

The rest is lab and animal work: anti-inflammatory activity in zebrafish, a formula in flu-infected mice, and notopterol against liver cancer cells. This is not proof of benefit in people.

Rheumatoid arthritis (in a multi-herb formula)

Very low certainty

One 24-week trial of a qiang huo-containing formula in 90 people with rheumatoid arthritis found it worked about as well as methotrexate, with fewer side effects reported. It is a formula, so qiang huo cannot be credited alone.

2 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

One randomised trial (90 people, 24 weeks, Shanghai) of Shenshi Qianghuo Dihuang Decoction against methotrexate. Qiang huo is one named herb in the formula name; the abstract does not list the contents.

Results

Response rate (ACR20) was reported as 62.53% with the formula and 67.5% with methotrexate, with no statistical difference. Methotrexate was better for rest pain and joint tenderness. Adverse reactions were 9.75% (formula) vs 32.5% (methotrexate).

Effect sizes as reported

ACR20 62.53% vs 67.5% (P>0.05); adverse reactions 9.75% vs 32.5% (P<0.05)

Why this rating

Single-centre trial in Chinese, no placebo, formula not itemised, and the reported 62.53% does not match 24/41, so the numbers are shaky. Methotrexate was the comparator, not placebo.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Adults with rheumatoid arthritis in one Chinese hospital.

Limits

Cannot show what qiang huo alone does. No placebo. Odd arithmetic in the abstract.

Why researchers looked

Aching, stiff joints thought to come from wind and damp are the classic reason qiang huo is used in Chinese medicine.

Traditional use

Chinese medicine uses qiang huo for wind-cold-damp painful obstruction and rheumatoid arthritis (2017 review).

Proposed mechanism Animal / pharmacological theory

No mechanism is shown in people. Lab studies report anti-inflammatory and analgesic activity of its coumarins.

A proposed mechanism does not show that the effect happens in people.

Rheumatoid arthritis needs proper medical treatment. Do not replace prescribed medicines with a herb. See the safety tab for interactions.

3 1

Axial spondyloarthritis (add-on, in a 15-herb mix)

Very low certainty

In a small 4-week trial, a 15-herb recipe that includes notopterygium, added to celecoxib, gave a higher response rate than celecoxib alone. Many herbs were mixed, so nothing can be credited to qiang huo.

1 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

One small randomised trial (54 enrolled, 50 completed, 4 weeks) of Qiangji Recipe plus celecoxib vs celecoxib alone.

Results

ASAS20 response at week 4: 76.92% (20 of 26) with the recipe plus celecoxib vs 50.00% (12 of 24) with celecoxib alone. No obvious adverse reactions were reported in either group.

Effect sizes as reported

76.92% vs 50.00% (P<0.05)

Why this rating

Small, 4 weeks, open design, 15 herbs in one recipe, in Chinese, funding not stated.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Adults with axial undifferentiated spondyloarthritis (a Chinese-medicine pattern called kidney-deficiency, Du-channel cold).

Limits

Cannot credit qiang huo. Short follow-up.

Why researchers looked

Back and joint stiffness is another wind-cold-damp pattern that Chinese medicine treats with qiang huo-containing recipes.

Traditional use

Used in formulas for wind-cold-damp painful obstruction (2017 review).

Proposed mechanism Pharmacological theory

Not established.

A proposed mechanism does not show that the effect happens in people.

Celecoxib is a pain medicine with its own risks; ask a doctor or pharmacist before adding any herbal mix.

Joint and body aching (traditional use)

Not enough evidence

Qiang huo root is a long-standing Chinese remedy for aching joints from wind and damp. Traditional teaching often links it to the upper body and neck; we could not confirm that detail in the abstracts we read. We found no trial of the root on its own.

3 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

No trial of the root alone for joint pain was found. Human evidence is limited to the two formula trials above.

Results

Evidence is traditional use plus lab and animal findings.

Effect sizes as reported

None

Why this rating

Tradition and lab work only. The upper-body emphasis is not verified here.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Not studied as a single herb in people.

Limits

Formulas mix many herbs. The upper-body detail is not confirmed.

Why researchers looked

It is one of the standard herbs for wind-damp joint pain in Chinese medicine.

Traditional use

A 2025 study calls the dried rhizome a classic herb for wind-dampness arthralgia; a 2017 review lists headache, rheumatoid arthritis and colds among its uses.

Proposed mechanism In vitro / animal

Lab work on coumarins, mainly notopterol and isoimperatorin, suggests anti-inflammatory and pain-modifying actions.

A proposed mechanism does not show that the effect happens in people.

Furanocoumarin-containing herbs can interact with medicines and sun. See the safety tab.

Colds with chills, and headache (traditional use)

Not enough evidence

Qiang huo is traditionally used to disperse cold and ease colds with chills and headache. We found no human trial of it for these uses.

2 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

No human trial of qiang huo for colds or headache was found.

Results

Evidence is traditional use only.

Effect sizes as reported

None

Why this rating

Tradition only; the lab findings are not human evidence.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Not studied in people.

Limits

No human data.

Why researchers looked

Chinese medicine describes it as a herb that disperses cold from the outer body.

Traditional use

Used for wind-cold exterior syndrome, headache and as a sweat-inducing herb (2017 review).

Proposed mechanism Animal research

Reviews list antipyretic and analgesic effects in lab and animal work. See the other tab for a mouse flu study of a formula.

A proposed mechanism does not show that the effect happens in people.

A cold that does not improve, or fever with breathing trouble, needs a doctor.

1 14

Inflammation (zebrafish and lab work)

Not enough evidence

Extracts of the dried rhizome, rich in coumarins, calmed inflammation in zebrafish embryos. This is lab work only.

2 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

No human study.

Results

Both wild and cultivated rhizome showed an anti-inflammatory effect in a zebrafish yolk-sac model.

Effect sizes as reported

No numbers in the abstract

Why this rating

Zebrafish embryos are far from people.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Not studied in people.

Limits

Wild and cultivated plants differ in chemistry. Lab model only.

Why researchers looked

Researchers want to explain the traditional use for painful, swollen joints.

Traditional use

Used for wind-dampness arthralgia.

Proposed mechanism Animal research

Coumarins and phenolic acids were the most abundant compounds; the extract changed inflammatory gene expression and neutrophil counts in zebrafish.

A proposed mechanism does not show that the effect happens in people.

Not a treatment.

Severe influenza (multi-herb formula in mice)

Not enough evidence

A formula containing qiang huo improved survival signals in mice with a lethal flu infection when started late. It was a mouse and cell study of a multi-herb mix.

1 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

No treatment trial in people. Immune cells from patients with H1N1 were used only for a cell-death test.

Results

In mice, the formula was most effective when given 48 hours after infection and lowered inflammatory signals in the lungs.

Effect sizes as reported

No numbers in the abstract

Why this rating

Mouse and cell work of a two-formula combination.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Mice and cell cultures.

Limits

Cannot credit qiang huo alone. Does not show benefit for flu in people.

Why researchers looked

Researchers wanted to know how a clinically prescribed qiang huo-containing combination works against severe flu.

Traditional use

The combination is described as clinically prescribed to stop flu getting worse.

Proposed mechanism Animal research

Cell experiments pointed to furanocoumarins as blocking TNF-alpha and IFN-gamma triggered macrophage death.

A proposed mechanism does not show that the effect happens in people.

Flu is a serious illness. Use proven care and ask a doctor.

16

Liver cancer cells (isolated notopterol, lab only)

Not enough evidence

Notopterol, a compound from the root, slowed human liver cancer cells in a dish and tumour grafts in mice. This is not a treatment.

1 studiesNot applicable: isolated compound, not the herb.

Studies, doses and limits

What the trials found

No human study.

Results

Notopterol reduced viability and movement of two liver cancer cell lines. In mice it slowed tumour growth more than sorafenib, without weight loss.

Effect sizes as reported

No numbers in the abstract

Why this rating

Dish and mouse work with an isolated compound.

Form and dose studied

Not applicable: isolated compound, not the herb.

Who was studied

Not studied in people.

Limits

Eating or taking the root is not the same as this compound. No human safety or benefit is shown.

Why researchers looked

Notopterol is the best-known furanocoumarin in the root, so it is tested for other effects.

Traditional use

Not a traditional use.

Proposed mechanism In vitro / animal

The compound raised oxidative stress in cancer cells and lowered cancer-stem-cell markers.

A proposed mechanism does not show that the effect happens in people.

Do not use qiang huo to treat cancer.

8

Blood clotting enzyme (test tube only)

Not enough evidence

Two compounds in the root, notopterol and isoimperatorin, blocked the clotting enzyme thrombin in a test tube. This is a lead, not a use. It is also a reason for caution with blood thinners.

2 studiesNot assessed. Traditional preparations and formulas vary, and no amou…

Studies, doses and limits

What the trials found

No human study.

Results

Notopterol and isoimperatorin inhibited thrombin in vitro.

Effect sizes as reported

IC50 59.35 and 107.8 micromolar

Why this rating

Test tube only.

Form and dose studied

Not assessed. Traditional preparations and formulas vary, and no amounts are given here.

Who was studied

Not studied in people.

Limits

No data on bleeding in people.

Why researchers looked

A 2024 review lists anticoagulant activity among reported effects, so researchers screened for the cause.

Traditional use

Not a traditional use.

Proposed mechanism Laboratory research

Both compounds inhibited thrombin in the test tube (IC50 59.35 and 107.8 micromolar).

A proposed mechanism does not show that the effect happens in people.

The evidence

The research centre for Notopterygium. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.

Evidence by outcome

Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).

How we rate evidence

High certainty

Several well-run trials or reviews agree; further research is unlikely to change the picture much.

Moderate certainty

Good trials point the same way, but some doubt remains.

Low certainty

Small, short or inconsistent trials. The finding could change with better research.

Very low certainty

Very little or very weak human data. Treat as a possibility only.

Mixed findings

Trials or reviews disagree with each other.

Not enough evidence

Not enough human research to say either way.

Evidence against

Good research found no benefit, or found harm.

We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We searched PubMed and looked for NIH NCCIH, LiverTox and regulator pages for Notopterygium. Most sources were abstracts only. Some details were carried over from an earlier summary and are marked. No study is cited that we could not verify.

Outcomes: ACR20 response; tender and swollen joints; ESR, CRP, anti-CCP; adverse reactions

Limitations: Multi-herb formula, so qiang huo cannot be credited alone. No placebo group, and blinding is not stated. 90 randomised but 41 and 40 analysed. The reported 62.53% does not match 24/41 (which is about 58.5%), so the numbers should be treated with caution. Published in Chinese, single centre.

Human enzyme test (test tube) Notopterol, isolated compound from Notopterygium rhizomes
isolated compound not stated in the abstract 9-minute incubation at 10 micromolar
Notopterol inhibited CYP2D6 in a time-, concentration- and NADPH-dependent way. About 92% of activity was lost after 9 minutes at 10 micromolar and was not restored by dialysis, so the block was irreversible. CYP3A4 was the main enzyme that processed notopterol. The authors say this may cause drug-drug interactions.
KI 10.8 micromolar; kinact 0.62 per minute
Methods, limits and funding

Outcomes: CYP2D6 activity

Limitations: Test-tube study with an isolated compound; no human data. Real-world effect depends on blood levels, which are not known.

What we do not know yet

  • No trial of qiang huo on its own was found for any use.
  • No human safety, liver, pregnancy or interaction study.
  • Sun sensitivity, gut upset and the yin-deficiency caution are untested or unsourced for this herb.
  • Only abstracts were read; the 2024 meta-analysis on cervical spondylosis has no abstract and was not used.
  • EMA/HMPC, WHO, LiverTox and LactMed entries were not found or not read.

How new research is added

New studies are found by a saved PubMed search and are placed in a review queue. A person reads each one before it changes any evidence rating or safety wording.

Lab markers

What changed in blood or saliva tests during trials. A changed number is not the same as feeling or being healthier, and we give no "normal ranges".

Safety

What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.

Main points to know 4
  • Almost no human safety data. We found no human safety study and no case report for qiang huo. A 2017 review says more research is needed on toxicology and on how the body handles the herb. Missing data is not proof of safety. Narrative review 1
  • It may change how some medicines are cleared. In a test-tube study with human enzymes, notopterol blocked CYP2D6 for good. In rats, two Kampo products containing notopterol did not clearly change a CYP3A drug but tended to lower a transporter drug. No human study exists, so talk to a pharmacist about any medicine you take. Laboratory 4 9
  • Sun sensitivity is unproven but possible. The root contains furanocoumarins, a plant-chemical family that includes sun-sensitising members in other plants such as parsnip. We found no study testing sun sensitivity for qiang huo. Treat it as a precaution, not a finding. Related species 8 10
  • Possible effect on clotting. Two compounds from the root blocked the clotting enzyme thrombin in a test tube, and a review lists anticoagulant activity in lab work. We found no bleeding report in people. Ask a doctor or pharmacist if you take blood thinners. Laboratory 2 14

Liver

No human case report of liver injury from qiang huo was found, and no LiverTox entry for it was confirmed. Notopterol is processed by the liver enzyme CYP3A4. The liver cancer study used liver cells as a cancer model, not as a safety test. 4 8 1

How often. Unknown in people.

Monitoring. No agency advice was found. If you have liver disease or take liver-affecting medicines, ask a doctor first. Stop and seek care for yellow skin or eyes, dark urine or severe tiredness.

This is a safety connection. It is not evidence that Notopterygium supports liver health.

Overdose, product quality and regulators

Summary. No human toxic amount and no animal LD50 for the root were found in the sources read. A 2017 review says toxicology needs more research.

Animal. No whole-root animal toxicity study was read. In mice, notopterol slowed tumour growth without adverse changes in body weight in one cancer study.

Human doses studied. No human safety study of the root alone was found.

High dose or long term signals. None found; this is absence of data, not safety.

Overdose response. Not described. Seek emergency help for any serious reaction.

Genotoxicity. Not assessed in the sources read.

Toxic plant parts. The root and rhizome are the medicinal part. Essential oil from the aerial parts was studied in the lab for antibacterial activity and cell toxicity (not read for this build).

Two related species are sold as qiang huo, wild plants are being replaced by cultivated ones, and wild and cultivated rhizomes differ in chemistry. So labels may not tell you what is in a product.

Two species and changing taxonomy. Notopterygium incisum and N. franchetii differ in DNA and chemistry. GBIF now treats them as synonyms of Hansenia weberbaueriana and H. forbesii, so labels may use different names. 15 5 6

Wild vs cultivated. A 2025 metabolomics study found 195 metabolites and differences in chemistry between wild and cultivated rhizome and between growing regions. 11

Endangered wild plants. The 2025 DNA paper calls both species endangered medicinal species (Category III protected plants in China). Buying wild-harvested root can add to that pressure. Not checked against an official list. 15

Heavy metals, pesticides, mix-ups with look-alike Apiaceae roots. No contamination test of retail qiang huo products was found in the sources read.

BodyActionDate
When to get medical help
  • Trouble breathing, swelling of the face or throat, or hives after taking it
  • Blistering, burning or a severe rash on sun-exposed skin
  • Unusual bruising, nosebleeds, blood in vomit or black stools, especially with blood thinners
  • Yellow skin or eyes, dark urine, or very little urine
  • Severe belly pain or repeated vomiting

Frequently asked questions

What is qiang huo?

The dried rhizome and root of Notopterygium incisum or N. franchetii, used in Chinese medicine for aching joints, colds with chills and headache.

1 5

Does qiang huo help arthritis?

Only a formula that includes it has been tested. One 24-week trial in 90 people found a response similar to methotrexate, but the formula was not itemised and the numbers in the abstract do not add up cleanly. We rate it very low certainty.

3

Does it help colds or headache?

This is a traditional use only. We found no human trial.

1

Is qiang huo safe?

We found no human safety study. Lab work suggests it can affect how some medicines are cleared and may affect clotting. It is not a casual herb to combine with prescriptions.

1 4 2

Can it make skin sensitive to the sun?

It contains furanocoumarins, which cause sun sensitivity in some other plants such as parsnip. No study tested this for qiang huo, so treat it as a precaution.

8 10

Does it interact with medicines?

Possibly. In a test tube notopterol blocked CYP2D6, and it blocked thrombin. Rat data were mixed. No human study exists. Tell a doctor or pharmacist about every medicine you take.

4 9 2

Is it safe in pregnancy or breastfeeding?

No safety data were found, so avoid it.

1

Can it hurt the liver?

No human case of liver injury was found, and no LiverTox entry was confirmed. Absence of reports is not proof of safety. If you have liver disease, ask a doctor first.

1 4

Is it the same as du huo (Angelica pubescens)?

No. They are different roots from the same plant family that are often used together in joint formulas. See our Angelica pubescens page.

1

Why do the Latin names differ?

Researchers use Notopterygium, but the GBIF database lists these species as synonyms of Hansenia weberbaueriana and Hansenia forbesii.

5 6

Is the plant endangered?

A 2025 DNA paper calls both species endangered medicinal species protected in China. We did not check an official list. Ask sellers about cultivated sourcing.

15

Should I talk to a professional before using it?

Yes. Speak to a doctor or pharmacist first, including about amounts, especially if you take other medicines, are pregnant, or have liver or bleeding problems.
