While onions are a staple in culinary practices worldwide, their benefits extend far beyond enhancing the flavors of our meals. Known for their pungent aroma and potent compounds, onions have historically been regarded for their health and healing properties. Recently, people have rediscovered an intriguing use for onions: air purification. Placing a slice of onion in a room is said to cleanse the air of toxins and impurities, improving air quality and offering health benefits right where you live.
Historical Use of Onions for Health and Wellness
Onions have been used for millennia not just as a food ingredient but also for medicinal purposes. Ancient Egyptians revered onions, believing their spherical shape and concentric rings symbolized eternal life. In traditional medicine across various cultures, onions were prescribed to reduce inflammation, boost immunity, and even ward off infections. During the 16th century, onions were used to protect against the bubonic plague, although this belief lacked scientific evidence, demonstrating the longstanding faith in their protective qualities.
Understanding the Science Behind Onions and Air Purification
Recent interest in onions’ purification properties has led to scientific investigations into how this humble bulb can cleanse the air. Onions contain sulfur compounds, including thiosulfinates, which have antimicrobial properties. When an onion is cut, these compounds are released into the air. While more research is needed to fully understand the extent of air purification onions can provide, initial studies suggest these compounds may help reduce airborne microbes, thereby improving air quality.
