HelloPharmacist Scorecard of Holy Basil by Oregon's Wild Harvest

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 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: holy basil. That's it for actives.

The only other ingredient listed is pullulan, which is an inactive ingredient (a binder used to make the capsule). So you're getting holy basil extract in capsule form with minimal added ingredients.

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 data we hold shows insufficient reliable evidence to rate holy basil for any of the conditions it's traditionally used for—generalized anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes. That doesn't mean it doesn't work; it means the evidence available isn't solid enough to establish whether it does.

If you're considering it for one of these reasons, talk with your pharmacist about what the research actually shows.

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 is generally well tolerated in the short term, though 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 people in clinical trials experienced these.

During pregnancy, the safety data advises against it; animal studies raise concerns and human safety is not established. While breastfeeding, there isn't enough reliable safety information, so it's best to avoid it then too.

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 start this product, double-check with your pharmacist if you take blood thinners or antiplatelet drugs—there's a moderate risk of increased bleeding. Also flag it if you're on diabetes medications (moderate risk of blood sugar dropping too low) or pentobarbital (moderate risk of increased drowsiness).

These are the medication types documented to interact with holy basil.

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 from Oregon's Wild Harvest may be worth considering if you're interested in its traditional uses, but the evidence for effectiveness isn't established yet. If you take blood thinners, diabetes medications, or pentobarbital, check with your pharmacist first—those are the interactions that matter most.

And skip it if you're pregnant or breastfeeding.

Anticoagulant/Antiplatelet Drugs

Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Small clinical studies show that taking holy basil can decrease fasting blood glucose and other measures of glycemic control in patients with type 2 diabetes.

Likelihood Possible Evidence B
Pentobarbital (Nembutal)

Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.
Animal research shows that holy basil seed oil increases pentobarbitone-induced sleeping time. However, it is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Holy Basil by Oregon's Wild Harvest: Common Questions

Does Holy Basil by Oregon's Wild Harvest 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.
What actually is holy basil, and is it the same as the basil in cooking?
Holy basil is a plant extract used in supplements, and no—it's different from the culinary basil you cook with. This product gives you holy basil in capsule form.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against it in pregnancy because animal studies raised concerns and human safety isn't established. While breastfeeding, there isn't enough reliable safety information either. Talk with your doctor or pharmacist about what's right for your situation.
What side effects should I expect?
Most people tolerate it well. The most common side effects from capsules are loose stools and nausea, though only a small number of people in studies experienced these. It's generally well tolerated short-term, but long-term safety data in humans are limited.
Does holy basil actually work for anxiety or diabetes?
The evidence we hold is insufficient to say whether it works for anxiety, diabetes, asthma, headache, infections, or dental plaque. That doesn't mean it doesn't—just that the research available isn't solid enough to establish it.
Is there anything else in these capsules besides holy basil?
Each capsule contains holy basil extract plus pullulan, which is an inactive ingredient that helps form the capsule. No fillers or unnecessary extras beyond that.
