After hours of indescribable torture and trying many other natural remedies including those listed above, I managed to find on one site where someone mentioned rubbing alcohol works, and believe me it does, I was hesitant at first thinking it would burn and sting, but in fact has the opposite effect and cools and calms the skin. Being rubbing alcohol I wouldn't generally advise as a natural cure but if you ever are unfortunate to get the dreaded hell's itch then you will be thanking me greatly, because it is pure torture like nothing else. Just try a small bit on an area first to ensure you have no adverse reaction. In Australia I used one called Isocol which is rubbing alcohol and water.
Good Luck.
