HelloPharmacist Scorecard of Oralmat by Allergy Research Group

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.

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Oralmat is a liquid supplement with 2 active ingredients: stevia extract and fresh Secale cereale grass extract. Stevia is a natural sweetener derived from the stevia plant; the extract contains steviol glycosides, the compounds responsible for its sweetness and potential biological effects.

The product also contains several inactive ingredients (purified water, ethanol, sorbitol, propylene glycol, ascorbic acid, polysorbate 20, benzyl alcohol, and lemon essence) that serve as solvents, preservatives, and flavoring.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Stevia product and its label doesn't state a use — see Stevia's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence on stevia extract for diabetes, high blood pressure, and weight loss is insufficient to establish whether it works for these purposes in humans. While preliminary research suggests stevia extract might reduce blood sugar levels after meals in people with type 2 diabetes, other studies have not confirmed a significant blood pressure-lowering effect.

We don't hold established effectiveness data for Secale cereale grass extract.

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Purified stevia in typical food amounts is generally well tolerated. However, the safety of whole-leaf stevia or high-dose supplements like Oralmat is not well studied, so caution is warranted.

Most people who take stevia experience mild side effects — abdominal bloating, dizziness, headache, muscle pain (myalgia), nausea, and numbness — but these tend to resolve after the first week. Rare allergic reactions have been reported.

Pregnancy and lactation safety data are not on file for stevia extract in supplement doses.

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?
  • 1 of the 1 matched ingredient can interact with medications — Stevia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 259 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.

Check with your doctor or pharmacist before taking Oralmat if you take lithium (Moderate interaction risk), any blood pressure medication, or any diabetes drug (both Minor interaction risk). No interactions are documented for the Secale cereale grass extract we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Oralmat may be worth considering if you're interested in a stevia-based supplement, but only if you don't take lithium, blood pressure medication, or diabetes drugs — or if you clear any of these with your own doctor or pharmacist first. If you're pregnant or breastfeeding, talk with your healthcare provider before starting, since safety data for supplement-dose stevia are limited.

Stevia extract3 drug types · 259 drugs

Lithium

Theoretically, stevia might decrease clearance and increase levels of lithium.
Animal research suggests that stevia extracts might have diuretic activity. Theoretically, increased reabsorption of lithium along with sodium might reduce excretion and increase levels of lithium.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, stevia might increase the risk for hypoglycemia when combined with antidiabetes drugs.
Preliminary clinical research in patients with type 2 diabetes suggests that taking a single dose of stevia extract 1000 mg reduces postprandial blood glucose levels when taken with a meal. However, other clinical research in patients with type 1 or type 2 diabetes suggests that taking stevioside 250 mg three times daily does not significantly affect blood glucose levels or glycated hemoglobin (HbA1C) after three months of treatment.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, combining stevia or stevia constituents with antihypertensive agents might increase the risk of hypotension.
Stevia extract and stevioside might lower blood pressure in patients with hypertension. However, other clinical research suggests that stevioside does not significantly lower blood pressure in patients with hypertension.

Oralmat by Allergy Research Group: Common Questions

Does Oralmat by Allergy Research Group interact with any medications?
Yes. Based on its ingredients, Oralmat has a known interaction with 259 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Oralmat contains 2 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.
What is stevia extract and why is it in this product?
Stevia extract is a natural sweetener made from the stevia plant. It contains steviol glycosides, which give stevia its sweet taste and may have effects on blood sugar and blood pressure — though the evidence isn't strong enough yet to say it works reliably for those purposes.
Could Oralmat lower my blood sugar if I'm on diabetes medication?
Possibly. Some research suggests stevia extract can lower blood sugar after meals, and if combined with diabetes medication, it might increase the risk of low blood sugar (hypoglycemia). If you take any diabetes drug, check with your doctor or pharmacist before starting Oralmat.
What side effects might I experience?
The most common ones are abdominal bloating, dizziness, headache, muscle pain, nausea, and numbness. Most of these resolve after the first week. Allergic reactions are rare but possible.
Is Oralmat safe to take while pregnant or breastfeeding?
We don't have enough safety data on supplement-dose stevia for pregnancy or breastfeeding. Talk with your doctor or pharmacist about whether Oralmat is right for you.
Why does the interaction count say 259 medications?
That's the total number of individual medications affected by stevia's documented interactions across all three drug categories — lithium, blood pressure medications, and diabetes drugs. The interaction isn't unique to Oralmat; it's a property of stevia extract itself.
