Pako ijebu is a chewing stick cut from the stem or root of Massularia acuminata, a West African shrub. You chew one end until it frays into soft bristles. You then rub that frayed end over your teeth and gums.
The name is Yoruba and the stick is best known in southwest Nigeria. Sellers offer it in bundles at markets and roadsides. Shops and websites also sell the bark or root as a powder, a liquid extract or capsules.
Here is the honest verdict. Chewing sticks can clean teeth fairly well, and that use is widely accepted. Claims about strength, fertility and sex drive come from rat studies, not from human trials.
Long use in a tradition shows a plant is valued and trusted. It does not prove that the plant works, and it does not prove that it is safe. That point applies to everything on this page.
Most of what the stick does is mechanical. The frayed fibres act like bristles and scrape soft plaque off tooth surfaces. Chewing also makes you produce more saliva, which helps rinse the mouth.
The plant chemistry may add something on top of that. In laboratory tests, extracts of Massularia acuminata slow the growth of some mouth bacteria, including the ones linked to decay. Whether that happens in a real mouth, at the amount released by chewing, has not been shown.
The body claims rest on animal work. In male rats, root extracts raised testosterone, sperm counts and mating behaviour. Rats are not people, and no human trial has tested this.
Animal studies have also reported lower blood sugar and some pain and fever relief. Again, these are rodent findings. Treat them as leads, not as proof of what the plant does in you.
The traditional form is the stick itself. Common forms you may meet:
- Fresh cut sticks, sold in bundles - Dried sticks, often sold in packs for export - Chopped bark or root for brewing as a drink - Powders and capsules sold as supplements - Liquid extracts, sometimes mixed into local herbal drinks or spirits - A listed ingredient in some herbal toothpastes and mouth rinses
The stick is the only form with a plausible everyday use. Powders, capsules and drinks concentrate the plant far beyond what chewing gives you. Those forms are the ones with almost no human safety data.
Chewing sticks have been used across West Africa for centuries, long before toothbrushes arrived. Massularia acuminata was one of the woods people favoured in what is now southern Nigeria. The Yoruba name pako ijebu points to the Ijebu area.
Users valued the stick for clean teeth, firm gums and fresh breath. Many people kept one in the mouth through the morning. The bitter taste was seen as part of the benefit.
Herbal practitioners also used the bark and root in other ways. Recorded uses included drinks for fever, aches, stomach trouble and male sexual weakness. These were traditional practices recorded by observers, not tested treatments, and this page is not a guide to repeating them.
Stop and see a dentist or doctor if any of these happen:
- Tooth pain lasting more than two days, or pain that wakes you - Swelling of the gum, jaw or face, or pus around a tooth - Gum bleeding that does not stop within a few minutes - Teeth that feel notched, sharply sensitive, or look longer than before - A splinter stuck in the gum that you cannot remove - A mouth sore or white patch that lasts more than two weeks
Get urgent care for facial swelling with fever, or swelling that makes it hard to swallow or breathe.
In Nigeria and nearby countries the sticks are sold freely as an ordinary market item. In the UK, the EU and the US they are sold as a cosmetic oral care item or a food supplement. No regulator has approved this plant as a medicine, and supplement makers are not required to prove that it works.
