While a cold compress will do, substances with cooling properties are also effective at relieving the itch. Davis says anything containing essential oils like menthol, camphor, tea tree, eucalyptus, nutmeg, and thymol is best.
“These ingredients have anti-inflammatory properties, helping to reduce pain, swelling, and itching,” he says. “For this reason they are also used in Vicks salve, lineaments, and creams for muscle aches.”
Bordone agrees that Vicks — and even toothpaste — may ease the itchiness. The histamine reaction will still be there, but it'll give you temporary relief, she says. That said, she still cautioned that overuse of any essential oils could lead to allergies and sensitivities.
