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 product contains one active ingredient: organic guava leaf extract. The formula also includes organic vegetable glycerin, organic guava, and purified water as inactive ingredients that keep it stable and in liquid form.

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: improve sleep quality and blood sugar support.
  • We looked for evidence on: blood sugar regulation, sleep quality, glycemic control.
  • 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 diarrhea, gingivitis, hypertension, or knee pain — the data on file rates all of these as insufficient reliable evidence to make a call. That doesn't mean it doesn't work; it means we don't have solid human trial data to confirm it.

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.

Guava fruit as a food is well tolerated, but this product is a concentrated leaf extract, and concentrated leaf supplements are less well studied overall. Taken by mouth, guava leaf extract may cause transient belly pain or nausea.

Applied to skin, it may cause contact dermatitis (a localized rash) and, in at least one reported case, worsened existing eczema. People with eczema or atopic dermatitis should use this product with extra caution, especially topically.

Side effects, ingredient by ingredient Guava

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.

Check with your doctor or pharmacist before combining this product with antidiabetes drugs (medications that lower blood sugar). Guava leaf extract can have a blood-sugar-lowering effect, and using both together may increase your risk of low blood sugar.

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.

Guava leaf extract is generally well tolerated orally, but if you take a blood sugar medication, the two together could lower your glucose more than intended. Talk with your doctor or pharmacist before starting it — they can help you figure out whether a dose adjustment is needed or whether this product is right for you.

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 while breastfeeding?
Guava leaf extract is rated likely safe during lactation according to the data we hold. That said, concentrated leaf supplements are less studied than whole guava fruit, so discuss it with your doctor or pharmacist to be sure it's right for your situation.
Will this help with diarrhea?
The evidence we have doesn't establish whether guava leaf extract works for diarrhea — it's rated insufficient reliable evidence. You might see it marketed for this, but we can't confirm it from the clinical data on file.
What side effects might I notice?
If you take it by mouth, you might experience transient belly pain or nausea. If you apply it to skin, you could develop a localized rash. People with eczema should be especially cautious, since one reported case showed worsening of symptoms with topical use.
Is this safe to use long-term?
Guava fruit as a food is fine, but concentrated leaf supplements like this one aren't as well studied. The safety data we hold suggests caution with long-term use and recommends talking with your doctor or pharmacist before making it a regular part of your routine.
What's the difference between guava fruit and guava leaf extract?
Whole guava fruit is generally safe as food, but this product is a concentrated extract from the leaves — a different form with less research behind it. Concentrated supplements are processed differently and haven't been studied as thoroughly as the whole food.
