HelloPharmacist Scorecard of Coleus 10:1 Extract Powder by TerraVita Premium Collection
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 one active ingredient: Coleus Extract in a 10:1 powder form. Coleus is a plant extract containing an active compound called forskolin, which is the main driver behind the supplement's proposed effects on the body.
There are no inactive ingredients listed for this product.
Does it work?
Couldn't assess
The evidence isn't established in the data we hold for any of coleus's proposed uses. The supplement has been studied for angina (chest pain), asthma, cancer, congestive heart failure, atopic dermatitis (eczema), and dry eye — but in each case we don't have reliable evidence yet to say whether it works.
If you're considering this product for any specific condition, that's a conversation worth having with your doctor or pharmacist.
How safe is it?
Well-documented data
Coleus seems to be well tolerated when taken by mouth, though it can cause gastrointestinal side effects. The most common are constipation, diarrhea, nausea, and vomiting — diarrhea in particular has been reported in a small number of trial participants and in retrospective reports at roughly a 10% rate.
Because coleus may lower blood pressure and isn't well studied for long-term use, it calls for caution and professional guidance. The safety data advises against use during pregnancy and while breastfeeding — there simply isn't enough data to know either way, so talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or nursing.
Meds to double-check
Major interaction found
Before taking this product, check with your pharmacist if you take nitrates or calcium channel blockers for chest pain or heart conditions (Major severity risk), blood pressure medications, blood thinners like warfarin or aspirin, or any drug your liver metabolizes through the CYP2C9 or CYP3A4 pathways (all Moderate severity). Your liver's metabolism of the medication may change in unpredictable ways.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Coleus may be worth exploring if you're researching natural approaches to certain conditions, but it's not a product to start on your own, especially if you take heart, blood pressure, or blood-thinning medications. The interaction profile is complex and affects hundreds of drugs.
Talk with your pharmacist before adding this to your routine.

HelloPharmacist Interaction Report
Coleus 10:1 Extract Powder from TerraVita Premium Collection does interact with several medication types, and the most serious concerns are with heart medications.
The active compound in coleus, called forskolin, can strengthen the effects of nitrates and calcium channel blockers (both used for chest pain and heart conditions), which theoretically could lower your blood pressure or increase coronary blood flow beyond what's intended. This is rated a Major interaction severity.
Read the full breakdown — every affected drug type, severity by severity
Beyond heart drugs, coleus may also interact with blood pressure medications (increasing the risk of blood pressure dropping too low), blood thinners and antiplatelet drugs like aspirin or warfarin (raising bleeding and bruising risk), and certain drugs your liver processes through the CYP2C9 and CYP3A4 pathways. These are Moderate severity concerns.
The interaction with coleus and warfarin is especially tricky because the research is conflicting — some evidence suggests coleus speeds up warfarin metabolism while other evidence suggests it slows it down, making the effect unpredictable.
Coleus also appears to affect how your liver metabolizes a broad range of medications. Altogether, these interactions span 904 individual medications.
If you take any prescription medication — particularly for your heart, blood pressure, or blood clotting — use the interaction checker below with your exact drug names before starting this product.

For each ingredient in Coleus 10:1 Extract Powder with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Coleus Extract, Powder
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.
