7. Sea salt
As you probably already know, salt has to dry properties. As a result sea salt can help to dry out poison ivy blisters faster and shorten the length of time it takes to heal from this obnoxious rash. If you live near the ocean or any other body of saltwater, go for a dip! If you aren’t fortunate enough to live near the beach, mix an ounce of sea salt into a quart of water, and apply the mixture to the affected site with a cotton ball. Allow the mixture to dry into the skin.
