HelloPharmacist Scorecard of Laurel Leaf by Revive

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 a single active ingredient: bay leaf (also called laurel). Bay leaf is the dried leaf of a common culinary plant, and in this case it's been made into a liquid form for easier dosing.

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 Bay Leaf product and its label doesn't state a use — see Bay Leaf'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 bay leaf's effectiveness is not established in the data we hold. The ingredient has been studied for dandruff, diarrhea, painful periods, common cold, and boils, but the research to date is insufficient to rate whether it actually works for any of these uses.

That doesn't mean it won't help — it means we need better studies before we can say.

The evidence, ingredient by ingredient Bay Leaf

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.

Bay leaf is generally well tolerated when you use it in the small amounts you'd add to cooking. However, concentrated supplements like this one are less studied.

Food amounts are likely fine, but medicinal doses — which is what you'd be taking in supplement form — haven't been thoroughly tested for safety. When taken by mouth as a powder, it seems to be tolerated reasonably well, but swallowing whole, intact leaves can be risky and cause choking or intestinal perforation.

On the skin, bay leaf can trigger allergic reactions and contact dermatitis in some people. Breathing in bay leaf powder may also cause occupational asthma in sensitive individuals.

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 — Bay Leaf.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 335 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 pharmacist before starting if you take sedatives (including sleep aids), narcotic painkillers, or diabetes medications to lower blood sugar. Bay leaf can enhance the effects of sedatives and narcotics and may lower your glucose too much when combined with diabetes drugs.

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.

If you take sedatives, narcotic painkillers, or diabetes medications, you need to check with your pharmacist before trying this product — the interaction risk is real. Even if you don't take those drugs, the safety data on concentrated bay leaf supplements is thin, and we don't have solid evidence it works for the conditions it's marketed for.

Talk to your pharmacist about whether this makes sense for you.

Laurel Leaf by Revive: Common Questions

Does Laurel Leaf by Revive interact with any medications?
Yes. Based on its ingredients, Laurel Leaf has a known interaction with 335 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Laurel Leaf 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.
Is bay leaf safe to use while I'm taking diabetes medication?
Bay leaf can lower blood glucose on its own, so combining it with your diabetes drug could drop your blood sugar too low — causing shakiness, sweating, or worse. You'd need to monitor your glucose closely and possibly adjust your medication dose. Talk to your pharmacist or doctor before starting this product.
Can I take this if I use sleeping pills or painkillers?
Bay leaf can strengthen the effects of sedatives and narcotic painkillers, which means deeper drowsiness or breathing problems. The data advises against combining them. Check with your pharmacist before adding this supplement.
Does bay leaf actually work for dandruff, colds, or other conditions?
The evidence isn't established yet. Bay leaf has been studied for dandruff, diarrhea, painful periods, common cold, and boils, but we don't have enough reliable research to say whether it actually helps. That's why the ratings are insufficient evidence for all of them.
What are the side effects I should watch for?
Bay leaf is generally well tolerated in food amounts and as a powder supplement. On the skin, it can cause allergic reactions and contact dermatitis. Breathing in bay leaf powder may trigger asthma in sensitive people. The main risk with whole leaves is choking, which is why this product is in liquid form.
Is this safe if I'm pregnant or breastfeeding?
The safety data for concentrated bay leaf supplements during pregnancy and lactation isn't on file in our data. Food amounts are used routinely, but medicinal doses haven't been well studied. Talk with your doctor or pharmacist for personalized advice before using this product.
