Morinda root
Morinda officinalis · also called Ba ji tian, Chinese morinda
Morinda root, called ba ji tian in China, is a tonic root used for bones, mood and sexual vigour. The best study evidence is for purified sugar capsules, which did about as well as antidepressants in seven trials in China, but none used a dummy pill. For bones and menopause the trials mostly tested herbal mixtures. Avoid it in pregnancy, ask first if you have a hormone-sensitive condition, and do not confuse it with noni.

About Morinda root
Morinda root is a Chinese tonic root. Purified sugar capsules matched antidepressants in trials in China, but there was no placebo group. Bone and menopause uses rest on herbal mixtures. Safety data in people are thin. Avoid in pregnancy, and it is not noni.
Safety first
Not noni: Morinda root (Morinda officinalis, also called Gynochthodes officinalis) is a different plant from noni (Morinda citrifolia). The two roots are used interchangeably in Chinese medicine with no experiment supporting that, and chemistry can tell them apart. Noni has its own page and its own liver-injury reports. Check the Latin name on a label.
Pregnancy and breastfeeding: avoid. No safety data were found, and a consumer drug reference advises against it.
Hormone-sensitive conditions: ask your doctor first. No human study measured hormones, but the root sugars changed sex hormones in mice. This is a precaution.
Antidepressants and other mood medicines: the trials compared the capsules against antidepressants, not with them. Do not stop or swap an antidepressant without your prescriber.
Liver: the root contains anthraquinones. We found no human liver-injury report, and animal and cell work was reassuring, but no human liver study exists. See a doctor about yellow skin or eyes or dark urine.
Blood sugar and surgery: a consumer reference warns it might change blood sugar and advises stopping 2 weeks before surgery. This is not confirmed by a clinical source. Quality: one 2026 test found harmful-type bacteria in 40% of 30 batches of five dried Chinese herbs, including Morinda root (not given per herb), so buy from makers that test. Ask a doctor or pharmacist about amounts and your medicines.
What it is
Morinda root is the dried root of a plant of the coffee family (Rubiaceae), used mainly in China. GBIF now lists the accepted name as Gynochthodes officinalis, with Morinda officinalis as a synonym. In China it is called ba ji tian.
Reviews list more than 100 compounds. The main groups are sugars (polysaccharides and oligosaccharides, including inulin-type ones), iridoid glycosides such as monotropein, and anthraquinones.
What the research shows
Mood: a 2021 meta-analysis of 7 trials (1,384 adults with mild to moderate depression, China) found purified oligosaccharide capsules did not differ from antidepressants in effect (risk ratio 0.99) or adverse events (0.84; low-quality evidence). No placebo group. An 8-week trial of 108 adults added probiotics to the capsules and found no change in total depression score.
Bones: a 2026 review found 11 trials, mostly herbal mixtures, reporting benefit in osteoporosis with no evident adverse reactions, and called for trials of the root alone.
Menopause: the root is one of six herbs in Erxian decoction. A 2019 review of 16 studies called the studies low quality.
Sexual function, fatigue, immune and inflammation uses rest on tradition and lab or animal work. Everything labelled lab or animal does not show benefit in people.

Absorption, metabolism and elimination
- Absorption
- After oral use, the review reports wide tissue distribution of root compounds, influenced by sex and processing.
- Distribution
- Monotropein and deacetylasperulosidic acid reach various organs and tissues (animal data).
- Metabolism
- Not found for the whole root in people.
- Elimination
- Not found.
- Bioavailability
- Not found in people.
Isolated compounds versus whole extracts
Depression trials used purified oligosaccharide capsules, not the plain root. Mouse and cell studies used isolated sugars or compounds (nystose, bajijiasu). Toxicity tests used fermented root or a two-herb liquid. Results do not carry over from one form to another.
Nutritional composition
Morinda root is a medicinal herb, not a source of any essential nutrient. Its oligosaccharides are inulin-type sugars, but no source we read tested effects on gut bacteria in people.

Mild to moderate depression (purified oligosaccharide capsules)
Low certaintyIn China, capsules of purified sugars from the root did about as well as standard antidepressants in seven trials. No trial compared them with a dummy pill, so we cannot tell how much of the effect is the root.
2 studiesPurified oligosaccharide capsules were tested, not the dried root or …
Studies, doses and limits
What the trials found
A 2021 meta-analysis of 7 randomised trials (1,384 adults with mild to moderate depression, all in China) found no difference from antidepressants in effect (risk ratio 0.99) or in adverse events (0.84). An 8-week trial of 108 adults added probiotics to the capsules and found no difference in total depression score; both groups took the root sugars, so it does not test the root against placebo.
Results
Effect versus antidepressants: risk ratio 0.99 (95% CI 0.92-1.06). Adverse events: 0.84 (0.65-1.07), rated low quality by the authors. In the 108-person trial, total HAMD-17 change did not differ between groups (p=0.983).
Effect sizes as reported
Non-inferior to antidepressants in the meta-analysis; no placebo comparison anywhere.
Why this rating
Low: head-to-head trials against drugs show similar results, but none used a placebo, all were in one country, and the authors rate the side-effect evidence low. It is the best human evidence for this herb, but it is for purified capsules, not the plain root.
Form and dose studied
Purified oligosaccharide capsules were tested, not the dried root or a tea. Ask a doctor or pharmacist about amounts.
Who was studied
Adults with mild to moderate depression in China.
Limits
No placebo group. One country. Capsule product, not the whole root. The depression-severity wording differs between the abstract's results (moderate) and its conclusion (mild to moderate).
Why researchers looked
Chinese medicine uses the root to "tonify kidney yang", which includes low mood and low drive. Chemists then isolated the sugar fraction (oligosaccharides) and tested it as a medicine.
Traditional use
Used in China and north-east Asia as a tonic for the kidneys and bones and for low mood (2018 review).
Proposed mechanism Animal research
Animal work suggests the oligosaccharides act on the brain growth-factor BDNF pathway and on gut bacteria. This is mouse research only.
A proposed mechanism does not show that the effect happens in people.
Depression needs proper care. Do not replace or stop an antidepressant without your prescriber. No study tested the root together with antidepressants.
Stress and depression-like behaviour (mouse studies)
Not enough evidenceIn stressed mice, the root sugars eased depression-like behaviour and changed brain and gut markers. This is animal work and does not show the same in people.
2 studiesPurified oligosaccharides given to mice. Not a human dose.
Studies, doses and limits
What the trials found
None for these mechanisms.
Results
Two recent mouse studies (2025, 2026) report less depression-like behaviour after the oligosaccharides. The abstracts give few numbers.
Effect sizes as reported
Not available
Why this rating
Insufficient: animal studies only.
Form and dose studied
Purified oligosaccharides given to mice. Not a human dose.
Who was studied
Mice.
Limits
Mice, not people. Little numeric detail in the abstracts.
Why researchers looked
To find out how the oligosaccharides might work, researchers gave them to mice stressed by chronic mild stress or by a stress hormone.
Traditional use
Ties in with the traditional use for low mood.
Proposed mechanism Animal research
Changes in the brain BDNF/TrkB/CREB pathway, gut bacteria, sex hormones and antioxidant markers were reported in mice.
A proposed mechanism does not show that the effect happens in people.
None to report from these studies.
Memory and Alzheimer's-type changes (lab and animal only)
Not enough evidenceA 2026 review says the root sugars show anti-Alzheimer effects in pre-clinical work. No human study was found.
2 studiesNot applicable.
Studies, doses and limits
What the trials found
No human study found.
Results
None to report in people.
Effect sizes as reported
Not applicable
Why this rating
Insufficient: a review statement about pre-clinical work.
Form and dose studied
Not applicable.
Who was studied
None in people.
Limits
We read only the review abstract.
Why researchers looked
Reviews list anti-Alzheimer activity among the root's lab findings.
Traditional use
Not a classic traditional use.
Proposed mechanism Lab
Not established.
A proposed mechanism does not show that the effect happens in people.
Not a reason to use the root for memory loss. See a doctor about memory problems.
Osteoporosis (bone thinning)
Very low certaintyA 2026 review found 11 trials, mostly of herbal mixtures, that reported benefit in osteoporosis. Few tested the root alone, so we cannot tell what the root itself does.
3 studiesMostly multi-herb formulas. Ask a doctor or pharmacist about amounts.
Studies, doses and limits
What the trials found
The 2026 review counted 11 clinical trials, mainly of herbal combinations, reporting benefit in primary osteoporosis with no evident adverse reactions. The abstract does not rate their quality. The authors ask for trials of the root alone.
Results
11 trials, mostly combinations; no numbers in the abstract.
Effect sizes as reported
Not given in the abstract.
Why this rating
Very low: mostly combination products, trial quality not stated in what we read, and a review of reviews and lab work rather than a new pooled analysis.
Form and dose studied
Mostly multi-herb formulas. Ask a doctor or pharmacist about amounts.
Who was studied
People with primary osteoporosis (China).
Limits
Combination formulas; abstract only; no bone-density numbers read.
Why researchers looked
The root is a classic Chinese bone tonic. Lab work suggests it affects the cells that build and remove bone.
Traditional use
Used in China to nourish the kidneys and strengthen bones.
Proposed mechanism Lab and animal
Extracts and compounds are reported to balance bone-building and bone-removing cells in lab and animal work. A nystose study (disc cells and mice) points to the Nrf2 antioxidant pathway.
A proposed mechanism does not show that the effect happens in people.
Osteoporosis treatment should be guided by a doctor. Do not stop bone medicines because of an herb.
Sexual function and male fertility
Not enough evidenceThe root is a traditional treatment for impotence and low fertility. We found no human trial. In stressed mice, the root sugars improved sperm numbers and sexual behaviour.
3 studiesPurified oligosaccharides in mice. Not a human amount.
Studies, doses and limits
What the trials found
No human trial was found in our search.
Results
Mouse study (2025): improved testis and epididymis tissue, sex hormones, sperm concentration and viability and sexual behaviour measures in stressed mice; the abstract gives no numbers.
Effect sizes as reported
Not available
Why this rating
Insufficient: traditional use plus mouse studies only.
Form and dose studied
Purified oligosaccharides in mice. Not a human amount.
Who was studied
Male mice.
Limits
Mice only; no numbers in the abstract.
Why researchers looked
"Strengthening kidney yang" in Chinese medicine includes sexual vigour and fertility.
Traditional use
A leading traditional use (2018 review). A consumer reference rates the evidence insufficient.
Proposed mechanism Animal research
In mice the root sugars changed sex hormones, testis antioxidant markers and sperm quality.
A proposed mechanism does not show that the effect happens in people.
Because it may change sex hormones in animals, people with hormone-sensitive conditions should ask their doctor first (see Safety).
Menopausal symptoms (as part of a six-herb formula)
Very low certaintyThe root is one of six herbs in Erxian decoction. A 2019 review of 16 studies saw promising signs but said the studies were too weak to judge.
1 studiesA decoction of six herbs. Ask a doctor or pharmacist.
Studies, doses and limits
What the trials found
16 studies (1,594 women). Versus hormone therapy: the overall effective rate was better, but Kupperman index results were contradictory across 5 studies. One study showed better hot flush scores than placebo. Only two studies reported adverse effects. The authors concluded the studies were low quality and could not be reproduced.
Results
Total effective rate better than hormone therapy (P<0.05); Kupperman results contradictory.
Effect sizes as reported
Not given in the abstract.
Why this rating
Very low: a combination formula, low-quality studies, and the authors themselves say the evidence cannot be assessed.
Form and dose studied
A decoction of six herbs. Ask a doctor or pharmacist.
Who was studied
Women with menopausal syndrome (China).
Limits
Cannot say anything about Morinda alone.
Why researchers looked
Erxian decoction is a well-known Chinese formula for menopause. It contains Morinda officinalis root.
Traditional use
Formula use only.
Proposed mechanism Unknown
Not separable for Morinda in a six-herb formula.
A proposed mechanism does not show that the effect happens in people.
Menopause treatment, especially hormone therapy, should be decided with a doctor.

The evidence
The research centre for Morinda root. 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, searched PubMed, read the abstract of each PubMed record cited, and checked names in GBIF and NCBI Taxonomy and compounds in PubChem. Regulator pages that could not be opened are marked not found or not verified.

Seven randomised trials (1,384 people) compared MOO capsules with antidepressants. Effect on depression was not different from antidepressants (risk ratio 0.99). Adverse events were also not different (risk ratio 0.84). The authors rated the adverse-event evidence as low quality. Efficacy RR 0.99 (95% CI 0.92-1.06); adverse events RR 0.84 (95% CI 0.65-1.07) (0.92-1.06) Methods, limits and fundingOutcomes: Response/efficacy and adverse events compared with antidepressants Limitations: No placebo comparison.

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 changes any 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".
Other 4
Hamilton depression score (HAMD-17)
No difference between groups in trials
A clinician-rated 17-question scale for depression severity. Lower is better.
Low certaintyResults and what it means

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 5
- Human safety data are thin. The best human evidence is for purified capsules in China. Adverse events were not different from antidepressants (risk ratio 0.84), but the authors rate that evidence low quality. In an 8-week trial, side effects were mild (mostly diarrhoea or constipation) and equal in both groups (5.56%). The osteoporosis review reports no evident adverse reactions, mainly from herbal combinations. Controlled trial 4 17 14
- This is not noni (Morinda citrifolia). Noni is a different species with its own safety record and its own page. The two roots are used interchangeably in Chinese medicine with no experimental support, and a chemical comparison could clearly separate them (25 compounds shared). Do not use noni safety or benefit claims for ba ji tian, or the reverse, and check the Latin name on the label. Observational 12 5
- Pregnancy and breastfeeding: avoid. No safety data in pregnancy or breastfeeding were found. A consumer drug reference advises avoiding it. Consumer reference 9 7
- Hormone-sensitive conditions: ask first. No human study measured hormones. In stressed male mice the root sugars changed sex hormones. Because of that, people with hormone-sensitive conditions (some breast, uterine or prostate cancers, endometriosis, fibroids) or on hormone treatment should ask their doctor before using it. This is a precaution, not a finding in people. Theoretical 13
- Liver: anthraquinones present, human effect unknown. The root contains anthraquinones (26 found in one analysis). We found no human report of liver injury from Morinda officinalis, and animal and cell work was reassuring, but no human liver or laxative study exists. Absence of evidence 12 10 7
Side effects 3
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Mild gut upset (diarrhoea, constipation) Both groups took the root sugars, so it does not separate the root from probiotics or chance. | 5.56% in each group of an 8-week trial | mild unknown | Controlled trial 17 |
| Irritability, insomnia and unpleasant sensations The 2018 review says very large amounts in lab work may cause these in individual cases; no significant adverse effect was reported at normal clinical use. | Not established | mild unknown | Review 16 |
| No side effects reported in most trials Many trials did not report adverse events, so "none reported" is not "none happened". | Not established | unknown unknown | Absence of evidence 14 4 |
Liver
No case of liver injury linked to Morinda officinalis was found in a PubMed search (including case-report terms). The root contains anthraquinones (26 in one analysis). We did not find any source that tested laxative or liver effects of these compounds from this plant in people. Rat studies of fermented root over 90 days showed no change in blood chemistry, and a two-herb liquid showed no liver harm in mice. A cell study found root extract did not harm normal liver cells. Noni (a different species) has liver injury reports; those do not apply to this plant. 10 3 12 7
How often. Unknown. No case reports found.
Monitoring. No source we read gives monitoring advice. Tell a doctor about yellow skin or eyes, dark urine, pale stools or severe tiredness.
This is a safety connection. It is not evidence that Morinda root supports liver health.
Medicines and supplements 5
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Antidepressants and other mood or sleep medicines drug | The trials compared the root capsules against antidepressants, not with them. The combination was not tested. | Unknown. Do not stack with antidepressants or swap one for the other without a prescriber. | No data Not enough evidence 4 | Tell your prescriber. Do not stop an antidepressant to use this herb. |
| Drugs moved by the P-glycoprotein pump (some heart, cancer, immune and other medicines) drug | Bajijiasu, a compound from the root, raised P-gp protein and activity in liver cells and mice. More P-gp could lower the blood level of drugs that pump uses. | Theoretical. Isolated compound at lab amounts; not shown in people. | Lab and animal Very low certainty 15 | Ask a pharmacist, especially with narrow-margin drugs such as ciclosporin or digoxin. |
| Diabetes medicines and blood sugar drug | A consumer reference warns the root might raise or lower blood sugar. No clinical or lab study of ours confirms this. | Unverified. | Consumer reference Very low certainty 9 | If you take diabetes medicine, tell your prescriber and watch blood sugar closely. |
| Hormone therapy and anti-hormone cancer treatments drug | Sex-hormone changes were seen in mice. | Theoretical. | Animal research Not enough evidence 13 | Ask your doctor first. |
| Noni (Morinda citrifolia) herb | Different species with a different safety record. Using both adds unknowns. | Not studied. | Theoretical Not enough evidence 12 | Do not treat the two as the same product. |
Who should check first 4
| Situation | Advice | Evidence |
|---|---|---|
| Pregnancy and breastfeeding | Avoid. No safety data. | Consumer reference 9 |
| Planned surgery | A consumer reference advises stopping at least 2 weeks before, because of possible blood-sugar effects. Unverified. | Consumer reference 9 |
| Hormone-sensitive conditions or hormone treatment | Ask your doctor first (precaution). | Theoretical 13 |
| Children | No data found. Avoid unless a doctor advises. | Absence of evidence 7 |
Overdose, product quality and regulators
Summary. Animal tests found no toxicity, but they used fermented root or a two-herb liquid, not the plain root in people.
Animal. Fermented root was not genotoxic in three tests; a single very large amount caused no deaths in mice and rats; a 90-day rat study showed no harm and a no-effect level of at least 8 g/kg a day. A two-herb liquid showed no acute, genotoxic or 28-day toxicity in mice.
Human doses studied. Trials of capsules ran up to 8 weeks.
High dose or long term signals. The 2018 review mentions irritability and insomnia in lab work at very large amounts.
Overdose response. Not described.
Genotoxicity. Fermented root negative in Ames, micronucleus and spermatocyte chromosome tests.
Toxic plant parts. Root is the medicinal part. Toxicity of other parts was not assessed.
One 2026 study cultured harmful-type bacteria from 40% of 30 dried Chinese herb batches across five herbs, including Morinda officinalis; Enterobacter was cultured from the Morinda samples. Per-herb rates were not given. Heavy metal and pesticide data were not found. Noni root is sometimes used in its place.
Microbes in dried root. Culture found bile-salt-resistant Gram-negative bacteria in 12 of 30 batches across five herbs, and Enterobacter in Morinda officinalis samples (not seen by sequencing). 8
Substitution with noni root. Roots of M. officinalis and M. citrifolia are used interchangeably in Chinese medicine, though no experiment supports this. Chemistry can tell them apart. 12

When to get medical help
- Yellow skin or eyes, dark urine, pale stools or severe tiredness.
- Rash, swelling of the face or lips, or trouble breathing.
- Low mood with thoughts of self-harm. Seek help at once and do not wait for a herb to work.
- Blood sugar very high or very low in someone with diabetes.
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 Morinda root (ba ji tian)?
Is it the same as noni?
Does it work for depression?
Can I take it with an antidepressant?
Nobody has tested the two together. Do not stop or swap an antidepressant yourself, and tell your prescriber.
Does it help bones or osteoporosis?
A 2026 review found 11 trials, mostly herbal mixtures, reporting benefit. The root on its own is not well tested, so the certainty is very low.
Does it help sexual function or fertility?
Is it safe in pregnancy or breastfeeding?
Is it safe with hormone-sensitive conditions?
Ask your doctor first. No human study measured hormones, but the root sugars changed sex hormones in mice.
Is it bad for the liver?
Does it affect blood sugar or diabetes medicines?
A consumer drug reference warns it might. No clinical or lab study we read confirms this. If you take diabetes medicine, tell your prescriber.
Does it interact with other medicines?
No human interaction study exists. A compound from the root raised the P-glycoprotein drug pump in cells and mice, which could in theory change levels of some drugs. Ask a pharmacist about your medicines.
