HelloPharmacist Scorecard of Chaparral Leaf Strawberry Flavor by TerraVita

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

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: Chaparral Leaf Glycerite Liquid Extract. It's a liquid extract of chaparral leaf in glycerin, flavored with strawberry.

The glycerin and strawberry flavor are inactive ingredients (excipients) that serve as the base and flavoring.

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

We hold no effectiveness ratings for chaparral in our data, so we can't tell you what this ingredient is meant to do or how well it works.

The evidence, ingredient by ingredient Chaparral

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.

Chaparral has been linked to serious liver and kidney toxicity and is not recommended. Orally, it can cause jaundice, fatigue, abdominal pain, dark urine, light stools, nausea, diarrhea, weight loss, fever, and loss of appetite.

More severe cases have resulted in cirrhosis, acute liver failure, and have required liver transplant. The active compound nordihydroguaiaretic acid (NDGA) in chaparral is thought to be responsible for this toxicity.

Chaparral is rated likely unsafe in pregnancy and while breastfeeding because of toxicity concerns and lack of safety data. Do not use it if you're pregnant or nursing.

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 — Chaparral.
  • The most serious interaction on file is rated Moderate.
  • For scale: 371 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, check whether you're on any hepatotoxic drugs (drugs toxic to the liver), including certain chemotherapy agents, antibiotics, high-dose acetaminophen, or others. This product may add to their liver-damaging effects.

If you take any of these, talk with your doctor or pharmacist before starting.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

The safety data here is a serious red flag: chaparral carries documented risk of severe liver and kidney damage, and that risk is why it's not recommended. If you're considering this product, talk with your doctor or pharmacist first — especially if you have any liver or kidney concerns or take other medications that stress the liver.

This is not a decision to make on your own.
