HelloPharmacist Scorecard of Hawkweed 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.

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: hawkweed (mouse-ear hawkweed), at 450 mg per capsule. The capsule itself is made from gelatin and water, which are inactive ingredients that help deliver the hawkweed.

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 Mouse-ear Hawkweed product and its label doesn't state a use — see Mouse-ear Hawkweed'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.

The evidence for hawkweed is thin. For both flatulence and wound healing, there isn't enough reliable data to rate whether it works.

The ingredient has a history of traditional use, but modern human studies backing those uses are lacking.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Hawkweed has been used traditionally, but it hasn't been studied thoroughly in modern clinical settings, so there's real uncertainty about how safe it is. The safety data doesn't support use during pregnancy or while breastfeeding — if you're in either situation, talk with your doctor or pharmacist before taking it.

No adverse effects from the ingredient itself are documented in the data we hold, though that doesn't mean they won't occur.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for this ingredient. Still, because hawkweed's effects on your body aren't well established in modern research, check with your pharmacist before combining it with any medications you take regularly.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

Hawkweed is a traditional remedy with minimal modern evidence behind it. If you're curious and not pregnant, breastfeeding, or on multiple medications, a conversation with your pharmacist can help you decide if it's worth trying.

Given the gaps in safety and effectiveness data, it's not a first choice for any condition.

Hawkweed 450 mg by TerraVita Premium Collection: Common Questions

Does Hawkweed 450 mg by TerraVita Premium Collection interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Hawkweed 450 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Hawkweed 450 mg 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. There isn't enough information to know whether hawkweed is safe during pregnancy, so it's best to talk with your doctor or pharmacist before using it if you're pregnant or planning to become pregnant.
Is it safe to breastfeed while taking Hawkweed 450 mg?
No reliable safety data exists for breastfeeding, so it's best to avoid it during lactation. Talk with your doctor or pharmacist about whether this is right for you.
Does hawkweed actually work for flatulence or wound healing?
The evidence isn't established in the data we hold. Both uses have insufficient reliable evidence to rate, so we can't say whether it works for either condition.
What is hawkweed traditionally used for?
It has a history of traditional use — the product lists flatulence and wound healing — but modern human studies supporting those uses are limited.
Are there any side effects I should know about?
No adverse effects from hawkweed itself are documented in our data. That said, because the ingredient hasn't been thoroughly studied in modern research, unknown effects could occur — report anything unusual to your pharmacist.
