HelloPharmacist Scorecard of Parasite Support 450 mg by TerraVita Premium Collection

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 11, 2026

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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (4,150 mg) without saying how much of each component you get.

This product contains 2 active ingredients: mugwort and quassia, combined in a proprietary blend at 450 mg total. The capsule itself is made with gelatin and water as inactive ingredients.

Mugwort is a traditional herb used for various purposes, while quassia is a plant extract traditionally applied to skin conditions and used for other health goals. The specific amounts of each ingredient within the blend are not disclosed on the label.

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: parasite and digestive support.
  • We looked for evidence on: Intestinal parasite infection, Lice, Helminth infection, Tapeworm, Roundworm, Hookworm.
  • The closest evidence on file: Mugwort is rated "Insufficient Reliable Evidence To Rate" for Intestinal parasite infection (Natural Medicines).
  • Also on file: Quassia is rated "Insufficient Reliable Evidence To Rate" for Lice.

The evidence we hold for both ingredients in this product doesn't establish they work. For mugwort, we have insufficient reliable evidence to rate its use for anxiety, epilepsy, high blood pressure (hypertension), insomnia, or intestinal parasite infection.

Quassia also shows insufficient reliable evidence for seborrheic dermatitis, lice, rosacea, or other skin conditions listed. If you're considering this product for parasites or another specific condition, talk with your pharmacist or doctor — they can discuss what the current evidence actually supports.

The evidence, ingredient by ingredient Mugwort Quassia

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Mugwort can trigger allergic reactions, especially if you're sensitive to ragweed or related plants; symptoms may include asthma, rash, or in rare cases, anaphylaxis. High doses of mugwort may cause mania, and thujone levels in the herb can vary widely.

The safety data advises against mugwort during pregnancy and breastfeeding due to its traditional use to stimulate the uterus and insufficient safety information. Quassia in medicinal amounts can irritate your mouth and throat lining and cause nausea or vomiting; long-term use has been linked to vision changes and blindness in some reports.

The safety data advises against quassia during pregnancy and breastfeeding as well. In small food amounts quassia is generally well tolerated, but at the doses in a supplement, digestive upset is possible.

Side effects, ingredient by ingredient Mugwort Quassia

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 2 matched ingredients can interact with medications — Quassia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; heart-rhythm medications.
  • For scale: 198 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, double-check with your pharmacist if you take diabetes medications (risk of low blood sugar), diuretics (risk of low potassium), digoxin or other heart medications, or acid reflux drugs like H2-blockers, antacids, or PPIs — quassia may reduce how well the last group works. Altogether, these interactions span 197 individual medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product contains ingredients with insufficient evidence of effectiveness for parasite infection or other stated uses. Quassia interacts with several common medication types — especially diabetes, heart, and reflux drugs — so you'll need to check your exact medications before starting.

Pregnant or breastfeeding? Both ingredients should be avoided.

Talk to your pharmacist before adding this to your routine.

Quassia6 drug types · 198 drugs

Antidiabetes Drugs

In animals, quassia extract reduced levels of fasting glucose. Theoretically, quassia might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, concomitant use with cardiac medications might increase the risk of therapeutic and adverse effects.

Likelihood Possible Evidence D
Diuretic Drugs

Overuse of quassia might compound diuretic-induced potassium loss. There is some concern that people taking quassia along with potassium depleting diuretics might have an increased risk for hypokalemia. Initiation of potassium supplementation or an increase in potassium supplement dose may be necessary for some patients.
Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), and hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.

Likelihood Possible Evidence D
Antacids

Theoretically, due to reports that quassia increases stomach acid, quassia might decrease the effectiveness of antacids.

Likelihood Possible Evidence D
H2-Blockers

Theoretically, due to reports that quassia increases stomach acid, quassia might decrease the effectiveness of H2-blockers. The H2 blockers include cimetidine (Tagamet), ranitidine (Zantac), nizatidine (Axid), and famotidine (Pepcid).

Likelihood Possible Evidence D
Proton Pump Inhibitors (Ppis)

Theoretically, due to reports that quassia increases stomach acid, quassia might decrease the effectiveness of PPIs. PPIs include omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), pantoprazole (Protonix), and esomeprazole (Nexium).

Parasite Support 450 mg by TerraVita Premium Collection: Common Questions

Does Parasite Support 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Parasite Support 450 mg has a known interaction with 198 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Parasite Support 450 mg contains 2 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.
Is mugwort safe if I'm pregnant or breastfeeding?
No. Mugwort is traditionally used to stimulate the uterus and menstruation, so the safety data advises against it during pregnancy. There's also not enough safety information for breastfeeding. Talk to your doctor or pharmacist about what's right for you.
What's the most serious side effect I should watch for?
Mugwort can cause allergic reactions, especially if you're sensitive to ragweed — symptoms include rash, asthma, or in rare cases anaphylaxis. Quassia at medicinal doses can irritate your mouth and throat and cause nausea. Long-term quassia use has been linked to vision changes. If you notice any of these, stop and contact your healthcare provider.
Can quassia cause low blood sugar?
Possibly. In animals, quassia reduced fasting blood sugar levels. If you take diabetes medications, combined use might lower your blood sugar more than expected. You'll want to monitor your glucose closely and check with your pharmacist before starting.
Will this interfere with my reflux medication?
Possibly. Quassia may increase stomach acid, which could reduce how well H2-blockers (like famotidine), antacids, and PPIs (like omeprazole) work. It's a minor interaction, but mention it to your pharmacist so you both know what to watch for.
Does this product have fillers or other inactive ingredients?
Yes, the capsule is made with gelatin and water. Those are the only inactive ingredients listed on the label.
Is there any evidence this actually treats parasites?
Not in our data. For intestinal parasite infection, we have insufficient reliable evidence to rate mugwort. Your doctor or pharmacist can tell you what treatments actually have good evidence behind them.
