How to use:

3. Earaches and Ear Infections
A traditional remedy for ear pain is to warm a slice of onion, wrap it in cloth or a sock, and place it against the aching ear. The vapors and juices can help reduce inflammation and pain naturally.
4. Chest Congestion and Hyperemia

A mild onion decoction can help relieve infant colic. To make it, boil chopped yellow onion in water, cool, and give a teaspoon to the baby as needed. Always consult your pediatrician before trying any home remedy on infants.
6. Wound Healing and Burns
Onion skins and fresh juice have antiseptic properties. Applying a thin layer to minor wounds, bruises, or burns can help stop bleeding, prevent infection, and speed healing.

An old home remedy for fever is to rub the soles of the feet with coconut oil, place thin slices of onion on them, wrap with gauze, and wear socks overnight. Many claim this method helps draw out toxins and lower temperature, especially in children.

Placing sliced onions around the house or bedroom is thought to absorb bacteria and viruses from the air, helping to purify your environment during cold and flu season.
13. Nausea and Vomiting
For nausea, extract the juice of a grated white or yellow onion. Brew a cup of peppermint tea and allow it to cool. Alternate drinking two teaspoons of onion juice, then after five minutes, two teaspoons of peppermint tea. Repeat until the nausea subsides.
