We have already discussed the way Witch Hazel can improve acne, blemishes, itching, and other skin related issues, but it can also be useful in relieving pain due to exposure from Poison Ivy or Poison Oak. Witch Hazel will reduce the amount of inflammation and also prevent itching, which if scratched, will spread and may even induce scarring. For your next camping trip, it’s not a bad idea to pack some witch hazel in the same way you would pack insect repellant.
