6 Surprising Ways to Use Onions Other Than Cooking With Them!

Onions are one of the most versatile ingredients in the kitchen. They are used in almost every Indian dish - be it in curries to add a depth and pungent kick or as a crunchy, fried topping for biryanis. They easily merge with different flavours and yet add their own distinctive taste that can set your dish apart. Not only are onions popular as a cooking ingredient but they are also known for their healing properties. They are a good source of biotin and also contain other essential micro-nutrients such as manganese, copper, vitamin C, potassium and folate. While you may have known all this, there's a lot more to explore with this extremely useful ingredient. Here are six surprising ways to use onions that no one probably told you. 1. For hair growthOnion juice is one of the best home remedies to fight hair fall and boost hair growth. Onions contain sulfur that boosts collagen production in the tissues and helps in the re-growth of hair. Hair fall is also often caused due to the absence of high sulfur proteins which leads to breakage and makes your hair strands fragile.

2. Repel insects and soothe bitesThis may sound a bit revolting as no one really likes the smell of onion, but rubbing a slice of it on your skin acts as a natural insect repellent. Not only this, onion juice can also help in soothing the pain caused by insect bites. Onions slices are often rubbed on bee stings to soothe the pain and prevent swelling. 3. Clean rusty knivesHave lots of rusty knives lying around in the kitchen? Here's how you can clean them. Slice an onion and rub it all over the knife and on the rusted part. Rust is made up of hydrogen ions, and onions contain a chemical called sulphanilic acid that reacts with these hydrogen ions to break up rust and make your knives shine again.
