Normal saline

Normal saline is a sterile solution of salt (sodium chloride) and water, with a concentration similar to the fluid in our bodies—about 0.9% salt. It is commonly used in healthcare to hydrate patients, clean wounds, or deliver medications intravenously. Because its salt level closely matches that of our blood and tissues, it helps restore fluid balance without disrupting normal bodily functions. Normal saline is safe, versatile, and widely used for medical treatments and procedures.
