HelloPharmacist Scorecard of Tree Country Allergy & Sinus by WishGarden

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.

From our pharmacy team — supplement deep dive

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 Extract Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Tree Country Allergy & Sinus contains 7 active ingredients in a liquid extract form. The blend includes orange peel, yerba santa leaf, elderflower, echinacea root, yerba mansa root, nettles leaf, and horseradish root — each chosen for traditional use in supporting respiratory and sinus health.

The product is suspended in a base of Rocky Mountain artesian spring water, vegetable glycerin, and organic, gluten-free alcohol.

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: Soothe irritated sinus and respiratory tissues.
  • We looked for evidence on: Allergic rhinitis (hay fever), Asthma, Common cold, Gingivitis, Influenza, Respiratory tract infections — and 4 related terms.
  • The closest evidence on file: Horseradish is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Horseradish is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs).
  • Also on file: Stinging Nettle is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever), Asthma, Gingivitis, Urinary tract infections (UTIs).

The evidence we hold does not establish that this product is effective for any specific condition. Orange peel extract, echinacea, nettles, and horseradish all have effectiveness ratings of insufficient reliable evidence for their traditionally used purposes — including allergy support, respiratory infections, and related complaints.

That doesn't mean they don't work; it means rigorous clinical trials backing them up aren't in our database. Talk with your pharmacist or doctor about what the research actually shows for your particular goal.

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 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.

Orange peel extract is safe in food amounts, but concentrated extracts call for caution because they haven't been thoroughly studied. Echinacea is generally well tolerated short-term but may trigger allergic reactions, especially in people sensitive to ragweed and related plants; rare cases of liver inflammation have been reported.

Nettles leaf is generally well tolerated as directed, though liver injury cases exist in the literature. Horseradish is safe in food amounts but large doses can cause stomach upset, vomiting, or in rare cases, fainting.

Yerba Santa and yerba mansa have limited human safety data; use caution and discuss with your healthcare provider. For pregnancy: orange peel extract is likely safe; echinacea is possibly safe; nettles and horseradish should be avoided (nettles are likely unsafe); yerba santa and yerba mansa lack adequate data — talk with your doctor.

For breastfeeding, nettles and horseradish are likely unsafe, and yerba santa and yerba mansa lack reliable safety data.

Echinacea 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

Elder flower extract2 drug types · 644 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, taking American elder might increase levels of CYP3A4 substrates.
In vitro research shows that American elder inhibits CYP3A4 enzymes.

Likelihood Possible Evidence D
Lithium

Theoretically, American elder might reduce excretion and increase levels of lithium.
American elder is thought to have diuretic properties. Theoretically, American elder might reduce the excretion of lithium, increasing serum levels.

Likelihood Probable Evidence D

Yerba Mansa root extract1 drug type · 248 drugs

Cns Depressants

Theoretically, concomitant use might cause additive or prolonged sedative effects.

Likelihood Probable Evidence D

Orange peel extract7 drug types · 246 drugs

Celiprolol (Celicard)

Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.
A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP). Recommend separating drug administration and consumption of sweet orange by at least 4 hours.

Likelihood Likely Evidence B
Ivermectin (Stromectol, Others)

Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.
A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females.

Likelihood Likely Evidence B
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP. For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90%. Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours.

Likelihood Likely Evidence B
Pravastatin (Pravachol)

Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.
A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice. Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.

Likelihood Likely Evidence B
Fexofenadine (Allegra)

Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.
Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72%. In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31%. Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP). Recommend separating drug administration and consumption of sweet orange by at least 4 hours.

Likelihood Likely Evidence B
P-Glycoprotein Substrates

Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.
Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates. In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium-fortified sweet orange juice might reduce quinolone absorption.
Calcium binds to quinolones in the gut. Theoretically, the calcium in certain fortified orange juices can also bind to quinolone antibiotics and reduce their absorption and levels.

Likelihood Possible Evidence D

Nettles leaf extract4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Likelihood Possible Evidence D

Horseradish root extract1 drug type · 16 drugs

Thyroid Hormone

Theoretically, horseradish might interfere with the effects of thyroid hormone.
Horseradish and other members of the cabbage and mustard family are associated with depressed thyroid function.

Likelihood Possible Evidence D

Yerba Santa leaf extract1 drug type · 1 drug

Lithium

Yerba santa is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, yerba santa might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Tree Country Allergy & Sinus by WishGarden: Common Questions

Does Tree Country Allergy & Sinus by WishGarden interact with any medications?
Yes. Based on its ingredients, Tree Country Allergy & Sinus has a known interaction with 1,195 medications, including 48 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Tree Country Allergy & Sinus 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.
Is this safe to take while I'm pregnant or breastfeeding?
It depends on the ingredient. Orange peel extract is likely safe in pregnancy. Echinacea is possibly safe. Nettles and horseradish should be avoided — they're likely unsafe while breastfeeding, and nettles are likely unsafe in pregnancy. Yerba santa and yerba mansa lack enough safety data to say either way. Talk with your doctor or pharmacist for personalized advice based on your situation.
Can this cause allergic reactions?
Yes. Echinacea can trigger allergic reactions, especially if you're sensitive to ragweed or related plants (daisies, chrysanthemums, marigolds). Horseradish can also cause allergic reactions and skin irritation. If you have plant allergies or atopy, mention this to your pharmacist before taking it.
What are the common side effects?
Echinacea may cause abdominal pain, constipation, diarrhea, heartburn, nausea, vomiting, rashes, or stomach upset. Nettles may cause constipation or diarrhea. Horseradish in large amounts can cause gastrointestinal upset or vomiting. Most users experience no side effects, but these are the ones reported.
Does this actually work for allergies or sinus problems?
We don't have clinical evidence in our data showing it's effective for those purposes. The ingredients have traditional uses, but rigorous trials establishing their benefit aren't on file. Talk with your pharmacist about what research exists outside our database and what might work best for you.
Why do I need to wait 4 hours between taking this and certain medications?
Orange peel extract can block the absorption of some medications if you take them at the same time. Spacing doses 4 hours apart helps reduce that interference so your drug gets absorbed properly and works as intended.
Is this product free of fillers and additives?
No. In addition to the 7 active herbal ingredients, it contains rocky mountain artesian spring water, vegetable glycerin, and organic, gluten-free alcohol as inactive ingredients. These are the carrier and preservation ingredients in the liquid formula.
