Okoho is the stem of Cissus populnea, a climbing vine of West Africa. Peeled and soaked in cold water, it gives a thick, slippery liquid. Yoruba speakers call the plant ajara; Hausa speakers call it dafara.
The stem has two lives. In Benue State, Nigeria, Idoma cooks use the slime to draw okoho soup, so it is a food. Elsewhere the same soak is drunk as a tonic, mostly by men hoping to boost sex drive or fertility.
Here is the honest verdict. Tradition is not proof that a remedy works, and it is not proof that it is safe. Almost all okoho research is in rats and test tubes, so the fertility claim rests on custom, not on human trials.
Nobody has shown what okoho does inside the human body.
The stem is loaded with mucilage (a thick, slimy gum made of plant fibre). Fibre like this swells in water and coats the gut. In theory that can slow how fast sugar is taken up after a meal, which is why gut and blood sugar claims are made.
Rat studies are the main source of the fertility story. Some found that stem extracts raised testosterone and sperm counts in male rats. Other rat work found harm to sperm at higher doses, so the animal picture itself is mixed.
In test tubes, extracts slow the growth of some bacteria and mop up free radicals (unstable molecules that damage cells). Animal wound studies suggest faster skin closure. Whether any of this happens in a person who drinks the soak is not established.
Treat every mechanism above as a lead, not a finding. None has been confirmed in people.
Okoho reaches people in several forms.
- Fresh or dried stem pieces, sold in bundles in West African markets - A cold-water soak of the peeled stem, drunk or stirred into soup - Dried stem ground to powder, sometimes sold in capsules - Mixed herbal "man power" tonics, often with alcohol and other herbs
The soup and the plain soak are the traditional forms. They are what most long-term users have actually taken.
Mixed tonics are the form to be most careful with. You cannot tell what else is in the bottle. Herbal sex tonics as a group have repeatedly been found spiked with prescription erection drugs.
Okoho has a long, well documented record across West Africa.
Herb sellers in Nigeria, Ghana and Benin offered the soaked stem for male sexual weakness and infertility. Others gave it for wounds, joint pain, stomach upset and as a general tonic.
Among the Idoma people of Benue State, okoho soup was an everyday dish. It was also served to women after childbirth and to people recovering from illness. The slippery texture was valued for its own sake.
Most written records come from plant surveys and market studies of the last hundred years. Those surveys show how widely the stem was used. They were never designed to test whether it helped.
Stop and get medical help the same day if you have a rash, swelling of the lips or face, or trouble breathing.
Also stop and see a doctor if you get: - severe stomach pain, or vomiting that will not stop - shaking, sweating or confusion, which can mean low blood sugar - yellow eyes or skin, or dark urine - unusual bruising or bleeding
Go to an emergency department for chest pain, fainting, or an erection lasting more than four hours after taking a herbal tonic.
In Nigeria the stem is an ordinary market food, and packaged herbal products must be registered with NAFDAC. In the United States it may be sold as a dietary supplement, with no approval for treating anything. In the UK and EU it is not an authorised medicine and has no novel food clearance, so legal sale as a supplement is doubtful.
