HelloPharmacist Scorecard of Holy Basil by plnt

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

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Holy Basil by plnt contains 2 active ingredients: organic holy basil and holy basil leaf powdered extract. Both are forms of the same herb and work the same way in your body.

The capsules also contain vegetable cellulose as an inactive ingredient.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Holy Basil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: adaptogen and antioxidant support.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Hypertension, Diabetes, Respiratory tract infections — and 2 related terms.
  • The closest evidence on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Generalized anxiety disorder (GAD) (Natural Medicines).
  • Also on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Diabetes, Hypertension, Insomnia, and more.

The evidence we hold doesn't establish that holy basil works for any of the conditions it's marketed for — generalized anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes all carry a rating of insufficient reliable evidence. That doesn't mean it doesn't work; it means the studies we have aren't strong enough to say either way.

If you're thinking about trying it for one of these reasons, talk it over with your doctor first.

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 short-term in adults, but we don't have solid long-term safety data. The most common side effects from oral use are loose stools and nausea — in one trial, 2 out of 24 people taking capsules experienced one of these.

The safety data advise against using it during pregnancy and while breastfeeding, since animal concerns exist and human safety isn't established.

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.

Double-check with your doctor or pharmacist before using this product if you take blood thinners (anticoagulants) or antiplatelet drugs, diabetes medications, or pentobarbital. All three carry Moderate interaction concerns with holy basil.

Altogether, these interactions span 212 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Holy Basil by plnt might be worth considering if you're interested in the herb and don't take blood thinners, diabetes medications, or pentobarbital — but the evidence for what it actually does is thin. If you're on any of those medications or have questions about whether it's right for you, check with your doctor or pharmacist before you start.

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

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 plnt: Common Questions

Does Holy Basil by plnt 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 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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?
No. Animal data raise concerns and human safety hasn't been established, so the safety information advises against holy basil during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about what's safe for you.
What are the most common side effects?
Loose stools and nausea are the most common, and they showed up in a small number of trial participants. Topically, holy basil mouthwash can leave a bitter taste. Most people tolerate it well short-term.
Does holy basil actually work for anxiety or diabetes?
The evidence isn't strong enough to say. All the conditions holy basil is marketed for — including anxiety and diabetes — have insufficient reliable evidence in the data we hold, so we can't confirm it works.
Is this safe to use long-term?
We don't have high-quality long-term safety data, so it's not clear. Short-term use in adults seems well tolerated, but if you're thinking about taking it regularly, talk with your doctor or pharmacist first.
Why do I need to check my diabetes or blood thinner medications?
Holy basil can lower blood sugar and may increase bleeding risk. If you're already on a drug that does either of those things, the combination could push you too far in that direction and cause problems.
