HelloPharmacist Scorecard of Holy Basil Extract by Herbadiet

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 capsule contains one active ingredient: holy basil extract. There are no inactive ingredients listed.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Holy Basil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: stress resilience, immunity, strength and calm clarity.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Respiratory tract infections, Anxiety, Sleep quality — and 1 related terms.
  • The closest evidence on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Generalized anxiety disorder (GAD) (Natural Medicines).
  • Also on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Insomnia, Stress.

The evidence for holy basil isn't established yet for the conditions studied. Our data shows insufficient reliable evidence to rate it for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, or diabetes.

That doesn't mean it doesn't work—it means the clinical trials so far haven't been strong enough to say one way or the other.

The evidence, ingredient by ingredient Holy Basil

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.

Holy Basil Extract is generally well tolerated short-term in adults, but we don't have strong long-term safety data. The most common side effects from oral use are loose stools and nausea—a small number of trial participants reported these.

The safety data advises against it during pregnancy and while breastfeeding, so talk with your doctor or pharmacist before taking it if you're pregnant, planning to be, or nursing.

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 — Holy Basil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 212 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 you take this product, double-check it with your doctor or pharmacist if you're on any blood thinners (anticoagulants or antiplatelet drugs) or diabetes medications—both are Moderate-severity interactions. Also mention it if you take pentobarbital or other sedatives.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Herbadiet's Holy Basil Extract is a single-ingredient supplement generally well tolerated short-term, but its effectiveness for the conditions it's marketed for isn't yet proven. If you take blood thinners, diabetes medications, or sedatives, you'll want to check with your doctor or pharmacist before starting it—the interactions are documented but mostly from animal research, so your personal risk depends on your exact medications and doses.

During pregnancy or breastfeeding, the safety data advises against it.

Holy Basil Extract by Herbadiet: Common Questions

Does Holy Basil Extract by Herbadiet interact with any medications?
Yes. Based on its ingredients, Holy Basil Extract has a known interaction with 212 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Holy Basil 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.
Will this help my anxiety or blood sugar?
We don't have strong enough evidence yet to say. Clinical trials have been too small or limited to prove holy basil works for generalized anxiety, diabetes, or the other conditions on the label. Some small studies do suggest it might lower blood sugar in type 2 diabetes patients—which is actually why it's a concern if you're already on diabetes drugs—but we'd need bigger, better-designed trials to be sure.
What are the most common side effects?
Loose stools and nausea are the main ones reported from oral use. A small number of trial participants experienced these. If you use it topically as a mouthwash, a bitter taste has been reported.
Can I take this while I'm pregnant or breastfeeding?
The safety data advises against it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist before using it if you're in either situation—they can discuss your individual needs.
Is this safe to take long-term?
Short-term use in adults appears well tolerated, but we don't have good quality long-term safety data, so that's worth discussing with your doctor or pharmacist if you're thinking of using it regularly.
What exactly is in one capsule?
Just holy basil extract. There are no other active ingredients or fillers listed.
