Put an onion in your socks before you go to bed.

Take a red onion, wash it and cut it into slices.
Before going to bed, after washing your feet, put an edge of onion on the soles of your feet.
Use an old sock to cover the foot and make sure the onion stays in its position during the night.
Repeat this system for about 5 consecutive days.
Here are the benefits of sleeping with an onion in socks:

Purifies the blood: onion phosphoric acid helps to absorb toxins and purifies the blood.
Eliminates bacteria, germs and pathogens: the onion contains large antibacterial and antiviral properties.
Purify the air: the onion will limit the bad smell of the feet.
According to the original article, published by Healthy, Wild and Free, you will still have to use a new onion, because keeping the onion slices will ensure that they absorb the toxins and bacteria in the refrigerator.
