HelloPharmacist Scorecard of Herbal Defense by Herbally Grounded
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
Herbal Defense contains three active ingredients delivered in liquid form. Myrrh is a resin traditionally used in herbal medicine.
Echinacea angustifolia is a plant extract, and peppermint leaf is an herbal ingredient — together they make up a proprietary blend whose exact proportions are not disclosed. The product also contains inactive ingredients: glycerin, deionized water, and apple cider vinegar, which serve as preservatives and carriers in the liquid formula.
Does it work?
Not established
The evidence for these ingredients is mixed. Peppermint leaf has the strongest data: it's likely effective for irritable bowel syndrome and possibly effective for indigestion, nausea from chemotherapy, and related digestive concerns.
Myrrh and echinacea angustifolia lack sufficient reliable evidence for the conditions tested — the data rates myrrh as likely ineffective for schistosomiasis and insufficient for back pain, cancer, colds, dental inflammation, and Crohn disease. Echinacea shows insufficient evidence for anxiety, athletic performance, ADHD, burns, chronic fatigue, and migraines.
If you're considering this product for a specific health goal, check whether the evidence backs the use you have in mind.
How safe is it?
Well-documented data
Peppermint leaf is rated likely safe in pregnancy and lactation and is generally well tolerated orally; common side effects include abdominal pain, diarrhea, heartburn, nausea, and rashes. Rare serious reactions include severe allergies and hepatitis.
Echinacea is generally well tolerated short-term but may trigger allergic reactions, especially in people sensitive to ragweed and related plants (ragweed, daisies, chrysanthemums, marigolds); it can cause abdominal pain, constipation, diarrhea, heartburn, nausea, rashes, and stomach upset. Rare cases of hepatitis have been reported.
Myrrh has limited oral safety data; it may cause diarrhea at doses of 2–4 grams and is traditionally said to stimulate the uterus — the safety data advises against it during pregnancy. One case reported severe abdominal pain in a pregnant woman taking myrrh as a traditional remedy, which resolved when she stopped.
No safety data is on file for myrrh in lactation.
Meds to double-check
Moderate interaction found
Before taking Herbal Defense, check your medications against these drug types — worst severity first: diabetes medications, blood thinners (warfarin), immunosuppressants, etoposide (a chemotherapy drug), CYP1A2 substrates (including caffeine), CYP2C19 substrates, CYP2C9 substrates, CYP3A4 substrates (including midazolam, felodipine, cyclosporine, and protease inhibitors like lopinavir/ritonavir). If you take any of these, run them through the medication checker on this page before you start.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This product may be worth considering if you're interested in digestive support, particularly peppermint's benefits for irritable bowel syndrome. However, it carries moderate interactions with diabetes drugs, blood thinners, enzyme inhibitors (CYP1A2, CYP2C19, CYP2C9, CYP3A4), immunosuppressants, and etoposide, so it's not suitable if you take any of those.
Avoid during pregnancy due to myrrh. Talk to your pharmacist before starting, especially if you take prescription medications.

Herbal Defense by Herbally Grounded Drug Interactions
HelloPharmacist Interaction Report
Herbal Defense by Herbally Grounded is a liquid supplement with three active ingredients, and it does interact with a number of medications.
The most serious concern is myrrh, which moderately increases the risk of low blood sugar (hypoglycemia) when taken with diabetes medications — animal and lab research suggests myrrh can lower blood sugar on its own.
Read the full breakdown — every affected drug type, severity by severity
Myrrh also moderately interacts with warfarin (a blood thinner); one case report showed a patient's INR (a measure of how well warfarin is working) dropped significantly after taking myrrh extract, suggesting it may reduce warfarin's effectiveness. Echinacea angustifolia moderately affects several enzyme systems: it can inhibit CYP1A2 and increase caffeine levels by roughly 30%, inhibit CYP2C19 and CYP2C9 substrates (theoretical risk in humans so far), and has variable effects on CYP3A4 substrates — though clinical trials up to one month showed no significant effect on drugs like midazolam.
Echinacea also moderately interferes with immunosuppressants due to its immune-stimulating activity, and one case linked it to increased etoposide toxicity.
Peppermint leaf moderately inhibits CYP2C19, CYP2C9, and CYP3A4 substrates — one clinical study showed it increased felodipine levels — and theoretically may raise cyclosporine levels. Minor interactions include echinacea with warfarin (increased clearance, likely not clinically significant) and with lopinavir/ritonavir and midazolam (theoretical or small observed effects), and peppermint with CYP1A2 substrates (lab evidence, but peppermint tea did not affect caffeine metabolism in one study).
Altogether, these interactions span 945 individual medications. Use the medication checker below to verify your specific drugs before starting this product.

For each ingredient in Herbal Defense 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.
Echinacea angustifolia
Caffeine
Echinacea can increase plasma levels of caffeine by inhibiting its metabolism.
Echinacea seems to increase plasma concentrations of caffeine by around 30%. This is likely due to inhibition of cytochrome P450 1A2 (CYP1A2) by echinacea.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Echinacea might inhibit the metabolism of CYP1A2 and increase plasma levels of some drugs.
Echinacea appears to inhibit CYP1A2 enzymes in humans. Additionally, echinacea seems to increase plasma concentrations of caffeine, a CYP1A2 substrate, by around 30%. Theoretically, echinacea might increase levels of other drugs metabolized by CYP1A2.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Echinacea may induce hepatic CYP3A4 and inhibit intestinal CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Several clinical trials have shown that taking echinacea for up to one month does not significantly affect the metabolism of various CYP3A4 substrates, including midazolam, docetaxel, etravirine, lopinavir-ritonavir, and darunavir-ritonavir. However, other clinical research shows that echinacea may increase the clearance of midazolam, suggesting that echinacea might induce CYP3A4. The discrepancy is thought to be due to differing effects of echinacea on intestinal versus hepatic CYP3A4 enzymes. Echinacea appears to induce hepatic CYP3A4 but inhibit intestinal CYP3A4. In some cases, these effects might cancel each other out, but in others, drug levels may be increased or decreased depending on the level of effect at hepatic and intestinal sites. The effect of echinacea on CYP3A4 activity may differ depending on the CYP3A4 substrate.
Etoposide (Vepesid)
Echinacea may increase levels of etoposide.
In one report, concomitant use of etoposide and echinacea was associated with more severe thrombocytopenia than the use of etoposide alone, suggesting inhibition of etoposide metabolism. Etoposide is a cytochrome P450 3A4 (CYP3A4) substrate. Echinacea has variable effects on CYP3A4, but some studies have reported inhibition of the enzyme.
Immunosuppressants
Echinacea has immunostimulant activity which may interfere with immunosuppressant therapy.
Theoretically, echinacea may interfere with immunosuppressant therapy because of its immunostimulant activity.
Darunavir (Prezista)
Theoretically, echinacea may interfere with the metabolism of darunavir; however, a small clinical study found no effect.
Darunavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but administration of an E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg four times daily for 14 days did not affect darunavir/ritonavir pharmacokinetics in 15 HIV-infected patients.
Dayquil Severe
Echinacea is reported to have varying effects on a number of Cytochrome P450 metabolizing enzymes in the liver, including CYP1A2 and CYP3A4, which play a role in acetaminophen and dextromethorphan metabolism (both contained in DayQuil Severe), respectively. Studies have reported both enzyme inhibition and induction, making it difficult to predict clinically significant drug interactions with reliability. Specific drug interaction studies reporting definitive results are rare, and potential drug interactions involving echinacea should likely be taken on a case-by-case basis. Based on what we know about how acetaminophen and dextromethorphan are metabolized, the risk of a clinically significant interaction between echinacea and DayQuil Severe is low.
Docetaxel (Taxotere)
Theoretically, echinacea may interfere with the metabolism of docetaxel; however, a small clinical study found no effect.
Docetaxel is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea whole plant extract (Echinaforce, A. Vogel Biopharma AG) 20 drops three times daily for 2 weeks did not alter the pharmacokinetics of docetaxel in one clinical study.
Etravirine (Intelence)
Theoretically, echinacea may interfere with the metabolism of etravirine; however, a small clinical study found no effect.
Etravirine is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg three times daily for 14 days did not alter the pharmacokinetics of etravirine in HIV-infected patients.
Lopinavir/Ritonavir (Kaletra)
Theoretically, echinacea may interfere with the metabolism of lopinavir; however, a small clinical study found no effect.
Lopinavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but taking E. purpurea (Echinamide, Natural Factors Nutritional Products, Inc.) 500 mg three times daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in healthy volunteers.
Midazolam (Versed)
Theoretically, echinacea may increase the metabolism of intravenous midazolam.
Echinacea induces hepatic CYP3A4 and might decrease plasma levels of midazolam by about 20%, reducing the effectiveness of intravenous midazolam. Echinacea also appears to inhibit intestinal CYP3A4, which could theoretically increase the bioavailability of oral midazolam. This may cancel out the decrease in availability caused by induction of hepatic CYP3A4, such that overall plasma levels after oral administration of midazolam are not affected by echinacea.
Warfarin (Coumadin)
Echinacea seems to increase the clearance of warfarin, although the effect may not be clinically significant.
Preliminary clinical research in healthy male volunteers suggests that taking echinacea increases the clearance of the active S-isomer of warfarin after a single dose of warfarin, but there was not a clinically significant effect on the INR.
Peppermint Leaf
Cyclosporine (Neoral, Sandimmune)
Theoretically, peppermint oil might increase the levels and adverse effects of cyclosporine.
In animal research, peppermint oil inhibits cyclosporine metabolism and increases cyclosporine levels. Inhibition of cytochrome P450 3A4 (CYP3A4) may be partially responsible for this interaction. An interaction between peppermint oil and cyclosporine has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, peppermint might increase the levels of CYP2C19 substrates.
In vitro research shows that peppermint oil inhibits CYP2C19. So far, this interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, peppermint might increase the levels of CYP2C9 substrates.
In vitro research shows that peppermint oil inhibits CYP2C9. So far, this interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, peppermint might increase the levels of CYP3A4 substrates.
Clinical research in healthy volunteers shows that a single dose of peppermint oil 600 mg inhibits CYP3A4 enzymes and increases the AUC of felodipine, a CYP3A4 substrate. However, in vitro research suggests that peppermint oil only inhibits CYP3A4 at very high concentrations.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, peppermint might increase the levels of CYP1A2 substrates.
In vitro and animal research shows that peppermint oil and peppermint leaf inhibit CYP1A2. However, in clinical research, peppermint tea did not significantly affect the metabolism of caffeine, a CYP1A2 substrate. It is possible that the 6-day duration of treatment may have been too short to identify a difference.
Myrrh
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.
