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 Black Radish dried root liquid extract. The extract is prepared in a menstruum (a liquid preparation base).

Black Radish has been used traditionally to support biliary (liver and bile duct) function, though the evidence for those uses isn't established.

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 for Black Radish isn't well established for the uses it's typically marketed for. We hold insufficient reliable evidence to rate it for biliary disorders or diabetes.

While animal research does show that radish can lower glucose levels in rats, we don't have solid human trial data showing it works as a diabetes treatment.

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 food and is generally well tolerated in normal dietary amounts. However, concentrated supplements like this one aren't as well studied.

Raw sprouts should be unwashed because of food-borne illness risk. Large amounts of radish may irritate your stomach and cause mild indigestion.

A rare case of allergic reaction (throat tightness and hives) to radish has been reported, though this is uncommon. There isn't enough data on file to know whether this product is safe during pregnancy or breastfeeding.

Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding.

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.

Black Radish is a traditional herbal extract that's generally well tolerated in the amounts found in food, but safety of concentrated supplements isn't well studied. The key concern is if you take antidiabetes medication — the extract may lower your blood sugar further, so check with your doctor or pharmacist before adding it.

If you're pregnant, breastfeeding, or have digestive concerns, talk it over with your healthcare provider first.

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.

Black Radish by Herbal Terra: Common Questions

Does Black Radish by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Black 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?
Black 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.
Will Black Radish actually help with blood sugar or liver health?
The evidence isn't established yet. While animal research does show that radish can lower glucose levels, we don't have solid human trial data to say it works for diabetes or biliary disorders. It's a traditional use, but that's different from proven.
What could happen if I take this with my antidiabetes medication?
Animal research shows radish extract can reduce blood glucose, so there's a theoretical risk of low blood sugar (hypoglycemia) when you combine it with antidiabetes drugs. This is why you need to check with your doctor or pharmacist before starting it.
Is Black Radish safe to take long-term?
Radish is safe in normal food amounts, but long-term safety of concentrated supplements like this one isn't well studied. Stick to the label dose and talk with your pharmacist if you plan to use it regularly.
What side effects should I watch for?
Most people tolerate it well, but large amounts may cause stomach irritation or mild indigestion. A rare allergic reaction (throat tightness and hives) has been reported. Stop if you notice any of these and talk to your pharmacist.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough data on file to know either way. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding — they know your full health picture.
