These nutrient-dense beans have been used for centuries in West African cuisine and traditional medicine. Packed with protein, fiber, and various vitamins and minerals, locust beans offer many health benefits.

It helps reduce oxidative stress in the eyes and minimizes damage to lens tissues and photoreceptors in the retina.

Controls Blood Pressure

Locust beans are rich in potassium but low in sodium. Potassium helps lower blood pressure by reducing the effects of sodium in the body. Potassium works by relaxing the blood vessels and easing the flow of blood. It also helps the kidneys eliminate excess sodium through urine.

Eating more locust beans and other potassium-rich foods is an easy and natural way to help regulate your blood pressure. By replacing some of the sodium in your diet with potassium, you may be able to lower your blood pressure by a few points. The combination of increased potassium and reduced sodium is particularly helpful for maintaining healthy blood pressure levels.

Eating locust beans can help you feel full for longer periods, reducing appetite and calorie intake. The fiber in Iru also helps promote satiety, the feeling of fullness. This combination of protein, fiber and healthy fats is excellent for weight loss and maintenance.

Treats Diarrhea

Locust beans contain tannins, saponins, and alkaloids that give it antidiarrheal properties. The tannins in locust beans act as antisecretory agents that reduce fluid loss in the intestines. The saponins also have anti-secretory effects and soothe the intestinal lining.

The alkaloids in locust beans slow down movement in the intestines, allowing for better absorption of fluids and electrolytes. This helps prevent dehydration from diarrhea and restores balance in the body.

In many West African cultures, locust bean concoctions are used to treat diarrhea in both children and adults. Locust beans can relieve diarrhea and the abdominal cramps that often accompany it. The antidiarrheal and gut-soothing effects of locust beans make it an effective natural remedy for diarrhea.

Controls Blood Sugar Level

Locust beans have compounds that can help regulate blood sugar levels. They are rich in fiber that helps slow down sugar absorption into the bloodstream. This prevents blood sugar spikes and crashes, keeping levels stable. The beans also contain compounds like leucine that can increase insulin sensitivity, allowing cells to uptake more glucose.

For diabetics and prediabetics, locust beans may aid blood sugar control and reduce the risk of complications when consumed regularly. The soluble fiber forms a gel that traps carbohydrates, slowing digestion and the conversion of carbs into sugar. This gives the body more time to produce insulin to escort the sugar out of the bloodstream. Locust beans are not a substitute for diabetes medication but can be part of an overall diet and lifestyle plan to manage high blood sugar.

Wound Healing Properties

The seeds of Locust beans contain compounds like alkaloids, flavonoids, and tannins which give it wound healing abilities. These compounds have antimicrobial properties that can prevent infection and accelerate the healing of wounds, ulcers, and burns.

Locust beans also promote the growth of new cells and tissues. When applied to the skin, the oils and extracts from the seeds can speed up the process of closing wounds and regenerating skin. The flavonoids in particular improve blood circulation to the applied area, which provides more oxygen and nutrients to fuel the healing process.

For minor cuts, scrapes, and wounds, you can create a paste from the ground seeds and apply it directly to the skin. The paste can help stop bleeding, reduce inflammation, and promote healing. For more serious wounds, the ground seeds can also be boiled in water to make a decoction. Allow it to cool, then use as a wash or poultice on the wound.

The wound healing ability of locust beans has been known and used traditionally for centuries. Modern research has validated many of the traditional uses, showing that locust beans deserve a place in your natural first aid kit.

This can provide relief from respiratory infections like the common cold, bronchitis, and pneumonia.

Locust beans also have natural anti-inflammatory and antioxidant properties which can help reduce inflammation in the respiratory tract. The antioxidants help strengthen the immune system and may help shorten the duration of respiratory infections.
