Full disclosure
Ingredient Transparency · database check

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.

This product contains one active ingredient: waterhemp powder. There are no other active ingredients and no listed inactive fillers or binders in this formulation.

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 Hemp Agrimony product and its label doesn't state a use — see Hemp Agrimony'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.

No effectiveness ratings are on file for waterhemp in our data, so we can't tell you what it's intended to do or how well trial evidence supports it.

The evidence, ingredient by ingredient Hemp Agrimony

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.

The safety data advises against internal use of this product. Waterhemp (hemp agrimony) contains pyrrolizidine alkaloids — compounds that are toxic to the liver.

Chronic exposure to plants with these alkaloids can cause veno-occlusive disease, a serious liver condition. Acute symptoms can include severe abdominal pain, vomiting, diarrhea, and fluid buildup in the belly within days.

The safety data also advises against this product during pregnancy and while breastfeeding due to potential liver toxicity and lack of safety information.

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 — Hemp Agrimony.
  • The most serious interaction on file is rated Moderate.
  • For scale: 439 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're on any drugs that stress your liver (like acetaminophen, amiodarone, carbamazepine, isoniazid, or methotrexate) or any that speed up liver enzymes (like phenobarbital, phenytoin, rifampin, or rifabutin). Both interactions carry Moderate severity.

Waterhemp, Powder2 drug types · 438 drugs

Cytochrome P450 3A4 (Cyp3A4) Inducers

Hemp agrimony contains hepatotoxic pyrrolizidine alkaloids (PA) which are substrates of cytochrome P450 3A4 (CYP3A4). Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites. Some drugs that induce CYP3A4 include carbamazepine (Tegretol), phenobarbital, phenytoin (Dilantin), rifampin, rifabutin (Mycobutin), and others.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Hemp agrimony contains hepatotoxic pyrrolizidine alkaloids (PA). Theoretically, using hemp agrimony with hepatotoxic drugs might have additive adverse effects on the liver. Some drugs that can adversely affect the liver include acetaminophen (Tylenol and others), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), fluconazole (Diflucan), itraconazole (Sporanox), erythromycin (Erythrocin, Ilosone, others), phenytoin (Dilantin), lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), and many others.

Waterhemp Powder by TerraVita Premium Collection: Common Questions

Does Waterhemp Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Waterhemp Powder has a known interaction with 438 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Waterhemp Powder 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 while pregnant?
The safety data advises against it. Waterhemp contains compounds that are toxic to the liver, and there isn't enough safety information for pregnancy. Talk with your doctor or pharmacist before considering it.
Is it safe to take while breastfeeding?
No — the safety data advises against it while breastfeeding because of possible toxic compounds and no safety information. Your pharmacist or doctor can discuss alternatives with you.
What are pyrrolizidine alkaloids and why should I care?
They're plant compounds in this product that are toxic to your liver. Long-term exposure can cause a serious condition called veno-occlusive disease, and acute exposure can cause severe belly pain, vomiting, and diarrhea. That's why internal use of this product isn't generally recommended.
Does this product have any fillers or additives?
No — there are no inactive ingredients listed. It's waterhemp powder only.
What is waterhemp used for?
We don't have effectiveness data on file for waterhemp, so I can't tell you what it's intended to do or how well it works.
