Chitrak

Plumbago zeylanica · also called Chitraka, Ceylon leadwort, white leadwort

Chitrak is the root of Plumbago zeylanica, used in Ayurveda for digestion, piles and joint pain. We found no human trials, so none of these uses is proven. Its main chemical, plumbagin, irritates skin, is reported to blister it, and is toxic in animal studies. Do not use it in pregnancy, and talk to a doctor before any use.

About Chitrak

Chitrak is the root of Plumbago zeylanica, an Ayurvedic digestive and joint herb. We found no human trial of it for any use, so benefit is unproven. Its main compound, plumbagin, is a reactive chemical that irritates skin, is reported to blister it, and is toxic to the liver and kidney in rat studies. Traditional use includes ending pregnancy, and a review mentions possible bleeding effects. Avoid it in pregnancy, breastfeeding and childhood, and keep it off skin. Ask a doctor or pharmacist about amounts.

What it is

Chitrak (chitraka) is the root of Plumbago zeylanica, called Ceylon leadwort or white leadwort. It belongs to the leadwort family, Plumbaginaceae.

Two close relatives, Plumbago indica and Plumbago auriculata, are different plants. A DNA study found P. zeylanica in commercial samples sold as P. indica, so mix-ups happen.

14 12

What makes it distinctive

The root contains plumbagin, a reactive compound that gives it both its traditional effects and its harms. The raw root is described as harsh, so Ayurveda purifies it with lime water first. In one study this purification did not remove plumbagin: measured levels rose from 0.29% to 0.98%.

So purified does not mean mild.

18 2

Historical and current uses

Ayurveda uses Chitrak for weak digestion, piles and loose stools, and for rheumatic pain. Ayurvedic fertility texts also list it among plants claimed to end pregnancy. In Ethiopia it has been used on skin diseases.

These are traditional uses. They show it is used, not that it works.

17 1 9

What the research shows

No human trial was found. Rat studies report reduced arthritis signs from a processed-root extract and less weight gain from a three-herb mix. Lab studies show plumbagin can kill cancer cells and resistant bacteria, but it dissolves poorly, is absorbed slowly and has a narrow safety margin, so it has not become a medicine.

The honest picture: a long tradition, interesting lab leads and real toxicity signals, with no human proof of benefit.

Traditional uses history, not proof

  • Ayurveda: root used for weak digestion, piles and loose stools
  • Rheumatic pain and arthritis
  • Traditionally used to end pregnancy, which is a warning, not a recommended use
  • Traditionally purified with lime water before medicinal use because the raw root is described as harsh

Studied for research

  • Digestion and appetite: insufficient evidence (tradition only)
  • Arthritis: insufficient evidence (one rat study)
  • Weight (in a three-herb mix): insufficient evidence (rats)
  • Cancer and bacteria: lab studies of plumbagin only

Main compounds

  • Plumbagin, a reactive naphthoquinone found in the root

Common forms

  • Root powder
  • Purified (processed) root
  • Root extract
  • Mixed Ayurvedic formulas
  • Skin paste or oil (irritating; see safety)

Absorption, metabolism and elimination

Absorption
In rats a single oral dose of plumbagin was absorbed slowly (median time to peak 9.63 h). Reviews say oral bioavailability is low because of poor solubility, metabolic instability and efflux.
Distribution
Not described in the abstracts read.
Metabolism
Reviews cite metabolic instability. Plumbagin raised blood levels of tazemetostat in rats, suggesting it can slow some drug metabolism (animal).
Elimination
Median elimination half-life 5.0 h in rats after a single oral dose.
Bioavailability
Low (reviews); no human data.

Isolated compounds versus whole extracts

Different extracts of the same root differed about ten-fold in rat toxicity, tracking plumbagin content. Traditional purification raised plumbagin content in one study. Results for pure plumbagin cannot be assumed for powdered root, and the reverse.

Studies, doses and limits

What the trials found

No human trial of Chitrak or plumbagin for digestion, appetite or piles was found.

Results

Evidence is traditional use only.

Effect sizes as reported

None

Why this rating

Tradition only. No trial of any kind was found for these uses.

Form and dose studied

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

Who was studied

Not studied in people.

Limits

Everything rests on a 2023 review we only read in summary. No trial exists.

Why researchers looked

It is a classic Ayurvedic digestive root, so this is the main reason people look for it.

Traditional use

Ayurvedic texts describe it for dyspepsia, piles and diarrhoea (via a 2023 review, summary-only). The raw root is described as harsh and is traditionally processed before use.

Proposed mechanism Pharmacological theory

No mechanism has been shown for digestion. Reviews describe plumbagin as a reactive compound that affects many cell processes, which may also explain irritation.

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

The same root that is used traditionally is irritating to skin and toxic in animals. See the safety tab.

Arthritis and rheumatic pain

Not enough evidence

Chitrak is used in Ayurveda for rheumatic pain and joint inflammation. A 2025 rat study found a processed-root extract reduced arthritis signs. No human trial exists.

3 studiesA methanolic extract of processed root was tested in rats. Not applic…

Studies, doses and limits

What the trials found

No human trial found. One rat study with a methanolic extract of processed root.

Results

In rats with induced arthritis, treatment reduced paw swelling and joint diameter, improved walking and weight-bearing, lowered inflammatory markers, and reduced joint tissue damage.

Effect sizes as reported

No numbers in the abstract

Why this rating

Animal evidence only. Findings in rats cannot be assumed for people, and the root is toxic in other rat studies.

Form and dose studied

A methanolic extract of processed root was tested in rats. Not applicable to home preparations.

Who was studied

Rats with induced arthritis.

Limits

Single animal study; doses not given in the abstract; authors say long-term safety must be studied first.

Why researchers looked

Ayurveda advises processed Chitrak root for inflammatory and rheumatic conditions, and researchers wanted to test that.

Traditional use

Used for rheumatic pain and arthritis in Ayurveda; the 2025 review of plumbagin lists arthritis among traditional uses.

Proposed mechanism Preliminary mechanism

In the rat study the extract lowered inflammatory signals (TNF-alpha, IL-6, CRP, COX-2) and oxidative stress markers. The authors say the exact molecules and mechanisms are still unclear.

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

Plumbagin damaged liver and kidney in other rat studies, so benefit and harm cannot be separated from this study.

Weight and metabolism (as part of a mix)

Not enough evidence

A 2026 rat study of a three-herb Ayurvedic mix that includes Chitrak root reduced weight gain on a high-fat diet. The effect cannot be credited to Chitrak, and no people were studied.

Studies, doses and limits

What the trials found

No human trial found.

Results

Rats on a high-fat diet given the mix gained less weight and had better lipid, inflammation and fat-cell measures than untreated rats.

Effect sizes as reported

No numbers in the abstract

Why this rating

Combination product in animals only; effect cannot be assigned to Chitrak.

Form and dose studied

Mix extract at 50, 100 and 200 mg/kg for 48 days in rats; not applicable to people.

Who was studied

Male rats on a high-fat diet.

Limits

Three-herb mix; small groups (6 rats each); abstract-only reading.

Why researchers looked

Ayurveda recommends the mix called Trimad for obesity, and researchers tested it in rats.

Traditional use

Chitraka is one of three herbs in Trimad, an Ayurvedic obesity formula.

Proposed mechanism Preliminary mechanism

In the rat study the mix changed liver fat-handling genes and lowered inflammation and oxidative stress markers. These are animal findings for the whole mix.

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

Chitrak root can harm liver and kidney in animal studies; a weight benefit would not outweigh that on current evidence.

Cancer-cell activity of plumbagin (lab only)

Not enough evidence

In the lab, plumbagin kills or slows cancer cells. That is also why it is toxic. It has not become a medicine, and Chitrak root should never be used to treat cancer.

3 studiesIsolated plumbagin, not the root.

Studies, doses and limits

What the trials found

No clinical trial of plumbagin or Chitrak for cancer was found. Reviews note it has not reached the clinic, partly because it dissolves poorly in water and is toxic.

Results

Lab and animal findings only.

Effect sizes as reported

None

Why this rating

Lab and animal evidence only; the same cell toxicity harms healthy tissue.

Form and dose studied

Isolated plumbagin, not the root.

Who was studied

Cells and animals.

Limits

A 2025 review lists genotoxicity, organ toxicity and oxidative stress as limits.

Why researchers looked

Plumbagin is the most studied compound from the root, and cancer cell work dominates the research.

Traditional use

Not a traditional use of the root as described in our sources.

Proposed mechanism Laboratory research

Reviews describe plumbagin as a reactive naphthoquinone that stresses and kills cells, including cancer cells, in lab work.

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

Cell toxicity and genetic-material damage are reported for plumbagin. See the safety tab.

5 11 10

Antibacterial activity of plumbagin (test tube only)

Not enough evidence

A 2026 lab study found plumbagin slowed and killed a drug-resistant hospital bacterium and weakened its biofilm. Nothing has been tested in people.

2 studiesIsolated plumbagin, not the root.

Studies, doses and limits

What the trials found

No animal or human infection study of plumbagin was found in our searches.

Results

Bacterial growth, killing and biofilm were reduced at low concentrations in the lab.

Effect sizes as reported

No numbers in the abstract

Why this rating

Test-tube evidence only.

Form and dose studied

Isolated plumbagin, not the root.

Who was studied

Carbapenem-resistant Acinetobacter baumannii in the lab.

Limits

Single in-vitro study.

Why researchers looked

Researchers look for new ways to attack resistant bacteria.

Traditional use

Not a traditional use as described in our sources.

Proposed mechanism Laboratory research

Plumbagin lowered activity of a resistance gene (blaOXA-23) and biofilm genes in the bacteria.

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

Plumbagin is toxic to human cells in lab work, so it cannot be assumed safe as an antibacterial.

13 11

Effects on fertility (animal findings; a warning, not a benefit)

Not enough evidence

The root is traditionally used to end pregnancy. Animal studies report abortion-like effects, birth defects in mice and reduced sperm. This is a safety warning, not a health benefit.

2 studiesNot applicable.

Studies, doses and limits

What the trials found

No human study was found. Animal findings reported in a 2021 review: anti-implantation and abortion-like effects, birth defects in mice, sperm-reducing and anti-androgen effects. The original animal studies were not opened.

Results

Animal and traditional-use data only.

Effect sizes as reported

None

Why this rating

Animal and traditional data only; direction of the findings is a clear warning.

Form and dose studied

Not applicable.

Who was studied

Rodents.

Limits

Specific numbers were not read from the original studies.

Why researchers looked

Ayurvedic texts list Chitraka among plants claimed to have contraceptive and abortifacient properties, so researchers tested it in animals.

Traditional use

Traditional abortifacient use (per a 2021 review).

Proposed mechanism Pharmacological theory

Not established. Plumbagin is a reactive compound that is toxic to cells.

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

Avoid in pregnancy and when trying to conceive. See the safety tab.

The evidence

The research centre for Chitrak. 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 Chitrak. Most sources were abstracts only. Some details were carried over from an earlier summary and not re-opened; they are marked. No study is cited that we could not verify.

What we do not know yet

  • No human trial or case report on Chitrak was found.
  • Only abstracts were read; the pregnancy, blistering and vitamin K statements come from reviews whose full text was not re-opened.
  • No human pharmacokinetic or interaction data.
  • NCCIH has no page; LiverTox was blocked; EMA/HMPC, WHO and LactMed were not searched in depth.
  • Native range and plant description were not verified.

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
  • Plumbagin is toxic: the root is not a gentle herb. The main compound in Chitrak root, plumbagin, is called poisonous in a 2025 review, with cell toxicity, organ toxicity, oxidative stress and genetic-material damage. A 2022 review says it has a narrow margin between a useful and a harmful amount, and that data are not enough to prove it is unsafe for people. We found no human trial. Do not treat Chitrak as a casual supplement. Animal research 11 10
  • Irritates skin and is reported to blister. A root extract was a moderate skin irritant in rabbits. Reviews and traditional texts describe the raw root as blistering (vesicant). Keep the root and extracts off skin, eyes and mouth. The sources we read did not directly test mouth or gut lining, but a reactive compound like plumbagin can be expected to irritate them (theory). Animal research 9 11
  • Avoid in pregnancy and when trying to conceive. The root is traditionally used to end pregnancy. A 2021 review reports animal findings of anti-implantation and abortion-like effects, birth defects in mice, and reduced sperm. No human data exist. Do not use it if you are or might be pregnant. Traditional use 1 11
  • Liver, kidney and possible bleeding concerns. In rats, liver and kidney were the main organs harmed by root extracts. A review also says plumbagin may interfere with vitamin K and clotting and cause bleeding with long-term use (summary-only, lab and animal basis). Anyone on blood thinners, or with liver, kidney or bleeding problems, should avoid it. Animal research 6 11

Liver

No human case report of liver injury from Chitrak was found, and no LiverTox entry could be confirmed (the page was blocked). In rats, root extracts raised serum AST and caused liver and kidney changes, so the liver is a plausible target. 6 15

How often. Unknown in people.

Monitoring. No agency advice was found. Do not use if you have liver disease. Stop and seek care for yellow skin or eyes, dark urine or severe tiredness.

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

Overdose, product quality and regulators

Summary. Root extracts and plumbagin are toxic in animal studies, and the amount that is harmful varies a lot between extract types.

Animal. Root extracts in female rats: LD50 about 93 mg/kg for a petroleum ether extract versus about 928 mg/kg for acetone and hydroalcoholic extracts, with liver and kidney changes in repeated dosing. Pure plumbagin was called low in toxicity in another rat study (maximum tolerated 150 mg/kg once, 25 mg/kg daily for 28 days), so reports are mixed.

Human doses studied. No human study found, so no human toxic amount is known.

High dose or long term signals. Raised AST, urea and creatinine, organ weight changes, lower red and white cell measures in rats; a review lists possible bleeding with long-term use (summary-only).

Overdose response. Not described in the sources read. Seek emergency help for any serious reaction.

Genotoxicity. A 2025 review lists genotoxicity. A 2026 preprint (not peer reviewed, summary-only) reports it for extracts in plant and yeast models.

Toxic plant parts. The root is the part used and the richest in plumbagin. Leaves and stem also contain plumbagin according to a review abstract.

Species mix-ups and processing change what a product contains.

Look-alike species. A Thai DNA study found P. zeylanica in commercial samples sold as P. indica root, pointing to adulteration between closely related Plumbago species. 12

Traditional purification. Lime-water purification of Chitraka root did not remove plumbagin: measured plumbagin rose from 0.29% to 0.98% in one set of five batches. So 'purified' does not mean plumbagin-free. 2

Heavy metals, pesticides, adulterants. Not studied in the sources we read.

BodyActionDate
When to get medical help
  • Blisters, burns or a severe rash on skin that touched the root or an extract
  • Pain or swelling in the mouth or throat, or repeated vomiting and severe belly pain after swallowing it
  • Vaginal bleeding or cramping in pregnancy
  • Unusual bruising, nosebleeds, blood in vomit, black stools or other bleeding
  • Yellow skin or eyes, dark urine, or very little urine

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.

Frequently asked questions

What is Chitrak?

The root of Plumbago zeylanica (Ceylon leadwort), used in Ayurveda for digestion, piles and joint pain.

14 17

Does Chitrak help digestion?

It is a classic Ayurvedic digestive root, but we found no human trial. The evidence is tradition only.

17

Is Chitrak safe?

Not as a casual herb. Its main compound, plumbagin, is called poisonous in a recent review and harmed the liver and kidney in rats. We found no human safety data.

11 6

Can Chitrak burn or blister skin?

A root extract was a moderate skin irritant in rabbits, and reviews report that the raw root can blister. Keep it off skin, eyes and mouth.

9 11

Is Chitrak safe in pregnancy?

No. It is traditionally used to end pregnancy, and animal studies report abortion-like effects and birth defects in mice. Avoid it if you are or might be pregnant.

1 11

Does Chitrak affect bleeding or blood thinners?

A review says plumbagin may interfere with vitamin K and cause bleeding. This comes from lab and animal work, not people. Avoid it with blood thinners and ask a pharmacist.

11

Does purification make Chitrak safe?

Not necessarily. In one study lime-water purification raised the measured plumbagin content rather than removing it.

2

Does Chitrak help arthritis?

A 2025 rat study found a processed-root extract reduced arthritis signs. No human trial exists.

3

Can Chitrak help with weight loss?

A three-herb mix containing it reduced weight gain in rats. That cannot be credited to Chitrak, and nothing is proven in people.

4

Does Chitrak treat cancer?

No. Plumbagin kills cancer cells in the lab, but it is also toxic and has not become a medicine. Never use Chitrak instead of cancer treatment.

5 10

Is Chitrak the same as Plumbago indica?

No. They are closely related but different plants, and a DNA study found the two mixed up in commercial roots.

12

Should I talk to a professional before using it?

Yes. Because of the toxicity, speak to a doctor or pharmacist first, including about amounts. Many people are better off avoiding it.
