HelloPharmacist Scorecard of Dandelion Leaf by Herbalist & Alchemist

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 23, 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: fresh dandelion leaf extract. The liquid also holds distilled water and ethyl alcohol as inactive ingredients—the alcohol is a common preservative in herbal tinctures and extracts.

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: supports urinary tract function.
  • We looked for evidence on: Urinary tract infections (UTIs), Urinary tract health, Dysuria, Urinary frequency.
  • The closest evidence on file: Dandelion is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs) (Natural Medicines).

The evidence we hold on dandelion leaf doesn't establish that it works for the conditions listed—joint pain, tonsillitis, and postoperative swelling or pain all carry a rating of insufficient reliable evidence. That doesn't mean it doesn't help; it means the studies either aren't robust enough yet or aren't available in our data to make a confident call.

The evidence, ingredient by ingredient Dandelion

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.

Dandelion is generally well tolerated when used as food, but supplement-strength doses are less well studied. The most common side effects from taking it by mouth are diarrhea, heartburn, and stomach discomfort.

A small number of sensitive individuals have reported anaphylaxis (a severe allergic reaction), and allergic reactions including asthma and hay fever symptoms have been linked to dandelion pollen exposure. Because dandelion belongs to the ragweed family (Asteraceae), people with allergies to ragweed, chrysanthemums, marigolds, daisies, or related plants should be cautious.

The safety data on this product while breastfeeding is limited, so caution is advised—talk with your doctor or pharmacist before use. There is no rating on file for pregnancy safety; discuss it with your healthcare provider before taking it while pregnant.

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 — Dandelion.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 457 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 you take this product, ask your doctor or pharmacist to check your medications against these types: diabetes drugs (risk of low blood sugar), blood thinners and antiplatelet drugs (risk of bleeding), potassium-sparing diuretics, lithium, drugs broken down by the CYP1A2 liver enzyme, drugs processed through glucuronidation, and quinolone antibiotics. All carry moderate-severity interaction potential.

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.

Dandelion leaf extract may appeal to you if you're interested in herbal support, but the evidence for its effectiveness in the conditions listed isn't established yet in our data. The bigger consideration is that it interacts with a significant number of medications—especially diabetes drugs, blood thinners, potassium-sparing water pills, and lithium.

If you take any of these, or if you have allergies to ragweed or related plants, check with your doctor or pharmacist before starting.

fresh Dandelion leaf extract7 drug types · 457 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.

Likelihood Possible Evidence D
Lithium

Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.

Likelihood Possible Evidence D
Quinolone Antibiotics

Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.

Dandelion Leaf by Herbalist & Alchemist: Common Questions

Does Dandelion Leaf by Herbalist & Alchemist interact with any medications?
Yes. Based on its ingredients, Dandelion Leaf has a known interaction with 457 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Dandelion Leaf 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.
What is dandelion leaf extract used for?
The conditions listed in our data are joint pain, tonsillitis, and postoperative swelling or pain. However, the evidence isn't strong enough yet to confirm it works for any of these—the rating is insufficient reliable evidence for all of them.
What are the side effects?
Most commonly, diarrhea, heartburn, and stomach discomfort. Topically (on skin), it can cause dermatitis in sensitive people. Rarely, it can trigger anaphylaxis (a severe allergic reaction) in individuals with dandelion sensitivity, and some people report hay fever symptoms or asthma after exposure to dandelion pollen.
Is it safe if I'm allergic to ragweed?
No—dandelion belongs to the same plant family as ragweed, so if you're allergic to ragweed, chrysanthemums, marigolds, daisies, or related plants, you should avoid dandelion. Talk with your doctor or pharmacist first.
Can I take this while breastfeeding?
There isn't enough reliable information on safety while breastfeeding, so caution is advised. Talk with your doctor or pharmacist about whether it's right for you and your baby.
Why does this interact with so many medications?
Dandelion affects how your body processes drugs in several ways: it may boost insulin, thin blood slightly, retain potassium, and interact with liver enzymes that clear many medications from your system. These overlapping effects mean a broad list of drugs can be impacted.
