Sphagnum moss: a surprising medical treatment from WWI (and 900 years before that, too)

My family recently read a children's chapter book about a British mouse who becomes a hero during WWII called Umbrella Mouse.  It's a fictionalized story of course, but a major theme is the less well-known stories of the many animals who served in war including dogs, horses, and pigeons. 

Another interesting part of the story introduced the use of spiderwebs and sphagnum moss as wound dressings and/or alternatives to cloth bandages. Turns out sphagnum moss has been used for over 1,000 years to treat and dress wounds. It also has properties that help preserve bog bodies and even sequester carbon. A 2017 article in Smithsonian magazine delves deeply into this little green plant some call an "unlikely savior".
