Antiseptics != Antibiotics.<p>By similar application we mean completely injested so that it goes into your digestive system and&#x2F;or bloodstream and selectively kills &quot;bad&quot; stuff only, even in low concentrations. That&#x27;s what antibiotics do and that&#x27;s what&#x27;s so great about them.<p>Nobody uses bleach for that. Bleach and alcohol kill everything they touches at high enough concentrations and barely anything if it&#x27;s too low.
