HelloPharmacist Scorecard of Holy Basil by Bixa Botanical

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 Aug 6, 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 a single active ingredient: ocimum sanctum extract, commonly known as holy basil. It's delivered in an HPMC vegetarian capsule.

Holy basil is a plant native to South Asia, traditionally used in Ayurvedic medicine. The extract captures the plant's compounds in concentrated form.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: anti-infection agent.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for holy basil isn't yet strong enough to rate. The data we hold shows insufficient reliable evidence to say whether it works for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, or diabetes.

That doesn't mean it doesn't work — it means well-designed clinical trials haven't settled the question 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 by Bixa Botanical is generally well tolerated over the short term in adults. Long-term safety data are limited, though, so we don't have a full picture of what happens with extended use.

In clinical trials, a small number of people reported loose stools and nausea when taking it by mouth. The safety data advise against using holy basil during pregnancy or while breastfeeding, since animal data raise concerns and human safety isn't established.

Side effects, ingredient by ingredient Holy Basil

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, double-check with your doctor or pharmacist if you're on blood thinners (anticoagulants or antiplatelet drugs) — holy basil may increase bleeding risk. Also flag diabetes medications, since holy basil can lower blood sugar, and pentobarbital or other sedatives, since the product may amplify sedation.

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.

Holy Basil may appeal to you if you're interested in traditional herbal support, but the evidence for its effectiveness isn't yet clear. If you take blood thinners, diabetes medications, or sedatives like pentobarbital, you need to check with your doctor or pharmacist before adding this.

Talk it over with them before starting — they know your full medication list.

Holy Basil by Bixa Botanical: Common Questions

Does Holy Basil by Bixa Botanical interact with any medications?
Yes. Based on its ingredients, 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?
Holy Basil 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.
Can I take Holy Basil if I'm pregnant or breastfeeding?
The safety data advise against it in both cases. Animal research raises concerns, and human safety isn't established. Talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or breastfeeding.
What are the side effects?
Most people tolerate it well. In clinical trials, a small number experienced loose stools and nausea when taking it by mouth. If you use a mouthwash form, some people reported a bitter taste.
Does this actually work for anxiety, diabetes, or asthma?
We don't have enough solid evidence yet to say. The research to date is insufficient to rate its effectiveness for those conditions. If you're considering it for a specific health concern, talk with your doctor about whether a trial makes sense for you.
How long can I safely take this?
Short-term use in adults is generally well tolerated, but high-quality long-term safety data are limited. If you plan to take it regularly over months or longer, check in with your doctor or pharmacist first.
What exactly is in this capsule?
Each capsule holds ocimum sanctum extract — a concentrated form of holy basil — inside an HPMC vegetarian capsule. That's it.
