HelloPharmacist Scorecard of 3 Echinacea by L.A. Naturals
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
3 Echinacea by L.A. Naturals is a liquid blend containing 4 ingredients: a proprietary blend base and three echinacea forms—fresh Echinacea angustifolia, fresh Echinacea purpurea, and dry Echinacea angustifolia—plus fresh ginger.
The echinacea species are traditional immune-support herbs, while ginger is included for its anti-inflammatory properties. The product also contains grain alcohol and deionized water as inactive ingredients.
Does it work?
Moderate evidence
The evidence we hold for echinacea shows insufficient reliable data to rate it for anxiety, athletic performance, ADHD, burns, chronic fatigue syndrome, or migraine headache. For ginger in this product, the data supports it as possibly effective for pregnancy-induced nausea and vomiting, dysmenorrhea (menstrual cramping), and osteoarthritis, but possibly ineffective for exercise-induced muscle soreness and chemotherapy-induced nausea.
Overall, the product's primary uses rest on limited evidence.
How safe is it?
Well-documented data
Echinacea is generally well tolerated for short-term use but may cause allergic reactions, particularly in people sensitive to ragweed and related plants like chrysanthemums, marigolds, and daisies. Common side effects include abdominal pain, constipation, diarrhea, heartburn, nausea, vomiting, and rashes.
Rare but serious reactions—severe allergic responses and hepatitis—have been reported; hepatitis-related cases occurred after several weeks of daily use. Ginger is generally well tolerated in typical amounts, though doses above 5 grams daily raise the risk of side effects.
Common mild effects include heartburn, diarrhea, burping, abdominal discomfort, and a peppery irritant sensation in the mouth and throat. Pregnancy safety for echinacea is rated possibly safe; for ginger, pregnancy use is likely to possibly safe, though you should talk with your doctor first.
Lactation data is not on file for either ingredient.
Meds to double-check
Moderate interaction found
Before you take this, check with your pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, phenprocoumon, aspirin, or others), diabetes medications, heart medications like nifedipine or losartan, immunosuppressants, the cancer drug etoposide, or benzodiazepines like midazolam—all ranked Moderate severity. Also flag any drug metabolized by CYP1A2 or CYP3A4 enzymes, or transported by P-glycoprotein.

3 Echinacea by L.A. Naturals Drug Interactions
HelloPharmacist Interaction Report
3 Echinacea by L.A.
Naturals contains echinacea species and ginger, both of which interact with a number of medications. The most serious interactions are Moderate in severity.
Read the full breakdown — every affected drug type, severity by severity
Echinacea may affect how your body metabolizes certain drugs. It can inhibit an enzyme called CYP1A2 (cytochrome P450 1A2), which increases levels of drugs processed this way—including caffeine, where it can raise blood levels by about 30%.
It also has variable effects on another major enzyme, CYP3A4, which means it could increase or decrease levels of drugs that depend on this pathway. Additionally, echinacea may increase levels of the cancer drug etoposide (VePesid) and interfere with immunosuppressant medications because of its immune-stimulating activity.
On warfarin (Coumadin), the effect appears minor and may not be clinically meaningful.
Ginger adds Moderate interactions with blood thinners and antiplatelet drugs (including warfarin and the anticoagulant phenprocoumon), drugs for diabetes, the blood-pressure medication losartan, and nifedipine (a heart medication). Ginger may also affect how your body handles CYP3A4 substrates and P-glycoprotein substrates, a group of transporter proteins that move drugs in and out of cells.
Altogether, these interactions span 1,075 individual medications. Use the medication checker on this page to verify your exact drugs before starting.

fresh Ginger
Anticoagulant/Antiplatelet Drugs
Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
Antidiabetes Drugs
Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.
Losartan (Cozaar)
Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.
Nifedipine (Procardia)
Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.
P-Glycoprotein Substrates
Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Phenprocoumon (Marcoumar, Others)
Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.
Warfarin (Coumadin)
Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.
Calcium Channel Blockers
Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.
Cyclosporine (Neoral, Sandimmune)
Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.
Metronidazole (Flagyl)
Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.
fresh 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.
