HelloPharmacist Scorecard of Tulsi - Holy Basil by Organic India

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product has 3 active ingredients—holy basil and East Indian basil (which are the same plant, listed under different names) plus pullulan, an inactive capsule material. Holy basil is a traditional herb from India, also called tulsi, and it's the whole active component in this formula.

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: Daily cognitive support and stress relief.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Headache, Mental clarity, Cognitive function — and 2 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 Headache, Insomnia, Stress.

The evidence for what holy basil actually does isn't established yet in the data we hold. Studies haven't given us reliable proof that it works for generalized anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes—even though people have used it for centuries.

That doesn't mean it doesn't work; it means the evidence just isn't there yet.

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 seems to be well tolerated short-term in adults, but we don't have good long-term safety data. The most common side effects in a small trial were loose stools and nausea—a small number of trial participants experienced these.

You should avoid this supplement during pregnancy and while breastfeeding; animal data raise concerns, and human safety information isn't established for either situation.

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.

Check with your pharmacist before taking this if you're on blood thinners or antiplatelet drugs (like warfarin, apixaban, or aspirin), diabetes medications, or pentobarbital or other barbiturate sedatives. Moderate interactions are documented for all three categories.

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.

Tulsi by Organic India could work for you if you're exploring traditional herbal support, but the evidence for specific uses isn't solid yet. If you take blood thinners, diabetes medications, or any sedatives, check with us first—this one needs a closer look.

Talk to your pharmacist before starting, especially if you're on prescription medications.

Tulsi - Holy Basil by Organic India: Common Questions

Does Tulsi - Holy Basil by Organic India interact with any medications?
Yes. Based on its ingredients, Tulsi - Holy Basil 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?
Tulsi - Holy Basil contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 if I'm pregnant or breastfeeding?
No. The safety data advises against using holy basil during pregnancy and while breastfeeding. Animal data raise concerns, and human safety hasn't been established. Talk to your doctor about what's safe for you.
What are the most common side effects?
Loose stools and nausea are the main ones reported. In one clinical trial, a small number of people taking holy basil capsules experienced these. Overall, it seems well tolerated, but long-term safety data are limited.
Does this actually work for anxiety or diabetes?
The evidence isn't established in our data. We don't have reliable proof that holy basil works for anxiety, diabetes, or the other uses people claim. That doesn't mean it doesn't—just that the science isn't there yet.
Why does this supplement interact with so many medications?
Holy basil's compounds can affect how your body processes blood sugar and clotting, and may enhance sedation. These are broad effects, so they touch several medication categories. That's why checking your specific drugs is important.
Is it safe to take this long-term?
We don't have good data on long-term safety. It's generally well tolerated short-term in adults, but high-quality studies over months or years are missing. If you're thinking long-term use, ask your pharmacist about what we know and don't know.
