HelloPharmacist Scorecard of Cubeb 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.

This product contains one active ingredient: a wildcrafted cubeb extract. Cubebs are a pepper-like spice traditionally used in cooking and herbal practice.

The liquid is carried in vegetable palm glycerin, pharmaceutical-grade alcohol, and purified water.

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 Cubebs product and its label doesn't state a use — see Cubebs'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.

We hold no effectiveness data for cubeb extract in our records.

The evidence, ingredient by ingredient Cubebs

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Cubeb in small culinary amounts is likely fine, but the safety of medicinal doses and cubeb essential oil hasn't been well studied. The safety data advises against medicinal use during pregnancy and while breastfeeding because there isn't enough information to know whether it's safe for your baby.

If you're pregnant or nursing and considering this supplement, talk with your doctor or pharmacist for personalized guidance.

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 — Cubebs.
  • The most serious interaction on file is rated Moderate.
  • For scale: 666 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 before starting if you take drugs metabolized by the liver enzyme CYP3A4 (including cholesterol and heart medications, certain antibiotics, and immunosuppressants), H2-blockers, antacids, or proton pump inhibitors (acid-reflux medications). The CYP3A4 interaction is Moderate; the stomach-acid effects are Minor but affect multiple drug types.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Cubeb extract may interact with medications that your liver processes or that control stomach acid — a fairly broad group. If you take any prescription drugs, especially cholesterol medications, antibiotics, heart medications, or acid-reflux treatments, check with your doctor or pharmacist before adding this product.

Cytochrome P450 3A4 (Cyp3A4) Substrates

Several compounds isolated from cubebs can inhibit cytochrome P450 3A4 (CYP3A4) in vitro. So far, this effect has not been reported in humans. Theoretically, cubebs might increase the effects and side effects of drugs metabolized by CYP3A4. These include lovastatin (Mevacor), clarithromycin (Biaxin), cyclosporine (Neoral, Sandimmune), diltiazem (Cardizem), estrogens, indinavir (Crixivan), triazolam (Halcion), and numerous others.

Likelihood Possible Evidence D
Antacids

Theoretically, due to reports that cubebs increases stomach acid, cubebs might decrease the effectiveness of antacids.

Likelihood Possible Evidence D
H2-Blockers

Theoretically, due to reports that cubebs increases stomach acid, cubebs might decrease the effectiveness of H2-blockers. The H2 blockers include cimetidine (Tagamet), ranitidine (Zantac), nizatidine (Axid), and famotidine (Pepcid).

Likelihood Possible Evidence D
Proton Pump Inhibitors (Ppis)

Theoretically, due to reports that cubebs increases stomach acid, cubebs might decrease the effectiveness of PPIs. PPIs include omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), pantoprazole (Protonix), and esomeprazole (Nexium).
