I had had this thought, that the odor is from bacteria breaking down, and the thought was to work at killing the bacteria. I had some colloidal silver spray, and used that, and darned if it didn't work. I've been drinking more than one cup of decaf a day, and switched to one at work by Peets that isn't swiss water processed. STINKO! So what we eat/drink effects it. I had the thought, now that I am drinking Cistus tea to try this under my arms as an experiment. Why?
