HelloPharmacist Scorecard of Elderberry-Thyme Syrup by True Botanica

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 2 of its 15 active ingredients.
  • “A proprietary mix of” is a proprietary blend — the label gives one combined amount (7.30 Gram(s)) without saying how much of each component you get.

This 14-ingredient syrup contains sodium, potassium, citric acid, xylitol, and thyme (in three forms: thyme oil, thyme herb, and thyme powder) as active components, alongside elderberry extract, oregano (Origanox), and usnea oil. The remaining ingredients—sucrose, water, citric acid, raspberry flavor, and acacia—serve as sweeteners, solvents, flavoring, and texture agents.

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: immune system support, sore throat and cough.
  • We looked for evidence on: Common cold, Cough, Upper respiratory tract infection (URTI), Lower respiratory tract infections, Respiratory tract infections, Pharyngitis — and 4 related terms.
  • The closest evidence on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Rhinosinusitis, Upper respiratory tract infection (URTI), Lower respiratory tract infections.
  • Also on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Upper respiratory tract infection (URTI), Cough.

We hold no effectiveness data for this specific product formula. For individual ingredients, the evidence is sparse: elderberry extract, thyme, oregano, and usnea all show insufficient reliable evidence for their claimed uses (respiratory infections, cough, bronchitis, and others).

Citric acid and xylitol also lack established evidence for most of their studied uses, though xylitol is likely effective for dental cavities. Sodium and potassium are essential minerals but are not intended as medicinal treatments in supplemental form.

The evidence, ingredient by ingredient Sodium Potassium Black Psyllium Elderberry Citric Acid Xylitol Gum Arabic Thyme

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 10 of the 10 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 10 of 10.
  • General safety write-ups exist for 10 of 10.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

When used in normal food amounts, the ingredients in this syrup are generally well tolerated. Sodium is essential in small amounts, but too much is linked to high blood pressure and heart strain — normal dietary sodium is fine, but avoid supplements or very high intake without medical advice.

Potassium from food is generally safe, though supplements can cause dangerously high blood levels in some people, especially those with kidney disease. Thyme, elderberry (when properly prepared from ripe fruit), and oregano are generally safe in food amounts; however, raw or unripe elderberries and concentrated thyme or oregano oils may carry higher risks.

Usnea raises concern — topical use is generally tolerated, but oral usnic acid (a usnea component) has been linked to liver damage. Xylitol may cause digestive upset at high doses and is highly toxic to dogs.

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?
  • 7 of the 10 matched ingredients can interact with medications — Black Psyllium, Gum Arabic, Elderberry, Oregano, Thyme, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 2,174 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 using this product, check with your pharmacist if you take blood pressure medications (especially ACE inhibitors, ARBs, or antihypertensives), blood thinners or antiplatelet drugs, diabetes medications, potassium-sparing diuretics, immunosuppressants, cancer drugs like pazopanib, or estrogen replacement therapy. These are the drug types with documented moderate interactions.

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 syrup may be worth considering if you're looking for a thyme-elderberry combination, though we have no strong evidence it works for any specific condition. If you take blood pressure medications, blood thinners, diabetes drugs, kidney medications, or immunosuppressants, talk to your pharmacist before starting — the sodium, potassium, and other ingredients may interfere.

Those with kidney disease or on strict dietary sodium/potassium limits should check with their doctor first.

Each ingredient & the kinds of drugs it affects

For each ingredient in Elderberry-Thyme Syrup with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Likelihood Possible Evidence B

Acacia2 drug types · 2,022 drugs

Amoxicillin (Amoxil, Trimox)

Gum arabic can reduce the absorption of amoxicillin.
A small study in healthy volunteers shows that taking amoxicillin and gum arabic concurrently significantly reduces the absorption of amoxicillin. Separate doses of amoxicillin from gum arabic by at least 2 hours.

Likelihood Probable Evidence B
Oral Drugs

Theoretically, gum arabic can alter the absorption of oral drugs due to its fiber content.
Gum arabic has been used as a suspending osmotic agent in drug formulations. It might improve bioavailability of water-insoluble drugs like naproxen, but reduce absorption of polar drugs like amoxicillin. To avoid changes in absorption, take gum arabic 30-60 minutes after oral medications.

Likelihood Possible Evidence B

Thyme Oil4 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

Origanox2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, oregano might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that aristolochic acid isolated from oregano leaves has antithrombin activity. It has also been reported that oregano oil inhibits arachidonic acid-induced, and ADP-induced, platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, oregano might increase the risk for hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research shows that oregano extracts might lower blood glucose levels.

Likelihood Possible Evidence D

Sodium7 drug types · 205 drugs

Antihypertensive Drugs

Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.

Likelihood Probable Evidence A
Corticosteroids

Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.

Likelihood Possible Evidence D
Didanosine (Videx)

Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.

Likelihood Probable Evidence C
Lithium

Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.

Likelihood Probable Evidence B
Sodium Phosphates

Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Sodium-Containing Drugs

Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Tolvaptan (Samsca)

Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Likelihood Probable Evidence C

Elderberry Extract2 drug types · 121 drugs

Immunosuppressants

Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor.

Likelihood Possible Evidence B
Pazopanib (Votrient)

Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 4 weeks for soft-tissue sarcoma developed severe nausea, loose stools, and elevated alanine transaminase and aspartate transaminase levels and was diagnosed with grade 3 liver injury. The patient reported taking elderberry supplements for 2 years, dose unspecified, and was also taking a multivitamin and a calcium supplement. The patient's symptoms and liver enzyme levels improved upon discontinuation of pazopanib and all supplements. Pazopanib treatment was re-initiated, at a lower dose, with no further evidence of liver injury. It was unclear in this case report if the elderberry supplements were derived from the berry, the flower, or the combination.

Likelihood Possible Evidence D

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Elderberry-Thyme Syrup by True Botanica: Common Questions

Does Elderberry-Thyme Syrup by True Botanica interact with any medications?
Yes. Based on its ingredients, Elderberry-Thyme Syrup has a known interaction with 2,173 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Elderberry-Thyme Syrup contains 17 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?
Sodium and potassium from food amounts are likely fine, and thyme is rated likely safe. However, elderberry and oregano lack enough safety data — the facts advise avoiding elderberry supplements in pregnancy. Talk to your doctor or pharmacist for personalized advice, since pregnancy needs are individual.
Is this safe while breastfeeding?
Sodium, potassium, and thyme appear likely safe at food amounts. Elderberry, oregano, and especially usnea have insufficient safety data for breastfeeding — the facts advise avoiding them. Check with your doctor or pharmacist before using this while nursing.
Can this cause stomach upset?
Yes. Thyme can cause diarrhea, nausea, vomiting, and heartburn. Oregano may cause gastrointestinal upset. Xylitol, especially at higher doses, can cause diarrhea, flatulence, and abdominal discomfort. If you notice these symptoms, lower your dose or stop and contact your pharmacist.
What is usnea, and why is it in this?
Usnea is a lichen used traditionally for cough and other purposes, but the evidence is insufficient. The concern is its active compound, usnic acid, which has been linked to liver damage when taken by mouth — topical use is generally safer. This is worth discussing with your pharmacist before use.
Does this actually help with colds or cough?
The ingredients — elderberry, thyme, oregano, and usnea — all show insufficient reliable evidence for colds, cough, or respiratory infections in our data. This doesn't mean they don't work, just that solid evidence isn't established yet.
Is this safe for someone with high blood pressure?
Caution is needed. Sodium in this syrup can reduce how well blood pressure medications work, and potassium can interact with certain types (ACE inhibitors and ARBs). If you have high blood pressure or take blood pressure drugs, ask your pharmacist or doctor before starting.
