What is beniseed?
Beniseed is the small seed of the sesame plant, Sesamum indicum. In Hausa it is called ridi. It is grown as a food crop across West Africa.
The seeds are eaten whole, roasted, ground into paste, or pressed for oil. In many homes they thicken soups and add a nutty taste. The young leaves are also cooked as a vegetable in some areas.
Here is the honest verdict. As a food, sesame is safe and nourishing for most people. As a remedy, the human evidence is thin and points to small effects on blood pressure and blood fats.
Long use in a tradition is not proof that something works. It is also not proof that it is safe. This page says so once, and then sticks to what is known.
How might beniseed work?
Most of the proposed action comes from its fats, fibre and plant compounds called lignans.
In cell and animal studies, the lignans sesamin and sesamolin appear to mop up free radicals and calm markers of swelling. Whether that happens in the human body at food amounts is not settled.
Sesame oil is high in unsaturated fat. Diets higher in these fats are linked to lower LDL ("bad") cholesterol. That is a general diet effect, not something unique to beniseed.
In small human trials, sesame seed or oil has lowered blood pressure by a few points. The trials were short and small. The reason for the change is not proven.
Whole seeds also carry fibre, which adds bulk to stool. That is a simple physical effect, and it is well accepted for fibre in general.
How is beniseed sold?
You will meet it most often as a food, not a pill. Common forms:
- Whole raw or roasted seeds, white, brown or black. - Ground seed paste, sold as tahini or as local beniseed paste. - Beniseed (sesame) oil, cold-pressed or toasted.
- Sweet cakes and snack balls made with the seed. - Dried or fresh leaves, cooked in soups. - Capsules of sesamin extract, sold as a supplement.
Toasted oil is a flavouring and is used in small amounts. Cold-pressed oil is used for cooking and on skin and hair.
What did tradition claim?
Beniseed has been grown and eaten in West Africa for centuries, and in Africa and Asia far longer.
In Hausa-speaking areas, ridi was pounded into soups, pressed for oil, and made into snack cakes. Cooks treated it as a strengthening food for new mothers and for people recovering from illness.
The oil was rubbed on dry skin and scalp. Seeds were also eaten to ease hard stools. Traders carried the seed widely, and it became a cash crop in northern Nigeria, Niger and beyond.
These were everyday food uses, recorded in cooking and trade rather than in trials.
Call emergency services at once if you get swelling of the lips, tongue or throat, a widespread rash, wheezing, or faintness after eating sesame. These are signs of anaphylaxis, a whole-body allergic reaction. Stop and see your doctor if you feel dizzy or faint after meals while on blood pressure medicine. Also see your doctor for low blood sugar signs such as shaking, sweating and confusion, or for lasting stomach upset.
Beniseed is an ordinary food, sold freely in most countries. In the United States, the European Union and the United Kingdom it is a named major allergen that must be declared on labels. Sesamin supplements are sold as food supplements and are not approved to treat any disease.
