HelloPharmacist Scorecard of HME-H by Pure Herbs

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 8 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,935 mg) without saying how much of each component you get.

Pure Herbs HME-H contains 8 ingredients total. The active components include horsetail aerial parts extract (used traditionally for urinary and structural support, though evidence is insufficient to rate its effectiveness for the claimed uses), oat straw aerial parts extract (oats have likely effective evidence for cholesterol and heart health), cassava root extract, and a proprietary blend that includes kelp whole algae extract, bladderwrack algae extract, Irish moss extract, wheat germ seed extract, and hemidesmus indicus root extract.

The product contains no inactive other ingredients listed.

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: Supports healthy kidney function.
  • We looked for evidence on: Urinary tract infections (UTIs), Urinary incontinence, Kidney stones (nephrolithiasis), Renal health, Urinary health.
  • The closest evidence on file: Horsetail is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Horsetail is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs), Urinary incontinence.
  • Also on file: Wheatgrass is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Urinary tract infections (UTIs).

The evidence for this product's effectiveness is mixed and limited. Oat straw is likely effective for managing cholesterol levels (dyslipidemia) and supporting heart health.

Horsetail has insufficient reliable evidence to rate it for urinary incontinence, weight management, or the other conditions on file. Cassava root also carries insufficient evidence for diabetes or dehydration-related claims.

For the five remaining ingredients — kelp, bladderwrack, Irish moss, wheat germ, and hemidesmus indicus — effectiveness ratings are not on file.

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horsetail is generally well tolerated short-term in healthy adults, but long-term use carries real risks. The most common side effects are abdominal bloating, increased bowel movements, and nausea.

Importantly, horsetail contains thiaminase, which can deplete thiamine (vitamin B1) with prolonged use — though Canadian products are required to be certified thiaminase-free. Safety data is insufficient for horsetail in pregnancy and breastfeeding; avoid use during both.

Oats are generally considered safe when eaten as food; concentrated supplements during pregnancy and breastfeeding are less studied. Oat side effects include bloating, gas, and abdominal distension, which usually fade with continued use.

Cassava safety depends heavily on processing: properly cooked cassava as food is common, but raw or poorly processed cassava can cause cyanide poisoning. Concentrated cassava supplements are not well studied and are best avoided.

Additionally, cassava carries possible safety concerns in pregnancy and breastfeeding.

Meds to double-check

Moderate interaction found
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?
  • 6 of the 6 matched ingredients can interact with medications — Fucus Vesiculosus, Oats, Horsetail, Wheatgrass, Cassava, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,083 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.

Before taking Pure Herbs HME-H, check your medications against these drug types: antidiabetes drugs and insulin (risk of low blood sugar), diuretics (risk of potassium loss), lithium, HIV reverse transcriptase inhibitors and efavirenz, and thyroid hormone replacement. Horsetail and oat straw carry Moderate risks with these categories.

Kelp Whole Algae Extract9 drug types · 891 drugs

Amiodarone (Cordarone)

Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Lithium

Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using thyroid hormone could alter the effects of thyroid hormone.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.

Likelihood Unlikely Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.

Likelihood Possible Evidence D

Wheat Germ Seed Extract2 drug types · 272 drugs

Antidiabetes Drugs

Theoretically, taking wheatgrass with antidiabetes drugs might lower blood glucose levels and increase the risk of hypoglycemia.
Animal research shows that taking wheatgrass stimulates the release of insulin from beta-cells and lowers blood glucose.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, wheatgrass might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that wheatgrass induces CYP1A2 enzymes.

Likelihood Possible Evidence D

Horsetail Aerial Parts Extract5 drug types · 188 drugs

Antidiabetes Drugs

Theoretically, taking horsetail with antidiabetes drugs might increase the risk of hypoglycemia.
Equisetum myriochaetum has demonstrated hypoglycemic activity in clinical research. In an animal diabetic model, Equisetum giganteum had hypoglycemic effects. It is unclear whether other horsetail species have hypoglycemic effects.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, taking horsetail with diuretic drugs might increase potassium loss and the risk of hypokalemia.
Laboratory research shows that various species of horsetail have diuretic properties. Due to its diuretic effects, there has been concern that taking horsetail along with potassium-depleting diuretics might increase the risk for hypokalemia. However, pharmacokinetic research in humans shows that taking horsetail 900 mg daily for 4 days does not affect urinary excretion of electrolytes, including potassium and sodium, despite having a diuretic effect similar to taking hydrochlorothiazide 25 mg daily. It is unclear if taking horsetail for a longer duration would affect electrolyte levels. Until more is known, use with caution.

Likelihood Possible Evidence D
Efavirenz (Sustiva)

Theoretically, horsetail might decrease the levels and clinical effects of efavirenz.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral regimen that included efavirenz. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing horsetail, the viral loads became undetectable in both cases. The exact mechanism of this interaction is unknown. It is also unclear if this interaction is specific to efavirenz or if it is related to various components of antiretroviral therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, horsetail might increase the levels and adverse effects of lithium.
Animal research suggests that horsetail has diuretic properties. Theoretically, due to these potential diuretic effects, horsetail might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Nucleoside Reverse Transcriptase Inhibitors (Nrtis)

Theoretically, horsetail might decrease the levels and clinical effects of NRTIs.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral therapy. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing the supplement, the viral loads became undetectable in both cases. The exact mechanism of these interactions is unknown. It is also unclear if these interactions are specific to NRTIs or if they are related to various components of antiretroviral therapy.

Likelihood Possible Evidence D

Oat Straw Aerial Parts Extract2 drug types · 86 drugs

Antidiabetes Drugs

Theoretically, oats may have additive effects with antidiabetic agents and might increase the risk of hypoglycemia.
Consuming oats can decrease blood glucose in patients with diabetes. In those who require insulin, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control.

Likelihood Possible Evidence D
Insulin

Concomitant use of oats and insulin might increase the risk of hypoglycemia.
In patients with insulin-dependent type 2 diabetes, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control.

Likelihood Possible Evidence B

Irish Moss Extract3 drug types · 22 drugs

Amiodarone (Cordarone)

Theoretically, combining sea moss with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with sea moss, which contains approximately 4-7 mcg of iodine per gram, might increase the risk of adverse effects from iodine, including altered thyroid function.

Likelihood Possible Evidence D
Antithyroid Drugs

Due to its iodine content, sea moss might alter the effects of antithyroid drugs.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of antithyroid drugs.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, sea moss might alter the effects of thyroid hormone.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of thyroid hormone.

Likelihood Possible Evidence D

Cassava Root Extract1 drug type · 16 drugs

Thyroid Hormone

Evidence from human and animal research suggests that cassava root has marked antithyroid effects, particularly if poorly processed or if consumed as part of a protein-deficient diet. Also, clinical research shows that consuming boiled cassava leaves 200 grams twice daily for 9 days significantly reduces levels of the thyroid hormones triiodothyronine and thyroxine. Theoretically, cassava may alter thyroid function, reduce thyroid hormone levels, and interfere with thyroid hormone-replacement therapy.

HME-H by Pure Herbs: Common Questions

Does HME-H by Pure Herbs interact with any medications?
Yes. Based on its ingredients, HME-H has a known interaction with 1,082 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
HME-H contains 8 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.
Is it safe to take this during pregnancy?
The facts show insufficient safety data for horsetail in pregnancy — avoid it. Cassava is rated possibly unsafe in pregnancy. Oats eaten as food are generally considered safe, but concentrated oat supplements are less studied. Talk with your doctor or pharmacist before using this product if you're pregnant.
What are the most common side effects?
Horsetail may cause abdominal bloating, increased bowel movements, and nausea. Oat straw can cause gas, bloating, and abdominal distension, especially when you first start it — these typically improve with continued use. Cassava carries a risk of nausea, stomach pain, and dizziness if not properly processed.
Will this help me lose weight?
Horsetail's effectiveness for weight management is insufficient to rate based on the evidence we hold. Oat straw's documented benefit is for cholesterol and heart health, not weight loss.
I'm on levothyroxine for my thyroid. Can I take this?
This product contains cassava root, which has antithyroid effects that could interfere with how your thyroid medication works — especially if the cassava is not well processed. Definitely check with your pharmacist before starting.
What is oat straw actually for?
Oat straw is the aerial parts of the oat plant. It's likely effective for managing cholesterol and supporting heart health based on clinical evidence. It's not the same as eating oatmeal.
