HelloPharmacist Scorecard of HT Combination by Pure Herbs
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
HT Combination contains 3 active ingredients: motherwort extract, myrrh gum, and hawthorn. These are blended together in capsule form with gelatin as the capsule material.
Motherwort has traditionally been used in herbal practice for bleeding and various conditions. Myrrh gum is a resin traditionally used for several purposes.
Hawthorn, derived from the hawthorn plant, has a long history in herbal medicine, particularly for heart and circulation support.
Does it work?
Moderate evidence
The evidence for these ingredients is limited. Motherwort shows possibly effective evidence for bleeding; for other uses in this product (anxiety, alcohol use disorder, amenorrhea, asthma), the evidence is insufficient to rate.
Myrrh gum shows likely ineffective evidence for schistosomiasis; for other conditions (back pain, cancer, common cold, dental issues, Crohn disease), evidence is insufficient to rate. Hawthorn has insufficient evidence to rate for angina, anxiety, heart rhythm problems, atherosclerosis, cardiovascular disease, and cognitive function.
In short, we hold no established effectiveness data for the specific uses this product is intended to address.
How safe is it?
Well-documented data
Motherwort is generally well tolerated by healthy adults when used short-term, though human safety data are limited. The most common oral side effects are diarrhea and stomach irritation; in amounts greater than 3 grams, it may cause uterine bleeding.
Motherwort is traditionally thought to stimulate the uterus and should be avoided in pregnancy. Myrrh is likely fine for short-term topical use or mouth rinses, but oral safety is not well studied.
Oral doses of 2–4 grams may cause diarrhea; it too should be avoided in pregnancy. Hawthorn is generally well tolerated in studies, though it needs medical supervision if you have a heart condition.
Rarely, it has caused acute kidney failure. Hawthorn should be avoided in pregnancy and breastfeeding due to insufficient safety information.
All three ingredients have been associated with contact dermatitis when applied to skin.
Meds to double-check
Major interaction found
Before taking this product, check with your doctor or pharmacist if you take nitrates or phosphodiesterase-5 inhibitors (Major risk); beta-blockers, calcium channel blockers, anticoagulants or antiplatelet drugs, or digoxin (Moderate risk); diabetes medications or warfarin (Moderate risk); or any central nervous system depressants like sedating medications (Moderate risk).
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
This product combines three herbal extracts with limited evidence for their intended uses and serious potential interactions—especially with heart, blood pressure, and blood-thinning medications. If you take any medication for your heart, circulation, or blood clotting, or any sedating drugs, talk to your doctor or pharmacist before starting HT Combination.
The same goes if you're pregnant, breastfeeding, or planning to become pregnant.

HT Combination by Pure Herbs Drug Interactions
HelloPharmacist Interaction Report
HT Combination by Pure Herbs interacts with medications through its hawthorn, motherwort, and myrrh gum content.
The most serious interactions are Major in severity: hawthorn with nitrates (drugs like nitroglycerin used for chest pain) and phosphodiesterase-5 inhibitors (such as sildenafil/Viagra), both of which may cause dangerous drops in blood pressure when combined.
Read the full breakdown — every affected drug type, severity by severity
Hawthorn also carries Moderate interactions with blood pressure and heart medications—beta-blockers, calcium channel blockers—and with blood thinners (anticoagulants and antiplatelet drugs), where bleeding risk may increase. It may also affect digoxin (a heart medication), potentially raising its effects and side effects.
Motherwort adds a Moderate interaction with central nervous system depressants (sedating medications), which could increase drowsiness. Myrrh gum presents Moderate interactions with diabetes medications (a risk of low blood sugar) and warfarin (a blood thinner), where myrrh may reduce warfarin's effectiveness.
Altogether, these interactions span 506 individual medications. You'll want to check your exact drugs—especially anything for your heart, blood pressure, or blood clotting—against the tool on this page before you start this product.

For each ingredient in HT Combination 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.
Motherwort extract
Cns Depressants
Theoretically, taking motherwort concomitantly with other CNS depressants may increase the risk of sedation.
Motherwort has been reported to cause CNS depression and sedation.
Hawthorn
Nitrates
Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Phosphodiesterase-5 Inhibitors
Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.
Anticoagulant/Antiplatelet Drugs
Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.
Beta-Blockers
Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.
Calcium Channel Blockers
Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Digoxin (Lanoxin)
Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.
Myrrh Gum
Antidiabetes Drugs
Theoretically, myrrh might increase the risk of hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research suggests that myrrh has hypoglycemic effects.
Warfarin (Coumadin)
Theoretically, myrrh might decrease the effectiveness of warfarin.
In one case, a patient who was previously stable on warfarin had a significant decline in international normalized ratio (INR) following consumption of an aqueous extract of myrrh.
