HelloPharmacist Scorecard of Flow Secure + by Herbal Goodness

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

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 3 active ingredients.
  • “Extract Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Flow Secure + is a liquid supplement with 3 active ingredients. Shepherd's Purse extract and Yarrow extract have been used traditionally for women's health, while Dong Quai extract is an herbal ingredient with a long history in traditional medicine.

The product contains no inactive fillers or other ingredients listed.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: protection and comfort during menstrual cycle.
  • We looked for evidence on: Dysmenorrhea, Menorrhagia, Premenstrual syndrome (PMS), Menopausal symptoms, Postpartum complications, Menstrual bleeding — and 2 related terms.
  • 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.
  • Also on file: Yarrow is rated "Insufficient Reliable Evidence To Rate" for Dysmenorrhea.

The evidence on whether these ingredients work for their intended purposes isn't established in our data. Shepherd's Purse has been studied for postpartum complications and menorrhagia (heavy menstrual bleeding), but we hold insufficient reliable evidence to rate it either way.

Yarrow and Dong Quai have similar gaps — the evidence available isn't strong enough to say whether they're effective for the conditions they're traditionally used for. If you're considering this product for a specific health goal, talk with your pharmacist or doctor about what the science actually supports.

The evidence, ingredient by ingredient Shepherd's Purse Yarrow Dong Quai

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Shepherd's Purse and Yarrow both carry cautions: human safety data are limited when used short-term, and allergic reactions to yarrow can happen. Both are likely unsafe in pregnancy because they may affect the uterus, and neither has enough safety data to use while breastfeeding — so avoid them during both periods.

Dong Quai is also likely unsafe in pregnancy and best avoided while breastfeeding; additionally, it may increase bleeding risk and cause skin sensitivity to sunlight, so use with care if you take it. When used as directed in small amounts for short periods, Shepherd's Purse and Yarrow appear generally well tolerated, and Dong Quai is generally well tolerated orally — though burping and flatulence are the most common side effects reported with Dong Quai.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Shepherd's Purse, Yarrow, Dong Quai.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 407 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.

Double-check this product with your pharmacist if you take warfarin (Coumadin) or other blood thinners — Dong Quai carries a Major interaction. Also flag any use of antiplatelet drugs, lithium, thyroid hormone replacement, or estrogens, which have Moderate interactions documented.

And mention any sedative medications, since Shepherd's Purse may add to their drowsy effects.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Flow Secure + may be worth considering if you're looking for traditional herbal support, but it's not for you if you're pregnant, breastfeeding, or taking warfarin, other blood thinners, lithium, thyroid medication, or estrogen therapy. Even if you don't take those drugs, check your full medication list with a pharmacist before starting.

Shepherd's Purse Extract2 drug types · 264 drugs

Cns Depressants

Theoretically, concomitant use with drugs with sedative properties may cause additive effects and side effects.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, concomitant use may interfere with thyroid dysfunction therapy.

Likelihood Possible Evidence D

Dong Quai extract3 drug types · 163 drugs

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Likelihood Possible Evidence D

Yarrow Extract1 drug type · 1 drug

Lithium

Theoretically, taking yarrow with lithium might increase the levels and adverse effects of lithium.
Animal research shows that yarrow has diuretic activity. Theoretically, due to these potential diuretic effects, yarrow might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Flow Secure + by Herbal Goodness: Common Questions

Does Flow Secure + by Herbal Goodness interact with any medications?
Yes. Based on its ingredients, Flow Secure + has a known interaction with 407 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Flow Secure + contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 Flow Secure + if I'm pregnant or breastfeeding?
No. Both Shepherd's Purse and Yarrow are likely unsafe in pregnancy because they may stimulate the uterus, and there isn't enough safety data to use either while breastfeeding. Dong Quai is also best avoided during both pregnancy and breastfeeding. Talk with your doctor or pharmacist about what's safe for you.
What are the most common side effects?
Shepherd's Purse and Yarrow are generally well tolerated when used short-term in small amounts. Dong Quai is also generally well tolerated orally, with burping and flatulence being the most common side effects. Yarrow applied to skin can cause allergic reactions like dermatitis or rash.
Does this product actually work for its intended use?
We don't have strong enough evidence in our data to say whether Shepherd's Purse, Yarrow, or Dong Quai work for the conditions they're traditionally used for. If you're considering it for a specific reason, ask your pharmacist what the research actually shows.
Is it safe to use with other medications?
That depends on which medications you take. The biggest concern is if you're on warfarin or other blood thinners — Dong Quai increases your bleeding risk. You should also check with a pharmacist if you take lithium, thyroid medication, estrogens, or sedative drugs before adding this product.
Can Flow Secure + cause sun sensitivity?
Yes, Dong Quai may increase your skin's sensitivity to sunlight. If you use this product, be extra careful with sun exposure — use sunscreen and protective clothing.
