Onions are some of the most useful vegetables for cooking, but they also have an important role in boosting the immune system and protecting the body against infections. If you prepare an onion juice poultice or decoction, and then apply it to the site of an open wound, it can help to dry out the wound, preventing the release of pus, and also eliminating any underlying infections that may be causing the festering. By drying out the wound, onion juice actually speeds the healing process and prevents any further microbes from entering and infecting your body.
