About Anemarrhena

Anemarrhena asphodeloides is an East Asian plant whose rhizome, zhi mu, is a cooling herb in Chinese medicine. Research is mainly in mice and cells. No human trial of the herb alone was found.

What it is

Zhi mu is the dried rhizome of Anemarrhena asphodeloides. It has been used in China, Japan and Korea for a very long time, per a 2014 review.

It contains steroidal saponins such as timosaponin AIII and BII, and xanthones such as mangiferin. A 2023 review counts 269 compounds.

15 10 4

How it is used in tradition

Reviews list fever, night sweats, dry cough, dry mouth and tongue, coughing blood and joint pain.

It is often one herb in a formula. It is commonly said to be paired with phellodendron and rehmannia in classic formulas. We have not checked this against a primary text.

10

What research shows

Diabetic mice had lower blood sugar after a water extract, and salt-baked rhizome did better than raw in a 2021 study. Rats given saponins had better insulin signals. A meta-analysis of 19 animal studies found the same for pure mangiferin.

In people: a 21-woman skin study with a purified compound and a review of 13 trials of a mixed arthritis formula. Neither tests the herb alone.

Lab studies of cancer, memory and clotting use purified compounds and say nothing yet about people.

Absorption, metabolism and elimination

Absorption
Timosaponin AIII is poorly absorbed by mouth according to the existing summary of the 2020 review (not re-read here). In mice, a 50 mg/kg dose peaked in blood 4 to 6 hours later.
Distribution
Not found.
Metabolism

Isolated compounds versus whole extracts

Most research uses purified timosaponin AIII or mangiferin, or saponin fractions. Ethanol extract beat the water decoction, and salt-baked beat raw, in diabetic mice. Results from pure compounds cannot be applied to a whole-herb product.

Nutritional composition

Zhi mu is a medicinal herb, not a food or a nutrient source.

Benefits, one by one

Each card is a research question, not a promise. Tap a goal to filter. Open a card to see the studies, doses and limits.

Blood sugar and diabetes

Not enough evidence

Zhi mu is a classic Chinese herb for diabetes-type thirst. Diabetic mice and rats did better on its extracts. No trial in people was found, so we do not know if it helps a person.

4 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

None found. We found no randomised trial or other human study of zhi mu by mouth for blood sugar.

Results

Mice: one dose of the water extract lowered blood glucose from 570 to 401 mg/dl at 7 hours. A 2021 study in db/db mice found salt-baked rhizome beat raw rhizome and ethanol extract beat the water decoction. A meta-analysis of 19 animal studies of pure mangiferin (one compound in zhi mu) found lower glucose in diabetic animals.

Effect sizes as reported

Mouse study: 570 +/- 29 to 401 +/- 59 mg/dl (p<0.05). Mangiferin animal meta-analysis: glucose SMD -1.27 (95% CI -1.71 to -0.82). No human numbers.

Why this rating

Animal and lab work only. Pure compounds and extracts differ from a store product. No human evidence.

Form and dose studied

Not given here and not advised.

Who was studied

Diabetic mice and rats. Nothing in people, children or pregnancy.

Limits

The 2021 abstract gives no numbers. Mangiferin is also in other plants, so the mangiferin meta-analysis does not prove anything about zhi mu.

Why researchers looked

In Chinese medicine zhi mu is used for dry mouth, thirst and heat, which overlap with what is now called diabetes. Researchers tested it in diabetic animals.

Traditional use

Named in classical formulas for thirst and heat patterns (textbook knowledge, not checked against a primary text here). A 2023 review lists dry mouth and tongue among its traditional uses.

Proposed mechanism Animal and in vitro

Mangiferin and its glucoside were named as active parts in a 2001 mouse study, which suggested less insulin resistance. A rat study with purified saponins found more activity in the insulin-signalling proteins IRS-1, PI3K and AKT and less sugar-making activity in the liver.

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

Anyone using diabetes medicine should not change it without their doctor. A herb that lowers sugar could add to the medicine's effect and cause low blood sugar. This is a theory, not a documented interaction.

Memory and thinking

Not enough evidence

One purified zhi mu compound improved memory in mice whose memory was blocked by a drug. This has not been tested in people.

1 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

None found.

Results

Timosaponin AIII reversed the memory deficits caused by scopolamine in two mouse tests.

Effect sizes as reported

No human numbers. Enzyme block IC50 35.4 micromolar (cell test).

Why this rating

One purified compound in drug-impaired mice.

Form and dose studied

Not given here and not advised.

Who was studied

Mice.

Limits

A chemical memory-loss model is not the same as dementia. Absorption by mouth is poor according to the existing summary of a 2020 review.

Why researchers looked

Timosaponin AIII blocks an enzyme (acetylcholinesterase) that is also the target of some Alzheimer's medicines.

Traditional use

Not a classic zhi mu use in the sources read.

Proposed mechanism Animal and in vitro

Timosaponin AIII raised acetylcholine in the mouse hippocampus, blocked acetylcholinesterase (IC50 35.4 micromolar) and lowered inflammation signals.

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

Anyone taking dementia medicines should ask a doctor or pharmacist before adding any herb.

Fever, dry cough and thirst (traditional use)

Not enough evidence

In Chinese medicine zhi mu cools heat and moistens dryness. This is a tradition. No trial of these uses was found.

2 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

None found for these uses.

Results

Reviews describe the tradition and lab findings only.

Effect sizes as reported

None.

Why this rating

Tradition only; no human study read.

Form and dose studied

Not given here and not advised.

Who was studied

Not studied.

Limits

Fever and cough can be serious. A traditional use is not a trial result.

Why researchers looked

Traditional use for tidal fever, night sweats, dry cough, dry mouth and tongue and coughing blood is listed in two reviews.

Traditional use

Used for thousands of years in China, Japan and Korea per the 2014 review. Often one herb in a formula such as Baihu decoction or Zhi Bai Di Huang Wan (formula details not checked against a primary text).

Proposed mechanism Pharmacological theory

Not established. Lab studies show anti-inflammatory and other activity of single compounds.

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

A fever that lasts, breathing trouble or coughing blood needs a doctor, not a herb.

10 15

Rheumatoid arthritis (as part of a formula)

Very low certainty

A formula that always contains zhi mu, cassia twig and peony looked helpful in a review of 13 trials, but zhi mu's own part cannot be told apart.

1 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

A 2017 meta-analysis pooled 13 randomised trials of the formula (with or without standard drugs) against standard drugs or placebo.

Results

The authors say it was three to six times more effective than standard drugs for some symptoms and that only two studies reported side effects in the formula group. They call for larger, longer trials.

Effect sizes as reported

Not given in the abstract beyond the authors' summary.

Why this rating

Mixed formula, varied recipes, small trials of uncertain quality, and a first author employed by a supplement maker. The authors did not give a formal GRADE in the abstract.

Form and dose studied

Not given here and not advised.

Who was studied

Adults with rheumatoid arthritis.

Limits

Cannot say whether zhi mu did anything. Rheumatoid arthritis needs medical care.

Why researchers looked

Joint pain (arthralgia) is a traditional use of zhi mu, and the Gui Zhi-Shao Yao-Zhi Mu decoction is used for rheumatoid arthritis.

Traditional use

Joint pain is on the traditional use list in the 2023 review.

Proposed mechanism Pharmacological theory

Not established for zhi mu alone.

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

Do not replace arthritis medicine with a herb.

2

Skin wrinkles (cream with one compound)

Very low certainty

A small 12-week study of 21 women found fewer wrinkle signs with a cream containing 0.25% timosaponin A-III. It is one purified compound on the skin, not the herb by mouth.

1 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

One small human study, 21 women aged 43 to 55.

Results

Wrinkle measures fell significantly after 12 weeks (P<0.05); no skin toxicity was seen.

Effect sizes as reported

P<0.05; no numbers in the abstract.

Why this rating

Very small study, unclear control, company-linked authors.

Form and dose studied

Not given here and not advised.

Who was studied

Women aged 43 to 55.

Limits

Only 21 women. A purified compound in a skin product is not the same as eating the herb.

Why researchers looked

In skin cells exposed to UVB light, the compound lowered an enzyme (MMP-1) that breaks down skin structure.

Traditional use

A review lists anti-skin-ageing among zhi mu's lab activities.

Proposed mechanism In vitro

Lowered MMP-1 and inflammation signals in UVB-exposed skin cells.

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

No skin toxicity was reported in this study. Stop any skin product that causes a rash.

6

Platelets and clotting (lab)

Not enough evidence

A zhi mu compound slowed platelet clumping and clotting in animals. This is a lab finding, not a proven effect in people, but it matters for blood thinners.

2 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

None found.

Results

aPTT rose by 9.29, 16.86 and 25.50% at three animal doses; clot weight fell by 13.6, 19.8 and 24.7%. No effect in a rabbit shunt model.

Effect sizes as reported

As above (animals, injected).

Why this rating

Animal and test-tube work with an injected purified compound.

Form and dose studied

Not given here and not advised.

Who was studied

Rats, rabbits, platelets in vitro.

Limits

Says nothing about eating the herb.

Why researchers looked

Reviews list antiplatelet activity of zhi mu compounds.

Traditional use

Not a classic use in the sources read.

Proposed mechanism Animal and in vitro

Timosaponin B-II blocked ADP-triggered platelet clumping and lengthened aPTT in animals; prothrombin time was unchanged.

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

Theoretical extra bleeding risk with blood thinners or before surgery. Not a documented human interaction.

11 9

Cancer cell and tumour models (lab)

Not enough evidence

Timosaponin AIII kills many cancer cell lines in dishes and slows tumours in animals. There is no human evidence, and it is not a cancer treatment.

2 studiesNot given here and not advised.

Studies, doses and limits

What the trials found

None found.

Results

Two reviews (2020, 2024) describe lab and animal findings only.

Effect sizes as reported

None.

Why this rating

Cells and animals only; purified compound.

Form and dose studied

Not given here and not advised.

Who was studied

Cell lines and animals.

Limits

Dish results rarely carry over to people. Poor absorption by mouth is reported for the compound.

Why researchers looked

The compound is the most researched part of zhi mu in cancer labs.

Traditional use

Not a traditional zhi mu use.

Proposed mechanism In vitro and animal

Reviews describe effects on cell death, spread and autophagy in many cancer cell lines.

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

Anyone in cancer treatment should ask the oncology team first; a mouse study found an interaction with tamoxifen (see Safety).

The evidence

The research centre for Anemarrhena. 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, GBIF and PubChem and read abstracts. Not verified: EMA/HMPC, NCCIH (no page found), LiverTox, LactMed, Chinese Pharmacopoeia, and the traditional loose-stool caution. Ratings are the compiler's own reading, not formal grades.

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 3
  • Almost no human safety data. We found no clinical trial or case report of oral zhi mu safety. The 2023 review says quality and toxicity must be evaluated to confirm safe use in people. Absence of reports is not proof of safety. Authoritative guidance 10 15
  • Liver: a question for the purified compound. A 2020 review names liver toxicity as the main concern for isolated timosaponin AIII in lab and animal work. Human liver safety of the whole herb is unknown. Animal research 9
  • Possible medicine interactions (lab and animal only). Blood-sugar medicines (theory), tamoxifen (mouse study), medicines moved by P-glycoprotein (cell study), medicines broken down by CYP enzymes (mouse and cell studies) and blood thinners (animal study). None has been shown in people. Animal research 8 1 5 11

Controlled trial 6
Liver

No human liver-injury case of zhi mu was found. A 2020 review calls liver toxicity of purified timosaponin AIII the main safety concern in cell and animal work. An NIH LiverTox page for zhi mu was not found, so no official liver rating can be given. 9

How often. Unknown.

Monitoring. No official advice. Anyone with liver disease, or taking medicines that affect the liver, should ask a doctor before using it.

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

Medicines and supplements 5
WithWhy it mattersImportanceEvidenceWhat to do
Diabetes medicines (insulin, metformin, sulfonylureas and others)
drug
Extracts and mangiferin lowered blood glucose in diabetic animals.Unknown. If an effect existed in people it could add to the medicine and cause low blood sugar (hypoglycaemia).Theoretical Not enough evidence 12 16Do not change diabetes treatment. Ask a doctor or pharmacist, and check blood sugar as advised.

Medicines moved by P-glycoprotein (for example some heart and cancer medicines)
drug
In lab cells, timosaponin AIII, BII, mangiferin and baohuoside I were P-gp substrates and several compounds blocked P-gp.Unknown in people.Laboratory research Not enough evidence 1Ask a pharmacist about any medicine with a narrow safety margin.
Medicines broken down by CYP enzymes (CYP3A4, CYP2B6)
drug
Timosaponin AIII raised CYP2B10, CYP3A11 and MDR1 in mice and CYP2B6, CYP3A4 and MDR1 in human liver cells through the CAR switch. Other work above found CYP450 inhibition by the formula and mangiferin.Unknown. The lab results point both ways (more breakdown from the saponin, less from mangiferin), so the net effect in people cannot be predicted.Animal research Not enough evidence 5 8Ask a pharmacist before combining with any prescribed medicine.

Overdose, product quality and regulators

Summary. No toxicity study of the whole herb in people was found. The existing lab summary of timosaponin AIII points to the liver; details were not re-checked here.

Animal. The 2020 review names liver toxicity of timosaponin AIII as the main concern and says toxicity needs more study in diverse animal models.

Human doses studied. None for oral use.

High dose or long term signals. Unknown.

Overdose response. Unknown. Seek medical help for severe vomiting, diarrhoea, yellow skin or eyes, or bleeding.

Genotoxicity. Not studied in the sources read.

Toxic plant parts. The rhizome is the part used. No poisonous plant part was identified in the sources read.

No product testing was found.

Plant identity and quality. The 2023 review says quality evaluation is essential and discusses quality control. Salt-baking and extraction change the compound content (2021 mouse study), so products can differ a lot. 10 17

Heavy metals, pesticides, adulteration. Not found in the sources read.

BodyActionDate
When to get medical help
  • Yellow skin or eyes, dark urine or severe stomach pain
  • Black stools, vomiting blood, or bleeding that will not stop
  • Shakes, sweating, confusion or fainting (low blood sugar) if you take diabetes medicine
  • Severe or lasting diarrhoea
  • Rash, swelling of the face or trouble breathing

Stop the supplement and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.

Frequently asked questions

What is zhi mu (anemarrhena)?

Zhi mu is the dried underground stem (rhizome) of Anemarrhena asphodeloides, an East Asian plant. In Chinese medicine it is a cooling herb for fever, dry cough, thirst and night sweats.

10 4

Does anemarrhena lower blood sugar?

In diabetic mice and rats, extracts and compounds from it did. We found no study in people, so we do not know if it works for a person.

12 17 3

Is it safe with diabetes medicine?

Not known. Because it lowered blood sugar in animals, it could in theory add to diabetes medicine and cause low blood sugar. Do not change treatment; ask a doctor or pharmacist.

12 16

Does it help with cough or fever?

It is a traditional use only. No trial of these uses was found. A fever that lasts or coughing blood needs a doctor.

10 15

What is in it?

Steroidal saponins such as timosaponin AIII and BII, and xanthones such as mangiferin. A 2023 review counts 269 compounds.

10 13

Is there human evidence for any use?

Very little. One small 12-week skin study (21 women) used a cream with a purified compound, and a review of 13 trials looked at a mixed arthritis formula that contains zhi mu. Neither tests the herb alone by mouth.

6 2

Is it good for the liver or bad for it?

Unknown. A review names liver toxicity as the main concern for purified timosaponin AIII in lab and animal work. No human liver case was found.

9

Can it interact with medicines?

Possibly, but only lab and animal findings exist: tamoxifen (mouse study), drugs moved by P-glycoprotein (cell study), drugs broken down by CYP enzymes (mouse and cell studies) and blood thinners (animal study). Ask a pharmacist.

8 1 5 11

Is it safe in pregnancy or breastfeeding?

No safety data were found. Avoid it unless a doctor says otherwise.

10

Can it upset the stomach?

Traditional teaching cautions people with loose stools or weak digestion. We could not confirm this in a source, and no human report of stomach side effects was found.

Does salt-baking make a difference?

In diabetic mice, salt-baked rhizome worked better than raw, and ethanol extract better than a water decoction. It is not known whether this applies to people.

17

Where can I ask about amounts?

We do not give amounts. Ask a doctor, pharmacist or trained practitioner of Chinese medicine, especially if you take medicines.
