HelloPharmacist Scorecard of BioDynamic Organic Tulsi Holy Basil by Dr. Mercola

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 16, 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 3 active ingredients.
  • “Tulsi Holy Basil Blend” is a proprietary blend — the label gives one combined amount (1 Gram(s)) without saying how much of each component you get.

This product contains three active ingredients—two varieties of Holy Basil powder (Rama and Krishna) and one variety of plain Basil powder (Vana)—all organic. The blend is designed to deliver the traditional benefits of tulsi, an herb used in Ayurvedic medicine.

The tablet also includes gum acacia as an inactive ingredient to hold it together.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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

The evidence for what this product actually does isn't established in our data. Both Holy Basil varieties carry ratings of insufficient evidence for generalized anxiety, asthma, headaches, respiratory infections, dental plaque, and diabetes.

The Vana Tulsi variety shows the same gap for acne, headaches, colds, constipation, diarrhea, and gas. That doesn't mean it doesn't work—it means the high-quality studies we'd need to say for sure haven't been done or aren't in our files.

The evidence, ingredient by ingredient Holy Basil 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Short-term, this product is generally well tolerated in adults, though long-term safety data are limited. The most common side effects from oral holy basil in trials are loose stools and nausea—a small number of trial participants experienced these.

One case of allergic contact dermatitis was reported with occupational basil exposure, so if you have sensitive skin, keep that in mind. Don't take this during pregnancy or while breastfeeding.

The safety data advise against it for both—animal studies raise concerns about the holy basil components, and there isn't enough reliable human safety information for any of them in these settings. Talk with your doctor or pharmacist if you're pregnant, planning to be, or nursing.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Basil, Holy Basil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 379 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 before you take this if you're on blood thinners or antiplatelet drugs, diabetes medications, blood pressure medications, or pentobarbital or other sedatives. These are the medication types documented to interact with the tulsi varieties in this product.

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.

This product is generally well tolerated short-term, but it interacts with blood thinners, diabetes drugs, blood pressure medications, and sedatives—and the evidence for what it's supposed to do isn't established. If you take any of those medication types, or if you're pregnant or breastfeeding, talk with your doctor or pharmacist before you start it.

BioDynamic Organic Tulsi Holy Basil by Dr. Mercola: Common Questions

Does BioDynamic Organic Tulsi Holy Basil by Dr. Mercola interact with any medications?
Yes. Based on its ingredients, BioDynamic Organic Tulsi Holy Basil has a known interaction with 379 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
BioDynamic Organic Tulsi Holy Basil contains 3 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 on a blood thinner like warfarin?
Not without checking with your doctor or pharmacist first. This product may increase the risk of bleeding when combined with blood thinners or antiplatelet drugs. Your healthcare provider can advise whether it's safe for you or if you need monitoring.
Will this lower my blood sugar if I take diabetes medication?
It might. Small studies show holy basil can lower blood sugar, so combining it with diabetes drugs could raise your risk of low blood sugar (hypoglycemia). Talk to your doctor or pharmacist before adding it to your routine.
Is this safe to take while pregnant?
No. The safety data advise against it during pregnancy. Animal studies raise concerns about the holy basil components, and human safety isn't established. If you're pregnant or planning to be, talk with your doctor or pharmacist.
What are the common side effects?
Loose stools and nausea are the most commonly reported. In one trial, a small number of participants taking holy basil capsules experienced these. Most people tolerate it well in the short term.
Can I use this for anxiety or diabetes?
The evidence isn't there yet to say this works for either. Both holy basil varieties show insufficient reliable evidence for generalized anxiety and diabetes. That means high-quality studies proving it works haven't been done or aren't on file.
Is this safe while breastfeeding?
No. There isn't enough reliable safety information, so the data advise against it while breastfeeding. If you're nursing, talk with your doctor or pharmacist before you take it.
