Kava has reduced offensive body odors in me for sure.
I believe the way it works is your body releases waste, like dead skin and stuff that comes out in sweat. Bacteria eat that waste and then poop it out, and it’s not your body or even the wastes that cause that stank, it’s the poop from the lil organisms on your body, or farts or whatever. Kava cuts a lot of their food supply, so they never get to poop it out, so no stink. Then you just smell like what you were supposed to smell like, before the organisms moved in and took over thanks to a big food supply.
