HelloPharmacist Scorecard of Mu Dan Pi by Herbal Terra

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: certified organic Mu Dan Pi — the dried bark of Paeonia suffructicosa, delivered as a liquid extract. Mu Dan Pi is the Latin name for tree peony bark, a plant used in traditional Chinese medicine.

The product also includes menstruum, a liquid used to extract and preserve the herb.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Peony product and its label doesn't state a use — see Peony's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold for peony bark does not establish it as effective for any of the conditions listed — aging skin, anal fissures, atherosclerosis, chronic fatigue syndrome, cirrhosis, or migraine headache. All are rated as having insufficient reliable evidence to rate.

That doesn't mean peony has no uses, only that the data we hold don't support these particular claims.

The evidence, ingredient by ingredient Peony

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Peony is generally well tolerated for short-term use, though high-quality safety data are limited. The most common side effects when taken by mouth are gastrointestinal: abdominal bloating, loss of appetite, diarrhea, nausea, and general stomach discomfort — diarrhea occurred in about 5% of participants taking a peony extract at high doses over 24 weeks.

On the skin, it may cause dermatitis. There is one case report of increased bleeding (easy gum bleeding, nosebleeds, skin bruising) in a person on warfarin who switched brands of a Chinese herbal product containing peony.

During pregnancy, the safety data advise against use. While breastfeeding, there isn't enough reliable information to know whether it's safe, so talk with your doctor or pharmacist for personalized advice.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Peony.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 812 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your pharmacist or doctor if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel), birth control pills or estrogen replacement, phenytoin (an anti-seizure drug), clozapine (an antipsychotic), or any other medication broken down by the liver. Peony has documented Moderate-severity interactions across all these categories.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Mu Dan Pi may appeal to someone looking to explore traditional Chinese herbal medicine, but the evidence for its effectiveness isn't established in our data. If you take blood thinners, birth control, hormone therapy, anti-seizure medication, or certain psychiatric drugs, check with your doctor or pharmacist before starting — the interactions could matter.

Pregnant people should avoid it; those breastfeeding should confirm safety with their own healthcare provider first.

Anticoagulant/Antiplatelet Drugs

Theoretically, combining peony with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that peony might have antiplatelet, anticoagulant, and antithrombotic effects.

Likelihood Possible Evidence D
Clozapine (Clozaril)

Theoretically, peony might increase the levels and clinical effects of clozapine.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on cytochromes P450 (CYP) 1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro and animal research shows that peony extract has estrogenic activity. Concomitant use might also increase the risk for estrogen-related adverse effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.
In vitro and animal research shows that peony extract has estrogenic activity. Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Theoretically, peony might reduce the levels and clinical effects of phenytoin.
Animal research shows that taking peony root reduces levels of phenytoin. Some researchers suggest that peony root might affect cytochrome P450 (CYP) 2C9, which metabolizes phenytoin. However, preliminary research in humans shows that peony root does not alter levels of losartan (Cozaar), which is also metabolized by CYP2C9.

Mu Dan Pi by Herbal Terra: Common Questions

Does Mu Dan Pi by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Mu Dan Pi has a known interaction with 811 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mu Dan Pi contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Mu Dan Pi if I'm on warfarin or another blood thinner?
Not without checking first. Peony may increase bleeding risk on top of what your blood thinner already does — there's even a case report of significant bleeding in someone on warfarin who used a Chinese herbal product containing peony. Talk with your doctor or pharmacist before combining them.
Will this interfere with my birth control?
Possibly. Peony has estrogenic activity, which means it could theoretically compete with or add to how your contraceptive works. Check with your doctor or pharmacist to be sure it's safe to use together.
What side effects might I experience?
Most common are stomach-related: bloating, appetite loss, diarrhea, and nausea. In one study, about 5% of people taking a high-dose peony extract developed diarrhea over 24 weeks. On the skin, it can cause irritation.
Is it safe to use during pregnancy?
No — the safety data advise against it. If you're planning to become pregnant or already are, skip this product and talk with your doctor about safer options.
Can I breastfeed while taking Mu Dan Pi?
There isn't enough reliable information to know either way. Talk with your doctor or pharmacist about whether it's right for you while breastfeeding.
Does peony actually work for the conditions on the label?
The evidence in our data doesn't establish it as effective for any of them — aging skin, anal fissures, atherosclerosis, chronic fatigue, cirrhosis, or migraines are all rated as having insufficient evidence to rate.
