moss at wound dressing in WWI?

Ok, a host of questions from the quote below, but mainly:

  1. Did WWI soldiers (or others with wounds) really do this? (What region of the war front?)
  2. Is the finding true?

“…World War I soldiers whose wounds were packed in moss had a higher survival rate than those who had their wounds wrapped with cotton.”

Anybody? Moss as wound dressing seems a good Q for the Master, no?

I’ve used moss as a field dressing. I was in a forest and cut myself badly with a knife (an accident caused by extreme stupidity, the details of which I don’t want to revisit). I was bleeding profusely and had almost a mile to walk back to the car. A handful of moss was convenient, sterile and effective at staunching the bleeding.

Interesting. Moss is really sterile?

An instructor of mine once told us that people used spagnum moss as sanitary napkins back in the day.

Did they have a higher survival rate than those who used cotton?
