Chirata
Swertia chirayita · also called Chirata, chiretta, chirayita, chiraito, Indian gentian, bitter stick
Chirata is a very bitter Himalayan plant used in Ayurveda for fever, digestion, jaundice and diabetes. We found no trial in people, only traditional use and studies in animals and cells, so every use is rated insufficient. The key cautions are low blood sugar if you take diabetes medicines, no safety data in pregnancy, and wild plants that are endangered and often substituted.

About Chirata
Chirata is a bitter Himalayan herb long used in Ayurveda for fever and digestion. Research is mostly in animals and cells, so we cannot say if it works in people. Take care with diabetes medicines, in pregnancy, and when buying it, as the wild plant is endangered and can be substituted.
What it is
Chirata is Swertia chirayita, a plant of the gentian family that grows in the temperate Himalayas. The whole plant, including the roots, is dried and used.
Its taste is very bitter, thanks to compounds such as amarogentin and swertiamarin. It is related to gentian and centaury, two European bitter herbs.
What the evidence shows
We found no controlled trial of chirata in people. What exists is traditional use, reviews, animal studies and test-tube work.
Pure amarogentin lowered blood sugar in diabetic rats, and a chirata extract protected mouse livers from paracetamol injury. Reviews of the plant and of the wider gentian family agree that clinical trials are still needed.
Quality, adulteration and the endangered wild plant
Wild chirata has declined across the Himalayas, and reviews call it endangered. India has restricted export of wild-harvested chirata since 2004. Cultivation in Nepal now supplies much of the trade.
A lab study showed that other Swertia species and Halenia elliptica can be told apart from chirata by chemical fingerprint, which suggests they may be used as substitutes. Look for the Latin name, the plant part and a cultivated source.

Absorption, metabolism and elimination
- Absorption
- No human data. Not covered in abstracts we read.
- Distribution
- Not covered.
- Metabolism
- Not covered.
- Elimination
- Not covered.
- Bioavailability
- Not studied in people for chirata. Our earlier summary says swertiamarin is poorly absorbed by mouth in rats; that source was not re-read.
Isolated compounds versus whole extracts
Most mechanism work uses single compounds (amarogentin, swertiamarin, mangiferin). Results with a pure compound do not tell us how a whole-plant product behaves, and extracts differ from product to product.
Nutritional composition
Chirata is a medicinal bitter herb, not a food or nutrient.

Blood sugar and diabetes (traditional use; animal and lab work only)
Not enough evidenceChirata is used in Ayurveda as a bitter herb for diabetes, and rat studies of chirata extracts and of one of its bitter compounds, amarogentin, show lower blood sugar. We found no trial in people, so we cannot say whether it lowers blood sugar in humans or how safely.
5 studiesNo amount or form is recommended here. Ask a doctor or pharmacist abo…
Studies, doses and limits
What the trials found
No controlled trial in people was found in the reviews or searches. A 2020 review says the compounds have not been well characterised for human use and that safety work is needed. A 2025 review of the whole gentian family says well-designed clinical trials are still needed.
Results
Animals: blood sugar fell in diabetic rats given pure amarogentin. People: no data. Numbers from reviews were not read beyond abstracts.
Effect sizes as reported
None.
Why this rating
Animal and lab findings only, no human trial. Reviews are narrative and cite mixed-quality studies.
Form and dose studied
No amount or form is recommended here. Ask a doctor or pharmacist about amounts.
Who was studied
Adults with diabetes use chirata traditionally; no study in this group.
Limits
Abstracts only. The animal study used a pure compound, not chirata. Gentian-family reviews are not chirata-specific.
Why researchers looked
Diabetes is a common long-term condition, and bitter plants are an old folk remedy for it. Reviews list chirata as one of the plants with blood-sugar-lowering potential.
Traditional use
Ayurvedic and other South Asian traditions use chirata for diabetes, often as part of mixed herbal formulas.
Proposed mechanism Animal research
In rats, the isolated compound amarogentin raised the muscle sugar-transporter GLUT4 and lowered a liver enzyme (PEPCK) that makes sugar. This has not been shown to explain any effect in people.
A proposed mechanism does not show that the effect happens in people.
Do not replace diabetes medicines or monitoring. If you take insulin or tablets for diabetes, chirata could in theory add to the blood-sugar drop (see Safety); this is not confirmed in people.
Liver protection (mouse and cell studies only)
Not enough evidenceIn mice given paracetamol to injure the liver, a chirata extract lowered the liver blood tests and kept the tissue healthier. Compounds from chirata also lowered hepatitis B markers in infected cells in the lab. Nothing has been tested in people, so chirata cannot be called a liver treatment.
4 studiesNo amount or form is recommended here. Ask a doctor or pharmacist abo…
Studies, doses and limits
What the trials found
No human data found. Mouse study (Nagalekshmi 2011): extract at 100-200 mg/kg protected against paracetamol injury, dose-dependently. Cell study (Zhou 2015): several chirata compounds lowered hepatitis B antigen release and viral DNA copying in a liver cell line.
Results
Mice: significantly lower liver enzymes and less tissue damage. Cells: some compounds reduced hepatitis B markers. People: none.
Effect sizes as reported
None.
Why this rating
Animal and cell work only; no human trial of any kind.
Form and dose studied
No amount or form is recommended here. Ask a doctor or pharmacist about amounts.
Who was studied
Laboratory mice and a human liver cell line.
Limits
Abstracts only. The mouse model is a one-off acute injury. The reviews are narrative.
Why researchers looked
Chirata is used in Ayurveda and Tibetan medicine for jaundice and liver complaints, so scientists test it on injured animal livers and virus-infected liver cells.
Traditional use
Traditional use for jaundice and liver disorders in India, Nepal and Tibet.
Proposed mechanism Animal research
Lab work suggests antioxidant effects and lower oxidative damage markers in the liver. Not shown in people.
A proposed mechanism does not show that the effect happens in people.
Protection in a mouse does not mean safety for a person with liver disease. Yellow skin or eyes, dark urine or severe tiredness need medical care. See the Safety tab on the lack of human liver safety data.
Digestion, appetite, fever and worms (traditional use only)
Not enough evidenceChirata is a very bitter plant, and bitter plants have long been used to stir appetite and settle digestion. Traditional systems also use it for fever, vomiting and worms. We found no trial testing any of these uses in people.
2 studiesNo amount or form is recommended here. Ask a doctor or pharmacist abo…
Studies, doses and limits
What the trials found
None found. Two reviews describe the traditional uses; neither reports a human trial of chirata for digestion or fever.
Results
No results in people.
Effect sizes as reported
None.
Why this rating
Traditional use only; reviews do not cite controlled human studies for these uses.
Form and dose studied
No amount or form is recommended here. Ask a doctor or pharmacist about amounts.
Who was studied
Adults in traditional practice
Limits
Abstracts and a partial full text; no trial data.
Why researchers looked
This is what chirata is best known for in practice: a bitter tonic taken before or after meals in traditional systems.
Traditional use
Ayurveda, Unani and Siddha medicine use chirata for fever, vomiting, digestive problems and jaundice, and the plant has been listed in Indian, British and American pharmacopoeias.
Proposed mechanism Pharmacological theory
Bitter taste is thought to prompt digestive juices through taste receptors; this is a general idea about bitter herbs and has not been tested for chirata.
A proposed mechanism does not show that the effect happens in people.
Bitter herbs can irritate the stomach in some people; ask a doctor if you have an ulcer or reflux. Fever that lasts needs medical care.
Inflammation, pain and antioxidant activity (animal and lab only)
Not enough evidenceChirata extracts and compounds reduce inflammation and oxidative stress markers in animals and cells. No human study has tested whether this helps pain or swelling in people.
3 studiesNo amount or form is recommended here. Ask a doctor or pharmacist abo…
Studies, doses and limits
What the trials found
No human data found. Reviews list anti-inflammatory and antioxidant findings from lab and animal studies; a 2025 gentian-family review says the same for the family as a whole.
Results
No human results.
Effect sizes as reported
None.
Why this rating
Animal and cell findings only.
Form and dose studied
No amount or form is recommended here. Ask a doctor or pharmacist about amounts.
Who was studied
Cells and laboratory animals.
Limits
Abstracts only; the family review is not chirata-specific.
Why researchers looked
Reviews of the plant list anti-inflammatory and antioxidant effects as among its main lab findings.
Traditional use
Used traditionally for fever, skin problems and general inflammation in Ayurveda.
Proposed mechanism Animal research
Lab work reports antioxidant activity and effects on inflammation signals. Results are from cells and animals.
A proposed mechanism does not show that the effect happens in people.
Not shown to relieve pain or swelling in people; do not delay care for ongoing pain.
Infections, malaria and antiviral activity (test-tube work only)
Not enough evidenceIn the lab, extracts and compounds from chirata have shown activity against some germs, the malaria parasite and a hepatitis B virus model. No human has been shown to be treated successfully, and malaria needs proper medical treatment.
3 studiesNo amount or form is recommended here. Ask a doctor or pharmacist abo…
Studies, doses and limits
What the trials found
No human trial found. A 2001 lab study tested chirata extracts against malaria parasites in the test tube (its abstract gives no numbers). A 2015 cell study found some compounds lowered hepatitis B markers.
Results
No results in people.
Effect sizes as reported
None.
Why this rating
Test-tube evidence only.
Form and dose studied
No amount or form is recommended here. Ask a doctor or pharmacist about amounts.
Who was studied
Parasites and virus-infected cells in the lab.
Limits
Abstracts only; the malaria abstract does not give results.
Why researchers looked
Chirata has been used in folk medicine for fever and malaria, so it was tested against the malaria parasite and other germs in the lab.
Traditional use
Used in Ayurveda and folk medicine for fevers and malaria-like illnesses.
Proposed mechanism Laboratory research
Not established. Lab tests show activity in cells, which is far from a working treatment.
A proposed mechanism does not show that the effect happens in people.
Malaria and other fevers can be fatal and need medical care and tested medicines. Chirata is not a substitute for them.
Cancer cells in the lab (test-tube work only)
Not enough evidenceReviews list antitumor findings for chirata extracts and compounds in cell tests. No study in people was found, and cell tests are not evidence that an herb treats cancer.
1 studiesNo amount or form is recommended here. Ask a doctor or pharmacist abo…
Studies, doses and limits
What the trials found
None found in people. One review abstract lists antitumor activity among the lab findings.
Results
No human results.
Effect sizes as reported
None.
Why this rating
Lab cell findings only.
Form and dose studied
No amount or form is recommended here. Ask a doctor or pharmacist about amounts.
Who was studied
Cancer cell lines.
Limits
Abstract only.
Why researchers looked
Bitter compounds such as amarogentin are tested for effects on cancer cells in the lab.
Traditional use
Not a traditional use in the sources we read.
Proposed mechanism Laboratory research
Cell-level effects only; not shown in people.
A proposed mechanism does not show that the effect happens in people.
Do not use chirata in place of cancer treatment.

The evidence
The research centre for Chirata. 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 read our existing herb summary, then searched PubMed, read the abstract of each PubMed record cited, and checked names in GBIF and PubChem. Items marked summary-only or not verified were not read further.

Estimated Nepal production of about 711 tonnes in 2013 and about 503 tonnes in 2014, most of it exported to India and Tibet. Declines in wild populations are widely noted across its range. India banned export of wild-harvested chirata, its parts and extracts in 2004 (formulations excepted). Cultivation in eastern Nepal has run for about 25 years and supplies significant quantities, but the price paid to farmers fell from NRs750/kg in April 2013 to NRs250/kg in December 2017, making it less profitable for farmers.

Five chirata ecotypes and five possible substitutes collected in the Indian Himalaya (S. bimaculata, S. chordata, S. ciliata, S. paniculata, Halenia elliptica) | Chirata whole plant samples versus look-alike substitutes whole plant Not given here Not given here |
The chemical fingerprint of the chirata samples matched each other closely (similarity above 0.925) and matched the substitutes poorly (below 0.629), so the method could detect substitution. Methods, limits and fundingOutcomes: Chemical fingerprint (swertiamarin, mangiferin, gentiopicroside, sweroside) to tell chirata from substitutes Limitations: Lab method study of a small set of samples; shows adulterants exist as possible substitutes and can be detected; does not measure how often they occur on the market.

What we do not know yet
- No controlled human trial of chirata for any use.
- No human safety, pregnancy or interaction data.
- Products are not standardised; adulteration is a quality issue.
- Conservation status not checked on the IUCN Red List.
How new research is added
New studies are found by a saved PubMed search and placed in a review queue. A person reads each one before it is added.
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 3
- Almost no human safety data exist for chirata. No controlled trial and no human safety study of chirata was found. Reviews say there is not enough information on the safety of the plant and call for formal toxicity and clinical safety work. Traditional use over centuries and some mouse results showing no obvious toxic effects are reassuring but are not proof of safety, especially for long-term use, pregnancy or people on medicines. Authoritative guidance 7 14 4
- If you take medicines for diabetes, ask before using chirata. Chirata extracts and a pure bitter compound lowered blood sugar in animals. In theory this could add to diabetes medicines (insulin, sulfonylureas and others) and cause low blood sugar with shakiness, sweating, confusion or fainting. No human case or study was found, so this is a theoretical concern based on animal data. Do not stop or change diabetes medicines on your own. Preliminary mechanism 4 12 5
- Wild chirata is endangered, and market herbs can be substituted. Reviews say over-collection and habitat loss have put wild Himalayan chirata at risk, and that supplies are adulterated. A lab study showed look-alike Swertia species and Halenia elliptica can be told apart from chirata by chemical fingerprint, which implies they can be used as substitutes. India restricts export of wild-harvested chirata. Prefer products that name the species and say whether the plant was cultivated. Laboratory 7 3 13
Side effects 1
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Stomach upset (nausea, discomfort) Not documented in a trial. Very bitter herbs commonly upset sensitive stomachs; this is a general expectation, not a measured chirata finding. | Not established | mild Not described | Traditional reference 7 |
Liver
No human case report of liver injury from chirata was found in a short PubMed search, and LiverTox has no chirata entry that we found. This is absence of data, not proof of safety. The 'liver protection' in mice does not tell us how the herb behaves in people with liver disease or on liver-affecting medicines. Herb-labelled products can be adulterated, and any herbal product can occasionally harm the liver. 11 7
How often. No data.
Monitoring. No monitoring advice is established. Seek care for yellow skin or eyes, dark urine, pale stools or severe tiredness.
This is a safety connection. It is not evidence that Chirata supports liver health.
Medicines and supplements 3
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Diabetes medicines (insulin, sulfonylureas, others) drug | Chirata extracts and amarogentin lowered blood glucose in animals; additive blood-sugar lowering is possible. | Unknown. No human interaction case or study found. | Preliminary mechanism Not enough evidence 4 12 | Tell your doctor or pharmacist before using chirata and watch for low blood sugar if you do. |
| Other blood-sugar-lowering herbs (for example bitter melon) herb | Possible additive effect if both lower blood sugar. | Theoretical only. | Pharmacological theory Not enough evidence 5 | Do not stack several blood-sugar herbs without a clinician. |
| Medicines handled by the liver (general) drug | Not studied for chirata. A 2025 gentian-family review is general and not chirata-specific. | Unknown. | Pharmacological theory Not enough evidence 1 | Tell your pharmacist you take it. |
Who should check first 5
| Situation | Advice | Evidence |
|---|---|---|
| Pregnancy and breastfeeding | No safety data were found. Avoid unless a clinician who knows your situation agrees. | Traditional reference 7 |
| Children | No safety data. Do not give to children without medical advice. | Traditional reference 7 |
| Stomach ulcer, gastritis or excess stomach acid | Bitter herbs can stimulate stomach secretions or irritate; no chirata study tested this. Ask a doctor first. | Pharmacological theory |
| Diabetes treated with medicines | Ask before use because of possible low blood sugar (theoretical). | Preliminary mechanism 4 12 |
| Planned surgery | Not studied. Tell your surgeon about any herb because of possible blood-sugar effects. | Pharmacological theory |
Overdose, product quality and regulators
Summary. The 2016 review says chirata is traced through medical history as a non-toxic, safe herb and that extracts did not cause obvious toxic effects in mice (no differences in body weight and temperature), but it also says formal toxicity and mutagenicity tests are still needed.
Animal. Mouse studies cited in the review: no obvious toxicity. Details not read beyond the review.
Human doses studied. No human studies found.
High dose or long term signals. Not studied.
Overdose response. Unknown. Seek care if you feel unwell after taking a lot.
Genotoxicity. Not tested in the sources we read; the review calls for mutagenicity tests.
Toxic plant parts. The whole plant and underground parts are used; no toxic part has been named in the sources we read.
The main concerns are look-alike substitutes and mislabelling driven by high demand and a shrinking wild supply.
Possible substitutes. A lab study compared five chirata ecotypes with five possible substitutes (four other Swertia species and Halenia elliptica) and found the chemical fingerprints clearly different, so substitution can be detected. 13
Adulteration of supplies. A 2016 review says high demand has led to unscrupulous collection and adulteration of supplies. 7
Mislabelling of endangered herbs in markets (general). A DNA study of 22 Indian market herb samples found only two authentic samples (not chirata). Chirata was not named in what we read. 9
| Body | Action | Date |
|---|---|---|
| Government of India (export rule) (India) | Since 2004, export of wild-harvested chirata, its parts and extracts is prohibited, except for formulations. source | 2004 |
When to get medical help
- Shaking, sweating, confusion or fainting after using chirata with diabetes medicines (possible low blood sugar).
- Yellow skin or eyes, dark urine or severe tiredness after a herbal product.
- Fever that lasts more than a day or two, or any fever after travel to a malaria area: seek medical care, do not treat malaria with herbs.
Stop the supplement and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.
General information only, not medical advice. Ask a clinician or pharmacist before use, especially with medicines, in pregnancy or with a health condition. See the Natural Remedy Safety guide.
