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 7 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (2 mL) without saying how much of each component you get.

This 7-ingredient blend combines herbal extracts traditionally used for sinus support. The active ingredients are osha root, kudzu root, echinacea purpurea (flower and root), eyebright herb, horseradish root, bayberry root bark, and collinsonia whole plant.

The product comes as a liquid formulation suspended in distilled water, ethyl alcohol, and vegetable glycerin.

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: Supports healthy sinus function.
  • We looked for evidence on: Allergic rhinitis (hay fever), Common cold, Cough, Influenza, Pharyngitis, Respiratory tract infections — and 4 related terms.
  • The closest evidence on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Common cold, Cough, Pharyngitis, Rhinosinusitis.
  • Also on file: Horseradish is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections.

The evidence supporting these ingredients for sinus-related concerns is limited. Osha root and eyebright have insufficient reliable evidence for their traditional uses in respiratory health and hay fever.

Kudzu has been shown to be possibly effective for alcohol use disorder, but lacks reliable evidence for hay fever or other respiratory conditions. Echinacea and horseradish likewise show insufficient reliable evidence for the conditions they're traditionally used for, including cough, cold, and respiratory infections.

The safety data we hold does not establish effectiveness for any of these ingredients in treating sinus issues specifically.

The evidence, ingredient by ingredient Osha Kudzu Echinacea Eyebright Horseradish Bayberry Stone Root

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 6 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Several ingredients in this blend carry cautions about short-term and long-term safety. Osha root has limited safety data and wild plants can be confused with poisonous look-alikes; it's traditionally avoided in pregnancy and not studied for breastfeeding safety.

Kudzu is generally well tolerated short-term, but long-term safety isn't established, and it should be avoided during pregnancy and breastfeeding. Echinacea is well tolerated orally but may trigger allergic reactions, especially in people sensitive to ragweed and related plants (such as daisies and marigolds); rare cases of liver inflammation (hepatitis) have been reported.

Eyebright may cause confusion, headache, nausea, constipation, cough, and shortness of breath. Horseradish in large amounts can cause stomach upset, bloody vomiting, diarrhea, and in rare cases, fainting.

Bayberry can cause stomach irritation, vomiting, and liver damage due to its tannin content. None of these ingredients have adequate safety data for pregnancy or breastfeeding; talk with your pharmacist or doctor before use if you're pregnant, nursing, or planning either.

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

Why this rating?
  • 4 of the 7 matched ingredients can interact with medications — Eyebright, Horseradish, Kudzu, Echinacea.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,138 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 this product, check whether you're on any blood thinners (anticoagulants or antiplatelet drugs), drugs processed by your liver's CYP1A2 or CYP3A4 enzymes (including caffeine, many antidepressants, statins, and others), diabetes medications, immune-suppressing drugs, thyroid hormone replacement, methotrexate, tamoxifen, etoposide, warfarin, lopinavir/ritonavir, or midazolam. These carry Moderate or Minor severity interactions with ingredients in this blend.

Echinacea purpurea flower and root 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 flower and root extract full monograph & interactions

Kudzu root extract7 drug types · 584 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, kudzu may increase the risk of bleeding if used with antiplatelet or anticoagulant drugs.
Kudzu isoflavones are reported to have antiplatelet activity.

Likelihood Possible Evidence D
Caffeine

Theoretically, taking kudzu with caffeine might increase levels of caffeine.
In healthy males injected with the kudzu constituent puerarin, caffeine clearance and metabolism is inhibited. This effect has been attributed to inhibition of cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if taking kudzu orally would have this same effect.

Likelihood Probable Evidence D
Estrogens

Theoretically, kudzu might alter the effects of estrogen therapy.
Some research suggests that kudzu has estrogenic effects. This may enhance or inhibit the effects of estrogen therapy.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, concomitant use might have additive hepatotoxic effects.
There is some concern that kudzu can adversely affect the liver.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Theoretically, taking kudzu with methotrexate might increase the risk of methotrexate toxicity.
Preclinical research suggests that kudzu extract greatly reduces the elimination and increases the toxicity of methotrexate. Kudzu might inhibit organic anion transporters (OATs) that are responsible for hepatobiliary and renal excretion of anions, similar to the interaction between methotrexate and non-steroidal anti-inflammatory drugs (NSAIDs).

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, kudzu might interfere with tamoxifen activity.
Some research suggests that kudzu may have estrogenic effects.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking kudzu with antidiabetes drugs might increase the risk of hypoglycemia.
Kudzu might lower blood glucose levels and have additive effects in patients treated with antidiabetic agents. The dose of diabetes medications might need to be adjusted.

Likelihood Unlikely Evidence D
Kudzu root extract full monograph & interactions

Eyebright herb extract1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, eyebright might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that eyebright lowers blood glucose levels.

David Winston's Sinus Support Compound by Herbalist & Alchemist: Common Questions

Does David Winston's Sinus Support Compound by Herbalist & Alchemist interact with any medications?
Yes. Based on its ingredients, David Winston's Sinus Support Compound has a known interaction with 1,137 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
David Winston's Sinus Support Compound contains 7 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.
Can I take this if I'm pregnant or breastfeeding?
The ingredients in this blend do not have adequate safety data for pregnancy or breastfeeding. Osha, kudzu, eyebright, and bayberry are traditionally avoided or not well studied during pregnancy; osha, kudzu, eyebright, and bayberry have insufficient data for breastfeeding. Talk with your pharmacist or doctor for personalized advice before using this product.
What are the main ingredients and what are they supposed to do?
This blend contains osha root, kudzu root, echinacea, eyebright, horseradish, bayberry, and collinsonia—all traditionally used for sinus and respiratory support. However, the evidence supporting them for these uses is insufficient or not established in the data we hold.
Could this product cause allergic reactions?
Yes. Echinacea may trigger allergic reactions in people sensitive to ragweed or related plants (daisies, marigolds, chrysanthemums). Cases of hives, rash, swelling, and even anaphylaxis have been reported. Horseradish can also cause allergic reactions when applied to skin.
What side effects might I experience?
Eyebright may cause confusion, headache, nausea, constipation, cough, and shortness of breath. Horseradish in large amounts can cause stomach upset, vomiting, and diarrhea. Echinacea typically causes mild digestive upset, nausea, or rash. Kudzu may cause nausea, bloating, or dizziness in some people.
Is this safe to use long-term?
Long-term safety is not well established for most of these ingredients. Kudzu and echinacea are generally well tolerated short-term, but data beyond a few weeks or months are limited. Horseradish and bayberry carry concerns about stomach irritation and liver effects with larger amounts over time.
Does this work for sinus infections or sinus congestion?
The evidence is insufficient to say. These ingredients are traditionally used for sinus and respiratory conditions, but our data show no reliable evidence that they work for hay fever, sinusitis, cough, cold, or respiratory infections.
