HelloPharmacist Scorecard of Winter Immune-Booster by Mountain Meadow 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

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 6 active ingredients.
  • “Proprietary Blend of extracts” is a proprietary blend — the label gives one combined amount (1.25 mL) without saying how much of each component you get.

This liquid contains 6 ingredients, five of which are active herbal extracts: horsetail herb, stinging nettle leaf, skullcap herb, oatstraw herb, and chamomile flower. The product also lists a proprietary blend, which means some of those ingredients may be combined in that blend rather than listed separately — the label should tell you more.

The remaining ingredients are vegetable glycerine and distilled water, which keep the liquid stable and drinkable.

Does it work?

Strong 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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Oats) (Natural Medicines).
  • On file: Dyslipidemia — rated "Likely Effective" (Oats) (Natural Medicines).
  • On file: Diabetes — rated "Possibly Effective" (Stinging Nettle) (Natural Medicines).
  • On file: Gastric cancer — rated "Possibly Effective" (Oats) (Natural Medicines).

The evidence for what this product actually does is thin. Oatstraw shows up as likely effective for cholesterol (dyslipidemia) and heart health — those are the strongest claims here.

Stinging nettle rates as possibly effective for diabetes, though that's not the same as proven. For everything else — horsetail for hair loss or incontinence, skullcap for stress or sleep, chamomile's roles — the data we hold says there's insufficient reliable evidence.

That doesn't mean they don't work, just that the science isn't there yet to back the claims up.

The evidence, ingredient by ingredient Horsetail Stinging Nettle German Chamomile Skullcap Oats

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horsetail isn't recommended long-term; short-term use by healthy adults is okay, but crude horsetail can contain thiaminase, which breaks down thiamine (vitamin B1) — this is a real concern with extended use, though Canadian products are required to be tested free of this. Most common side effects from horsetail are abdominal bloating, more bowel movements, and nausea.

Stinging nettle is generally well tolerated; constipation or diarrhea can happen, and fresh plant contact causes itching and rash. Skullcap has limited safety data; it can cause drowsiness, cognitive fuzziness, and stomach upset — doses of 200 mg or higher are more likely to trigger sedation.

Oatstraw is well tolerated as a food; you might notice bloating, gas, or flatulence from the fiber. For pregnancy and breastfeeding: horsetail and skullcap should be avoided — not enough safety data.

Stinging nettle also should be avoided in pregnancy and while breastfeeding due to traditional concerns and lack of data. Oatstraw as a food is considered safe in pregnancy and while breastfeeding, though supplement forms are less studied.

We hold no safety data for chamomile or cornsilk in pregnancy or 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?
  • 5 of the 5 matched ingredients can interact with medications — Stinging Nettle, Oats, Horsetail, German Chamomile, Skullcap.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,105 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 before starting if you take antidiabetes drugs (including insulin) or blood pressure pills that affect potassium, blood thinners like warfarin, lithium, HIV medications, or sedatives and CNS depressants — all interactions are Moderate severity. No interactions are documented for chamomile or cornsilk, which we could not fully check.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product is worth a conversation with your pharmacist if you take any diabetes medication, blood thinners, lithium, water pills, or sedatives. If you're pregnant or breastfeeding, skip it — the safety data just isn't there.

For a generally healthy adult not on those medications, it's probably okay short-term, but the evidence it actually does what you're hoping for is limited.

Skullcap herb extract full monograph & interactions

Horsetail herb 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.

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

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.

Winter Immune-Booster by Mountain Meadow Herbs: Common Questions

Does Winter Immune-Booster by Mountain Meadow Herbs interact with any medications?
Yes. Based on its ingredients, Winter Immune-Booster has a known interaction with 1,104 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Winter Immune-Booster contains 6 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 this if I'm on metformin or another diabetes medication?
No — don't start this without talking to your doctor or pharmacist first. Horsetail, stinging nettle, and oatstraw can all lower blood sugar on their own, so combined with your medication they could push your levels too low. Your diabetes meds might need adjusting, but that's something your prescriber has to decide.
Is this safe during pregnancy?
Not according to the safety data we have. Horsetail and skullcap should be avoided — there isn't enough data to know if they're safe. Stinging nettle also should be avoided. Oatstraw as a food is considered safe, but we hold limited data on concentrated supplement forms. Talk to your doctor before using this while pregnant.
Will this help my immune system?
The evidence we have doesn't really back that claim. The strongest proof is for oatstraw helping with cholesterol and heart health. For the others — horsetail, stinging nettle, skullcap, chamomile — the data says there's insufficient reliable evidence to rate how well they work for what you're hoping for.
What are the most common side effects?
Horsetail commonly causes belly bloating, more frequent bowel movements, and nausea. Stinging nettle can cause constipation or diarrhea. Skullcap may cause drowsiness, brain fog, and stomach upset. Oatstraw's fiber can bring on gas, bloating, and flatulence — these usually go away as your body adjusts if you increase the dose slowly.
Can I take this long-term?
Horsetail is meant for short-term use only — long-term use carries real risks, including thiamine deficiency if the product isn't certified free of thiaminase. Skullcap also has limited evidence for long-term safety. If you're thinking about using this regularly, check with your pharmacist first about how long is safe for you.
