I am a big fan of ginger. That stuff sits in the ground for months on end, you dig it up and leave it in a cupboard for months and still no bacteria grow on it. It's also really good for inflammation after a tough run or workout. It gets a mention in the natural medicine link. TBH though conventional medicine has saved my life on a couple of occasions so if I was struggling I would take the nuclear option as a last resort and worry about my symbiotic bacteria later.
