HelloPharmacist Scorecard of Capsella Bur. Shepherd's Purse by Wise Woman Herbals

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 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

This product contains one active ingredient: Shepherd's Purse, delivered in liquid form with spring water and alcohol as the carrier. Shepherd's Purse is a traditional herb—the whole plant preparation (also called Capsella bursa-pastoris) has been used historically for certain women's health concerns.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: heavy menstrual bleeding and postpartum bleeding.
  • We looked for evidence on: Menorrhagia, Postpartum complications, bleeding control, hemostasis.
  • The closest evidence on file: Shepherd's Purse is rated "Insufficient Reliable Evidence To Rate" for Postpartum complications (Natural Medicines).
  • Also on file: Shepherd's Purse is rated "Insufficient Reliable Evidence To Rate" for Menorrhagia.

The evidence for Shepherd's Purse isn't established for the uses listed here. For both postpartum complications and heavy menstrual bleeding (menorrhagia), the data we hold shows insufficient reliable evidence to rate how well it works.

That means we don't have enough solid human studies to say whether it's effective for these purposes.

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.

Human safety data are limited for this herb, so we only know it seems well tolerated in small amounts over the short term. Adverse effects traditionally linked to it include sedation, changes in blood pressure, abnormal thyroid function, irregular menstruation, and heart palpitations, though these aren't confirmed in modern trials.

During pregnancy, the safety data advises against it—it may stimulate the uterus. There isn't enough safety information to use it while breastfeeding either, so talk with your doctor or pharmacist about whether it's right for you in those situations.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Shepherd's Purse is a traditionally used herb, but solid evidence for its effectiveness isn't established, and human safety data are limited. If you take any sedative or thyroid medication, you'll want to check with us or your pharmacist first.

A short conversation before you start can make sure it won't get in the way of your other drugs.
