HelloPharmacist Scorecard of Headache Complex Mint 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 6, 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 (0.13 mL) without saying how much of each component you get.

This liquid product contains 2 active ingredients: White Willow Glycerite Liquid Extract and Feverfew Glycerite Liquid Extract. Both are delivered as glycerites—plant extracts suspended in glycerin, which serves as both a preservative and sweetener.

The inactive ingredients are glycerin and mint flavor. There are no other fillers or binders in this formulation.

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: headache relief.
  • We looked for evidence on: Tension headache, Migraine, Fever.
  • The closest evidence on file: Feverfew is rated "Insufficient Reliable Evidence To Rate" for Tension headache (Natural Medicines).

The evidence for feverfew in this product is not established. Our data shows insufficient reliable evidence to rate feverfew for tension headaches or other conditions it's traditionally used for.

That doesn't mean it doesn't work—it means well-designed clinical trials haven't yet proven it does. If you're considering this for headaches, talk with your doctor or pharmacist about what the research currently supports.

The evidence, ingredient by ingredient Feverfew

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.

Feverfew is generally well tolerated when taken short-term, though some people experience mouth irritation or allergic reactions. The most common side effects are gastrointestinal: heartburn, nausea, diarrhea, constipation, bloating, abdominal pain, and flatulence.

Skin rash can occur in sensitive individuals. One important note: if you stop taking feverfew after long-term use, some people report "post-feverfew syndrome"—anxiety, headaches, and insomnia—so stopping should be gradual.

During pregnancy, feverfew may stimulate the uterus and is rated possibly unsafe; the safety data advises against it. There isn't enough information to know whether it's safe while breastfeeding, so it's best avoided.

Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding before starting this product.

Side effects, ingredient by ingredient Feverfew

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 1 matched ingredient can interact with medications — Feverfew.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 930 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 doctor or pharmacist if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding). Also ask about any medications processed by your liver through CYP2C19, CYP2D6, CYP1A2, CYP2C9, CYP3A4, or CYP2C8 pathways (Moderate risk of raised drug levels).

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 is designed for headache relief, but the evidence for how well it works isn't established in our data. The main concern is that feverfew interacts with blood thinners and many drugs your liver processes, potentially raising drug levels.

If you take any prescription medications—especially anticoagulants or antiplatelet drugs—check with your doctor or pharmacist before starting. Avoid during pregnancy; don't use while breastfeeding without medical guidance.
