What are the medicinal values ​​of onions?

I believe that we often use onions in our daily lives, especially when we eat some cold dishes, noodles, wontons and dumplings, onions will always appear in the seasonings. From this we can see that onions can not only increase our appetite, but are also said to have very good defensive and therapeutic effects on colds. Therefore, we know that onions also contain many medicinal values. So what are the medicinal values ​​of onions? Let us discuss it together.

1. Raw onions, like onions and scallions, contain allyl sulfide. Allyl sulfide stimulates the secretion of gastric juice and helps increase appetite. When taken together with foods rich in vitamin B1, the starch and sugar contained in vitamin B1 will convert into calories, thereby enhancing the effect of relieving fatigue.

2. The green part of onion contains more vitamin A, vitamin C and calcium than the white part. Onions contain a considerable amount of vitamin C, which can dilate small blood vessels and promote blood circulation. It helps prevent dizziness caused by high blood pressure, keeps the brain flexible and prevents Alzheimer's disease.

3. People who often eat onions, even if they are fat, do not have high cholesterol and have a strong physique. Onions contain the trace element selenium and can reduce the nitrite content in gastric juice, which plays a certain role in preventing gastric cancer and various cancers.

4. Onions contain volatile oils and capsaicin with pungent smells, which can remove the fishy and greasy odors in greasy dishes, produce a special aroma, and have a strong bactericidal effect. They can stimulate the secretion of digestive juices and increase appetite. Volatile capsaicin can also slightly stimulate the secretion of related glands when excreted through the sweat glands, respiratory tract, and urinary system, thereby playing a role in sweating, expectorant, and diuresis. It is one of the traditional Chinese medicines for treating colds.

5. Onions can also lower blood lipids, blood pressure and blood sugar. If eaten with mushrooms, they can promote blood circulation.

I believe that with the above discussion, our friends have a deeper understanding of the medicinal value of onions. Of course, what I want to tell you is that in our spare time, we must learn more on some health websites and find out some foods that can counteract onions. In this way, we can avoid their simultaneous appearance in the diet, thereby avoiding more accidents.
