5 most significant healing properties

1. Protects the vascular health

The onion is an excellent agent for the protection from thrombus as it abounds inĀ anticoagulant compounds.

Heart patients are recommended to eat onions every day because their ingredients prevent the build up of platelets and speed up the process of their breaking down.

Eating onions with fatty food helps block harmful effects of fats, inluding the formation of thrombus.

The raw onion is the best remedy for raising the “good” HDL cholesterol. It takes just a half of raw onion per day, since it does not affect cholesterol if thermically processed.

The research shows HDL cholesterol went up by 30%, and the therapy was successful in 70% volunteers.

The sulphur compounds from the onion also help lower elevated triglycerides and relax blood vessels.

The onion cuts the risk of high blood pressure, coronary artery disease, peripheral vascular disease and heart attack.

2. Regulates sugar and protects from diabetes

Medicine recognized long ago the effectiveness of onions in blood glucose regulation. The effect is noticed even with small quantities, when the onion is used as an addition to the main course.

Research have confirmed that frequent onion consumption can be associated to lower blood glucose levels, whether the onion is cooked or raw.

Its active principle has been attributed to compounds allyl-propyl-disulfide and allicin, which stimulate insulin secretion.

The onion contains manganese and chromium – two elements indispensable for proper insulin secretion and action.

3. Significantly helps with cancer

More than 30 anticarcenogenic compounds have been discovered in onion, such as sulfide, quercetine and ajoens. It is believed they slow down tumour growth and protect from free radicals.

It is especially recommended in case of esophagus, stomach, intestinal and prostate cancer since it has been shown that a frequent onion consumption is associated with a lower rate of these cancer types.

4. Brings peaceful sleep and good mood

The folic acid found in onions may help against depression as it prevents the formation of homocystein in the body, which could prevent the supply of nutrients to the brain.

Excess homocystein obstructs the production of serotonin, dopamine and norepinephrine, which regulate sleep and appetite as well as mood.

5. Strengthens bones, hair and nails

Osteoporosis is frequent in postmenopausal women, but a healthy diet can prevent it.

An extensive study on women over 50 found that regularly eating onion was correlated to a greater bone density.

The research also showed that menopausal women who ate onion daily had a lower risk of hip fracture.

A high sulphur concentration can benefit the connective tissue since sulphur is necessary for the formation of that tissue.

A regular application of onion juice on the scalp will speed up hair growth, while daily rubbing of onion juice into nails will strengthen weak and fragile nails.

The onion extract is particularly effective in diminishing scars. Cremes based on its extract are recommended after surgeries of hypertrophic and cheloid scars.
