Onions are used in most dishes that we eat. They add flavour to foods, and more importantly, they have some impressive benefits to offer. Onions contain numerous minerals and vitamins. These vegetables are used to treat ailments of the skin and hair, and other health issues like diabetes, heart diseases, and inflammation.
But how about consuming onions in the form of their juice? What about eating onion seeds? And is there any use for onion peel? We’ll share everything you need to know in this video.
1. May Boost Hair Health
The sulphur in onion juice boosts collagen production – and this could enhance hair growth as well.
According to one study, onion juice can boost hair growth and treat conditions like alopecia. In the study, people who washed their hair with onion juice experienced more hair growth
Onion juice may also make your hair shinier. The antimicrobial properties of the juice may help fight scalp infections. A healthier scalp means stronger hair follicles.
2. May Fight Acne
The antimicrobial and antifungal properties of onion juice play a role in treating acne.
In one study, a gel containing extracts of onion improved acne scars in patients. This gel improved the appearance of the scar by reducing redness and inflammation.
3. May Delay Wrinkles
The flavonoids and other antioxidant compounds in onion juice may prevent the signs of premature aging. The purported anti-aging properties of onion juice may also be attributed to its sulphur content, which can boost collagen production and fight premature aging. More research is required for us to be certain of these benefits.
4. May Help Reduce Cancer Risk
There are several anticancer compounds in onions. Studies show that these compounds may help in the treatment of several types of cancer. Research also states that the stronger an onion’s flavour, the more effective its role could be in preventing cancer.
5. May Help Treat Diabetes
Onion bulb extract may lower blood glucose levels, which is good news for people with diabetes. The veggie is low in calories and also increases your metabolic rate, helping to manage diabetes symptoms. One study found that intake of onion extract may be effective in lowering plasma glucose levels, which, when high, contribute to diabetes.
6. May Boost Your Immunity
Onions contain selenium, a nutrient that may boost immunity levels. Selenium triggers an immune response and suppresses excessive immune response. Immune cells deficient in selenium are vulnerable to more oxidation, and may face difficulties in producing protein and transporting calcium – hence why it’s so important that we get plenty of selenium on a daily basis.
7. May Enhance Your Vision
The antimicrobial properties of onion juice can help treat eye infections. Sulphur-rich onions are also important for the production of a protein that acts as an antioxidant for the lens of the eye.
8. May Help Treat Nail Fungus
Studies show that the antifungal properties of onion juice can fight fungal infections in humans.
To treat this type of nail fungus, apply the juice to the affected toenail using a cotton ball. You can also secure the cotton ball to the toenail with a bandage or a tape. Leave it on for an hour and then wash the juice off with lukewarm water. You can use this remedy once a week.
9. May Improve Sleep And Mood
Some studies show that the folate in onion juice can improve mood and fight depression. Folate works by preventing the build-up of a chemical that keeps blood and other nutrients from reaching the brain. Excess production of this chemical also interferes with the production of serotonin, the feel-good hormone.
Now, let’s take a look at the benefits of onion seeds.
Onion seeds actually have nothing to do with onions. If you’ve ever grown onions before, you’ll know that they actually grow from other onions – no seeds involved!
Onion seed is actually a flowering plant, and the black seeds produced are known as nigella seeds. If you want to add onion seeds to your diet, try toasting them lightly and grinding them. Some of the most notable benefits of onion seeds are as follows:
