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
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.

Lai Fu Zi contains one active ingredient: Raphanus sativus seed extract in dry form, commonly known as radish seed extract. The liquid formula also includes alcohol, water, and glycerin as inactive ingredients to carry 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 for radish seed extract is not yet established for the uses listed — biliary disorders and diabetes both carry a rating of insufficient reliable evidence. That means we don't have enough human data yet to say whether it works for these purposes.

Animal studies suggest radish may affect blood sugar, but human trials are lacking.

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. The safety data cautions that concentrated supplements haven't been well studied, so stick to typical food portions if you're using this product.

Unwashed raw sprouts should be avoided. Rare allergic reactions have been reported, including throat tightness and hives.

Large amounts may cause mild gastrointestinal irritation or indigestion. Pregnancy and lactation safety data is not on file for radish — talk with your doctor or pharmacist about whether this product is right for you during pregnancy or while breastfeeding.

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.

Check any antidiabetes drugs (blood sugar medications) before starting this product. Radish extract may increase the risk of low blood sugar when combined with these medications.

Your blood sugar may need closer monitoring, or your dose may need adjustment.

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 single-ingredient radish seed extract used in herbal practice, though human evidence for its effectiveness isn't yet established. If you take any blood sugar medication, check with your pharmacist first — radish may lower blood sugar further.

Generally well tolerated in food amounts, but concentrated supplement safety hasn't been fully studied.

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 this if I'm on diabetes medication?
Not without checking first. Radish extract may lower blood sugar further, raising your risk of hypoglycemia (low blood sugar). Talk to your pharmacist or doctor — they may want to monitor your levels more closely or adjust your dose.
Is radish seed extract safe to take every day?
Radish is safe in normal food amounts. But concentrated supplements like this one haven't been well studied long-term, so we don't have solid data on daily use. Talk to your pharmacist about what's right for you.
Does this actually work for blood sugar or digestion?
The evidence isn't there yet — both uses carry a rating of insufficient reliable evidence. Animal studies hint that radish may affect blood glucose, but human trials are lacking. We can't say it works based on the data we have.
What should I watch out for when taking it?
Allergic reactions are rare but possible — stop and seek help if you feel throat tightness or hives. Large amounts may upset your stomach. Since this is a concentrated supplement, use it as directed on the label and don't exceed recommended doses.
Is it safe during pregnancy or breastfeeding?
We don't have safety data for radish supplements in pregnancy or lactation. Talk with your doctor or pharmacist for personalized advice — they can help you weigh the risks and benefits for your situation.
