What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 6 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,360 mg) without saying how much of each component you get.

Jian Pi Wan contains six active ingredients delivered as extracts: citrus reticulata (tangerine) peel, codonopsis root, atractylodes rhizome, bitter orange fruit, barley fruit, and hawthorn fruit. These are combined in a proprietary blend and formed into tablets or pills.

The product also includes inactive ingredients—magnesium silicate, dextrin, and china wax—that serve as binders and fillers.

Does it work?

Strong evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Barley) (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Likely Effective" (Barley) (Natural Medicines).

The evidence for most ingredients in this product is incomplete. Barley fruit extract shows likely effectiveness for high cholesterol and heart disease.

Tangerine peel, codonopsis, atractylodes, bitter orange, and hawthorn all lack enough reliable evidence to establish whether they work for the conditions they are traditionally used for. The data we hold does not show proven benefit for these ingredients in treating their claimed purposes.

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Barley is well tolerated as food but contains gluten. Tangerine fruit is safe to eat, though concentrated extracts need caution.

Bitter orange is potentially unsafe at supplement doses—it can raise blood pressure and heart rate, especially when combined with caffeine or other stimulants, and rare serious effects like heart attack and stroke have been reported. Codonopsis and atractylodes are traditionally used but have limited safety data; very large doses of codonopsis (30–60 grams) may cause chest pain, arrhythmia, or throat pain, and allergic reactions including anaphylaxis are possible.

Hawthorn is generally well tolerated but requires medical supervision if you have a heart condition. For pregnancy and breastfeeding: codonopsis and atractylodes should be avoided (the safety data advises against it), barley food is likely safe but concentrated supplements are not well studied, bitter orange should be avoided in pregnancy and breastfeeding, hawthorn should be avoided (not enough data), and tangerine fruit is fine but concentrated extracts should be used cautiously.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 6 of the 6 matched ingredients can interact with medications — Hawthorn, Codonopsis, Barley, Bitter Orange, Atractylodes, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications.
  • For scale: 1,087 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 Jian Pi Wan, check with your doctor or pharmacist if you use any of these: medications for depression (especially MAOIs), heart or blood pressure drugs (especially nitrates, beta-blockers, calcium channel blockers, or phosphodiesterase-5 inhibitors like sildenafil), blood thinners or antiplatelet drugs, diabetes medications, digoxin, sedatives like midazolam, cough suppressants like dextromethorphan, stimulants, or caffeine supplements. The bitter orange and hawthorn in this product carry Major-severity risks with certain cardiac drugs that could cause dangerous drops in blood pressure or raised blood pressure and heart rate.

For each ingredient in Jian Pi Wan with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Citrus aurantium Fruit-Immature Extract13 drug types · 957 drugs

Midazolam (Versed)

Bitter orange might increase blood levels of midazolam.
One small clinical study shows that bitter orange juice can increase midazolam levels, likely through inhibition of cytochrome P450 3A4 (CYP3A4). Theoretically, bitter orange might increase the risk of midazolam-related adverse effects.

Likelihood Probable Evidence B
Monoamine Oxidase Inhibitors (Maois)

Theoretically, taking MAOIs with synephrine-containing bitter orange preparations might increase the hypertensive effects of synephrine, potentially leading to hypertensive crisis.
Bitter orange contains tyramine, octopamine, and synephrine, which are MAO substrates.

Likelihood Probable Evidence D
Antidiabetes Drugs

Theoretically, bitter orange might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Some clinical research shows that drinking a tea containing bitter orange and Indian snakeroot reduces fasting and postprandial glucose levels in patients with type 2 diabetes who are using antidiabetes drugs. However, it is unclear if these effects are due to bitter orange, Indian snakeroot, or the combination. An animal study also shows that p-synephrine in combination with gliclazide , a sulfonylurea, causes an additional 20% to 44% decrease in glucose levels when compared with gliclazide alone.

Likelihood Possible Evidence B
Caffeine

Bitter orange might increase blood pressure and heart rate when taken with caffeine.
Small clinical studies show that taking bitter orange in combination with caffeine can increase blood pressure and heart rate in otherwise healthy normotensive adults. Theoretically, this might increase the risk of serious cardiovascular adverse effects.

Likelihood Possible Evidence B
Colchicine

Bitter orange might affect colchicine levels.
Colchicine is a substrate of P-glycoprotein and cytochrome P450 3A4 (CYP3A4). Bitter orange has been reported to inhibit CYP3A4 and increase levels of CYP3A4 substrates. However, one small clinical study in healthy adults shows that drinking bitter orange juice 240 mL twice daily for 4 days and taking a single dose of colchicine 0.6 mg on the 4th day decreases colchicine peak serum levels by 24%, time to peak serum level by 1 hour, and overall exposure to colchicine by 20%. The clinical significance of this finding is unclear.

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

Bitter orange might increase levels of drugs metabolized by CYP3A4.
Small clinical studies suggest that single or multiple doses of freshly squeezed bitter orange juice 200-240 mL can inhibit CYP3A4 metabolism of drugs, causing increased drug levels and potentially increasing the risk of adverse effects. However, the extent of the effect of bitter orange on CYP3A4-mediated drug interactions is unknown. Some evidence suggests that bitter orange selectively inhibits intestinal CYP3A4, but not hepatic CYP3A4. Its effect on P-glycoprotein, which strongly overlaps with CYP3A4 interactions, is unclear. One small clinical study shows that drinking 8 ounces of freshly squeezed bitter orange juice has no effect on cyclosporine, which seems to be more dependent on hepatic CYP3A4 and P-glycoprotein than intestinal CYP3A4.

Likelihood Possible Evidence B
Dextromethorphan (Robitussin Dm, Others)

Bitter orange might increase blood levels of dextromethorphan.
One small clinical study shows that bitter orange juice increases dextromethorphan levels, likely through cytochrome P450 3A4 (CYP3A4) inhibition. Theoretically, bitter orange might increase the risk for dextromethorphan-related adverse effects.

Likelihood Possible Evidence B
Felodipine (Plendil)

Bitter orange might increase blood levels of felodipine.
One small clinical study shows that bitter orange juice increases felodipine levels, likely through cytochrome P450 3A4 (CYP3A4) inhibition. Theoretically, bitter orange might increase the risk for felodipine-related adverse effects.

Likelihood Probable Evidence B
Indinavir (Crixivan)

Bitter orange might increase blood levels of indinavir.
One small clinical study shows that bitter orange juice slightly increases indinavir levels, but this effect is likely to be clinically insignificant. Bitter orange selectively inhibits intestinal cytochrome P450 3A4 (CYP3A4); however, the metabolism of indinavir seems to be more dependent on hepatic CYP3A4. The effect of bitter orange on other protease inhibitors has not been studied.

Likelihood Possible Evidence B
Qt Interval-Prolonging Drugs

Theoretically, bitter orange might have an additive effect when combined with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias.
One case report suggests that taking bitter orange in combination with other stimulants such as caffeine might prolong the QT interval in some patients.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Bitter orange juice might increase blood levels of sildenafil.
A small clinical study in healthy adult males shows that drinking freshly squeezed bitter orange juice 250 mL daily for 3 days and taking a single dose of sildenafil 50 mg on the 3rd day increases the peak plasma concentration of sildenafil by 18% and the overall exposure to sildenafil by 44%. Theoretically, this may be due to inhibition of cytochrome P450 3A4 by bitter orange.

Likelihood Probable Evidence B
Stimulant Drugs

Theoretically, bitter orange might increase the risk of hypertension and adverse cardiovascular effects when taken with stimulant drugs.
Bitter orange appears to have stimulant effects.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, bitter orange might increase levels of drug metabolized by CYP2D6.
In vitro research shows that octopamine, a constituent of bitter orange, weakly inhibits CYP2D6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Citrus aurantium Fruit-Immature Extract full monograph & interactions

Atractylodes macrocephala Rhizome Extract5 drug types · 801 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, atractylodes might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Laboratory research suggests that atractylenolides II and III, constituents of atractylodes, reduce platelet activation. So far, this has not been shown in humans.

Likelihood Possible Evidence D
Aromatase Inhibitors

Theoretically, atractylodes may have an additive effect when used with other aromatase inhibitors.
Laboratory research suggests that atractylodes and its constituents exhibit aromatase inhibitor effects.

Likelihood Possible Evidence D
Hexobarbital

Theoretically, taking atractylodes may prolong the therapeutic and adverse effects of hexobarbital.
In animals, atractylodes has been shown to prolong the effects of hexobarbital. These effects have not been shown in humans.

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

Theoretically, atractylodes might decrease the levels of CYP1A2 substrates.
In animals, atractylodes administered at high doses has been shown to induce CYP1A2 activity. This effect has not been shown in humans.

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

Theoretically, atractylodes might increase the levels of CYP3A4 substrates.
In animals, atractylodes administered at high doses has been shown to inhibit CYP3A1 activity, which is a homolog to the human CYP3A4 enzyme. This effect has not been shown in humans.

Likelihood Possible Evidence D
Atractylodes macrocephala Rhizome Extract full monograph & interactions

Citrus reticulata Peel Extract2 drug types · 643 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

In vitro, tangeretin, a constituent of tangerine, induces a 52% increase in the metabolism of midazolam by cytochrome P450 3A4 (CYP3A4). This suggests that tangeretin may stimulate CYP3A4 activity. However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam, a CYP3A4 substrate. Theoretically, tangerine juice might increase CYP3A4 activity and decrease levels of drugs metabolized by this enzyme. However, this effect is unlikely.
Some drugs metabolized by CYP3A4 include amitriptyline (Elavil), amiodarone (Cordarone), citalopram (Celexa), felodipine (Plendil), lansoprazole (Prevacid), ondansetron (Zofran), prednisone (Deltasone, Orasone), sertraline (Zoloft), sibutramine (Meridia), and many others.

Likelihood Unlikely Evidence B
Midazolam (Versed)

In vitro, tangeretin, a constituent of tangerine, appears to increase the metabolism of midazolam in human liver microsomes by up to 52%. However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam. Theoretically, tangerine juice might increase the metabolism and reduce the effects of midazolam. However, this effect is unlikely.

Likelihood Unlikely Evidence B
Citrus reticulata Peel Extract full monograph & interactions

Codonopsis pilosula Root Extract3 drug types · 211 drugs

Abiraterone (Zytiga)

Theoretically, taking codonopsis root with abiraterone might reduce the levels and therapeutic effects of abiraterone.
Animal research in rats shows that intragastric administration of codonopsis root along with abiraterone every 2 days for 2 weeks seems to increase the clearance of abiraterone and reduce the overall exposure and time to maximum concentration. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, codonopsis liquor might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
A small clinical study in adults with coronary heart disease shows that consuming Codonopsis pilosula liquor for 4 weeks inhibits platelet aggregation but does not affect tissue-type plasminogen activator (t-PA) or plasminogen activator inhibitor (PAI).

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, codonopsis might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Laboratory and animal research suggest that codonopsis has antidiabetic effects.

Codonopsis pilosula Root Extract full monograph & interactions

Crataegus pinnatifida fruit extract6 drug types · 191 drugs

Nitrates

Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Probable Evidence D
Phosphodiesterase-5 Inhibitors

Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.

Likelihood Possible Evidence D
Beta-Blockers

Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.

Likelihood Possible Evidence D
Calcium Channel Blockers

Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.

Likelihood Possible Evidence D
Crataegus pinnatifida fruit extract full monograph & interactions

Hordeum vulgare Fruit Extract1 drug type · 1 drug

Triclabendazole (Egaten)

Theoretically, barley might decrease the clinical effects of triclabendazole.
Animal research suggests that a diet supplemented with barley can reduce the bioavailability of triclabendazole when taken concomitantly. This effect has not been shown in humans.

Jian Pi Wan by Min Shan: Common Questions

Does Jian Pi Wan by Min Shan interact with any medications?
Yes. Based on its ingredients, Jian Pi Wan has a known interaction with 1,086 medications, including 24 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Jian Pi Wan contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this if I'm pregnant or breastfeeding?
The safety data advises against codonopsis and atractylodes during pregnancy and breastfeeding. Barley as food is likely safe in pregnancy but concentrated supplements are not well studied. Bitter orange and hawthorn should be avoided because there isn't enough data to know they're safe. Talk with your doctor or pharmacist about whether this product is right for you.
What is bitter orange, and why is it in this product?
Bitter orange (Citrus aurantium) is an immature citrus fruit extract traditionally used for digestion and energy. It contains stimulant compounds like synephrine that can raise blood pressure and heart rate—so it needs caution, especially if you have heart disease or high blood pressure.
Does this product have any gluten?
Yes—barley, one of the active ingredients, contains gluten. If you have celiac disease or gluten sensitivity, you should avoid this product or check with your doctor first.
What are the most common side effects?
The ingredients show few common side effects when used alone, but barley can cause bloating, gas, and abdominal distension. Bitter orange may raise blood pressure and heart rate, especially in combination with caffeine. Allergic reactions are rare but possible with codonopsis.
Is barley in this product proven to work?
Yes—barley fruit extract is likely effective for high cholesterol and heart disease based on the evidence we hold. The other ingredients lack enough reliable evidence to say whether they work for their traditional uses.
Can I take this with caffeine or energy drinks?
You should check with your doctor or pharmacist first. Bitter orange in this product can combine with caffeine to raise blood pressure and heart rate, which could be risky depending on your heart health.
