The onion is often used as a home remedy for a cold or earache. The reason for this is the antibacterial ingredients that can reduce inflammation.

The vegetables owe their sharpness to the essential oils they contain. The fact that chopping onions makes us cry is due to two substances in the onion cells that are released during cutting, react chemically with each other and form a substance that is irritating to the eyes.
Healthy effect of the onion
The ingredients in onions can contribute to health in different ways.
Onions protect against the flu: The raw onion contains so-called fructans, fructose compounds that serve as carbohydrate stores. Studies have shown that these fructans fight the flu virus. The vitamin C contained in the onions and the antibacterial power of the sulfur compounds in the onion should also help the defense. Warning: fructans have a flatulence effect on some people. For this reason, raw onions should only be eaten in moderation, despite their health-promoting effects (a maximum of one per day).
Onions act as pain relievers: According to studies, the sulfur-containing ingredients of the onion have a similar effect to the acetylsalicylic acid (ASA) known from pain relievers: They accelerate the blood flow and thus supply the bloodstream with oxygen. This can not only help against tension headaches, but also prevent thrombosis and strokes.
Onions lower the risk of cancer: The onion is rich in valuable antioxidants. These protect the body’s cells from harmful substances. Various studies have also found that people who eat onions frequently are less likely to develop cancer.
Onions help with diabetes: Diabetes patients also benefit from the effects of the plant substances in onions: their flavonoids lower blood sugar and blood lipid levels. This helps to prevent secondary diseases of the heart.
Onions support digestion: Fiber in the onion is important for a healthy intestinal flora. The bacteria in the intestine (microbiome) need such prebiotics as food. A healthy intestine, in turn, has a positive effect on the immune system. However, raw onions can cause gas. Slowly getting used to the vegetables can prevent this.
Onions are good for the heart: Onions can lower blood pressure and cholesterol levels and, thanks to the substance allicin, have a vascular protective effect. You can thus prevent atherosclerosis, which is often the cause of a stroke or heart attack.
Onions can help prevent osteoporosis: According to studies, consuming onions daily can have a positive effect on bone density. In addition, the fiber it contains promotes the absorption of calcium, which is of great importance for building bones.
Onion as a home remedy
The onion is used as a home remedy for various diseases.
Onion sachets for earache: Thanks to its anti-inflammatory properties, the onion helps with earache caused by, for example, an otitis media. To do this, cut the onions into cubes, heat them briefly in a microwave or by frying them and then fill them in a cloth or sock. Then place the warm bag (can also be used cold) on one ear. It can be attached with a headband or a hat.
Onion cough syrup: Homemade onion juice can help resolve coughs. To do this, cut the onions into small pieces and mix them with brown sugar (alternatively honey). After a few hours you will get onion syrup, of which a teaspoon can be taken several times a day.
Storage of onions
Onions can be stored for several weeks to months in winter without any problems if they are kept dry, dark and airy (not wrapped in foil). Sliced onions should only be packed airtight in the refrigerator. Otherwise they will transfer their intense taste to everything around them. Put the cut side down in a storage box and close it. Onions can be kept for a few days in the refrigerator. If raw onions are too hot for you anyway: when steamed, they taste milder and almost sweet.
