We value the culinary virtues of onions, we remember them when the infection season approaches. However, it is no secret that the true wealth of natural health-promoting ingredients is hidden not so much in the successive layers of the vegetable, but in the skins. Unfortunately, these usually end up in the trash, even though they are a source of an ingredient that we line up for at the pharmacy in the form of a supplement.

Why shouldn't you throw away onion skins? Mainly because of the quercetin present in them, a bioactive plant compound with antioxidant properties. It turns out that quercetin is also essential for healthy antibody growth, fighting infections. Onion skins are also a valuable source of vitamins, trace elements such as calcium, magnesium, iron, potassium, selenium, or chromium, sulfur compounds, and dietary fiber.

Quercetin - a wonderful substance enclosed in onion skins

It's worth taking a closer look at the aforementioned quercetin. You can find supplements in pharmacies where this compound is an ingredient, but the form found in onion peels is better absorbed. Quercetin is a powerful antioxidant - it helps the body fight off free radicals, which contribute to many diseases. Thanks to its anti-inflammatory properties, quercetin helps to alleviate inflammation in the body. This is significant in the case of chronic diseases, such as heart disease, diabetes, or cancer.

Quercetin is also known for improving cardiovascular health. It helps in lowering the level of bad cholesterol in the blood and regulates blood pressure, thereby reducing the risk of heart diseases. Furthermore, this substance improves the elasticity of blood vessels, preventing blood clots and strokes.

Another significant advantage of quercetin is its ability to support the immune system. It acts like a "shield", strengthening the body and helping in the fight against viral and bacterial infections. Therefore, it is worth taking advantage of beneficial infusions made from onion skins during the flu season.
