Allicin, formed when onions are cut, has antiviral, antifungal, and antibacterial properties, boosting immunity and reducing inflammation. Quercetin, a powerful antioxidant, may improve sleep and protect cells from free radical damage. Onions also offer vitamin C and essential minerals like manganese and potassium, supporting overall health.
VOCs emitted by onions may be inhaled during sleep, potentially entering the bloodstream. While effects remain unclear, proponents believe this exposure can enhance health. Exploring these compounds provides a scientific basis for the experiment, blending traditional wisdom with modern evidence.
