HelloPharmacist Scorecard of Core Convallaria Blend by Energetix
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
Low disclosure
Core Convallaria Blend contains five active herbal ingredients. The main ones are arjuna (terminalia), lily-of-the-valley (convallaria — the plant the product is named after), cactus (cereus), khella, and linden.
The liquid also contains ethanol and purified water as inactive ingredients. Lily-of-the-valley is the ingredient that gives this product its name, but it's also the most dangerous one because it holds cardiac glycosides — compounds your heart is very sensitive to.
The other herbs are traditionally used for heart and circulatory support, though the evidence for how well they actually work is not established in the data we hold.
Does it work?
Couldn't assess
The evidence we have doesn't establish that any of these ingredients work reliably for their intended uses. Arjuna is listed for obesity, high cholesterol, high blood pressure, and angina, but all those ratings are insufficient evidence to rate.
Lily-of-the-valley and cactus show insufficient evidence for arrhythmia and heart failure. Khella shows insufficient evidence for psoriasis and vitiligo.
Linden has no effectiveness ratings on file. If you're considering this product for a specific condition, talk to your pharmacist or doctor about what the actual science supports.
How safe is it?
Well-documented data
Lily-of-the-valley is unsafe to take by mouth without medical supervision — it's poisonous and can cause life-threatening heart problems including abnormal heart rhythms, headache, and visual disturbances. The safety data advises against it during pregnancy and breastfeeding.
Arjuna is generally well tolerated short-term in studies, but long-term safety varies widely by product. Cactus, khella, and linden all have limited safety information.
Cactus may cause mouth burning, nausea, vomiting, and diarrhea. Khella can cause nausea, dizziness, constipation, loss of appetite, headache, itching, insomnia, and (in some cases) raised liver enzymes and sun sensitivity.
Linden is generally well tolerated as a tea but has limited human safety data; one case of allergic reaction to linden pollen in tea has been reported.
Meds to double-check
Major interaction found
Before taking this product, check with your pharmacist or doctor if you take digoxin or any heart medication, corticosteroids, blood thinners or antiplatelet drugs, diabetes medications, any drug your liver metabolizes (nearly all common medications), lithium, or any drug that causes sun sensitivity. No interactions are documented for the inactive ingredients.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product contains lily-of-the-valley, a toxic plant that can cause serious heart problems — this alone makes it risky. The other four ingredients interact with a very large number of medications and affect how your liver clears drugs and how your heart works.
If you take any prescription or over-the-counter medication, do not start this product without checking every single drug against the interaction tool on this page and talking with your pharmacist or doctor.

Core Convallaria Blend by Energetix Drug Interactions
HelloPharmacist Interaction Report
Core Convallaria Blend by Energetix contains five active herbal ingredients, and they interact with a substantial number of medications.
The most serious concern is lily-of-the-valley, which carries Major-severity interactions with digoxin (a heart medication), prolonged corticosteroid use, and quinine — all because lily-of-the-valley contains cardiac glycosides (plant compounds that affect the heart). Even small amounts can cause dangerous heart rhythm problems or toxicity.
Read the full breakdown — every affected drug type, severity by severity
Arjuna moderately interacts with several categories: it can boost blood levels of drugs that your liver breaks down via the CYP2D6, CYP2C9, and CYP3A4 pathways (a large group including many common medications); it may raise bleeding risk with blood thinners and antiplatelet drugs; and it might lower blood sugar unpredictably with diabetes medications. Cactus, khella, and linden each have their own moderate interactions — cactus with heart medications and certain antidepressants, khella with digoxin, sun-sensitizing drugs, and liver-toxic medications, and linden with lithium.
Altogether, these interactions span 1,271 individual medications. Because this product contains lily-of-the-valley — a genuinely toxic plant — we strongly recommend you check every medication you take with the search tool below before starting.

For each ingredient in Core Convallaria Blend with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Arjuna
Anticoagulant/Antiplatelet Drugs
Theoretically, concomitant use of Terminalia arjuna with anticoagulant or antiplatelet drugs may increase the risk of bleeding in some patients.
In vitro, Terminalia arjuna bark extract inhibits platelet aggregation, decreases platelet activation, and shows antithrombotic properties.
Antidiabetes Drugs
Theoretically, concomitant use of Terminalia bellirica or Terminalia chebula with antidiabetes drugs could affect blood sugar control and increase the risk of hypoglycemia.
Animal and in vitro research shows that Terminalia bellirica and Terminalia chebula fruit and seed extract have hypoglycemic effects.
Chlorzoxazone (Parafon Forte, Paraflex)
Theoretically, use of Terminalia chebula may increase the risk of adverse effects from chlorzoxazone.
Animal research shows that enteral administration of Terminalia chebula for 15 days prior to administration of chlorzoxazone increases blood levels of chlorzoxazone and decreases chlorzoxazone clearance. It is speculated that Terminalia chebula reduces the metabolism of chlorzoxazone by inhibiting cytochrome P450 2E1.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP2C9 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP2C9 enzymes and reduces CYP2C9 substrate metabolism.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP2D6 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP2D6 enzymes and reduces CYP2D6 substrate metabolism.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP3A4 enzymes and reduces CYP3A4 substrate metabolism.
Omeprazole (Prilosec)
Theoretically, use of Terminalia chebula may increase the risk of adverse effects from omeprazole.
Animal research shows that enteral administration of Terminalia chebula for 15 days prior to administration of omeprazole increases blood levels of omeprazole and decreases omeprazole clearance. It is speculated that Terminalia chebula reduces the metabolism of omeprazole by inhibiting cytochrome P450 2C19.
Khella
Digoxin (Lanoxin)
Theoretically, khella might decrease the effectiveness of cardiac glycosides like digoxin. The khella constituent visnadin has negative inotropic effects that might counter the effects of cardiac glycosides.
Hepatotoxic Drugs
Theoretically, khella might have additive adverse effects on the liver when used with hepatotoxic drugs. Khella can increase liver transaminases. Some drugs that can adversely affect the liver include acetaminophen (Tylenol), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), and many others.
Photosensitizing Drugs
Theoretically, concomitant use might result in increased photosensitivity. Khella constituents can cause photosensitivity. Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.
Lily of the Valley
Corticosteroids
Theoretically, using lily-of-the-valley with prolonged corticosteroid therapy can cause cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. Concomitant, long-term corticosteroid use can increase the risk of cardiac glycoside toxicity due to potassium depletion and electrolyte imbalance.
Digoxin (Lanoxin)
Using lily-of-the-valley with digoxin can cause cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. Use of the cardiac glycoside digoxin and lily-of-the-valley concomitantly increases the risk of cardiac glycoside toxicity.
Quinine
Theoretically, using lily-of-the-valley with quinine can increase the risk of cardiac glycoside toxicity.
Quinine may reduce the clearance of oral digoxin. Theoretically, concomitant use of quinine with lily-of-the-valley might reduce the clearance of cardiac glycosides found in lily-of-the-valley and increase the risk of toxicity.
Diuretic Drugs
Theoretically, using lily-of-the-valley with diuretics can increase the risk of cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. Concomitant use of potassium depleting diuretics and lily-of-the-valley can increase the risk of cardiac glycoside toxicity due to potassium depletion and electrolyte imbalance.
Lithium
Theoretically, lily-of-the-valley can increase levels of lithium and increase toxicity.
Lily-of-the-valley is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, lily-of-the-valley might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
Macrolide Antibiotics
Theoretically, using lily-of-the-valley with macrolide antibiotics can increase the risk of cardiac glycoside toxicity.
Macrolide antibiotics appear to increase the gastrointestinal absorption of oral digoxin. Theoretically, concomitant use of macrolide antibiotics might increase the absorption of the cardiac glycosides found in lily-of-the-valley.
Stimulant Laxatives
Theoretically, using lily-of-the-valley with stimulant laxatives can increase the risk of cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. The overuse of stimulant laxatives can increase the risk of cardiac glycoside toxicity with lily-of-the-valley due to potassium depletion.
Tetracycline Antibiotics
Theoretically, using lily-of-the-valley with tetracycline antibiotics might increase the risk of cardiac glycoside toxicity.
Tetracycline antibiotics appear to increase the gastrointestinal absorption of oral digoxin, a cardiac glycoside. Theoretically, concomitant use of tetracycline antibiotics might increase the absorption of the cardiac glycosides found in lily-of-the-valley.
Cactus
Digoxin (Lanoxin)
Cereus may potentiate the actions of cardiac glycosides and may enhance the effect of other cardiac drugs.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, excessive doses of cereus may interact with MAOIs, because of the tyramine content.
Linden
Lithium
Theoretically, due to its potential diuretic effects, linden might increase the effects and adverse effects of lithium.
Linden is thought to have diuretic properties. The dose of lithium might need to be decreased.
