HelloPharmacist Scorecard of Holy Basil Leaves Powder 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 one active ingredient: Ocimum sanctum powder, commonly known as holy basil. There are no inactive fillers or other ingredients listed.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: supports healthy immunity and respiratory functions.
  • We looked for evidence on: Respiratory tract infections, immune function, upper respiratory health.
  • The closest evidence on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).

The evidence we hold on holy basil for its common uses — generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, and diabetes — is insufficient to establish how well it works. That doesn't mean it's ineffective; it means high-quality studies haven't yet proven it does or doesn't work for those purposes.

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 over the short term, but long-term safety data in humans are limited. The most common side effects from oral use are loose stools and nausea; a small number of trial participants in one study reported these.

Applied topically (like as a mouthwash), it can cause a bitter taste. The safety data advise against this product during pregnancy and while breastfeeding.

Animal research raised concerns, and reliable human safety information isn't available for either stage.

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 taking this product, check your medications against these types: blood thinners (anticoagulants and antiplatelets like warfarin and aspirin), diabetes drugs, and pentobarbital or other sedatives. These are the interactions we have data on; discuss your full medication list with your doctor or pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Holy basil may be worth considering if you're interested in its traditional uses, but the evidence for most claimed benefits isn't established yet. If you take blood thinners, diabetes medications, or pentobarbital, check with your doctor or pharmacist before starting — the interaction risks are real.
