Full disclosure
Ingredient Transparency · database check

Every active ingredient lists its own amount on the label.

Why this rating?

There are no inactive ingredients listed.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: maintain healthy mucous membrane and stomach function.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't hold effectiveness data for cudweed in our records, so we can't tell you whether it works for any particular purpose. The research backing isn't established in the information available to us.

How safe is it?

Limited data
Safety Information · database check
Limited information

Little studied safety information is available for these ingredients — that is not the same as being safe.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 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.

Cudweed has limited modern safety data, so caution is warranted — talk with a healthcare provider before you start it. The safety information advises against use during pregnancy and while breastfeeding due to insufficient reliable data in those settings.

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 — Cudweed.
  • The most serious interaction on file is rated Moderate.

  • For scale: 86 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.

If you take any antidiabetes drugs — including insulin, glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), pioglitazone (Actos), rosiglitazone (Avandia), or similar medications — check with your doctor or pharmacist before adding this product. There's a Moderate risk that cudweed could lower your blood glucose too much.

The bottom line

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

Cudweed may interact with blood-glucose-lowering medications, so it's not a "grab and go" choice if you take diabetes drugs. If you're considering it, check with your doctor or pharmacist first, especially if you're on insulin or other antidiabetes medications.

Because safety data are limited overall, get personalized advice from your own healthcare provider before starting.

Preliminary research in rats shows that cudweed might lower blood glucose levels. Theoretically, taking cudweed with drugs that lower blood glucose levels might increase the risk of hypoglycemia. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
