HelloPharmacist Scorecard of Purge! by Eu Natural

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

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Purge Cleanse Complex” is a proprietary blend — the label gives one combined amount (1.30 Gram(s)) without saying how much of each component you get.

Purge! contains five active ingredients. BioPerine is a concentrated form of black pepper designed to enhance absorption of other nutrients.

Celery seed extract comes from celery plants and is included for its traditional cleansing properties. Montmorency whole tart cherry is a fruit ingredient known for its antioxidant content.

Chanca piedra extract is derived from a plant traditionally used for kidney and gallstone support. Hydrangea root extract rounds out the blend.

The product also contains cellulose and rice extract as inactive ingredients.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: promote healthy uric acid levels.
  • We looked for evidence on: Gout, Kidney stones (nephrolithiasis), Uric acid management, Urinary tract health.
  • The strongest evidence on file: Chanca Piedra is rated "Possibly Effective" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Sour Cherry is rated "Insufficient Reliable Evidence To Rate" for Gout.
  • Also on file: Celery is rated "Insufficient Reliable Evidence To Rate" for Gout.

The effectiveness data for Purge! are limited. BioPerine (black pepper) has insufficient reliable evidence for hay fever, asthma, athletic performance, headache, depression, and diarrhea.

Celery seed extract likewise shows insufficient evidence for sexual dysfunction, anxiety, headache, depression, diabetes, and indigestion. Sour cherry is rated possibly effective for athletic performance, but has insufficient evidence for ADHD, brain function, exercise-related muscle soreness, respiratory infections, and fibromyalgia.

Chanca piedra is possibly effective for kidney stones, but likely ineffective for hepatitis B. No effectiveness ratings exist in our data for hydrangea root extract.

The evidence, ingredient by ingredient Black Pepper Celery Sour Cherry Chanca Piedra Hydrangea

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

BioPerine is generally well tolerated in food amounts, though concentrated supplements warrant caution. The most common side effects are a burning aftertaste, indigestion, and reduced taste perception; allergic reactions are rare.

Celery seed carries a caution label — while food amounts are likely fine, the safety of supplement-strength doses isn't well studied, and medicinal amounts should be avoided in pregnancy because they may affect the uterus. There's insufficient data on celery while breastfeeding.

Sour cherry is rated likely safe in pregnancy and lactation but is generally well tolerated as food or concentrate; abdominal pain and loose stools have been reported, particularly at higher doses. Chanca piedra is often well tolerated short-term, but safety data are limited; the facts advise against use in pregnancy and while breastfeeding due to insufficient information.

Hydrangea root extract has limited human safety data and should be avoided in pregnancy and breastfeeding; it may cause gastroenteritis, dizziness, or chest tightness.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

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

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.

Likelihood Possible Evidence D

Celery Seed Extract8 drug types · 651 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, celery root might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
Celery root contains the constituents falcarinol and falcarindiol. Laboratory research suggests that these constituents can inhibit platelet aggregation. This effect has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, celery seed extract might have additive effects with antihypertensive drugs.
Clinical research suggests that taking celery seed extract may reduce daytime systolic blood pressure by about 12 mmHg compared to less than 1 mmHg with placebo.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, celery might increase levels of drugs metabolized by CYP1A2.
In vitro and animal research suggests that constituents of celery can inhibit CYP1A2. This effect has not been reported in humans.

Likelihood Possible Evidence D
Levothyroxine (Synthroid, Others)

Theoretically, celery seed might decrease the effects of levothyroxine.
Several cases of hypothyroidism with low T4 levels have been reported in people who were previously stabilized on levothyroxine and then started taking celery seed tablets. They presented with symptoms such as lethargy, bloating, and dry skin, and recovered when celery seed was stopped. However, celery stem and leaf has been associated with case reports of hyperthyroidism in patients with no pre-existing thyroid disorders.

Likelihood Possible Evidence D
Lithium

Theoretically, celery might reduce excretion and increase levels of lithium due to potential diuretic effects.
Celery is thought to have diuretic properties. However, this effect has not been confirmed in humans.

Likelihood Probable Evidence D
Venlafaxine (Effexor)

Theoretically, celery root extract might increase blood levels of venlafaxine.
There is one case report of a patient who experienced medication-induced bipolar disorder after beginning to take celery root extract 1000 mg daily along with venlafaxine 75 mg and St. John's wort 600 mg daily. Symptoms included confusion, speech abnormalities, manic affect, and visual hallucinations. The plasma level of venlafaxine was 476.8 ng/mL (normal range 195-400 ng/mL). It is theorized that celery root increased venlafaxine levels by inhibiting cytochrome P450 2D6.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Theoretically, celery juice might increase the effects and side effects of acetaminophen.
Animal research suggests that concomitant use of celery juice plus acetaminophen prolongs the effects of acetaminophen. This effect has been attributed to a decrease in hepatic cytochrome P450 activity. However, other animal research shows that pretreatment with celery root extract protects against acetaminophen-induced acute liver failure. These effects have not been reported in humans.

Likelihood Possible Evidence D
Photosensitizing Drugs

Theoretically, celery might increase the risk of photosensitivity reactions when taken with photosensitizing drugs.
Laboratory research shows that celery contains photosensitizing agents such as phenols and psoralens.

Likelihood Possible Evidence D

Hydrangea Root Extract1 drug type · 1 drug

Lithium

Hydrangea is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, hydrangea might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Purge! by Eu Natural: Common Questions

Does Purge! by Eu Natural interact with any medications?
Yes. Based on its ingredients, Purge! has a known interaction with 1,256 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Purge! contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this work for kidney stones?
Chanca piedra, one of the ingredients, is rated possibly effective for kidney stones based on the evidence we hold. The other ingredients don't have established effectiveness for that purpose in our data.
Can I take Purge! if I'm pregnant?
No — celery seed should be avoided in medicinal amounts during pregnancy because it may affect the uterus, and there isn't enough safety information for chanca piedra or hydrangea root in pregnancy. Talk to your doctor or pharmacist about whether this product is right for you.
What are the most common side effects?
From BioPerine, a burning aftertaste, indigestion, and reduced taste perception are most common. Sour cherry at higher doses can cause abdominal pain and loose stools. Chanca piedra may cause abdominal pain, nausea, or vomiting. Allergic reactions to celery (including anaphylaxis in sensitive people) are rare but serious.
Is this safe while breastfeeding?
There isn't enough reliable safety data for celery seed, chanca piedra, or hydrangea root while breastfeeding, so they're best avoided. Sour cherry is rated likely safe while breastfeeding. Talk to your pharmacist or doctor before using this product if you're nursing.
What is BioPerine and why is it in here?
BioPerine is a concentrated form of black pepper (specifically its active compound piperine). It's included to help your body absorb the other ingredients more effectively — a practice called bioenhancement.
Do I need to worry about a celery allergy?
If you have a celery allergy, you should avoid this product — celery seed can trigger reactions ranging from itching and burning in the mouth to severe swelling of the throat and anaphylactic shock in sensitive people.
