HelloPharmacist Scorecard of Holy Basil by Paradise

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.

Paradise Holy Basil is a single-ingredient capsule: a whole spectrum extract of holy basil leaf. The capsule itself contains cellulose, an inactive filler.

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

This is a single-ingredient Holy Basil product and its label doesn't state a use — see Holy Basil's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we have for holy basil doesn't yet support its use for any condition. It's been studied for generalized anxiety, asthma, headache, respiratory infections, dental plaque, and diabetes, but in each case the data is too thin or weak to rate it effective.

If you're looking at this product for one of those reasons, the science isn't there yet to say it'll work.

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, though long-term safety data in humans are limited. The most common side effects reported are loose stools and nausea — a small number of trial participants in capsule form experienced one of these.

However, holy basil is rated possibly unsafe in pregnancy and should be avoided while breastfeeding, because animal data raise concerns and human safety hasn't been established. Talk with your doctor or pharmacist about whether it's right for you in those situations.

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.

Check with your doctor or pharmacist if you take blood thinners (anticoagulants or antiplatelets) — holy basil may increase bleeding risk. Also confirm you're clear if you take diabetes medications, since holy basil may lower blood sugar.

If you use pentobarbital (Nembutal) or other sedatives, let your healthcare provider know before starting this product.

Pentobarbital (Nembutal)

Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.

Holy Basil by Paradise: Common Questions

Does Holy Basil by Paradise 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 Paradise Holy Basil if I'm pregnant or breastfeeding?
No. Animal data raise safety concerns, so holy basil is rated possibly unsafe in pregnancy and should be avoided while breastfeeding. Talk with your doctor or pharmacist about what's safe for you during these times.
What side effects might I experience?
The most common are loose stools and nausea when taken by mouth. A bitter taste has been reported with topical holy basil mouthwash. Most people who've tried it tolerate it well, but long-term safety data in humans are limited.
Does holy basil actually work for anxiety or diabetes?
The evidence doesn't support it yet. We have insufficient data to rate holy basil effective for anxiety, diabetes, asthma, headache, respiratory infections, or dental plaque. If you're considering it for any of these, talk with your doctor about treatments with stronger evidence.
Is this product safe to use long-term?
Short-term use is generally well tolerated, but we don't have solid long-term safety data in humans. If you're thinking about taking it regularly, discuss that with your doctor or pharmacist.
What's in the capsule besides the holy basil extract?
Just cellulose, an inactive filler that holds the capsule together. No other active ingredients.
