What can go wrong
Multiple concerns. The ~40% alcohol base means these are consumed as spirits, with dependence and organ-damage potential; chronic use has been associated in recent studies with decreased hemoglobin and organ stress. Ingredients are variable and unregulated, some mixtures contain Aristolochia (aristolochic acid: documented nephrotoxin and carcinogen linked to urothelial cancer) or other toxic botanicals, and street 'manpower' preparations have been flagged by public-health authorities as dangerous unregulated aphrodisiacs. Undisclosed pharmaceutical adulteration is also a category risk.
This is something to take to a clinician. The Atlas can tell you what is known about west african herbal bitters in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
In West Africa, virility is a major driver of the herbal 'bitters' and agbo (Yoruba decoction) trade: alcoholic tonics such as Alomo Bitters and countless 'manpower'/'kokoro' mixtures are marketed to men for potency, stamina and libido. Typical botanicals include Mondia whitei (a well-known regional aphrodisiac root), Khaya senegalensis, Curculigo pilosa and other roots and barks, usually in ~40% alcohol. Human clinical evidence for aphrodisiac benefit is essentially absent, while documented hazards include the high alcohol load, unregulated dosing, adulteration, potential toxic botanicals (e.g., aristolochic-acid-containing plants linked to kidney failure and cancer), and reported effects such as reduced hemoglobin and organ stress with chronic use.

What people take it for
These are the reasons people give for taking it. They are not effects it has been shown to have.
How it is supposed to work
Traditional use rests on 'hot,' stimulating bitter roots believed to boost male vigor; Mondia whitei has some preclinical aphrodisiac and pro-erectile signals in animal models. The alcohol content itself produces disinhibition that consumers may misread as enhanced performance. No controlled human trial establishes an aphrodisiac effect for these bottled mixtures.
What people get wrong
Often saidA natural, safe way to boost manhood
ActuallyThese are ~40% alcohol unregulated mixtures with no clinical aphrodisiac evidence; some contain nephrotoxic/carcinogenic botanicals and carry real health risks.
Who profits, and who pushes back
Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.
How we got here
Bitters and agbo decoctions are deeply rooted in West African herbal practice; in recent decades commercial branded bitters (Alomo and many imitators) turned the virility angle into mass-market advertising across Nigeria, Ghana and the diaspora, blending traditional root medicine with modern alcoholic-beverage marketing.
What we do not know
- How prevalent is aristolochic-acid or pharmaceutical adulteration in commercial manpower bitters?
- Does Mondia whitei have any real human aphrodisiac effect separate from the alcohol?
Legal status
Sold in bars, kiosks, markets and by street vendors across West Africa, and exported to diaspora communities and online.
Status current as of July 2026. Regulatory positions change, sometimes quickly.
