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 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.40 mL) without saying how much of each component you get.

Clark FX contains 4 active ingredients: a proprietary blend, clove, green black walnut, and green rooibos tea. Clove is included for its traditional aromatic and digestive properties.

Green black walnut and rooibos tea are plant-based ingredients with historical use in herbal formulations. The product also contains several inactive ingredients — vegetable glycerin, distilled water, vitamin C, and organic grain alcohol — that serve as carriers and preservatives in this liquid form.

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: Para-cleansing herbal formula everyday health.
  • We looked for evidence on: Crohn disease, Diarrhea, Dyspepsia, Flatulence, Gastritis, Nausea and vomiting — and 4 related terms.
  • The closest evidence on file: Rooibos is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).
  • Also on file: Clove is rated "Insufficient Reliable Evidence To Rate" for Diarrhea, Dyspepsia, Flatulence, Nausea and vomiting.
  • Also on file: Wormwood is rated "Insufficient Reliable Evidence To Rate" for Crohn disease, Dyspepsia.

The evidence backing these ingredients is limited. Clove shows possibly effective evidence for ventilator-associated pneumonia (a serious lung infection in hospitalized patients), but has insufficient reliable evidence for cough, acute pain, or indigestion.

Black walnut and rooibos tea both carry insufficient reliable evidence for their traditional uses — including heart disease, wound healing, and various other conditions we have data on. In short, we don't have solid evidence that Clark FX works for any condition in the usual way someone might use it at home.

The evidence, ingredient by ingredient Clove Black Walnut Wormwood Rooibos

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Clove is well tolerated in food amounts but can be toxic in medicinal doses or as concentrated oil; as little as 5-10 mL of clove oil has caused serious harm in children. The liquid form here raises the risk of accidental overdose if not measured carefully.

Common topical and inhaled adverse effects include burning, contact dermatitis, and mucous membrane irritation; serious but rare effects include liver failure. Green black walnut leaf, bark, and hull contain tannins that may cause stomach upset and skin irritation, and tree nuts can trigger allergic reactions in sensitive people.

Wormwood contains thujone, a neurotoxin; medicinal amounts can cause muscle aches, nausea, vomiting, and rarely acute kidney toxicity or seizures. Rooibos tea is generally safe in normal beverage amounts, though very large daily doses (10+ cups over a year) have been linked to liver dysfunction.

Clove is likely safe in pregnancy and lactation, black walnut is possibly unsafe while breastfeeding and should be avoided in pregnancy, wormwood should be avoided in both pregnancy and breastfeeding, and we hold insufficient data on rooibos use during pregnancy and lactation.

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?
  • 3 of the 4 matched ingredients can interact with medications — Rooibos, Clove, Wormwood.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; diabetes medications.
  • For scale: 1,043 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 Clark FX, double-check these medication types with your pharmacist: drugs metabolized by CYP enzymes (CYP2D6, CYP1A2, CYP3A4, CYP2C9, and CYP2C19 substrates), anticonvulsants for seizures, ACE inhibitors for blood pressure, atorvastatin and other cholesterol drugs, antidiabetes medications, and blood thinners or antiplatelet drugs. These interactions are documented as Moderate or Minor severity.

The bottom line

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

If you take any prescription medications — especially for seizures, blood pressure, cholesterol, bleeding, or diabetes — talk with your pharmacist before starting Clark FX; the interactions could be significant. If you're pregnant, nursing, or have a tree nut allergy, check with your provider first.

Clark FX by Mountain Meadow Herbs: Common Questions

Does Clark FX by Mountain Meadow Herbs interact with any medications?
Yes. Based on its ingredients, Clark FX has a known interaction with 1,042 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Clark FX contains 4 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 clove safe as an ingredient in this product?
Clove is safe in food amounts, but concentrated clove oil and medicinal doses can be irritating or toxic. Since Clark FX is a liquid blend, it's important to measure it exactly as directed and never exceed the recommended dose. If you have young children, keep it out of reach — even small amounts of clove oil can be dangerous.
Can I take this if I'm pregnant or breastfeeding?
Clove is likely safe during pregnancy and lactation. However, black walnut should be avoided in pregnancy and is possibly unsafe while breastfeeding. Wormwood should be avoided in both. Rooibos has insufficient data. Talk with your OB or midwife before starting — this product contains multiple ingredients with mixed safety profiles.
What is this product supposed to do?
The evidence supporting Clark FX's ingredients is limited. Clove has some evidence for a serious hospital-related lung infection, but there's insufficient reliable evidence for cough, pain, or indigestion — the conditions people often use it for. Black walnut and rooibos have insufficient evidence for their traditional uses.
What's in the bottle besides the active ingredients?
The inactive ingredients are vegetable glycerin, distilled water, vitamin C, and organic grain alcohol. These are carriers and preservatives that help preserve the product in liquid form.
Are there any side effects I should know about?
Clove can cause burning, itching, and mucous membrane irritation, especially when applied topically or in high doses. Black walnut may cause stomach upset and skin irritation due to tannins. Wormwood can cause nausea, vomiting, and muscle aches. Rooibos is generally well tolerated at normal beverage amounts, but very large daily doses have rarely caused liver problems.
Do I have a tree nut allergy risk?
Yes — black walnut is a tree nut and can trigger allergic reactions in sensitive people. Tree nuts are classified as a major food allergen in the United States. If you have a nut allergy or are unsure, ask your pharmacist before taking this product.
