How Do You Make Onion Juice?

Before we get to the benefits, we must first know how to prepare onion juice. It is quite simple.

  • Peel about 3 to 4 onions and chop them into pieces.
  • Add the pieces to a juicer and extract the juice.

  • You can also add the pieces to a blender and take the paste.

What Are The Benefits Of Onion Juice?

1. Treats Cancer

There are several anticancer compounds in onions, including quercetin, anthocyanins, and organosulfur. Studies show that these compounds help prevent several types of cancer (1).

Research also states that the stronger an onion’s flavor, the more effective it is in preventing cancer.

Quercetin had also shown to cut the risk of brain and lung cancers. Onions also contain fiber, which helps cut the risk of colon cancer. This is especially true if the juice is made of red onions (2). They destroy tumor cells, and this is how they aid cancer treatment and prevention.

2. Onion Juice Helps Treat Diabetes

Onion bulb extract can lower blood glucose levels, and that is good news for people with diabetes.

The veggie is low in calories and also increases your metabolic rate, and this can help manage diabetes symptoms (3).

And as per another Korean study, intake of onion extract can be effective in lowering plasma glucose levels (4).

3. Fights Inflammation

The quercetin in onion juice has shown to inhibit leukotrienes, prostaglandins, and histamines – all of which are known to cause inflammation in osteoarthritis (5).

An Iranian study showed similar results. Rats going through acute and chronic stages of inflammation, when ingested with onion juice, showed improvement in their condition. Fresh onion juice was found to inhibit both acute and chronic pain and inflammation, with a greater effect on inflammation alone (6).

Onion juice intake can also prevent bone disorders associated with inflammation. Studies show how taking the juice can boost bone mineral density in postmenopausal women (7).

4. Onion Juice Boosts Your Immunity

Onions contain selenium, which is why the juice can boost your immunity. Selenium triggers an immune response and suppresses excessive immune response (8).

Also, immune cells deficient in selenium are vulnerable to more oxidation. These cells also face difficulties in producing protein and transporting calcium.

Onion juice also helps in treating asthma and other respiratory ailments (9). It stimulates the excretory organs and strengthens them – including the lungs.

The quercetin in onion juice fights inflammation and other allergies (10).

5. Enhances Your Vision

The antimicrobial properties of onion juice can help treat eye infections like conjunctivitis and blepharitis. Experiments done on rabbits found that the juice can have an inhibitory effect on the growth of eye flora (11).

The juice can also prevent cataracts. In an Iranian study, instilling onion juice prevented selenite-induced cataract formation (12).

6. Helps Treat Nail Fungus

Studies show the antifungal properties of onion juice (aqueous extracts of onions) can fight Candida albicans, a pathogenic yeast that causes fungal infections in humans (13).

Using the juice for this purpose is quite simple and effective. 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. Pat dry. Follow this once a week.

7. May Cure Your Ear Infection

A report published by the Cambridge University Press speaks highly of the ability of onion juice in treating ear infection and earache (14).

We need more research in this regard, though. Please consult your doctor before using the juice for this purpose.

8. May Improve Sleep And Mood

There is more research required here as well. But some studies show how the folate in onion juice can improve mood and fight depression (15).

Folate works by preventing the build-up of homocysteine, a chemical that keeps blood and other nutrients from reaching the brain. Excess production of homocysteine also interferes with the production of serotonin, the feel-good hormone.

Other hormones like dopamine and norepinephrine also help regulate sleep, and this is where the folate in onions comes into the picture. It supports the production of these hormones in the body (16).

9. Improves Fertility

Studies show how the juice can increase testosterone levels. This can be attributed to the antioxidant activity of onions, which promotes sperm health. In a Jordanian study, ingesting onion juice to male rats improved their testosterone levels (17).

In yet another study, onion juice had shown to improve copulatory behavior in sexually potent male rats (18). The juice had achieved this by boosting serum testosterone levels.

10. Onion Juice Fights Acne

The antimicrobial and antifungal properties play a role here.

In a study, a gel containing extracts of onion had improved acne scars in patients. This extract improved the appearance of the scar by reducing redness and inflammation. The study concluded by stating that onion extracts could be used as potential treatment options for bacterial and fungal infections (19).

Apply onion juice to your face and leave it on for 10 to 15 minutes. Wash your face with warm water. But be careful – don’t let the juice get into your eyes. Also, ensure not to apply the juice on open blisters. And if you have sensitive skin, please consult a doctor before you use the juice.

Some sources also suggest that the juice can aid treatment of psoriasis. We need further research on this, however.

11. May Delay Wrinkles

This also has limited research. The flavonoids and other antioxidant compounds in onion juice may prevent signs of premature aging.

The purported anti-aging properties of onion juice may also be attributed to its sulfur content, which, as per some sources, can boost collagen production and fight premature aging. More research is warranted, though.

12. Boosts Hair Health

As we saw, the sulfur in the juice also boosts collagen production – and this enhances hair growth as well.

According to an Iraqi study, the juice can boost hair growth and treat conditions like alopecia areata (sudden hair loss). Individuals washing their hair with onion juice experienced more hair growth (20).

Onion juice may also make your hair shinier. And the antimicrobial properties of the juice can help fight scalp infections. A healthier scalp means stronger hair follicles.

These are the different ways onion juice can benefit you. But hold on – does drinking the juice have any side effects?

What Are The Side Effects Of Onion Juice?

  • Possible Issues During Pregnancy And Breastfeeding

Since there is not enough research here, we suggest pregnant and breastfeeding women consume onion juice in limited amounts. Consult your doctor for more information.

  • Might Lower Blood Sugar Way Too Much

Onion juice can lower blood sugar (21). So, if you are someone who is already on diabetes medications, the juice can lower your blood sugar levels way too much. Please check with your doctor – they may adjust the dosage accordingly.

  • May Cause Bleeding Disorders

As onion (juice) may slow down blood clotting, it can increase the risk of bleeding (22). If you have a bleeding disorder, don’t consume onion juice. This is one reason you should also avoid onion juice at least two weeks before a scheduled surgery.

  • May Aggravate Indigestion

If you are already suffering from indigestion, be wary of onion juice as it can aggravate the condition.

  • Skin Allergies

This can happen with sensitive skin. Please do a patch test before you apply onion juice to your skin.
