HelloPharmacist Scorecard of Lai Fu Zi 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

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.

Lai Fu Zi contains one active ingredient: certified organic radish seed liquid extract. The extract is made from Raphanus sativus, the common radish plant.

It's prepared as a concentrated liquid using menstruum (a liquid solvent used in herbal extraction).

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 we hold isn't enough to rate this extract for biliary disorders or diabetes. While animal studies suggest radish can lower blood sugar, we don't have reliable human trial data to say whether this product is effective for any specific condition.

That doesn't mean it doesn't work — just that the data we hold doesn't establish it yet.

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 amounts. However, concentrated supplements like this one are less well studied than the food itself.

Large amounts of radish may irritate your stomach lining and cause mild indigestion. A rare allergy to radish has been reported, with symptoms including throat tightness and a rash.

The product facts don't include enough data to say whether this extract is safe during pregnancy or breastfeeding — talk with your pharmacist or doctor for personalized advice if you're pregnant, nursing, or planning to be.

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.

Check your exact antidiabetes medications (insulin, metformin, sulfonylureas, and others) with the search tool below before taking this product. Radish theoretically raises your risk of low blood sugar when combined with these drugs.

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.

Lai Fu Zi is a radish seed extract that might lower blood sugar. If you take diabetes medications, check with your pharmacist before starting it.

If you're not on blood-sugar medications and have no allergy to radish, it's generally well tolerated — but the evidence for what it actually does isn't established yet.

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.

Lai Fu Zi by Herbal Terra: Common Questions

Does Lai Fu Zi by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Lai Fu Zi 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?
Lai Fu Zi 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 Lai Fu Zi if I'm on insulin or a diabetes pill?
You need to check with your pharmacist or doctor first. Because radish can lower blood sugar, there's a theoretical risk it could make your blood sugar too low when you're on diabetes medications. Your doctor may still say yes — but they need to know about it so they can monitor you or adjust your dose.
What's actually in this product?
It's a concentrated liquid extract made from organic radish seeds. The extract is prepared using a liquid solvent called menstruum.
Is radish safe to eat if I'm using this supplement?
Radish as food — like in salads — is generally safe and widely eaten. The caution here is about concentrated supplements like this extract, which haven't been studied as much. Normal food amounts are likely fine, but we don't have strong safety data for concentrated radish supplements.
Can this cause an allergic reaction?
True allergy to radish is very rare, but it has been reported. Symptoms included throat tightness and a rash. If you've never had radish before, start small and watch for any throat or skin symptoms.
Will this upset my stomach?
Large amounts of radish may irritate your stomach and cause mild indigestion. One clinical study using a combination product that included radish reported mild indigestion, though it's unclear whether radish alone caused it or if other ingredients in that product were responsible.
Is this safe during pregnancy or breastfeeding?
We don't have enough data to say whether this radish extract is safe during pregnancy or breastfeeding. Talk with your pharmacist or doctor about your individual situation before taking it.
