3. Immune system

Onions are a good source of vitamins E and C, both of which are essential for our immune system.

Moreover, they are powerful antioxidants and are believed to have anti-aging effects.

Therefore, onions can not only boost your immune system, but also help you stay young and reduce your reliance on expensive face creams or even beauty interventions.

4. Body water content

Onions contain a lot of water; in fact, 90% of an onion is water.

Interestingly, our bodies have acupoints, and the meridians that support organ function pass through these acupoints. These acupoints help the meridians distribute water evenly throughout the body. Placing onions under the feet can help replenish the body's fluids.

This is especially useful if you forget to drink enough water during the day.
