HelloPharmacist Scorecard of Asparagus Extract by Enzymatic Therapy

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

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: asparagus (Asparagus officinalis) rhizome extract — the underground stem of the asparagus plant in concentrated form. The inactive ingredients are cellulose (a plant fiber), a vegetable polysaccharide capsule, and magnesium stearate (a flow agent).

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: potent detoxifier supporting urinary tract function.
  • We looked for evidence on: Urinary tract infections (UTIs), urinary tract health, detoxification, fluid retention.
  • The closest evidence on file: Asparagus is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs) (Natural Medicines).

The evidence for asparagus extract isn't established in our data. Effectiveness ratings for acne, cancer, constipation, high blood pressure, intestinal parasites, and kidney stones all show insufficient reliable evidence — meaning there isn't enough solid research yet to say whether it works for any of these conditions.

The evidence, ingredient by ingredient Asparagus

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.

Asparagus as a food is generally well tolerated, but concentrated extracts like this one are less studied. Safety data advises caution with medicinal doses of asparagus extract — they haven't been proven safe the way the food has.

Allergic reactions are possible, especially in people sensitive to the lily family (onions, garlic, leeks, chives); symptoms can range from itchy eyes and a runny nose to hives, difficulty swallowing, difficulty breathing, and in rare cases anaphylaxis. One clinical trial of a combination product containing asparagus root caused side effects — constipation, belly pain and bloating, nausea, dry mouth, gallbladder complaints, and gout — in a portion of participants, though it's unclear whether asparagus or the other ingredient was responsible.

Side effects, ingredient by ingredient Asparagus

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 — Asparagus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 76 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 taking this product, check your medications if you take lithium (a mood stabilizer) or diuretic drugs (water pills for blood pressure or fluid buildup). Both have Moderate-severity interactions with asparagus extract.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is for people interested in asparagus extract, but the evidence it works for any specific condition isn't clear yet. If you take lithium or diuretic medications, you'll need to check with your pharmacist first — don't start without clearing it.

Because the safety data for medicinal doses is limited, talk to your pharmacist before you begin.

Asparagus Extract by Enzymatic Therapy: Common Questions

Does Asparagus Extract by Enzymatic Therapy interact with any medications?
Yes. Based on its ingredients, Asparagus Extract has a known interaction with 76 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Asparagus Extract 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.
Does asparagus extract actually work for anything?
The evidence in our data isn't clear. We have effectiveness ratings for acne, cancer, constipation, high blood pressure, intestinal parasites, and kidney stones — all showing insufficient reliable evidence. That means there's not enough solid research to say whether it works for any of these yet.
Is this safe if I'm pregnant or breastfeeding?
The data on file gives conflicting signals for pregnancy — one source says Likely Safe, another says Possibly Unsafe. For breastfeeding, Likely Safe is noted, but there isn't enough data to be certain. Talk with your doctor or pharmacist about what's right for you in your situation.
Can I have an allergic reaction to asparagus extract?
Yes, if you're sensitive to asparagus or other plants in the lily family (onions, garlic, leeks, chives), you can have allergic reactions — anything from itchy eyes and a runny nose to hives, throat tightness, trouble breathing, or rarely anaphylaxis. There have also been reports of skin reactions that return the same way each time you take it.
What's the difference between eating asparagus and taking this extract?
Eating asparagus as food is well tolerated and fine. This product is a concentrated extract in medicinal doses, which hasn't been studied as thoroughly. The safety data advises caution with medicinal amounts, so this isn't the same as just eating asparagus on your plate.
What inactive ingredients are in this capsule?
The inactive ingredients are cellulose, a vegetable polysaccharide capsule, and magnesium stearate. These are standard excipients — fillers and binders that hold the capsule together.
