You Can Use It for Wound Cleaning
Infections kill fast when doctors and antibiotics are gone. Salt water—called saline—is one of the oldest wound care methods. A mild salt solution can clean cuts, scrapes, and bites. It reduces bacteria, washes out debris, and helps wounds stay clean. It’s no substitute for stitches or antiseptics, but it’s better than nothing. All you need is boiled water and clean salt. A saline rinse also helps soothe sore throats and nasal infections. You’ll want salt ready in any medical kit. Even just rinsing a wound with saltwater could prevent deadly infection when help is days or weeks away.
