Onions are incredibly versatile and have various uses beyond being used as a culinary ingredient
1. Onions contain natural antibacterial and antiseptic properties. Rubbing a cut onion on surfaces can help remove bacteria and sanitize the area
2. Onions can be used as a natural insect repellent. Placing onion slices or onion juice near entrances and windows can help keep insects, such as flies and mosquitoes, away
3. The acidic properties of onions make them effective for polishing metal surfaces. Rubbing a cut onion on metal objects, like copper, brass, or stainless steel, can help restore their shine.
4. Onions possess anti-inflammatory properties. Applying a slice of onion or onion juice to the affected area or insect bites may provide relief and reduce swelling.
