You can also but witch hazel in a bottle at the drug store. You can add it to a bath or sitz bath type thing and soak in it. (dilute it with water) it is very soothing. This is also safe for things like stiches- This was recommended to me after chilbirth and worked great.
I had a hemorrhoid and, besides the ointment prescribed by my doctor, she suggested that I might use a cotton ball soaked in witch hazel. She recommended keeping them cold in the fridge, and then applying the cold wet ball to my anus for 5-10 minutes.
I did this a few times. Fine. Then I left it on for perhaps 25 minutes. I've had a red and burning anus since then. Sigh. Don't do what I did.
