HelloPharmacist Scorecard of Chickweed 400 mg by NOW

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 16, 2026

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: chickweed, a traditional botanical used for various health purposes. The capsule also contains gelatin and stearic acid as inactive ingredients — fillers and capsule material.

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 Chickweed product and its label doesn't state a use — see Chickweed'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 we hold doesn't establish that chickweed works for diabetes, high cholesterol (hyperlipidemia), or weight management — the data rates all of these uses as insufficient reliable evidence to rate. If you're considering it for one of these reasons, talk it over with your doctor or pharmacist about what the science actually supports.

The evidence, ingredient by ingredient Chickweed

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.

Chickweed is generally well tolerated for short-term use, but high-quality safety data are limited. When applied topically, chickweed extract has been reported to cause contact dermatitis (skin irritation) in some people.

There isn't enough safety information to recommend it during pregnancy or breastfeeding — the safer choice is to avoid it in both.

Side effects, ingredient by ingredient Chickweed

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 the ingredients we could check. Run your exact medications through the search tool on this page to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Chickweed is a single-ingredient supplement with no documented drug interactions, so medication conflicts aren't the concern here. The bigger question is whether it actually works — and the evidence we hold doesn't support its use for diabetes, cholesterol, or weight management.

If you're pregnant or breastfeeding, skip it. Talk with your doctor or pharmacist about whether it makes sense for what you're trying to do.

Chickweed 400 mg by NOW: Common Questions

Does Chickweed 400 mg by NOW interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Chickweed 400 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Chickweed 400 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 Chickweed while pregnant or breastfeeding?
No — there isn't enough safety information during pregnancy and breastfeeding, so avoidance is the safer choice. Talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or nursing.
Does chickweed actually help with weight loss or cholesterol?
The evidence we hold doesn't support either use — the data rates both as insufficient reliable evidence. If that's why you're interested, your doctor or pharmacist can point you toward options with stronger backing.
Is there any risk of side effects?
Chickweed is generally well tolerated for short-term use, though high-quality safety data are limited. When applied to skin, chickweed extract has been reported to cause contact dermatitis in some people. If you're using it topically, watch for any irritation.
Will this interact with my medications?
No interactions are documented in our data for the ingredients we checked. That said, you should run your exact medications through the search tool on this page to confirm — and if you're taking anything prescription, mention this supplement to your doctor or pharmacist.
What is chickweed used for?
Chickweed is a traditional botanical that people use for various purposes, including diabetes, high cholesterol, and weight management — though the evidence we hold doesn't establish that it works for any of these.
