HelloPharmacist Scorecard of Mucuna pruriens Extract by BulkSupplements.com

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. Cowhage is a plant seed that naturally contains levodopa (L-dopa), a compound your body converts to dopamine, the chemical that helps control movement and mood.

The amount of levodopa in cowhage products is not standardized and can range from 75 to 400 mg per dose, depending on how it's processed. There are no inactive ingredients listed for this powder.

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 for cowhage's effectiveness against the conditions listed — anxiety, certain skin reactions, high prolactin levels, muscle pain, Parkinson disease, and rheumatoid arthritis — is insufficient to establish whether it works. While cowhage does contain levodopa, a well-studied Parkinson drug, the data we hold does not support a rating for cowhage itself for any of these uses.

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.

Orally, side effects from cowhage are generally rare, though a complete safety evaluation has not been done. The most commonly reported gastrointestinal effects are diarrhea, flatulence, and mucosal irritation; some people also report dry mouth and headaches.

In research with a specific cowhage extract at higher doses (22.5 to 67.5 grams daily), a small number of trial participants reported nausea, abdominal bloating, vomiting, and insomnia. The safety data advises against use during pregnancy because there isn't enough information and cowhage's dopamine effects raise concerns.

Avoid cowhage while breastfeeding — levodopa can lower prolactin (a hormone that supports milk production) and may reduce your milk supply.

Mucuna Pruriens Seed Extract8 drug types · 193 drugs

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.

Mucuna pruriens Extract by BulkSupplements.com: Common Questions

Does Mucuna pruriens Extract by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Mucuna pruriens 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?
Mucuna pruriens 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 cowhage and why does this product contain levodopa?
Cowhage is a plant seed that naturally contains levodopa, a compound your body converts to dopamine — the chemical that affects movement, mood, and other brain functions. The amount of levodopa varies depending on how the extract is processed, ranging from 75 to 400 mg per dose.
What side effects might I experience from this powder?
Mild digestive upset — diarrhea, flatulence, and stomach irritation — is most common. Headaches, dry mouth, and insomnia have also been reported, especially at higher doses. A thorough safety evaluation hasn't been completed, so other effects may exist.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advises against use in pregnancy because there isn't enough information and cowhage's dopamine effects raise concerns. While breastfeeding, avoid it — levodopa can lower prolactin and reduce your milk supply. Talk with your doctor about what's appropriate for you.
Is this powder proven to work for Parkinson disease or anxiety?
The evidence in our data is insufficient to establish whether cowhage works for Parkinson disease, anxiety, or any of the other conditions listed. Although cowhage contains levodopa (which is used for Parkinson disease), we don't have reliable evidence for cowhage itself.
Why do I need to tell my pharmacist I'm taking this before surgery?
Cowhage contains levodopa, which can interact with certain anesthetics — specifically cyclopropane and halogenated hydrocarbons — and may cause irregular heartbeats. Your anesthesiologist needs to know you're taking this so they can choose a safe alternative anesthetic.
Does this product contain any fillers or other inactive ingredients?
According to the product facts, no inactive ingredients are listed for this powder.
