Muira Puama Extract: Yours Is Probably Wrong & How to Get The Real Benefits

The plant chemicals you want may not be in your muira puama extract. Stems from a different tree are frequently sold as muira puama.

This article include all benefit findings and eight checks before you buy so you get authentic muira pauma extract.

What to look for in a muira puama extract

Before you buy muira puama extract, use this full checklist if you want the real plant.

1. Botanical name: Ptychopetalum olacoides (or P. uncinatum) written on the label. “Muira puama” alone isn’t enough.
2. Plant part: root, or root and stem bark, stated. Bark-only labels with no species is a red flag.
3. Solvent: water, ethanol or a water-ethanol mix. These are the methods documented in patents and the one characterized lab extract.
4. Ratio and amount: milligrams of extract per capsule, with the ratio. A ratio alone is meaningless.
5. Marker: a named marker such as magnoflorine or menisperine. Almost no consumer label gives one.
6. Testing: a named lab, or an NSF Contents Certified or USP Verified seal, plus a batch certificate of analysis. “Third-party tested” with no lab named means little.
7. Single herb or blend: every ingredient amount disclosed. A proprietary blend can hide a token amount of muira puama.

The short version

• What it is: an extract of Ptychopetalum olacoides, a small tree from Amazona called potency wood. Traditional use is real.
• Human evidence: all studies tested a blend, never muira puama alone. Benefits for men and women are limited, uncontrolled and confounded. No human data for Testosterone, memory and mood.
• Dose: arond 125 mg inside a blend to 1,500 mg a day, and each figure describes a different preparation. Follow the label.
• Ratios: 4:1, 10:1 or 20:1 tells you how much herb inside. Says nothing about how strong it is.
• Safety: Pregnancy and breastfeeding safety isn’t established. Interactions with cholinesterase inhibitors, antidepressants and yohimbine are theoretical. France lists the root and stem bark on its “adverse effects may outweigh benefit” list.

What muira puama extract is

The plant

A small tree from the Amazon with fragrant white flowers. The main species is Ptychopetalum olacoides Benth., family Olacaceae. Grows in Brazil, French Guiana, Guyana and Suriname.

Names keep showing up: potency wood, marapuama, muirapuama, muiratam, pau-homen, and Potenzholz in German.

Two lookalikes are sold and why some people get no benefits:

• P. uncinatum Anselmino is used interchangeably. It has less lupeol, with no numbers attached.
• Liriosma ovata Miers is also sold as muira puama. Patents treat it as a stand-in, but whether it’s a true synonym is unresolved, and a 2005 herbal handbook says its chemistry differs.

Traditional Use

European interest can be traced back to the 1930s when it was promoted as a male stimulant. Found in Brazils pharmacopoeia in 1956. The British Herbal Pharmacopoeia listed it for dysentery and impotence.

Muira puama bark or root: which part is used?

Muira puama bark and muira puama root aren’t the same. There’s a dissagrement on which part to use.

Tyler’s Honest Herbal names stem wood and root, a 2005 handbook names root and bark, Tian’s chemistry paper used bark, and Trindade’s extract used root.

The plant is wild-harvested. Brazilian sources report overharvesting has reduced natural populations, and an Embrapa conference record is titled around a muirapuama “at risk of extinction”.

Extract types compared

Muira puama tea: does a decoction count?

Muira puama tea is a decoction: root or bark simmered in water. It’s the oldest form. Brazilian sources describe infusions and medicinal baths from the root. Duke records one cup of root-bark decoction a day, with no cup size or bark weight given. Water gives a different extract from the ethanol ones in the patents. Nobody has tested tea for any effect.

What’s Inside

What the research shows

Every verified human study on record tested a blend, not muira puama alone.

The 2018 pilot comes from a UCLA group that has published a whole series on the same blend. Two more of their studies are registered on ClinicalTrials.gov.

Muira puama benefits for men

Men take it for desire and erections. The support is the 54-man blend pilot above, plus unverified 1990s French reports covered below.

Muira puama benefits for women

The whole human record is the 202-woman survey above. With no placebo group, a benefit can’t be separated from the ginkgo or from expectation.

What about the “262 men” and “100 men” numbers?

You’ll see “262 men, 1 to 1.5 g a day, about 60% improved libido” attributed to Waynberg in 1994. The paper exists as a record (“Yohimbine vs. muira puama in the treatment of sexual dysfunction,” Am J Nat Med 1994;1:8–9). Its text couldn’t be retrieved. The numbers online come from retailer pages and disagree with each other.

A 2005 herbal handbook cites two French reports. One covers 262 men. The other covers 100 men on 1.5 g of extract a day, with 85% reporting more libido. Both are subgroup self-reports with no placebo, no blinding and no stated duration, cited from a 1990 conference talk and a 1995 item with incomplete details.

Does it raise testosterone?

No data say so. No human or animal study measuring testosterone, LH or FSH after muira puama alone turned up in PubMed. A 2025 rat preprint claims a rise, but it doesn’t describe the extract, contradicts itself on methods and isn’t peer reviewed.

Lupeol, a compound sometimes listed in the plant, inhibited androgen receptor activity in prostate cancer cells and mice. That’s a different setting and says nothing about people taking the plant. But it gives a testosterone claim no support. A docking study found eight muira compounds that fit estrogen receptors in a computer model. That’s a hypothesis, not a finding.

Can you trust the long lists of “actions”?

Often not, because they mix evidence of different strength. Duke lists 18 properties for lupeol, including antitumor, antiviral and antimalarial, and an anti-inflammatory activity of “1/3 indomethacin” with no assay stated. A property of an isolated compound doesn’t transfer to an extract holding an unknown amount of it. For scale, a topical Liriosma ovata extract ran about 8 times weaker than indomethacin in a mouse ear test.

The 2005 handbook’s hypotensive claim leans on a rabbit study of a different species, Liriosma ovata. Keep three categories apart: root-extract findings, historical whole-herb claims, and isolated-compound activities.

Evidence grade by claimed use

Primary sources in Chinese, Russian, and some French and Japanese databases weren’t reachable, so they aren’t covered here.

Dosage: why sources disagree

You’ll find five or more dose figures online. They look like they contradict each other. They don’t, because each describes a different preparation.

Why no dose is established

The human studies are blends, so a muira dose can’t be isolated. The extracts differ, so 1.5 g of one study extract, 2–4 mL of a tincture and a 4:1 capsule aren’t shown to be equivalent. The best-known single-herb figure can’t be traced to a primary paper, and the only controlled-design data are animal doses, which don’t convert. Duke’s entry has no dose in mg of dry extract, no solvent percentage and no standardized lupeol percentage. So nobody, this article included, can give you a number backed by high-quality human research.

Label rule

Follow the product label and check with a clinician before you start, especially if you take medication or have a health condition. If you try it anyway, keep the trial short. The only dose figure here with a time frame, from Natural Medicines, covers one month.

Muira puama side effects and safety

There’s little safety data, and that’s different from showing the plant is safe.

• What was observed in people. A 28-day Catuama study reported no severe reactions or lab changes. In the Revactin pilot, 5 of 54 men reported mild dyspepsia, heartburn or migraine.
• Reassuring-sounding ratings. Duke gives it his “++” rating, roughly “as safe as coffee,” and cites an American Herbal Products Association class 1 rating, but calls the symbol subjective. The 2005 handbook lists “none reported” for cautions, based on what was known then. Tyler’s Honest Herbal rated safety inconclusive.
• A flag from the other side. As of July 2007, the FDA Poisonous Plant Database held two titles referring to possible toxicity of this species. Duke doesn’t identify them. That proves nothing, but it can’t be skipped either.
• Not found: pharmacokinetics, chronic toxicity, liver or kidney studies, genotoxicity, and any pregnancy or breastfeeding data. Brunetti’s 2020 review concluded that most herbal sexual enhancers appear safe at normal doses, with drug interactions and unstandardized products as the bigger worry. Whether muira puama is among the plants covered couldn’t be confirmed.

Is it safe in pregnancy or while breastfeeding?

Safety isn’t established. WebMD and the Natural Medicines database advise avoiding it. No data means no data. It isn’t evidence of harm, and it isn’t permission.

Who should talk to a doctor first?

Anyone on medication or with a health condition. Persistent erectile problems can signal cardiovascular disease or diabetes, and herbal references say so directly. A capsule isn’t a diagnosis.

What about interactions?

Nothing has been tested in people. These concerns are theoretical, but they follow from animal data:

• Cholinesterase inhibitors such as donepezil. Oral doses inhibited acetylcholinesterase in mouse brain, so stacking is a concern in principle.
• Antidepressants and other mood medication. The antidepressant-like effect in mice involved catecholamine pathways.
• Yohimbine. In Duke’s experiment the extract increased yohimbine-associated lethality in the animal model. No safe interval is known.
• PDE5 inhibitors. Seven patients in the 2026 blend series were on them, but no interaction was assessed.
• Blood pressure drugs. The hypotensive claim is weak, so treat this as an open question, not a documented effect.

How to choose a muira puama extract

See our recommendation at the beginning if you want the real thing.

Which form is best?

No form has trial support, so this ranks quality, not proven effect. Best documented is an ethanol-water root extract with species, plant part, named marker and batch COA, and no consumer product found meets all of it.

The same without a marker is acceptable if the seller supplies a COA with identity testing. A tincture has unknown potency. Plain powder is weakest, because it’s the lowest concentration and the easiest place for a substitute to hide. Skip proprietary blends, ratio-only labels, “clinically proven” with no citation, and prices far below raw-material cost.

Which marketing claims should you ignore?

Muira puama and damiana, maca root or ashwagandha: what’s been tested?

People stack muira puama with other herbs. Here’s what the research holds for each pairing.

Stacking multiplies the unknowns. Muira puama alone has no established dose and no interaction data, so a mix has neither. Even the blends that were studied, Catuama and Revactin, couldn’t separate muira puama’s contribution from the other ingredients.

Damiana and blue lotus together, as tea or any other form, aren’t covered by anything here. For the lotus half, see our blue lotus guide.

Muira puama extract vs muira puama and catuaba

Plain muira puama is the root, bark or wood. The extract is a processed form of it. They aren’t interchangeable, because processing changes what you get and the label may not tell you how.

Catuaba is a different tree, often paired with muira puama. The papers call it T. catigua. Catuaba bark and catuaba extract are sold on their own too, but none of the trials above tested catuaba alone. The Brazilian herbal product Catuama combines guarana, catuaba, muira puama and ginger, so a Catuama result belongs to the blend.

Take the one catuaba finding in this research. Catuama reverted ventricular fibrillation in an isolated rabbit heart, and the authors credited mainly T. catigua. That’s tissue work with no bearing on catuaba benefits in people. A 2024 review of Brazilian plants for male sexual dysfunction also notes adulteration of catuaba and calls for standardization, so substitution isn’t unique to muira puama. No source covers catuaba and damiana together.
