HelloPharmacist Scorecard of Ocimum Spp. Holy Basil by Wise Woman Herbals

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 27, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

This product contains one active ingredient: holy basil, delivered in liquid form. Holy basil is an herb used traditionally in Ayurvedic medicine.

The liquid also includes alcohol and spring water as inactive 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 evidence we hold doesn't establish that holy basil works reliably for any of its common uses. Studies are too small or limited to rate its effectiveness for generalized anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes.

That doesn't mean it doesn't work — it means the data we have aren't strong enough yet to be sure.

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 in the short term, but long-term safety data in humans are limited. The most common side effects when taken by mouth are loose stools and nausea — a small number of trial participants reported these.

Applied topically (like mouthwash), it may cause a bitter taste. The safety data advise against use during pregnancy and while breastfeeding, since animal research raises concerns and human safety isn't established.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or nursing.

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 product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin), diabetes medications, or the sedative pentobarbital — these carry Moderate interactions with holy basil. No other interactions are documented for the ingredient we checked.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable 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 traditional herbal support and you don't take blood thinners, diabetes medications, or pentobarbital — but the evidence for what it actually does is still unclear. If you're on any medications, check them against the interaction tool before starting.

Talk with your doctor or pharmacist about whether this product makes sense for your situation.

Ocimum Spp. Holy Basil by Wise Woman Herbals: Common Questions

Does Ocimum Spp. Holy Basil by Wise Woman Herbals interact with any medications?
Yes. Based on its ingredients, Ocimum Spp. 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?
Ocimum Spp. 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 this if I'm pregnant or breastfeeding?
The safety data advise against it. Animal research raises concerns and human safety isn't established for either pregnancy or breastfeeding. Talk with your doctor or pharmacist for personalized advice.
What are the side effects?
Holy basil extract is generally well tolerated. The most common side effects when taken by mouth are loose stools and nausea, reported by a small number of trial participants. If applied as a mouthwash, it may cause a bitter taste.
Does this actually work for anxiety, diabetes, or asthma?
We don't have enough reliable evidence to say. The studies are too small or limited to establish whether holy basil works reliably for these uses or others listed on the label.
Why do I need to check my blood sugar medications?
Small clinical trials show holy basil can lower fasting blood glucose. If you take a diabetes drug that already lowers blood sugar, combining them might push your level too low. Your doctor or pharmacist can help you decide if it's safe for you.
Is this safe with blood thinners like warfarin?
Animal studies show holy basil seed oil may prolong bleeding time, so it carries a Moderate interaction with blood thinners and antiplatelet drugs. We don't know for certain if this happens in people, but your doctor or pharmacist should review this before you start.
