HelloPharmacist Scorecard of Stevia by Herbal Terra

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

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: certified organic stevia (Stevia rebaudiana) dried leaf liquid extract. Stevia is a non-caloric sweetener derived from the stevia plant leaf.

The product also includes menstruum as an inactive ingredient — the liquid base used to extract and deliver the stevia.

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 for stevia's effectiveness isn't established in our data. The product facts note insufficient reliable evidence to rate it for diabetes, hypertension, and obesity.

While some preliminary research suggests stevia extract may reduce blood sugar spikes after meals in people with type 2 diabetes, other studies haven't confirmed the effect, and we don't have enough consistent data to say whether it works for any of these uses.

The evidence, ingredient by ingredient Stevia

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 sweeteners at food amounts are generally recognized as safe. However, this is a whole-leaf supplement extract at higher doses than typical food use, and safety data for these amounts are limited — the facts advise caution.

The most common side effects are mild: abdominal bloating, dizziness, headache, muscle pain, nausea, and numbness. Most of these resolve after the first week.

Allergic reactions are rare but possible. There isn't enough pregnancy and lactation safety data on file for stevia supplements, so talk to your doctor or pharmacist before taking this if you're pregnant or breastfeeding.

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.

Before you take this stevia supplement, check with your doctor or pharmacist if you take lithium (moderate interaction risk), blood pressure medications, or antidiabetes drugs (both minor). These are the medication types we have documented interactions for with stevia.

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.

Stevia by Herbal Terra is a natural sweetener, but at supplement doses it hasn't been proven to help with blood sugar, blood pressure, or weight. More importantly, if you take lithium, blood pressure meds, or diabetes medications, you need to check with your doctor or pharmacist first — the interactions are real and could affect how your drugs work.

For most other people, it's likely tolerated, but there's limited safety data at high doses.

certified organic Stevia (Stevia rebaudiana) dried leaf liquid 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.

Stevia by Herbal Terra: Common Questions

Does Stevia by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Stevia 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?
Stevia contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 use this stevia if I take blood pressure medicine?
Not without checking first. Stevia might lower blood pressure on its own, and combining it with your medication could drop your pressure too much. Talk to your doctor or pharmacist before you start.
What are the most common side effects?
Bloating, dizziness, headache, muscle pain, nausea, and numbness are the ones people report most. Most go away after the first week. Allergic reactions are rare.
Is this safe to use while pregnant or breastfeeding?
We don't have enough safety data on supplement-dose stevia to say either way. Talk with your doctor or pharmacist about whether it's right for you during pregnancy or while nursing.
Will stevia help me lose weight or control my blood sugar?
The evidence isn't established. Some early research hints it might help with blood sugar spikes, but other studies don't confirm it, and we don't have reliable data showing it works for weight or diabetes.
What's the difference between this and stevia I buy as a food sweetener?
Food-amount stevia sweeteners are generally recognized as safe. This supplement is a concentrated whole-leaf extract at higher doses, and safety at these amounts isn't well studied — that's why the facts advise caution.
