HelloPharmacist Scorecard of ImmunoBoost by Herbs Etc.

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 9 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (0.75 mL) without saying how much of each component you get.

ImmunoBoost contains 9 ingredients, five of which are active herbal extracts. The main players are astragalus root extract, three different forms of echinacea (purpurea and angustifolia, in root, herb, and flower versions), osha root extract, and calendula flower extract.

The other actives are astragalus and echinacea in a proprietary blend — that means we can't see exactly how much of each form you're getting. The inactive ingredients are alcohol, purified water, and glycerin, which help preserve and carry the herbs.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Promotes essential immune system health.
  • We looked for evidence on: Chemotherapy-induced leukopenia, Coronavirus disease 2019 (COVID-19), Influenza, Upper respiratory tract infection (URTI), Immune function, Infection prevention — and 2 related terms.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-induced leukopenia (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI).
  • Also on file: Echinacea is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Influenza, Coronavirus disease 2019 (COVID-19).

The evidence for what this product actually does isn't strong. All the active ingredients — astragalus, echinacea, osha, and calendula — have insufficient reliable evidence to support claims for most conditions.

The data we hold doesn't establish that ImmunoBoost works for any particular health goal.

The evidence, ingredient by ingredient Astragalus Osha Echinacea Calendula

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 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Astragalus is generally well tolerated short-term in healthy adults, though quality safety data is limited. The echinacea extracts are also generally well tolerated short-term but can trigger allergic reactions, especially in people sensitive to ragweed or related plants like chrysanthemums, marigolds, or daisies.

Rare serious effects reported with echinacea include severe allergic reactions and hepatitis. Astragalus has been associated with dizziness and, in one trial, a type of chest pain called lacunar angina — though it's unclear whether astragalus caused it.

Osha has limited safety data; wild osha can be confused with poisonous look-alikes. Calendula can cause allergic skin reactions.

The product contains alcohol, which you'll want to know about if you avoid it.

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 4 matched ingredients can interact with medications — Calendula, 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: 1,032 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 you start, check whether you take immunosuppressants (like tacrolimus or mycophenolate), lithium, cyclophosphamide or other chemotherapy, any diabetes medication, drugs metabolized by your liver (CYP1A2 or CYP3A4 substrates — ask your pharmacist if unsure), caffeine-containing medications, warfarin, lopinavir/ritonavir, or midazolam. The echinacea content could also interact with sedating drugs.

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 is a multi-ingredient herbal liquid, but we don't have evidence it works for any specific condition. More importantly, if you take any prescription medications — especially immunosuppressants, lithium, diabetes drugs, blood thinners, chemotherapy, or sedatives — you need to check your exact medications with the tool below before starting.

Echinacea purpurea Seed Extract12 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 Seed Extract full monograph & interactions

Calendula Flower Extract, Fresh1 drug type · 248 drugs

Cns Depressants

Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Although some animal research has suggested that a saponoside constituent in calendula may have sedative effects, calendula has been used for over 30 years without reports of sedation in humans.

Likelihood Unlikely Evidence D
Calendula Flower Extract, Fresh full monograph & interactions

Astragalus Root Extract4 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.

ImmunoBoost by Herbs Etc.: Common Questions

Does ImmunoBoost by Herbs Etc. interact with any medications?
Yes. Based on its ingredients, ImmunoBoost has a known interaction with 1,031 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
ImmunoBoost contains 9 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 this safe to take if I'm pregnant or breastfeeding?
No. Astragalus should be avoided in pregnancy and while breastfeeding because there isn't enough safety data. Osha and calendula also lack reliable safety data for pregnancy and breastfeeding, so they're best avoided too unless your doctor specifically approves. The echinacea pregnancy data isn't on file, so ask your pharmacist or doctor for personalized advice.
Can echinacea really boost my immune system?
The evidence we have isn't strong enough to confirm that echinacea works for immune function or for preventing or treating any specific condition. Echinacea does seem to stimulate immune activity in theory, but that's actually why it can interfere with immunosuppressant medications.
What are the most common side effects of echinacea?
Echinacea is generally well tolerated, but some people report abdominal pain, constipation, diarrhea, heartburn, nausea, vomiting, or rashes. Allergic reactions are more common in people sensitive to ragweed or plants in that family. Severe allergic reactions and liver inflammation are rare but have been reported.
Will this liquid interact with my caffeine intake?
Yes. The echinacea in this product can increase caffeine levels in your blood by about 30%, so if you drink coffee, tea, or take caffeine pills, you might feel more jittery or have heart palpitations. That's something to watch for.
Why does the label say 'proprietary blend' for some ingredients?
That means the manufacturer hasn't disclosed exactly how much of each echinacea form or astragalus is in the product — they're protecting their formula. It makes it harder to know exactly what dose you're getting of each ingredient.
Is osha root safe?
We don't have enough data to say. Wild osha can look very similar to poisonous plants, which is a real concern. If you're interested in osha, talk to your pharmacist about whether the source and quality can be verified.
