The Hidden Power of Onion Peels: Benefits and Homemade Uses
Most people throw away onion peels without a second thought — yet these papery layers are one of the most overlooked sources of nutrients in the kitchen. Beneath their dry exterior lies a treasure of antioxidants, vitamins, and bioactive compounds that can help support health, improve skin, strengthen the immune system, and even benefit plants. Whether you prefer red, yellow, or white onions, their peels can be used in several practical and healing ways at home.

They also contain phenolic compounds, fiber, and sulfur compounds, all of which contribute to better overall wellness. These elements work together to fight free radicals, support cardiovascular health, and protect the body from chronic inflammation.
