HelloPharmacist Scorecard of Macuna pruriens (Brown Indian) Extract by Barlowe's Herbal Elixirs

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.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Mucuna pruriens seed extract, also called cowhage. It's a plant-derived powder containing levodopa, the same compound found in some Parkinson's disease medications.

Some commercial cowhage products are standardized to deliver 75–400 mg of levodopa per dose, though the exact amount in this formulation isn't specified on the label provided.

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

This is a single-ingredient Cowhage product and its label doesn't state a use — see Cowhage's own graded uses on its monograph.

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 cowhage works reliably for any condition we have data on. The ratings for anxiety, skin redness (erythema), high prolactin levels, muscle pain, Parkinson disease, and rheumatoid arthritis all show insufficient reliable evidence.

That means studies are either missing, too small, or unclear — not that it doesn't work, just that we can't say it does based on what's available.

The evidence, ingredient by ingredient Cowhage

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 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Oral cowhage is generally well tolerated, though a complete safety evaluation hasn't been done. The most commonly reported side effects are diarrhea, flatulence, and mouth irritation.

Some people in clinical trials experienced nausea, bloating, vomiting, headaches, or insomnia — a small number reported insomnia (about 3% in one trial). Because this product contains L-dopa, which affects dopamine and hormones, the safety data advises against use during pregnancy and while breastfeeding; L-dopa can lower prolactin and reduce milk supply.

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

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Cowhage.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: diabetes medications; Parkinson's medications.
  • For scale: 193 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 this product, check with your doctor or pharmacist if you take monoamine oxidase inhibitors (MAOIs), methyldopa, levodopa, antidiabetes drugs, antipsychotic medications, tricyclic antidepressants, guanethidine, or are scheduled for surgery requiring certain anesthetics. These carry Major or Moderate interaction risks with the levodopa this product contains.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This is a concentrated plant extract, not a mild dietary supplement — it contains levodopa, an active compound with real drug-like effects and serious interaction risks. If you take blood pressure medications, psychiatric drugs, diabetes medications, or MAOIs, you'll need to clear this with your doctor or pharmacist first.

Pregnant people and those breastfeeding should avoid it. Talk with your own healthcare provider about whether this fits your health picture.

Levodopa

Concomitant use can increase the risk of levodopa-related adverse effects.
Cowhage contains levodopa. Some cowhage products have been standardized to contain 75-400 mg of levodopa per dose.

Likelihood Likely Evidence D
Methyldopa (Aldomet)

Theoretically, concomitant use of cowhage and methyldopa might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with methyldopa might cause additive hypotension. In addition, methyldopa may inhibit peripheral decarboxylation of levodopa and increase levodopa levels in the central nervous system; avoid using.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use of cowhage and non-selective MAOIs might increase the risk of hypertensive crisis.
Cowhage contains levodopa. Use of levodopa with non-selective MAOIs might cause hypertensive crisis. However, this interaction has not been reported with MAO-B selective inhibitors such as selegiline.

Likelihood Probable Evidence D
Anesthesia

Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Cowhage contains levodopa. Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated. Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of cowhage and antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that cowhage might have hypoglycemic effects.

Likelihood Possible Evidence D
Antipsychotic Drugs

Theoretically, use of cowhage might decrease the clinical effects of antipsychotic drugs.
Cowhage contains levodopa. Use of levodopa might counteract the antidopaminergic effects of antipsychotic medications.

Likelihood Possible Evidence D
Guanethidine (Ismelin)

Theoretically, concomitant use of cowhage and guanethidine might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with guanethidine might cause additive hypotension; avoid using.

Likelihood Probable Evidence D
Tricyclic Antidepressants (Tcas)

Theoretically, use of TCAs might reduce the levels and clinical effects of cowhage.
Cowhage contains levodopa. Use of TCAs might reduce the absorption of levodopa. Some case reports describe patients that developed hypertension and dyskinesia when taking both levodopa and TCAs.

Macuna pruriens (Brown Indian) Extract by Barlowe's Herbal Elixirs: Common Questions

Does Macuna pruriens (Brown Indian) Extract by Barlowe's Herbal Elixirs interact with any medications?
Yes. Based on its ingredients, Macuna pruriens (Brown Indian) Extract has a known interaction with 193 medications, including 17 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Macuna pruriens (Brown Indian) Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is Mucuna pruriens and why is it in this product?
Mucuna pruriens, also called cowhage, is a plant seed extract that contains levodopa — the same active compound used in some Parkinson's disease medications. The product is sold as a supplement, though the evidence we hold doesn't establish that it reliably works for the conditions it's marketed for.
Can I take this if I'm pregnant or breastfeeding?
No — the safety data advises against both. The levodopa in cowhage affects dopamine and hormones in ways that aren't well understood in pregnancy, and while breastfeeding it can lower prolactin levels and reduce milk supply. Talk with your doctor if you're considering it.
What are the side effects I might expect?
The most common are diarrhea, gas, and mouth irritation. Some people report nausea, stomach bloating, vomiting, headaches, or trouble sleeping — a small number experienced insomnia in clinical trials. Because it contains an active drug-like compound, it should be used carefully and under professional guidance.
Is this safe to use with my other medications?
That depends entirely on what you take. This product interacts with many medication types — blood pressure drugs, psychiatric medications, diabetes drugs, and others — some seriously. Check your specific medications with the tool on this page, then talk with your doctor or pharmacist before starting.
How much levodopa is in each dose?
The product label provided doesn't specify the levodopa content. Some cowhage products are standardized to 75–400 mg per dose, but we can't tell you what this particular powder contains without seeing the full label or manufacturer information.
