HelloPharmacist Scorecard of Laurel (Bay) 450 mg by TerraVita Premium Collection

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 Jul 11, 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: bay laurel (bay leaf), at 450 mg per capsule. The inactive ingredients are gelatin and water — the capsule shell and a small amount of liquid used in manufacturing.

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 on bay leaf for the conditions listed — dandruff, diarrhea, menstrual cramps (dysmenorrhea), and the common cold — is not established enough for us to rate it. The data we hold shows insufficient reliable evidence for any of these uses.

If you're considering this supplement for one of these reasons, talk with us or your doctor about whether the science supports it for your situation.

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 in food amounts — the kind you'd use to season a pot of soup — is generally well tolerated. However, concentrated supplements like this one are less studied in people.

The whole, unbroken leaf can cause serious problems: choking or, rarely, a perforated intestinal lining if swallowed intact. Inhaling bay leaf powder may trigger asthma symptoms in occupationally exposed people.

Allergic reactions and contact dermatitis (a skin rash) have been reported, especially with topical use. Pregnancy and lactation data for this product are not on file — talk with your pharmacist or doctor for personalized advice before use during pregnancy or while breastfeeding.

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 your exact medications before starting, especially sedatives (including sleep aids and anti-anxiety drugs), diabetes medications, and narcotic pain relievers. All three categories have Moderate-severity interactions with bay leaf documented in our data.

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.

Bay leaf supplement may help with several conditions, but the evidence isn't strong enough yet to say whether it works. The bigger concern is that it interacts with sedatives, diabetes drugs, and narcotics — so if you're on any of those, check with us first.

Even if you're not on medications, the safety data for concentrated doses is thin, so this isn't a casual add-on.

Laurel (Bay) 450 mg by TerraVita Premium Collection: Common Questions

Does Laurel (Bay) 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Laurel (Bay) 450 mg 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 (Bay) 450 mg 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.
What is bay leaf, and what's it supposed to do?
Bay leaf — also called bay laurel — is the dried leaf of a plant traditionally used in cooking and folk medicine. In this product it's concentrated into a 450 mg capsule. The label suggests it may help with dandruff, diarrhea, menstrual cramps, and the common cold, but the scientific evidence for any of these uses isn't strong enough for us to rate it yet.
Can I take this if I'm on blood sugar medication?
Not without checking with your pharmacist or doctor first. Bay leaf can lower blood glucose, and combining it with diabetes medication raises your risk of dangerously low blood sugar (hypoglycemia). If you do take both, you'd need to monitor your glucose closely and your doctor may adjust your dose.
Is this safe to use long term?
Bay leaf used as a food seasoning is safe. But concentrated supplements like this one are less well studied over time. The safety data is thin for medicinal doses, so this isn't something to take indefinitely without talking to your pharmacist or doctor first.
Can I take this while pregnant or breastfeeding?
We don't have pregnancy or lactation safety data on file for this product. Talk with your pharmacist or doctor for personalized advice — they can help you weigh whether it's right for your situation.
What are the side effects?
In food amounts, bay leaf is well tolerated and rarely causes problems. At higher doses, allergic reactions and skin rash (contact dermatitis) can occur. The whole, unbroken leaf can cause choking or, very rarely, perforate your intestinal lining. Breathing in bay leaf powder may trigger asthma in some people.
