If you have a wound in your body that hasn't healed in a long time, apply onion oil. Onion oil is antibacterial and anti-fungal. It works like an ointment on the wound, allowing it to heal quickly.

Onion oil is beneficial in cold-fever

Cold weather is typical, with weather changes (particularly after rain). If you are coughing, apply onion oil to your chest while resting at night.
