I don't know how it does, I only know it does one fantastic job at it.
First of all you should never use an antipersperant because it blocks the skin where you should be perspiring and getting rid of toxins, your underarms. Plus it is right near your lymph nodes and the antipersperant is full of junk that you do not want there.
What you want to use is a natural deoderant. Basically you will still sweat (a good thing) but you won't smell. The deoderant masks any bad smell.
So the herbal foot cream works just like, or I think even better, than a natural deoderant. Remember it is for stinky smelly feet.
I just put a dab on in the morning and carry the purse size with me in case I need to re-apply.
One note though, as you continue to detox, you will smell less and less. You won't have those nasty toxins in you making you smell bad. I've been using the herbal foot cream for years and it works great.
One more thing: When I switched from antipersperant to natural I would get nasty junk on my shirts. Now that I regularly detox no more stains on my shirts. They are clean!
