HelloPharmacist Scorecard of Green Tea with Lemongrass 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 2 active ingredients.
  • “Proprietary Blend of Herbs” is a proprietary blend — the label doesn't break down how much of each component you get.

This product contains two active ingredients: green rooibos tea and lemongrass. Green rooibos is a naturally caffeine-free tea leaf with a naturally sweet flavor.

Lemongrass is an herb traditionally used in cooking and herbal beverages, known for its citrusy aroma. There are no other inactive ingredients listed.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish that either ingredient works for the conditions listed—age-related cognitive decline, hay fever, anxiety, cancer, heart disease, diabetes, headache, cold, cough, epilepsy, and fatigue all show insufficient reliable evidence to rate. This tea may be pleasant to drink, but we can't say it'll treat these conditions based on the data we have.

The evidence, ingredient by ingredient Rooibos Lemongrass

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Green rooibos tea is generally well tolerated when you drink it as a normal beverage. However, the facts note caution with concentrated extracts—they haven't been well studied, so check with your provider before regular use of extract forms.

Large, long-term doses of rooibos tea might cause liver problems in some people; one case reported hepatic dysfunction in a man drinking 10 cups daily for over a year. Lemongrass is likely safe in food amounts, but medicinal doses and essential oils have limited safety data.

Stick to occasional beverage use and avoid concentrated amounts without talking to your provider first.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Rooibos, Lemongrass.
  • The most serious interaction on file is rated Moderate.
  • For scale: 906 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.

This product is a pleasant herbal tea, but it affects how your liver processes many common medications.

Green Tea with Lemongrass by Mountain Meadow Herbs: Common Questions

Does Green Tea with Lemongrass by Mountain Meadow Herbs interact with any medications?
Yes. Based on its ingredients, Green Tea with Lemongrass has a known interaction with 905 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Green Tea with Lemongrass contains 2 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 this tea safe in pregnancy or while breastfeeding?
The safety information we have for both ingredients is incomplete—there isn't enough data to know either way. Talk with your doctor or pharmacist about whether this tea is right for you during pregnancy or breastfeeding.
Will this tea help with my blood sugar or prevent heart disease?
We don't have reliable evidence that either ingredient works for diabetes or heart disease. The research we hold rates both conditions as having insufficient evidence to rate these herbs as helpful.
Can I drink this tea every day?
As a regular beverage in normal amounts, it's likely fine—but if you take medications, especially ones processed by your liver, check with your pharmacist first. The facts caution against frequent medicinal use, and very large daily amounts over long periods may cause liver problems in some people.
What's the difference between this tea and a concentrated extract?
This product is a tea, which is safer and better studied than extracts or essential oils. Concentrated forms of both rooibos and lemongrass haven't been as well tested, so the caution is stronger for those—stick to your provider's advice if you're considering extracts.
