Apple cider vinegarĀ (ACV) is a home remedy that may offer relief from itching. In addition, it has antibacterial properties, which could help reduce the risk of skin infections that may result from scratching.
Since ACV is acidic, you should be careful when trying it out, especially if your rash contains blisters.
First, dilute the vinegar with a small amount with water, place it on a cotton ball, and dab it on a small patch of skin. If it doesn’t irritate your skin and stops the itch, it may be a good option to try.
