It wasn't me, but I'll take the credit.

I think raw ginger belongs in the food bag or first aid bag.  Excellent health benefits.  If you have a cold, ginger tea will soothe.  If your tummy is queezy, ginger will calm it.  Sore throat, it's an anti-inflam.  Astingent properties promote good oral health, something often neglected by myself in the bush.
