Can salt water be used to wash the skin for itching?

Whether salt water can be used to wash itchy skin depends on the specific circumstances. Generally speaking, if the itchy area of the skin does not show signs of ulceration, using a mild salt water solution for cleaning may be acceptable. Salt water has antibacterial and anti-inflammatory properties, which can reduce bacterial growth on the skin surface, help prevent infection, and possibly alleviate mild inflammatory responses. However, it is important to properly control the ratio of salt to water, as a high concentration may irritate the skin and cause discomfort. If the itchy area has already developed ulcers or is caused by certain skin conditions (such as eczema or urticaria), washing with salt water might worsen symptoms, increase the risk of infection, and even impede the skin's healing process. In such cases, prompt medical attention should be sought, and treatment should follow the doctor's recommendations.
