Introduction: Spring onions can be classified into purple spring onions and white spring onions based on the color of their outer skins. White spring onions have white outer skins. The flesh of white spring onions is white, round or oval, with high water content and coarse texture, providing a crispy mouthfeel and a distinct pungent taste. Spring onions are rich in nutrients and have a strong aroma. They can stimulate the secretion of gastric, intestinal, and digestive glands, improve appetite, promote digestion. Spring onions are fat-free and contain a mixture of sulfur-containing compounds in their essential oils, which can lower cholesterol levels. They can be used to treat indigestion, loss of appetite, and stagnation of food. Spring onions have the ability to dispel wind and cold. This is because the bulbs and leaves of spring onions contain an oil-like volatile substance called allyl sulfide, which has a pungent taste. This substance can resist cold, defend against influenza viruses, and has strong antimicrobial properties.
