HelloPharmacist Scorecard of Jambu by Herbal Hills

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.

From our pharmacy team — supplement deep dive

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 blend of jambolan seed extract and jambolan seed powder. Jambolan is a tropical fruit, and the seed is used in herbal medicine, primarily for its potential effects on blood sugar.

The capsule itself is made from HPMC (a plant-based material) and contains silicon dioxide as an inactive ingredient.

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 Jambolan product and its label doesn't state a use — see Jambolan'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 jambolan isn't established yet in the data we hold. For both diabetes and venous leg ulcers (varicose veins in the skin), the rating is insufficient reliable evidence to rate — meaning the studies so far aren't robust enough to say whether it actually works.

Animal research suggests it may lower blood glucose, but human data is limited.

The evidence, ingredient by ingredient Jambolan

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.

Jambolan fruit is widely eaten as a food, but concentrated supplement doses haven't been well studied, so caution is warranted. The safety data for medicinal amounts during pregnancy is not enough to recommend it, so avoid it in supplement form while pregnant.

Safety while breastfeeding is also unknown, so it's best avoided in supplement form during that time as well. No adverse effects were reported in the data we hold.

Side effects, ingredient by ingredient Jambolan

Meds to double-check

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 — Jambolan.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 186 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 Jambu, double-check with your pharmacist if you take any diabetes medications (including insulin and drugs like metformin), drugs processed by the liver enzyme CYP2C9 (such as certain blood thinners and NSAIDs), or sitagliptin (Januvia). Jambolan can affect how your body handles these.

Check your own medication Run your meds through the checker above

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.

Jambu might interest someone exploring herbal support for blood sugar, but the evidence isn't there yet. If you take diabetes medications, blood thinners, or any drug metabolized by your liver, check with us before you start — the interaction potential is real.

Pregnant or breastfeeding? Skip it.

Jambu seed extract & Jambu seed powder blend3 drug types · 186 drugs

Antidiabetes Drugs

Animal research shows that jambolan seed and bark extracts can lower blood glucose levels. Theoretically, jambolan might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.

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

There is some in vitro evidence that jambolan can inhibit CYP2C9. Theoretically, concomitant use of jambolan with CYP2C9 substrates may increase levels of drugs metabolized by CYP2C9.

Likelihood Possible Evidence D
Sitagliptin (Januvia)

Animal research shows that jambolan seed extract reduces the sitagliptin maximum plasma concentration and area under the curve by 39% and 22%, respectively. However, blood glucose levels were actually reduced to a greater extent in mice taking jambolan and sitagliptin in combination when compared with either product taken alone. Theoretically, jambolan seed extract might alter the clearance of sitagliptin, although this may not alter the clinical effects of sitagliptin.

Jambu by Herbal Hills: Common Questions

Does Jambu by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Jambu has a known interaction with 186 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Jambu 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 Jambu if I'm pregnant or breastfeeding?
No — the safety data advises against it. Concentrated supplement doses haven't been studied enough during pregnancy, and safety while breastfeeding is unknown. Talk with your doctor or pharmacist before using any supplements in these situations.
What is jambolan supposed to do?
It's traditionally used for blood sugar support, but the evidence isn't established yet in our data. Animal research suggests the seed can lower blood glucose, but human studies are limited.
Is jambolan safe to eat as a fruit?
Yes — the fruit itself is widely eaten as food. This product uses concentrated seed extract and powder, though, which isn't as well studied as the whole fruit, so we recommend caution.
Why does this product interact with so many medications?
Most of the interactions come from one mechanism: jambolan may slow how your liver processes drugs metabolized by the enzyme CYP2C9. That enzyme handles over 100 medications, which is why the count is high. The other major concern is blood sugar, since jambolan itself can lower it.
Can I take Jambu if I'm on diabetes medication?
Not without checking first. Jambolan can lower blood sugar on its own, so using it with diabetes drugs may increase your risk of low blood sugar (hypoglycemia). You'll need to monitor your glucose closely, and your doctor may need to adjust your dose. Talk to your pharmacist before starting.
