Ionic silver is an excellent mouthwash and also a good choice for a body deodorant. It is a non-toxic pathogen killer, and it eliminates the bacteria that cause odors. You can put it in a spray bottle for deodorant use.
Of course, if you're outside, hot, and working hard, I don't think much of anything will help; although I suppose some diet modification might be of some use. :D
Thank you for the input. I'll check it out and see what can be done through dieting. We already got rid of so many things. The food table is being modified as we learn
