HelloPharmacist Scorecard of Coleus Forskohlii by Herbadiet

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.

This product contains 2 active ingredients: Coleus forskohlii Root Extract and Coleus Forskohlii. Both are forms of the same plant.

The main active compound in coleus is called forskolin, which is what the research focuses on. The capsule itself is made from vegetable cellulose, which is an inactive filler.

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 Coleus's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: boosts libido, testosterone, and sexual wellness.
  • We looked for evidence on: Erectile dysfunction (ED), testosterone support, sexual function, blood flow.
  • The closest evidence on file: Coleus is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED) (Natural Medicines).

The effectiveness of coleus forskohlii hasn't been reliably established. The data we hold rates all its studied uses — including angina (chest pain), asthma, cancer, congestive heart failure, eczema, and dry eye — as having insufficient reliable evidence to rate.

That means the studies aren't strong enough yet to say whether it works or not.

The evidence, ingredient by ingredient Coleus

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.

When taken by mouth, coleus is generally well tolerated, but gastrointestinal side effects are the main concern. About 1 in 15 trial participants experienced loose stools or increased bowel movements, and retrospective reports suggest roughly a 10% rate of digestive upset overall — mostly diarrhea.

Nausea, vomiting, and constipation occur at lower rates. The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.

Coleus may lower blood pressure and isn't well studied for long-term use, so use it only with care and professional guidance.

Side effects, ingredient by ingredient Coleus

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Coleus.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 916 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 this supplement against any nitrates or calcium channel blockers you take — those are Major severity concerns. Also flag it if you're on blood pressure medications, blood thinners, antiplatelet drugs, or warfarin.

And mention it if you take medications broken down by CYP2C9 or CYP3A4 enzymes, since coleus may change how your liver handles them.

The bottom line

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

Coleus forskohlii is one you'll want to clear with us before you start, especially if you take heart drugs, blood pressure medications, or blood thinners. The evidence for what it actually does isn't established yet.

If digestive side effects are a concern for you, keep that in mind. Talk to your pharmacist before adding this to your routine.

Coleus forskohlii Root Extract7 drug types · 915 drugs

Calcium Channel Blockers

Theoretically, combining coleus with calcium channel blockers might increase the coronary vasodilatory effects.
Forskolin, a constituent of coleus, and calcium channel blockers both cause coronary vasodilatory effects.

Likelihood Probable Evidence B
Nitrates

Theoretically, combining coleus with nitrates might increase the coronary vasodilatory effects.
Forskolin, a constituent of coleus, and nitrates both cause coronary vasodilatory effects.

Likelihood Probable Evidence B
Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of coleus and anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro and animal research shows that forskolin, a constituent of coleus, can inhibit platelet aggregation and adhesion.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, combining coleus with antihypertensive drugs might cause additive blood pressure lowering effects and increase the risk of hypotension.
Animal research shows that forskolin, a constituent of coleus, may lower blood pressure.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, taking coleus may affect drugs metabolized by CYP2C9 and increase the risk of adverse effects or reduce the effectiveness.
Research on the effect of coleus on CYP2C9 is conflicting. Some animal research shows that coleus extract can induce CYP2C9, while in vitro research shows that coleus can inhibit CYP2C9. Until more is known, advise patients that taking coleus might increase or decrease levels of drugs metabolized by CYP2C9.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, taking coleus might decrease serum levels of drugs metabolized by CYP3A4.
In vitro research shows that coleus can activate the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of coleus and other drugs affected by these enzymes.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, taking coleus may affect the metabolism of warfarin and increase the risk of adverse effects or reduce the effectiveness.
Some animal research shows that coleus extract can induce cytochrome P450 2C9 (CYP2C9), an enzyme that metabolizes warfarin. However, other in vitro research shows that coleus can inhibit CYP2C9. Theoretically, taking coleus with drugs metabolized by CYP2C9 might affect drug levels and the risk of adverse effects. Until more is known, advise patients that taking coleus might increase or decrease levels of warfarin.

Coleus Forskohlii by Herbadiet: Common Questions

Does Coleus Forskohlii by Herbadiet interact with any medications?
Yes. Based on its ingredients, Coleus Forskohlii has a known interaction with 915 medications, including 29 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Coleus Forskohlii 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?
Not according to the safety data. There isn't enough information to know it's safe during pregnancy or while breastfeeding, so the data advises against both. Talk with your doctor or pharmacist for personalized advice based on your situation.
What are the most common side effects?
Loose stools and diarrhea are the most frequent — one trial participant out of 15 experienced increased bowel movements. Nausea, vomiting, and constipation also occur, but less often. Gastrointestinal upset is dose-related, meaning higher doses are more likely to cause it.
Does this product actually work for anything?
We don't have strong enough evidence to say yet. The conditions it's been studied for — angina, asthma, cancer, heart failure, eczema, and dry eye — all lack reliable evidence to confirm whether it works.
Is this safe to take long-term?
It's not well studied for long-term use. The data also notes it may lower blood pressure, so if you're using it, do so only with care and professional guidance — talk to your pharmacist or doctor about how long is safe for you.
What's the active ingredient in this product?
The main active compound is called forskolin, which comes from the coleus plant root. Both ingredients listed on this product are forms of the same plant.
