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
Pure Herbs HT Combination is a liquid containing 3 active ingredients: myrrh resin extract, motherwort aerial parts extract, and hawthorn flower, fruit, and leaf extract. There are no inactive ingredients listed.
Each of these plant extracts has a long history in traditional medicine, though the evidence supporting their specific uses varies.
Does it work?
Not established
The evidence for this combination's effectiveness is limited. Myrrh resin extract has been rated likely ineffective for schistosomiasis, with insufficient evidence for back pain, cancer, common cold, dental implant complications, and Crohn disease.
Motherwort aerial parts extract is possibly effective for bleeding, but evidence is insufficient for alcohol use disorder, amenorrhea, anxiety, and asthma. Hawthorn flower, fruit, and leaf extract similarly lacks sufficient reliable evidence for angina, anxiety, heart rhythm problems, atherosclerosis, cardiovascular disease, and cognitive function.
The product's effectiveness for its intended use is not established in our data.
How safe is it?
Well-documented data
Myrrh resin extract is likely unsafe in pregnancy—it's traditionally believed to stimulate the uterus—and has been linked to severe abdominal pain in a pregnant woman. Oral safety for myrrh hasn't been well studied; at doses of 2–4 grams it may cause diarrhea, and topically it can cause dermatitis.
Motherwort aerial parts extract is also likely unsafe in pregnancy for the same reason and may cause diarrhea or stomach irritation when taken by mouth; amounts over 3 grams can cause uterine bleeding. Hawthorn flower, fruit, and leaf extract is generally well tolerated in studies but should be avoided in pregnancy and during breastfeeding due to insufficient safety data; rare cases of serious allergic reactions affecting the kidneys have been reported, and heart palpitations or changes in heart rate have occurred in some patients.
Meds to double-check
Major interaction found
Before taking this product, double-check with your doctor or pharmacist if you take nitrates or erectile dysfunction medications (Major risk of blood pressure drop), diabetes drugs, warfarin or other blood thinners, CNS depressants like opioids or sedatives, beta-blockers, calcium channel blockers, or digoxin. These are the medication types most likely to interact with the ingredients in this combination.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.
This combination is not recommended during pregnancy or breastfeeding. If you take any medications for heart conditions, blood pressure, diabetes, bleeding disorders, or sedation, talk with your doctor or pharmacist before starting—the interactions here can be serious.
Even if you're generally healthy, heart conditions require medical supervision, so check with your own healthcare provider first.

HT Combination by Pure Herbs Drug Interactions
HelloPharmacist Interaction Report
Pure Herbs HT Combination contains three active ingredients—myrrh resin extract, motherwort aerial parts extract, and hawthorn flower, fruit, and leaf extract—that together carry documented interactions with medications.
The most serious concern is hawthorn's Major-severity interaction with nitrates (drugs like nitroglycerin) and phosphodiesterase-5 inhibitors (erectile dysfunction medications); both can cause additive blood vessel relaxation and dangerous drops in blood pressure.
Read the full breakdown — every affected drug type, severity by severity
Myrrh resin extract may increase the risk of low blood sugar (hypoglycemia) with diabetes medications and may reduce how well warfarin (a blood thinner) works. Motherwort aerial parts extract can add to the sedating effects of CNS depressants—medications like opioids, sedatives, and some antidepressants.
Hawthorn also carries Moderate-severity interactions with beta-blockers, blood thinners and antiplatelet drugs, calcium channel blockers, and digoxin (a heart medication), potentially causing additive blood pressure drops, increased bleeding risk, or amplified heart effects.
Altogether, these interactions span 506 individual medications. Before starting this product, check with your doctor or pharmacist about any blood pressure medications, heart drugs, diabetes treatments, blood thinners, or sedating medications you take.

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 Aerial Parts 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 Flower, Fruit, Leaf Extract
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 Resin Extract
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.
