HelloPharmacist Scorecard of Organic Guava Leaf Liquid Extract by Herbal Goodness

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

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 is a straightforward single-ingredient product: one active ingredient, organic guava leaf extract, in a liquid form. The extract is suspended in organic vegetable glycerin and purified water.

Guava leaf extract is the traditional part of the guava plant used in supplements — different from eating fresh guava fruit, which is a common food. The inactive ingredients here are the glycerin and water that make up the liquid base.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: promote healthy blood sugar and heart support.
  • We looked for evidence on: blood sugar regulation, cardiovascular health, cholesterol management, gastrointestinal function.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold doesn't establish whether guava leaf extract works for any of its claimed uses. We don't have reliable data on its effects for diarrhea, gingivitis (gum inflammation), hypertension (high blood pressure), or knee pain.

That doesn't mean it doesn't work — just that the data we have isn't strong enough to say either way.

The evidence, ingredient by ingredient Guava

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.

Orally, guava leaf extract may cause transient abdominal pain or nausea in some people. If applied to the skin, it can cause contact dermatitis (skin irritation), and there's a report of it worsening eczema in one person who bathed with guava leaf tea.

Guava fruit as food is generally well tolerated, but concentrated leaf extracts and supplements are less studied overall. There isn't enough safety information on leaf supplements to be fully confident, so caution is warranted if you're considering regular use.

Side effects, ingredient by ingredient Guava

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 — Guava.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take antidiabetes drugs like glimepiride, confirm with your doctor or pharmacist first — guava leaf extract may increase the risk of low blood sugar (hypoglycemia) and your dose may need adjusting.

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.

This product is a single guava leaf extract in liquid form. If you take blood sugar medications, you'll want to talk with your doctor or pharmacist before starting it, because guava may lower your blood sugar further.

For other uses, the evidence isn't established in our data. Check your exact medications before you begin.

Antidiabetes Drugs

Theoretically, concomitant use with antidiabetes drugs might have additive effects and increase the risk of hypoglycemia. Animal research shows that guava leaf extract or guava fruit can have hypoglycemic effects. Monitor blood glucose levels closely. Medication dose adjustments may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (Diabeta, Glynase PresTab, Micronase), insulin, metformin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Organic Guava Leaf Liquid Extract by Herbal Goodness: Common Questions

Does Organic Guava Leaf Liquid Extract by Herbal Goodness interact with any medications?
Yes. Based on its ingredients, Organic Guava Leaf Liquid Extract has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Guava Leaf Liquid Extract 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 this if I'm breastfeeding?
Yes — guava leaf extract is rated likely safe during lactation. That said, guava leaf supplements are less studied overall than guava fruit as a food, so if you have specific concerns about your situation, a quick check with your pharmacist or doctor is a good idea.
What are the side effects?
Taken by mouth, some people report transient abdominal pain or nausea. If you apply it to skin, it can cause contact dermatitis (skin irritation), and in one reported case it worsened eczema, though that's uncommon.
Does this actually work for diarrhea, high blood pressure, or gum disease?
We don't have reliable evidence in our data to say either way. The science on guava leaf extract for those uses isn't established enough for us to make a claim.
Why is this a liquid extract instead of a whole leaf?
A liquid extract concentrates the active compounds from the leaf into a smaller volume, making it easier to dose and consume. The trade-off is that concentrated supplements like this one are less studied for safety than guava as a whole food.
