The Healthy Properties of Onions

Diuretic properties

One of the most well-known properties of onions is their diuretic ability.
This is why onions are highly recommended to patients who suffer from kidney issues, gout, kidney stones, edema, or hypertension.

This is mainly because of their diuretic effect. However, it’s also due to their high content of water and fiber and low amounts of fat and sugar.


An Amazing Detox Diet to Cleanse Your Kidneys

They’re great at treating and preventing diseases

Onions also work as an expectorant and help to kill bacteria and fungus.

Onions are wonderfully useful for people who suffer from colds, the flu, bronchitis, pharyngitis, and other respiratory illnesses.

In recent years, onions have also shown their beneficial effect in the treatment of asthma and allergies.

Onions are also a powerful heart protector, thanks to their anti-thrombosis, hypo-lipidemic (this is the ability to lower levels of cholesterol and triglycerides in your body), and hypo-tensive properties.

They help your digestion

The most well-known of the purifying abilities of onions is most likely their ability to remove toxins that are produced in the stomach during digestion. This a process that also serves to stimulate your liver, pancreas, and vesicle in order to allow them to secrete the necessary substances.

However, these properties only work if you eat raw onions.


Although onions are great, you should avoid eating them too much if you:

  • Have a weak stomach,
  • Suffer from acid reflux,
  • Have a tendency towards flatulence or excessive gas.

The benefits of eating onions are innumerable, and we haven’t gone over all of them!

Because onions are so beneficial, you should try to eat them daily in any form, but preferably raw. This way, you’ll be able to conserve and enjoy all of their beneficial properties.
