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.
What’s inside
Full disclosure
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
Major interaction found
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 by Herbadiet Drug Interactions
HelloPharmacist Interaction Report
Coleus Forskohlii by Herbadiet interacts with several medication types, and the most serious concerns are with heart drugs.
Combining coleus with nitrates (used for chest pain) or calcium channel blockers (heart and blood pressure medications) could theoretically increase their effects too much, which carries Major severity risk. Both coleus and these drugs widen blood vessels in the heart, and doing both at once might be too much.
Read the full breakdown — every affected drug type, severity by severity
Coleus also interacts with blood pressure medications (antihypertensive drugs), blood thinners (anticoagulants and antiplatelet drugs), and warfarin specifically — all Moderate severity. It may lower blood pressure further on top of what these drugs already do, or increase bruising and bleeding.
Coleus can also affect how your liver breaks down certain medications metabolized by CYP2C9 and CYP3A4 enzymes, which might make some drugs less effective or cause them to build up.
Altogether, these interactions span 916 individual medications. Before you start this supplement, run your exact medications through the checker below — especially if you take any heart or blood pressure drugs, blood thinners, or warfarin.

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