Witch hazel. Ever have your eyebrows threaded and asked if you wanted witch hazel applied?
Witch hazel has other great uses too. It can decrease pain and itching in external hemorrhoids and is safely used for postpartum hemorrhoids and symptoms. You can find it in cooling sprays used for postpartum care that can be pretty $$$$.
All you have to do is soak a pad with witch hazel and place near your anal area.
It's a natural anti-inflammatory and can reduce swelling.
And it's cheap so no need to buy expensive small sprays because most of them contain witch hazel as primary ingredient.
