You're right, moss could be used and in absolute necessity I would. I also think it comes down to your own personal experience of periods because women experience them very differently both on a psychological and physical level. I've always hated mine, because I end up losing my mind for a couple of days every month and it's not the most pleasant emotional ride to have to go through 52 times a year. Also, every woman's flow is different, some experience heavier times and others light, and some can never predict. If I could bank on my body being predictable then maybe I'd be tempted to experiment? And I'd have to consider who's company I was in if I was going to because if it didn't work well enough, for whatever reason, I wouldn't want them to be embarrassed and I think for some embarrassment is a huge issue. The culture we live in teaches women to hide their periods, to make them 'clean and tidy', so that no one knows that it's happening, and as such, it has permeated our entire relationship to a perfectly natural bodily process. Hence people don't talk about it, and women rarely mention/talk about it infront of men unless they're in a relationship with them. I find it interesting that in the bits and bobs about bushcraft I have seen/read so far there isn't anything that I can recall that related to periods which, when you think about it is completely mad since it's something that occurs as often as the full moon for about 50% of the population. I would dearly like to hear it mentioned on bushcraft courses...as something to be considered as naturally as 'how to make fire!' I know it's not a survival issue necessarily, but for women it's a very personal and pertinent issue. I'm so very glad that Emma posted this thread. Now, does anyone know of any other things apart from moss that might be useful - and for stomach aches too!
