HelloPharmacist Scorecard of Shepherd's Purse by Herbal Terra

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 is a liquid extract made from the dried seedpods of certified organic Shepherd's Purse, a plant traditionally used in herbal medicine. The only other ingredient listed is menstruum, which is the liquid carrier used to make the extract.

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 Shepherd's Purse product and its label doesn't state a use — see Shepherd's Purse'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 Shepherd's Purse isn't well established in our data. For both postpartum complications and menorrhagia (heavy menstrual bleeding), the research we hold shows insufficient reliable evidence to rate how well it works.

That doesn't mean it doesn't work — it means larger, better studies would be needed to say for sure.

The evidence, ingredient by ingredient Shepherd's Purse

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.

Shepherd's Purse appears to be fairly well tolerated when used in small amounts for short periods. That said, human safety data are limited, so we don't have a lot of information on long-term use.

Adverse effects historically associated with it include sedation, changes in blood pressure, abnormal thyroid function, irregular periods, and heart palpitations — though these weren't necessarily proven in controlled studies. Do not use this product during pregnancy; it may stimulate the uterus and is rated likely unsafe.

There isn't enough safety information to use it while breastfeeding, so skip it if you're nursing. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.

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 — Shepherd's Purse.
  • The most serious interaction on file is rated Moderate.
  • For scale: 264 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.

Check your exact medications if you take CNS depressants (sedatives, sleep aids, certain antidepressants) or thyroid hormone replacements before using this product. Both carry moderate interaction risks with Shepherd's Purse.

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.

Shepherd's Purse is traditionally used for menstrual and postpartum concerns, but we don't have strong evidence yet that it works. If you take sedative drugs or thyroid medication, you'll want to check your exact prescriptions with our tool first.

Short-term use in small amounts seems generally well tolerated, but human safety data are limited — talk with your pharmacist before you start.
