Saline solution is a specific type of salt water, but not all salt water is medical-grade saline. Saline solution typically contains 0.9% sodium chloride and is made under sterile conditions for safe medical use.
In contrast, general “salt water” can vary in concentration and is not necessarily sterile or suitable for medical applications. Saline is carefully formulated to match the body’s natural fluid balance, which makes it appropriate for uses such as wound care, irrigation, and respiratory support.
