HelloPharmacist Scorecard of Radish by Hawaii Pharm

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 radish extract in a liquid form. Radish extract concentrates the compounds naturally found in the radish root.

The liquid also contains vegetable palm glycerin and alcohol as inactive ingredients (used to preserve and deliver the extract).

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 Radish product and its label doesn't state a use — see Radish'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 radish for biliary (bile duct and gallbladder) disorders and diabetes is insufficient—we don't have reliable data showing it works for either condition. While animal studies hint that radish may lower blood sugar, those results don't yet translate to solid proof in people.

If you're considering radish for a specific health concern, talk it over with your doctor to weigh what's known.

The evidence, ingredient by ingredient Radish

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.

Radish is widely eaten as a food and is generally well tolerated in normal dietary amounts. However, concentrated radish supplements haven't been studied thoroughly, and the product label cautions against unwashed raw sprouts.

Large amounts of radish may irritate your digestive tract and cause mild indigestion; one clinical trial using a multi-ingredient product containing radish reported indigestion, though it's unclear whether radish or another ingredient was responsible. A rare case of allergy to radish has been reported, with symptoms including throat tightness and generalized hives.

Pregnancy and lactation safety data isn't on file for radish; talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding.

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 — Radish.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

Antidiabetes drugs (including insulin and oral blood sugar–lowering medications) are the main concern—radish may theoretically increase the risk of low blood sugar when combined with them. Check your specific diabetes medications with your doctor or pharmacist before starting this product.

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.

Radish extract is a single-ingredient supplement generally well tolerated in food amounts, but concentrated forms are less studied. The main concern is a moderate interaction with diabetes medications, which can theoretically lower blood sugar too much.

If you take any blood sugar–lowering drugs, check your exact medications with your doctor or pharmacist before you start. For other uses, evidence is still insufficient to confirm it works.

Antidiabetes Drugs

Theoretically, radish might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that radish extract, juice, and sprouts can reduce glucose levels. Animal research also shows that radish root juice 300 mg/kg reduces fasting and postprandial blood glucose in a rat model of diabetes, with effects similar to glibenclamide.

Radish by Hawaii Pharm: Common Questions

Does Radish by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Radish has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Radish 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 take this if I'm on diabetes medication?
Not without checking first. Radish extract may theoretically increase the risk of low blood sugar (hypoglycemia) when combined with antidiabetes drugs like insulin or metformin. Talk with your doctor or pharmacist about your specific medications before you start.
Will radish extract help my blood sugar?
Animal research suggests radish may lower blood sugar, but we don't have reliable evidence that it works in people. The data isn't established enough to recommend it for diabetes. Your doctor is the best source for guidance on managing your blood sugar.
Is this supplement safe to take?
Radish is safe in normal food amounts. Concentrated supplements haven't been well studied, so there's some caution. Large amounts may irritate your digestive tract and cause mild indigestion. A rare allergy to radish has been reported with throat tightness and hives.
What does the alcohol in this product do?
The alcohol (and vegetable palm glycerin) are inactive ingredients used to preserve and deliver the radish extract. They're not therapeutic ingredients themselves.
Is this safe during pregnancy or breastfeeding?
Safety data for radish during pregnancy and lactation isn't on file. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding—they can give you personalized advice.
Can I be allergic to radish?
Radish allergy is rare, but one case has been reported with symptoms of throat tightness and generalized hives. Stop use and seek medical attention if you experience any signs of an allergic reaction.
