HelloPharmacist Scorecard of Elderberry+ Immune Support by Native Remedies

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
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Formula” is a proprietary blend — the label gives one combined amount (4,500 mg) without saying how much of each component you get.

Elderberry+ Immune Support contains 3 active ingredients. Elderberry is the primary herb, included for its traditional immune-support role.

Astragalus and Echinacea purpurea round out the formula, both traditionally used in herbal medicine to support immune function. The product also contains glycerin and deionized water as inactive ingredients to preserve and deliver the liquid formula.

Does it work?

Insufficient evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: immune support and respiratory health.
  • We looked for evidence on: Influenza, Lower respiratory tract infections, Upper respiratory tract infection (URTI), Respiratory tract infections, Coronavirus disease 2019 (COVID-19), Cold and flu symptoms — and 2 related terms.
  • The closest evidence on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Lower respiratory tract infections.
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI).

The evidence we hold doesn't establish how well any of these three ingredients work for their intended uses. Elderberry shows insufficient reliable evidence for allergic rhinitis, cardiovascular disease, chronic fatigue, COPD, cognitive function, and respiratory infections.

Astragalus and Echinacea likewise have insufficient evidence for the conditions listed in our data — including asthma, angina, hay fever, and several others. If you're looking for proof this formula prevents colds or supports immunity, that evidence isn't in the facts we have.

The evidence, ingredient by ingredient Elderberry Astragalus Echinacea

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Elderberry extracts made from ripe, cooked berries are generally well tolerated. However, raw or unripe elderberries, seeds, leaves, and bark can be toxic and cause nausea, vomiting, severe diarrhea, weakness, dizziness, numbness, and even stupor — but cooking eliminates these toxins.

One rare case reported autoimmune hepatitis (liver inflammation) in a patient taking elderberry for years; symptoms resolved after stopping the supplement and starting treatment. Astragalus is well tolerated short-term in healthy adults, though human safety data is limited; isolated reports mention dizziness and temporary heart palpitations, though these may not have been caused by astragalus itself.

Echinacea is generally well tolerated but can trigger allergic reactions — especially in people sensitive to ragweed and related plants — ranging from rash and runny nose to severe reactions like anaphylaxis. Rare cases of echinacea-induced hepatitis have been reported.

For pregnancy, elderberry safety data is insufficient, so it's best avoided; astragalus and echinacea also have insufficient safety information during pregnancy and should be avoided.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Elderberry, Astragalus, Echinacea.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 898 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Elderberry+ Immune Support, double-check with your pharmacist if you use immunosuppressants (moderate risk), cancer drugs like pazopanib, etoposide, or cyclophosphamide (moderate), antidiabetes medications (moderate), lithium (moderate), antiretrovirals like lopinavir/ritonavir (minor), blood thinners like warfarin (minor), sedatives like midazolam (minor), or caffeine-containing products (moderate). No interactions are documented for the proprietary blend component alone, but that's because its specific ingredients are listed separately above.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is not a good fit if you take immunosuppressants, cancer medications, blood thinners, lithium, diabetes drugs, or antiretrovirals — the interaction risks are real and significant. If you're considering it for general immune support, know that the evidence for how well it works simply isn't established in our data.

Talk with your pharmacist or doctor before starting, especially if you have any prescriptions.

Echinacea purpurea12 drug types · 816 drugs

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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
Immunosuppressants

Echinacea has immunostimulant activity which may interfere with immunosuppressant therapy.
Theoretically, echinacea may interfere with immunosuppressant therapy because of its immunostimulant activity.

Likelihood Possible Evidence B
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.

Likelihood Unlikely Evidence B
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.

Likelihood Unlikely Evidence A
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.

Likelihood Unlikely Evidence B
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.

Likelihood Unlikely Evidence B
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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
Echinacea purpurea full monograph & interactions

Astragalus4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D

Elderberry2 drug types · 121 drugs

Immunosuppressants

Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor.

Likelihood Possible Evidence B
Pazopanib (Votrient)

Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 4 weeks for soft-tissue sarcoma developed severe nausea, loose stools, and elevated alanine transaminase and aspartate transaminase levels and was diagnosed with grade 3 liver injury. The patient reported taking elderberry supplements for 2 years, dose unspecified, and was also taking a multivitamin and a calcium supplement. The patient's symptoms and liver enzyme levels improved upon discontinuation of pazopanib and all supplements. Pazopanib treatment was re-initiated, at a lower dose, with no further evidence of liver injury. It was unclear in this case report if the elderberry supplements were derived from the berry, the flower, or the combination.

Elderberry+ Immune Support by Native Remedies: Common Questions

Does Elderberry+ Immune Support by Native Remedies interact with any medications?
Yes. Based on its ingredients, Elderberry+ Immune Support has a known interaction with 897 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Elderberry+ Immune Support contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is it safe to take this during pregnancy or while breastfeeding?
No. Elderberry safety data is insufficient in pregnancy, so it's best avoided. Astragalus and echinacea also lack reliable safety information for pregnancy and breastfeeding, so they should be avoided too. Talk with your doctor before taking any of these if you're pregnant, planning to become pregnant, or nursing.
Can this supplement cause side effects?
Most people tolerate it without trouble, but side effects are possible. Echinacea can cause abdominal pain, nausea, vomiting, diarrhea, constipation, or rashes. Rare but serious reactions include severe allergies (especially if you're sensitive to ragweed) and, in isolated cases, hepatitis. If you take raw elderberries instead of cooked ones, you risk nausea, vomiting, severe diarrhea, and dizziness — cooking eliminates that risk.
Does this actually prevent colds or boost immunity?
The evidence we have doesn't establish how well it works for respiratory infections, allergies, chronic fatigue, or other common uses. All three ingredients — elderberry, astragalus, and echinacea — show insufficient reliable evidence for the conditions in our data, so we can't say whether it delivers on its immune-support promise.
What does 'proprietary formula' mean on the label?
It means the exact amounts of each ingredient are blended and kept confidential by the maker. The individual ingredients are listed separately so you and your pharmacist can check for interactions with your medications.
Should I be worried about the taste or how to take this liquid?
The facts we have don't cover dosing instructions or taste, so check the label on your bottle or call the maker. Your pharmacist can also walk you through how to use it.
