HelloPharmacist Scorecard of SinusFree by Planetary Herbals

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 5 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1 mL) without saying how much of each component you get.

SinusFree is a liquid formula with five active herbal ingredients. Horseradish, chrysanthemum, thyme, schizonepeta, and yarrow make up the active blend, each included for its traditional use in respiratory and sinus support.

The product also contains grain alcohol and purified water as inactive ingredients.

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: supporting free flow of mucus and normal breathing.
  • We looked for evidence on: Respiratory tract infections, Bronchitis, Common cold, Cough, Laryngitis, Tonsillitis — and 4 related terms.
  • The closest evidence on file: Yarrow is rated "Insufficient Reliable Evidence To Rate" for Tonsillitis (Natural Medicines).
  • Also on file: Horseradish is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections.
  • Also on file: Thyme is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Common cold, Cough, Tonsillitis, and more.

The evidence supporting these ingredients for sinus and respiratory health is limited. Horseradish, thyme, schizonepeta, and yarrow all carry effectiveness ratings of insufficient reliable evidence for the conditions they are traditionally used for—including respiratory tract infections, bronchitis, and common cold.

Chrysanthemum likewise has insufficient evidence for conditions like common cold and headache. The data we hold does not establish that this product works for its intended purpose.

The evidence, ingredient by ingredient Horseradish Chrysanthemum Thyme Schizonepeta Yarrow

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horseradish is generally well tolerated in food amounts but can irritate the digestive tract and mucous membranes in concentrated form; large amounts may cause gastrointestinal upset, bloody vomiting, or diarrhea, and in rare cases, fainting. Thyme is safe in food and medicinal amounts generally but the concentrated essential oil can be toxic if swallowed.

Chrysanthemum can trigger allergic reactions in sensitive people, with an estimated 60% of Europeans showing some allergy risk. Schizonepeta has limited human safety data; one combination product containing it reported nausea, vomiting, dizziness, and headache, though it's unclear whether schizonepeta or other ingredients were responsible.

Yarrow is generally well tolerated but can cause skin reactions and has been associated with airborne contact dermatitis and asthma in rare cases.

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?
  • 4 of the 5 matched ingredients can interact with medications — Yarrow, Horseradish, Thyme, Schizonepeta.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 1,001 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 SinusFree, double-check with your doctor or pharmacist if you take thyroid hormone replacement, estrogen therapy, blood thinners or antiplatelet drugs, anticholinergic or cholinergic medications, lithium, or any drug processed by the cytochrome P450 enzymes 2D6, 1A2, 3A4, or 2E1—a very large group that includes many antidepressants, pain relievers, statins, and antihistamines. The interaction checker on this page can tell you whether any of your medications fall into these categories.

Schizonepeta4 drug types · 797 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Animal research suggests that schizonepetin, a monoterpene constituent of schizonepeta, inhibits cytochrome P450 (CYP) 1A2. Theoretically, schizonepeta might increase the effects and side effects of CYP1A2 substrates.
Some substrates of CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, zileuton (Zyflo), zolmitriptan (Zomig), and others.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Animal research suggests that schizonepetin, a monoterpene constituent of schizonepeta, inhibits cytochrome P450 (CYP) 2D6. Theoretically, schizonepeta might increase the effects and side effects of CYP2D6 substrates.
Some substrates of CYP2D6 include amitriptyline (Elavil), codeine, desipramine (Norpramin), flecainide (Tambocor), haloperidol (Haldol), imipramine (Tofranil), metoprolol (Lopressor, Toprol XL), ondansetron (Zofran), paroxetine (Paxil), risperidone (Risperdal), tramadol (Ultram), venlafaxine (Effexor), and others.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Animal research suggests that schizonepetin, a monoterpene constituent of schizonepeta, inhibits cytochrome P450 (CYP) 2E1. Theoretically, schizonepeta might increase the effects and side effects of CYP2E1 substrates.
Some substrates of CYP2E1 include acetaminophen, chlorzoxazone (Parafon Forte), ethanol, theophylline, and anesthetics such as enflurane (Ethrane), halothane (Fluothane), isoflurane (Forane), and methoxyflurane (Penthrane).

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Animal research suggests that schizonepetin, a monoterpene constituent of schizonepeta, induces cytochrome P450 (CYP) 3A4. Theoretically, schizonepeta might decrease the effects of CYP3A4 substrates.
Some substrates of CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and numerous others.

Likelihood Possible Evidence D
Schizonepeta full monograph & interactions

Thyme4 drug types · 379 drugs

Anticholinergic Drugs

Theoretically, concurrent use of anticholinergic drugs and thyme essential oil might reduce the effects of anticholinergic drugs.
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE). However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that thyme leaf extract has antiplatelet effects. However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concurrent use of cholinergic drugs and thyme essential oil might cause additive cholinergic effects.
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE). However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, thyme might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that thyme has estrogen receptor-binding activity and phytoestrogen content. However, this effect has not been observed in humans.

Likelihood Possible Evidence D

SinusFree by Planetary Herbals: Common Questions

Does SinusFree by Planetary Herbals interact with any medications?
Yes. Based on its ingredients, SinusFree has a known interaction with 1,000 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
SinusFree contains 5 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 SinusFree while pregnant?
The safety data aren't clear enough to recommend it. Horseradish should be avoided in pregnancy, chrysanthemum safety is not established, thyme appears likely safe, but schizonepeta and yarrow are not recommended during pregnancy. Talk with your doctor or pharmacist for personalized guidance before starting.
Is it safe to breastfeed while taking SinusFree?
Safety during breastfeeding varies by ingredient. Horseradish data are conflicting, chrysanthemum is not well studied, thyme appears likely safe, but schizonepeta and yarrow lack enough safety information. Discuss this with your doctor or pharmacist to see if it's right for you.
What is horseradish in this formula supposed to do?
Horseradish is included for traditional respiratory and urinary support, but the evidence is insufficient to confirm it works for these uses. It's most familiar as a food condiment in small amounts.
Can this product cause allergic reactions?
Yes. Chrysanthemum commonly triggers allergies—about 60% of Europeans have some sensitivity. Thyme, yarrow, and other ingredients can also cause skin reactions or respiratory symptoms in sensitive people. If you have known allergies to plants in the daisy or mint families, mention this to your doctor or pharmacist before using.
What are the inactive ingredients in SinusFree?
The formula contains grain alcohol and purified water as inactive ingredients. If you avoid alcohol, note that the grain alcohol is present in this liquid formulation.
Does this product actually work for sinus problems?
The evidence for these ingredients is insufficient to say whether they work for sinus or respiratory issues. While they're used traditionally, reliable clinical data supporting their effectiveness for these purposes are limited.
