HelloPharmacist Scorecard of Ocimum Sanctum 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.

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: Ocimum sanctum leaf extract powder, commonly known as holy basil. There are no other 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: anti-stress support.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Anxiety, Cortisol regulation.
  • 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 Insomnia, Stress.

The evidence we hold for holy basil doesn't support a clear effectiveness rating for any condition. The data show insufficient reliable evidence to rate it for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, or diabetes.

If you're considering this product for one of those uses, talk with your doctor or pharmacist about what the current evidence actually shows and whether it's the right choice for you.

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 in the short term in adults, but long-term safety data of high quality are limited. The most common side effects reported orally are loose stools and nausea — a small number of trial participants taking capsules experienced these.

When used topically in the mouth, it may cause a bitter taste. During pregnancy, holy basil is rated possibly unsafe, so the safety data advise against use.

While breastfeeding, there isn't enough reliable information — avoid it unless you've talked with your doctor or pharmacist. If you're pregnant, planning pregnancy, or breastfeeding, check with your own healthcare provider before taking this product.

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 taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin) — there's a moderate risk of increased bleeding. Also flag it if you're on diabetes medications, as holy basil may lower blood sugar further and raise the risk of low blood sugar.

If you take pentobarbital or other sedatives, run those by your pharmacist too, since holy basil may boost sedative effects.

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 generally well tolerated short-term, but if you take blood thinners, diabetes medications, or sedatives, you'll want to clear it with your doctor or pharmacist first because documented moderate-severity interactions exist. The evidence for its effectiveness on anxiety, asthma, headache, infections, or diabetes is not yet established.

Pregnant and breastfeeding individuals should avoid it unless directed otherwise by their healthcare provider.

Ocimum Sanctum Extract by Herbadiet: Common Questions

Does Ocimum Sanctum Extract by Herbadiet interact with any medications?
Yes. Based on its ingredients, Ocimum Sanctum 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?
Ocimum Sanctum 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.
What is Ocimum sanctum, and what is it used for?
Ocimum sanctum is commonly called holy basil. This product contains an extract of its leaves in powder form. The data we hold show insufficient evidence to rate it for anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes — so while people use it for these reasons, we don't have reliable evidence it works for them.
Can I take this if I'm pregnant or breastfeeding?
No — holy basil is rated possibly unsafe in pregnancy, so the safety data advise against it. While breastfeeding, there isn't enough reliable information to know either way, so avoid it as well. Talk with your doctor or pharmacist for personalized guidance.
What are the side effects?
Holy basil extract is generally well tolerated. The most common side effects when taken by mouth are loose stools and nausea — a small number of trial participants experienced these. If applied to the mouth (like in a mouthwash), it may cause a bitter taste.
Is there anything else in this powder besides holy basil?
No — this product contains only the active ingredient, Ocimum sanctum leaf extract powder, with no other inactive ingredients listed.
Can I take this with my blood thinner?
You'll need to check with your doctor or pharmacist first. Animal research suggests holy basil may increase bleeding risk when combined with blood thinners or antiplatelet drugs, though this hasn't been confirmed in humans. Don't add it without clearing it with your own healthcare provider.
Can I take this if I have diabetes?
Check with your doctor or pharmacist before use. Small studies show holy basil can lower blood sugar, so taking it with diabetes medications could theoretically increase the risk of low blood sugar. Your healthcare provider can advise whether it's right for you.
