HelloPharmacist Scorecard of Sinus Relief 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
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 10 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Sinus Relief is a liquid blend of 10 ingredients. The active components are Red Peony, Forsythia, Platycodon, Angelica, Chrysanthemum, Magnolia, Xanthium, Ledebouriella, Schizonepeta, and Centipeda — combined in a proprietary blend, so individual amounts aren't listed on the label.

The product also contains grain alcohol and deionized 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: nasal congestion and sinus relief.
  • We looked for evidence on: Allergic rhinitis (hay fever), Common cold, Headache, Sinusitis, Rhinosinusitis.
  • The closest evidence on file: Peony is rated "Insufficient Reliable Evidence To Rate" for Migraine headache (Natural Medicines).
  • Also on file: Magnolia is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever), Headache.
  • Also on file: Chrysanthemum is rated "Insufficient Reliable Evidence To Rate" for Headache, Common cold.

The evidence supporting these ingredients is limited. Red Peony, Forsythia, Angelica, Chrysanthemum, Magnolia, and Schizonepeta all show insufficient reliable evidence for the conditions they've been studied for — meaning the research so far hasn't established whether they work.

Magnolia does have one condition marked as possibly effective: gingivitis (gum inflammation), though the overall evidence remains lean. We hold no effectiveness data for Platycodon, Ledebouriella, or Centipeda in our system.

The evidence, ingredient by ingredient Peony Forsythia Ashitaba Chrysanthemum Magnolia Siberian Cocklebur Schizonepeta

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 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 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.

Most of these ingredients are generally well tolerated for short-term use, but high-quality safety data are limited across the board. The main concern is Xanthium (Siberian cocklebur), which carries a warning that it's generally regarded as unsafe — it has caused serious poisoning and is linked to liver failure, severe low blood sugar, heart rhythm problems, and bleeding.

Avoid it entirely during pregnancy and breastfeeding. Red Peony is possibly unsafe in pregnancy and unsafe while breastfeeding.

Forsythia, Angelica, Magnolia, and Schizonepeta all lack adequate safety data in pregnancy and breastfeeding — the safety notes advise against use in both periods. Chrysanthemum can trigger allergic reactions, especially contact dermatitis and, rarely, asthma in sensitive people; safety in pregnancy and breastfeeding is not established.

Common side effects from peony include stomach upset (nausea, diarrhea, bloating, loss of appetite).

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 6 of the 7 matched ingredients can interact with medications — Peony, Magnolia, Schizonepeta, Forsythia, Ashitaba, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,362 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 with your doctor or pharmacist if you take antidiabetes medications, blood thinners (anticoagulants or antiplatelet drugs), or any drug that affects your liver or kidneys — these carry the most serious risks. Additionally, confirm use if you take medications metabolized by your liver's cytochrome P450 enzymes (CYP1A2, CYP2D6, CYP2E1, or CYP3A4), or if you take hormone-based birth control or estrogen replacement therapy, as several ingredients may alter how these drugs work.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

This product is a traditional herbal blend for sinus symptoms, but the evidence that it works is insufficient. More importantly, several ingredients carry significant interaction risks — especially Xanthium, which poses major concerns with kidney, liver, and diabetes medications.

If you're pregnant, breastfeeding, or take any prescription medications (particularly blood thinners, diabetes drugs, or heart and mood medications), talk with your doctor or pharmacist before trying this product. Even if none of those apply, confirm with your pharmacist that your specific medications won't interact with these herbs.

Red Peony7 drug types · 811 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, combining peony with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that peony might have antiplatelet, anticoagulant, and antithrombotic effects.

Likelihood Possible Evidence D
Clozapine (Clozaril)

Theoretically, peony might increase the levels and clinical effects of clozapine.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on cytochromes P450 (CYP) 1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro and animal research shows that peony extract has estrogenic activity. Concomitant use might also increase the risk for estrogen-related adverse effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

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

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.
In vitro and animal research shows that peony extract has estrogenic activity. Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Theoretically, peony might reduce the levels and clinical effects of phenytoin.
Animal research shows that taking peony root reduces levels of phenytoin. Some researchers suggest that peony root might affect cytochrome P450 (CYP) 2C9, which metabolizes phenytoin. However, preliminary research in humans shows that peony root does not alter levels of losartan (Cozaar), which is also metabolized by CYP2C9.

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

Xanthium3 drug types · 662 drugs

Antidiabetes Drugs

Siberian cocklebur seedlings and seeds have caused severe hypoglycemia in humans. Hypoglycemia occurs soon after consumption and worsens with time in most cases. Do not use Siberian cocklebur in people taking medications that also lower blood glucose.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Likelihood Likely Evidence B
Hepatotoxic Drugs

Siberian cocklebur can adversely affect the liver. It has been linked to many cases of hepatotoxicity and some cases of liver failure. Theoretically, concomitant use with other potentially hepatotoxic drugs might increase the risk of developing liver damage. Some of these drugs include acarbose (Precose, Prandase), amiodarone (Cordarone), atorvastatin (Lipitor), azathioprine (Imuran), carbamazepine (Tegretol), cerivastatin (Baycol), diclofenac (Voltaren), felbamate (Felbatol), fenofibrate (TriCor), fluvastatin (Lescol), gemfibrozil (Lopid), isoniazid, itraconazole, (Sporanox), ketoconazole (Nizoral), leflunomide (Arava), lovastatin (Mevacor), methotrexate (Rheumatrex), nevirapine (Viramune), niacin, nitrofurantoin (Macrodantin), pioglitazone (Actos), pravastatin (Pravachol), pyrazinamide, rifampin (Rifadin), ritonavir (Norvir), rosiglitazone (Avandia), simvastatin (Zocor), tacrine (Cognex), tamoxifen, terbinafine (Lamisil), valproic acid, and zileuton (Zyflo).

Likelihood Likely Evidence B
Nephrotoxic Drugs

Siberian cocklebur can adversely affect the kidney. Theoretically, combining Siberian cocklebur with potentially nephrotoxic drugs might have additive harmful effects on kidney function.
Some potentially nephrotoxic drugs include cyclosporine (Neoral, Sandimmune); aminoglycosides including amikacin (Amikin), gentamicin (Garamycin, Gentak, others), and tobramycin (Nebcin, others); nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen (Advil, Motrin, Nuprin, others), indomethacin (Indocin), naproxen (Aleve, Anaprox, Naprelan, Naprosyn), piroxicam (Feldene); and numerous others.

Xanthium full monograph & interactions

Magnolia2 drug types · 351 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, magnolia might have additive effects and increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro research shows that the chemicals magnolol and honokiol, isolated from magnolia bark, inhibit platelet aggregation that is experimentally induced by collagen and arachidonic acid. However, they do not inhibit platelet aggregation that is induced by adenosine diphosphate, platelet-activating factor, or thrombin. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, concomitant use of large doses of magnolia bark and CNS depressants might have additive effects.
In vitro and animal research shows that constituents extracted from magnolia bark, especially honokiol and magnolol, have sedative effects. These effects may be due to the inhibition of catecholamine release and modulation of gamma-aminobutyric acid-A (GABA-A) receptors.

Likelihood Possible Evidence D
Magnolia full monograph & interactions

Angelica1 drug type · 186 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

In vitro research shows that ashitaba extract inhibits cytochrome P450 (CYP) 1A2. Theoretically, concomitant use of ashitaba with CYP1A2 substrates might decrease the clearance of these substrates and increase the risk for adverse effects. However, this interaction has yet to be reported in humans. Until more is known, use with caution.

Likelihood Possible Evidence D
Angelica full monograph & interactions

Forsythia2 drug types · 123 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking forsythia with anticoagulant or antiplatelet drugs might increase the risk of bleeding due to decreased platelet aggregation. Forsythia might reduce platelet aggregation by inhibiting platelet activating factor. Some of these drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Unlikely Evidence D
Azithromycin (Zithromax)

Theoretically, taking forsythia with azithromycin might increase the risk of adverse effects. Animal research in rats shows that taking a single dose of forsythia with azithromycin decreases the clearance and increases the area under the curve of both forsythiaside, a constituent of forsythia, and azithromycin. The mechanism of this interaction is not well understood.

Sinus Relief by L.A. Naturals: Common Questions

Does Sinus Relief by L.A. Naturals interact with any medications?
Yes. Based on its ingredients, Sinus Relief has a known interaction with 1,361 medications, including 662 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sinus Relief contains 10 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 during pregnancy or while breastfeeding?
No. Red Peony is marked possibly unsafe in pregnancy and unsafe while breastfeeding. Forsythia, Angelica, Magnolia, Schizonepeta, and Chrysanthemum all lack adequate safety data in both periods, and their labels advise against use. Xanthium is regarded as likely unsafe in both pregnancy and breastfeeding. Talk with your doctor before considering this product if you're pregnant or nursing.
What's Xanthium, and why is it such a concern?
Xanthium is Siberian cocklebur, an herb that has caused serious poisoning cases. It can damage your liver and kidneys, cause dangerously low blood sugar, and trigger heart rhythm problems and bleeding. It's one of the reasons you absolutely must check this product with your pharmacist before taking it, especially if you have diabetes or liver/kidney disease.
Can I take this if I'm on birth control?
Possibly not without checking first. Red Peony has estrogenic activity and may theoretically interfere with how hormonal birth control works. Talk with your doctor or pharmacist about whether this product is safe to use alongside your specific contraceptive.
Does this actually help with sinus symptoms?
The evidence isn't clear. Most of the active ingredients — Red Peony, Forsythia, Angelica, Chrysanthemum, Schizonepeta — have insufficient reliable evidence to show they work for the conditions they're traditionally used for. We simply don't have enough research yet to say this blend is effective.
What side effects can these herbs cause?
Most common are gastrointestinal complaints from peony: nausea, diarrhea, stomach bloating, and loss of appetite. Chrysanthemum can cause allergic reactions and contact dermatitis in sensitive people. Xanthium carries the most serious risks — severe vomiting, low blood sugar, heart arrhythmia, and liver damage. Stop and seek medical attention if you experience any of these.
Can I take this with my other supplements?
That depends on what you're taking. Because these ingredients affect liver enzymes that process many drugs and supplements, interactions are possible. Bring your full list of medications and supplements to your pharmacist before starting this product.
