Hi all
I remember from my archaeology days that some puffball remains were found at the 5000 year-old stone-built village complex Skara Brae in Orkney. Although these were NOT giant puffballs (
Langermannia gigantea) they may have similar properties. They were the smaller puffballs, and as the tough outers were found in abundance they were probably using the inner cotton-wool-like sponge medicinally. I reckon all that sitting on stone might have caused piles - puffballs are ideal for treating them!
The species
Lycoperdon bovista now renamed
Calvatia utriformis (to keep the mycologists in a job) is defined as an astringent & haemostatic as infusion or powdered, and used before it is ripe. I've also read that these when dried can be kept for emergency nosebleeds when the spores can be 'puffed' up the nose direct from the mushroom to stem the bleeding! I carried some for a while but never had a nosebleed...
See
http://www.rogersmushrooms.com/gallery/DisplayBlock~bid~5703.asp as a starting point for this species id. He's just released a smaller volume (still huge!) after 25 years in print, Roger Phillips decided to update it!
Again, sorry for not being specific with the giant puffball, but I hope this helps for future reference...
