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: dyer's broom, supplied as a powder. There are no other 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

This is a single-ingredient Dyer's Broom product and its label doesn't state a use — see Dyer's Broom'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 data for dyer's broom in our records. The evidence supporting its use isn't established in the information available to us.

The evidence, ingredient by ingredient Dyer's Broom

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.

Dyer's broom contains potentially toxic alkaloids and has limited safety data, so caution is advised when using it. The herb may cause nausea, vomiting, or diarrhea — especially if overused.

Dyer's broom is rated possibly unsafe in pregnancy because it may affect the uterus and safety data is lacking, so avoid it if you're pregnant or planning to become pregnant. Avoid it while breastfeeding as well, since there isn't enough safety information in that setting.

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.

Dyer's broom is a single-ingredient product with very limited safety data and potential for gastrointestinal side effects. If you're pregnant, breastfeeding, or sensitive to caffeine, this isn't the right choice.

Before starting it, talk with your pharmacist or doctor about whether it's appropriate for you and check for caffeine interactions with your current routine.

Caffeine

Theoretically, dyer's broom might reduce the clearance of caffeine.
Dyer's broom contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females. This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in dyer's broom.
