Zix is the crap that build up inside a zit. It's very high in natural estrogen. If you take it and mix it with semen from a young Swedish boy, one part zix to four parts semen, and spread it on the affected area it tends to reduce inflammation and promotes regrowth.
Zix is a bit pricey for most who use it. You can get SvenskaJis or Stockhole, which are the same stuff, for about half that.
