HelloPharmacist Scorecard of Huang Bo by Hawaii Pharm

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.

Huang Bo contains one active ingredient: phellodendron chinense bark extract in dry form. Phellodendron is a traditional herbal remedy used in Asian medicine, and this product delivers it as a liquid extract mixed with alcohol, water, and glycerin as inactive carrier ingredients.

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 Phellodendron product and its label doesn't state a use — see Phellodendron'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 for phellodendron is not established for the uses we have data on — acne, benign prostatic hyperplasia (prostate enlargement), diabetes, obesity, osteoarthritis, and peptic ulcers all show insufficient reliable evidence to rate its effectiveness. We hold no data on how well this product works for any condition.

The evidence, ingredient by ingredient Phellodendron

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.

Phellodendron has been used short-term in traditional medicine, but human safety data are limited. Avoid this product during pregnancy — berberine-containing herbs are rated likely unsafe.

Breastfeeding is not safe either, since berberine can pass into breast milk and may harm infants. Adverse effects are rare in the data we hold.

A combination product containing phellodendron and magnolia reported single cases of sexual dysfunction, shaking hands, numbness around the mouth, fatigue, headache, and heartburn in clinical trials, though it's unclear whether phellodendron was the cause.

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 — Phellodendron.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,161 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.

Check with your doctor or pharmacist before taking this product if you use CNS depressants (sedating medications), antihypertensive drugs (blood pressure medications), blood thinners or antiplatelet drugs, diabetes medications or metformin, or any drugs metabolized by CYP2D6, CYP2C9, or CYP3A4 enzymes — these can include many common prescriptions. Use the medication search tool on this page to verify your exact medications.

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.

Huang Bo is a single-ingredient phellodendron extract with substantial interaction potential — especially with blood pressure drugs, blood thinners, diabetes medications, and drugs your liver metabolizes. If you take any prescription medication, check it against this product's interactions before starting.

Pregnant and breastfeeding women should avoid it. Talk with your doctor or pharmacist about whether it's appropriate for you.

Phellodendron chinense Bark Extract, Dry14 drug types · 1,160 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, phellodendron might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Phellodendron contains berberine. In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, phellodendron might also inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, phellodendron may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Phellodendron contains berberine. Clinical research shows that berberine may lower blood glucose levels. Theoretically, phellodendron might also lower blood glucose levels.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, phellodendron might have additive effects with antihypertensive drugs.
Phellodendron contains berberine. Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone. Theoretically, phellodendron might also reduce blood pressure.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, phellodendron might increase the sedative effects of CNS depressants.
Phellodendron contains berberine. Animal research suggests that berberine may have sedative effects. Theoretically, phellodendron might also have CNS depressants effects.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, phellodendron might increase blood levels of cyclosporine.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can reduce metabolism of cyclosporine and increase serum levels, likely through inhibition of cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine. Theoretically, phellodendron might also reduce the metabolism of cyclosporine.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2C9.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, phellodendron might also inhibit CYP2C9.

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

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2D6.
Phellodendron contains berberine. In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, phellodendron might also inhibit CYP2D6.

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

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP3A4.
Phellodendron contains berberine. In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, phellodendron might also inhibit CYP3A4.

Likelihood Possible Evidence D
Dextromethorphan (Robitussin Dm, Others)

Theoretically, phellodendron may increase serum levels of dextromethorphan.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan. Theoretically, phellodendron may also inhibit the metabolism of dextromethorphan.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, phellodendron might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Phellodendron contains berberine. Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan. Theoretically, phellodendron might also inhibit the metabolism of losartan.

Likelihood Possible Evidence D
Metformin (Glucophage)

Theoretically, phellodendron might increase the therapeutic and adverse effects of metformin.
Phellodendron contains berberine. In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin. It is unclear if phellodendron might have this same effect.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, phellodendron might reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam. Theoretically, phellodendron might also inhibit the metabolism of midazolam.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, phellodendron might increase the sedative effect of pentobarbital.
Phellodendron contains berberine. Animal research shows that berberine can prolong pentobarbital-induced sleeping time. Theoretically, phellodendron might increase the sedative effects of pentobarbital.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, phellodendron might increase blood levels of tacrolimus.
Phellodendron contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL. It is unclear if phellodendron might have this same effect.

Huang Bo by Hawaii Pharm: Common Questions

Does Huang Bo by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Huang Bo has a known interaction with 1,160 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Huang Bo 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 Huang Bo while pregnant?
No — berberine-containing herbs like phellodendron are rated likely unsafe during pregnancy based on safety data. Avoid this product if you're pregnant or planning to become pregnant. Talk with your doctor about alternatives.
Is it safe to breastfeed while taking Huang Bo?
No — berberine passes into breast milk and may be harmful to infants. Safety data advise against this product while breastfeeding. Discuss safer options with your doctor or pharmacist.
What is phellodendron used for?
Phellodendron is a traditional herbal remedy, and we have data on its proposed uses for acne, prostate enlargement, diabetes, weight management, osteoarthritis, and peptic ulcers. However, the evidence isn't strong enough to rate its effectiveness for any of these yet.
Does Huang Bo work?
The evidence we hold shows insufficient reliable evidence to rate phellodendron's effectiveness for the conditions it's traditionally used for. You should check with your doctor about whether it's the right choice for your needs.
What are the side effects?
In clinical trials, a combination product with phellodendron and magnolia reported rare single cases of sexual dysfunction, hand shaking, mouth numbness, fatigue, headache, and heartburn — though it's unclear if phellodendron was responsible. Human safety data overall are limited.
